The Business Lingo Guide: Essential Terms Every Online Entrepreneur Should Know

Online business reports often combine financial figures with marketing abbreviations such as CTR, CPC, CPA, ROAS, CAC, and LTV. Understanding their definitions is useful; understanding how they connect is what helps you make better decisions.

A campaign reporting a 2.1% click-through rate, $0.84 cost per click, $21 cost per acquisition, and 3.7× return on ad spend may look promising. However, those figures cannot establish profitability without the relevant costs, customer value, conversion definitions, and reporting assumptions.

This guide explains the terms used in online business, advertising, sales, analytics, and marketing. The examples are hypothetical and illustrate calculations rather than typical results or earnings expectations.

Evaluate each metric in the context of your business objective, costs, and customer behavior.

1. Core Business and Financial Terms

Revenue

Revenue is income generated from selling products or services before deducting the associated business expenses. Selling 100 products for $50 each produces $5,000 in sales revenue, assuming no discounts or returns. Revenue is not the same as profit or cash received.

Gross Revenue and Net Revenue

Gross revenue generally refers to sales before applicable reductions. Net revenue reflects deductions such as returns, discounts, and allowances. Use a consistent definition when comparing periods or reports, and avoid deducting the same adjustment twice.

Gross Profit and Net Profit

Gross profit = Net sales revenue − Cost of goods sold.

Gross profit shows what remains after the cost of the goods sold. Net profit, also called net income, accounts for the remaining applicable expenses, including operating costs, interest, and taxes. If revenue is $10,000 and all applicable expenses total $8,000, net profit is $2,000.

Neither measure necessarily represents cash available for the owner to withdraw. Payment timing, inventory purchases, debt repayments, and other commitments affect available cash.

COGS — Cost of Goods Sold

COGS includes costs assigned to the goods actually sold during the period. These may include purchased inventory or direct materials and production labor. Service businesses may use a related measure called cost of services or cost of revenue.

If an item sells for $100 and its COGS is $40, gross profit is $60. Advertising and other operating expenses still need to be considered.

Gross Margin and Net Profit Margin

• Gross margin = Gross profit ÷ Revenue × 100.
• Net profit margin = Net profit ÷ Revenue × 100.

Gross profit of $60 on $100 in revenue gives a 60% gross margin. Net profit of $1,500 on $10,000 in revenue gives a 15% net profit margin. Specify the profit measure when using the phrase “profit margin.”

Margin and Markup

Margin compares profit with the selling price. Markup compares the difference between selling price and cost with the cost.

• Margin = (Selling price − Cost) ÷ Selling price × 100.
• Markup = (Selling price − Cost) ÷ Cost × 100.

An item costing $50 and selling for $100 has a 50% margin and a 100% markup. These percentages measure different relationships. Margin is undefined when the selling price is zero; markup is undefined when cost is zero.

Use the Wares Point Profit Margin Calculator to compare pricing and entered costs. The result only accounts for the expenses included in your inputs.

OPEX — Operating Expenses

Operating expenses are costs of running the business beyond those classified as cost of sales. Examples can include administrative salaries, marketing, office rent, insurance, and software subscriptions. Classification depends on how the expense is used.

CAPEX — Capital Expenditures

Capital expenditures are investments in assets expected to provide benefits over a longer period, such as equipment or significant improvements. Qualifying expenditures are generally recorded as assets, with their cost recognized over time through depreciation or amortization where applicable.

Fixed Costs, Variable Costs, and Overhead

Fixed costs generally remain unchanged within a defined period and activity range. Variable costs change with sales or production volume. A flat software subscription may be fixed, while a transaction fee varies with sales. Some expenses contain both components.

Overhead refers to indirect costs of supporting business operations. It is not automatically synonymous with fixed costs; some overhead varies with activity.

Contribution Margin

Contribution margin is revenue remaining after variable costs. It contributes toward covering fixed costs and generating profit.

• Contribution margin = Revenue − Variable costs.
• Contribution margin ratio = Contribution margin ÷ Revenue × 100.

State which costs are included. If advertising is excluded from your contribution calculation, the result shows what is available before advertising, fixed costs, and profit requirements.

Break-Even Point

The break-even point occurs when revenue equals the costs included in the analysis. For a simple single-product model:

Break-even units = Fixed costs ÷ (Selling price per unit − Variable cost per unit).

This assumes a positive contribution per unit and consistent prices and costs. Round up when whole units are required. Breaking even before overhead or taxes is different from breaking even across the entire business.

Cash Flow

Cash flow describes actual cash moving into and out of a business. Positive net cash flow means inflows exceed outflows during the period; negative net cash flow means the reverse.

Profit and cash flow differ. A profitable business can face a cash shortage when customers pay late, inventory requires upfront payment, or other obligations fall due.

Burn Rate and Runway

Gross burn usually describes cash expenditure over a period. Net burn describes the rate at which cash decreases after incoming cash is considered.

Estimated runway = Available cash ÷ Monthly net cash burn.

A business with $30,000 available and a steady $5,000 monthly net cash burn has approximately six months of runway. An accounting loss alone is insufficient to calculate cash runway.

Assets, Liabilities, and Equity

Assets are resources controlled by the business. Liabilities are obligations it owes. Equity is the residual interest after liabilities are deducted from assets.

Assets = Liabilities + Equity.

Working Capital

Working capital = Current assets − Current liabilities.

This measures short-term resources relative to short-term obligations. It is not the same as the cash balance, because current assets may include receivables and inventory.

Accounts Receivable and Accounts Payable

Accounts receivable (AR) generally represents amounts customers owe the business. Accounts payable (AP) generally represents unpaid amounts owed to suppliers for goods or services received.

Fiscal Year, Quarters, YoY, and MoM

A fiscal year is a business’s annual accounting period and may differ from the calendar year. Q1, Q2, Q3, and Q4 refer to its four quarters.

Year-over-year (YoY) compares a period with the equivalent period in the previous year. Month-over-month (MoM) compares one month with the preceding month.

Growth rate = (Current value − Previous value) ÷ Previous value × 100.

Revenue increasing from $10,000 to $12,000 represents 20% growth. Percentage growth is undefined when the previous value is zero and needs careful interpretation when the baseline is negative.

ROI — Return on Investment

ROI compares the net gain from an investment with its cost.

ROI = Net gain attributable to the investment ÷ Investment cost × 100.

If a $1,000 investment returns $2,500 after other relevant costs, the net gain after the original investment is $1,500. ROI is therefore 150%. A return of $1,500 before recovering the $1,000 investment would instead produce a $500 gain and 50% ROI.

2. Digital Advertising Metrics

Advertising metrics describe different stages of exposure, response, conversion, and revenue. Compare figures from the same reporting period and use consistent definitions of clicks and conversions.

Impressions, Reach, and Frequency

An impression is a recorded display of an advertisement. Reach estimates the distinct people or accounts exposed to it under the platform’s measurement rules. One person can generate several impressions.

Average frequency = Impressions ÷ Reach.

100,000 impressions and a reach of 50,000 give an average frequency of two. This average does not mean every person saw the advertisement exactly twice.

CTR — Click-Through Rate

CTR = Clicks ÷ Impressions × 100.

2,000 clicks from 100,000 impressions produce a 2% CTR. Check whether the report counts all clicks, link clicks, or another click type. CTR measures response to an advertisement, not the profitability of the resulting traffic.

CPC — Cost Per Click

Average CPC = Advertising spend ÷ Clicks.

$1,000 spent for 2,000 clicks produces a $0.50 average CPC. Lower-cost clicks are useful only if they contribute to the intended outcome.

CPM — Cost Per Mille

CPM is cost per 1,000 impressions.

CPM = Advertising spend ÷ Impressions × 1,000.

$1,000 spent for 100,000 impressions produces a $10 CPM. Audience, placements, geography, competition, seasonality, and campaign objectives can affect impression costs.

CPA — Cost Per Action or Acquisition

CPA = Relevant campaign cost ÷ Recorded actions or acquisitions.

The action may be a purchase, lead, registration, or another configured conversion. $1,000 spent for 50 purchases gives a $20 cost per purchase. It only represents cost per new customer if those conversions are verified new customers.

CPL, CPE, and CPI

• CPL — Cost per lead: relevant spend divided by leads generated. $500 for 100 leads gives a $5 CPL.
• CPE — Cost per engagement: relevant spend divided by recorded engagements. Check the platform’s engagement definition.
• CPI — Cost per install: relevant spend divided by recorded application installs.

Conversions and Conversion Rate

A conversion is a defined valuable action, such as a purchase, account registration, completed lead form, or trial signup. A conversion does not necessarily represent revenue.

Conversion rate = Conversions ÷ Defined eligible population × 100.

100 purchasing sessions from 2,000 eligible sessions give a 5% session purchase conversion rate. State whether the denominator is clicks, sessions, users, or another population, and whether conversions count people, sessions, or events. Event-based rates can exceed 100% when several conversions occur per interaction.

Link Clicks and Landing Page Views

A link click does not guarantee the destination loaded. Loading failures, early abandonment, consent choices, and measurement differences can create discrepancies between recorded clicks and landing page views.

Attribution and Attribution Windows

Attribution assigns credit for a conversion to marketing interactions. An attribution window defines how long an eligible interaction can receive credit for a later conversion.

A customer may see an advertisement, return through search, and purchase after an email. Different models may credit different interactions. Attributed results do not, by themselves, establish that advertising caused an additional sale.

3. ROAS and Advertising Profitability

ROAS — Return on ad spend = Attributed advertising revenue ÷ Advertising spend.

$2,000 in attributed revenue from $500 in advertising gives 4× ROAS, also expressible as 400%. This means $4 in attributed revenue per $1 of advertising spend.

ROAS is not profit. If those sales involve $1,600 in other costs, subtracting the $500 advertising bill produces a $100 loss before any additional excluded costs.

For a simplified model, let the contribution margin before advertising be revenue minus other variable costs, expressed as a fraction of revenue:

Break-even ROAS before fixed costs = 1 ÷ Contribution margin fraction before advertising.

At a 40% contribution margin before advertising, the simplified break-even ROAS is 2.5×. This does not cover fixed overhead or a desired profit. Product mix, discounts, refunds, and attribution errors can change the required result.

4. Customer Economics

CAC — Customer Acquisition Cost

CAC = Defined acquisition costs ÷ New customers acquired.

CAC commonly includes relevant sales and marketing expenditure, potentially including labor and tools. State which expenses and channels are included, and account for the delay between acquisition spending and completed sales. A platform’s purchase CPA is not automatically the same as CAC.

LTV / CLV — Customer Lifetime Value

LTV estimates customer value over the relationship. Some models estimate lifetime revenue; others estimate gross profit or contribution. Identify the model before comparing LTV with CAC.

$50 spent each month for three years produces $1,800 in customer revenue. It does not establish $1,800 in profit. Delivery, support, refunds, retention costs, and the likelihood of continued purchases matter. Base acquisition decisions on supported assumptions rather than hoped-for repeat sales.

AOV — Average Order Value

AOV = Defined order revenue ÷ Number of orders.

$10,000 across 200 orders gives a $50 AOV. Specify how discounts, refunds, taxes, and shipping are treated.

ARPU and ARPPU

ARPU — Average revenue per user divides revenue by the defined user population. ARPPU — Average revenue per paying user uses paying users only. Use matching periods and clearly define the user count.

Repeat Purchase Rate, Retention, and Churn

Repeat purchase rate measures the share of eligible customers who make another purchase within the defined observation period. Customer retention measures how many customers in a starting group remain active under your criteria.

Customer churn measures customers lost from that starting group during the period. Revenue churn measures a different outcome: recurring revenue lost. Revenue retention may also reflect expansion or contraction, so it should not be substituted for customer retention.

Refund Rate and Return Rate

Refund and return rates measure how frequently transactions are refunded or goods returned. Specify whether you count orders, items, customers, or monetary value. A partial refund, full refund, and returned item may affect reports differently.

5. Connecting CAC, AOV, Margin, and LTV

Consider a hypothetical business with a $25 CAC, $75 first-order value, and a 50% gross margin.

• First-order gross profit: $75 × 50% = $37.50.
• Remaining after acquisition cost: $37.50 − $25 = $12.50.

The remaining $12.50 must still cover any other costs excluded from those figures. Future orders may improve customer economics, but only if customers return and the associated revenue exceeds delivery and retention costs.

6. Sales Terminology

Leads, Prospects, and Customers

• Lead: a potential customer identified through an inquiry, response, or another source.
• Prospect: a potential buyer considered suitable for the offer.
• Qualified lead: a lead meeting defined fit or readiness criteria.
• Customer: someone who has purchased.
• Repeat customer: someone who has purchased again.

MQL and SQL

A marketing-qualified lead (MQL) meets the business’s criteria for marketing interest or fit. A sales-qualified lead (SQL) meets its criteria for direct sales engagement. These definitions vary by organization.

Funnels and Sales Pipelines

A marketing or sales funnel represents stages from awareness through consideration and conversion. A sales pipeline tracks identifiable opportunities as they progress through sales stages.

• TOFU — Top of funnel: awareness and early exploration.
• MOFU — Middle of funnel: consideration and evaluation.
• BOFU — Bottom of funnel: decision-making and conversion.

Close Rate, Lead-to-Customer Rate, and Sales Cycle

Close rate measures the share of defined opportunities that become sales. Lead-to-customer rate measures the share of a defined lead group that becomes customers. Use cohorts with adequate time to complete the buying process.

The sales cycle is the sequence and duration of moving from an opportunity to a completed sale. A deal is a sales opportunity or transaction, depending on the system.

Upsells, Cross-Sells, and Downsells

• Upsell: an offer for an upgraded or higher-value version.
• Cross-sell: an offer for a complementary product or service.
• Downsell: a lower-priced or reduced-scope alternative.
• Order bump: an optional additional offer presented around checkout.

Lead Magnets and Offer Types

A lead magnet offers a useful resource to encourage an inquiry or signup. An introductory paid offer, sometimes called a tripwire, aims to turn an interested prospect into a customer. The core offer is the primary product or service; a backend offer is an additional offer made later in the relationship.

MRR and ARR

Monthly recurring revenue (MRR) normalizes ongoing subscription revenue to a monthly amount. Annual recurring revenue (ARR) expresses recurring revenue on an annual basis; in a consistent model, ARR is commonly calculated as MRR × 12.

These are recurring-revenue measures, not necessarily cash collected or accounting revenue recognized during that period. Define how discounts, variable usage, unpaid subscriptions, and one-time charges are treated.

7. Website and Analytics Terminology

Users, Sessions, and Views

Users are identities distinguished by the analytics system. A reported user is not necessarily a uniquely identified human; devices, browsers, consent, and identity settings affect measurement.

A session groups interactions under the platform’s rules. Views count page or screen displays, including repeat views. One user can generate several sessions and many views.

New and returning users reflect recognized interaction history. “Unique visitors” is a related term whose exact definition depends on the tool.

Engagement Rate, Bounce Rate, and Engagement Time

Engagement definitions vary by platform. In Google Analytics 4, engagement rate is the share of sessions classified as engaged, and bounce rate is the share not classified as engaged. These rates complement one another.

GA4 classifies engagement using session duration, key events, or multiple page or screen views. Check the current configuration rather than assuming that a one-page visit is always a bounce. Average engagement time reflects tracked active engagement, not simply elapsed time since arrival.

Traffic Source and Medium

Source identifies a traffic origin, while medium describes how the traffic arrived. For example, a source may be a search engine and the medium may be organic search or paid search.

• Organic search traffic: visits attributed to unpaid search results.
• Paid traffic: visits attributed to paid promotion.
• Referral traffic: visits attributed to links on other websites.
• Direct traffic: visits attributed without another qualifying source. This does not always mean someone typed the URL.

UTM Parameters

UTM parameters are URL tags used to identify campaign source, medium, campaign name, and other details. Consistent naming makes reports easier to compare. Avoid placing personal information in campaign URLs.

Landing Pages, Exit Pages, and Events

A landing page is the first page in a visit or campaign experience. An exit page is the last tracked page before the visit ends. Events record interactions such as button clicks, submissions, downloads, and purchases.

A valuable event may be labeled a conversion or key event, depending on the platform. GA4 uses “key event” for marked important events, while Google Ads has its own conversion definitions.

First-Touch, Last-Touch, and Multi-Touch Attribution

First-touch models credit the first eligible interaction. Last-touch models credit the final eligible interaction under their rules. Multi-touch models distribute credit across interactions. Model selection, tracking coverage, and attribution windows can change the reported result.

8. Assessing Traffic Quality

Suppose one website attracts 10,000 visitors but no customers, while another attracts 500 visitors and 25 customers. For a sales objective, the second produces a more useful observed result, assuming the customers and their economics are comparable.

Evaluate traffic against the intended goal. Qualified inquiries, subscriptions, support resolution, or awareness may be appropriate objectives for other pages. Traffic volume alone cannot establish business value.

9. SEO Terminology

SEO, SERPs, Keywords, and Queries

Search engine optimization (SEO) improves a website’s accessibility, relevance, and discoverability in unpaid search. A search engine results page (SERP) displays results for a search.

A keyword is a term marketers analyze or target. A search query is what a person actually enters. Search intent describes the task or information that person wants.

Search Volume, Keyword Difficulty, and Ranking

Search volume is an estimate of searches over a defined period and market. Keyword difficulty is generally a tool-specific estimate of ranking competition. Neither guarantees traffic.

Organic ranking is a page’s position for a query under particular search conditions. It can vary by location, device, time, and other factors.

Backlinks, Referring Domains, and Authority Scores

A backlink points to your site from another website. A referring domain is an external domain containing such a link; one domain can supply several backlinks.

Domain Authority and similar scores are proprietary third-party metrics. They are not official Google ranking scores and should not be treated as definitive assessments of quality.

Internal Links, External Links, and Anchor Text

Internal links connect pages on the same website. External links point to another website. Anchor text is the clickable wording of a link; descriptive wording helps readers understand its destination.

Title Tags and Meta Descriptions

A title tag supplies the HTML page title. A meta description summarizes the page in metadata. Search engines may use these when presenting results, but they may generate different titles or snippets.

Canonical URLs

A canonical declaration identifies a preferred version among duplicate or substantially similar pages. It is a signal to search engines rather than a guaranteed instruction. It does not redirect visitors.

Crawling, Indexing, and Sitemaps

Crawling is the discovery and retrieval of pages. Indexing is processing content for inclusion in a search index. Crawling does not guarantee indexing, and indexing does not guarantee a prominent ranking.

A sitemap helps search engines discover URLs. It does not guarantee that those URLs will be indexed.

Robots.txt and Noindex

Robots.txt provides crawler-access rules. It is not a security mechanism or a reliable way to keep a URL out of search results.

A noindex directive requests exclusion from the index of a search engine that supports it. The crawler generally needs access to the page to see that directive. Use authentication to protect private content.

Nofollow and Related Link Attributes

Nofollow communicates a link relationship to search engines. Google also supports sponsored for paid relationships and ugc for user-generated links. These attributes do not prevent people from following a link or substitute for a clear affiliate disclosure.

Long-Tail Keywords and Search CTR

Long-tail keywords have relatively low individual search demand and often express specific needs; they are not defined simply by word count. Search CTR divides clicks from search results by the relevant result impressions.

10. E-Commerce Terminology

Cart and Checkout Abandonment

Cart abandonment refers to carts that do not lead to completed purchases. Checkout abandonment concerns shoppers who begin checkout but do not finish. Define the observation window and population before calculating either rate.

Add-to-Cart Rate and Purchase Conversion Rate

These measure the share of eligible users or sessions that add an item to a cart or complete a purchase. Use consistent populations and distinguish events from unique users or sessions.

ASP — Average Selling Price

ASP = Relevant product sales revenue ÷ Units sold.

ASP measures price per unit; AOV measures revenue per order. An order containing multiple items can make these figures substantially different.

SKU and Inventory Turnover

A stock keeping unit (SKU) is a business’s identifier for an inventory item or variant. Inventory turnover measures how often inventory is sold through during a period.

Inventory turnover = COGS ÷ Average inventory valued at cost.

GMV — Gross Merchandise Value

GMV measures transaction value processed through a marketplace or platform according to its definition. It is different from the marketplace’s own revenue and profit. Check the treatment of cancellations, returns, shipping, and taxes.

Fulfillment and Dropshipping

Fulfillment covers order preparation and delivery. In dropshipping, a supplier generally holds inventory and ships orders for the seller. The seller still needs to manage the customer experience, supplier performance, returns, and workable margins.

Refunds, Chargebacks, and Recurring Orders

A refund returns transaction funds to a customer. A chargeback is a payment reversal through the card dispute process and differs from an ordinary merchant-issued refund.

Subscriptions and recurring orders produce transactions under an ongoing arrangement. Revenue depends on continued payment and retention.

11. Marketing Terminology

CTA, USP, and UVP

A call to action (CTA) directs the next step, such as requesting a quote or joining a newsletter. A unique selling proposition (USP) identifies a meaningful distinction from alternatives. A unique value proposition (UVP) explains the value an offer provides to a customer.

KPI — Key Performance Indicator

A KPI is a measure selected to evaluate progress toward an objective. A dashboard can contain many metrics while only a few are appropriate KPIs for the current goal.

ICP, Target Audience, and Buyer Personas

An ideal customer profile (ICP) describes a suitable customer or organization, particularly in business-to-business selling. The target audience is the group the marketing aims to reach. A buyer persona represents a customer type using evidence about needs, behavior, and decision-making.

Market Segments, Niches, and Positioning

A market segment groups customers with shared characteristics. A niche is a narrower area of specialization. Positioning communicates how an offer fits a customer need and differs from alternatives.

Brand Awareness and Brand Equity

Brand awareness describes familiarity with a brand. Brand equity is the value associated with the brand’s recognition, reputation, associations, and customer relationships.

Marketing Channels and Methods

• Organic marketing: distribution without paying directly for the placement or reach. Content creation and staff time still have costs.
• Paid marketing: purchased advertising, placements, sponsorships, or promotion.
• Content marketing: useful content created to attract and serve an audience.
• Email marketing: communication with subscribers, leads, or customers by email.
• Affiliate marketing: promotion under an agreement that may pay commissions for defined results.
• Influencer marketing: promotion involving creators or people with a relevant audience.

Retargeting, Remarketing, and Lookalike Audiences

Retargeting and remarketing generally involve reaching people who previously interacted with a business. Exact usage varies by platform. Lookalike audiences use a source group to help identify similar potential users. Available tools and restrictions can change.

Cold, Warm, and Hot Audiences

These informal labels describe relationship or intent. Cold audiences have little prior relationship, warm audiences have some familiarity or interaction, and hot audiences show stronger purchase intent. Define these groups using observable behavior rather than assuming awareness equals readiness to buy.

12. Email Marketing Terminology

Open Rate

A common open-rate calculation is unique recorded openers divided by delivered messages, multiplied by 100. Privacy features, automatic image loading, and blocked tracking can make recorded opens differ from actual reading.

Click Rate and Email CTR

A common calculation is unique recipients with recorded clicks divided by delivered messages, multiplied by 100. Some tools use different populations or total clicks, so check the definition. Automated security scanning can also affect click reports.

CTOR — Click-to-Open Rate

CTOR = Unique recorded clickers ÷ Unique recorded openers × 100.

This compares clicks with recorded opens. Inaccurate open tracking also affects CTOR.

Email Conversion Rate

Email conversion rate measures a defined outcome against a chosen population, such as delivered recipients or visitors from the message. Specify the action, denominator, and attribution window.

Email Bounces

An email bounce is a reported delivery failure. Hard bounces generally indicate permanent failures, while soft bounces generally indicate temporary problems. Handling varies by provider.

Unsubscribe Rate and Spam Complaint Rate

These measure recorded unsubscribes and complaints against the provider’s defined message population. Report the denominator and use them to evaluate relevance, expectations, and sending practices.

Delivery, Deliverability, and Sender Reputation

Delivery generally means a message was accepted by a receiving system; acceptance does not prove inbox placement. Deliverability concerns successful placement of legitimate messages in the intended recipient experience.

Sender reputation reflects signals associated with the sending domain, infrastructure, and behavior. Authentication, complaints, recipient engagement, and sending practices can influence message treatment.

List Growth, Opt-In, and Double Opt-In

List growth tracks additions and removals over a period. Opt-in records a subscriber’s agreement to receive the specified communications. Double opt-in adds a confirmation step, commonly through email. Keep account notifications and marketing subscription choices clearly distinguished.

Segmentation, Automation, and Campaign Types

Segmentation groups subscribers by relevant characteristics or behavior. Automation sends messages when configured conditions occur. A drip campaign is a scheduled or triggered sequence; a broadcast sends a message to a selected group; a newsletter is a recurring email publication.

13. Startup and Online Business Terminology

MVP and Proof of Concept

A minimum viable product (MVP) is a limited version of an offer used to test important customer assumptions while delivering its intended core value. A proof of concept (POC) tests whether an idea or technical approach is feasible. Technical feasibility alone does not establish customer demand.

B2B, B2C, and DTC

• B2B — Business to business: selling to organizations.
• B2C — Business to consumer: selling to individual consumers.
• DTC / D2C — Direct to consumer: selling directly to consumers rather than primarily through resellers.

SaaS, Freemium, and Subscriptions

Software as a service (SaaS) delivers software as an ongoing hosted service, often through subscriptions. Freemium provides a free tier alongside paid functionality or capacity. A subscription is a recurring payment arrangement for continuing access or delivery.

Marketplaces, Affiliates, and Commissions

A marketplace connects buyers and sellers. An affiliate promotes an offer under an agreed arrangement. A commission is compensation tied to a specified transaction or result, often a percentage or fixed amount.

Scalability and Product-Market Fit

Scalability describes the ability to handle growth without costs and complexity increasing proportionally. Product-market fit describes an offer satisfying meaningful demand in a target market. A few initial purchases do not establish durable product-market fit.

Bootstrapping and Investment

Bootstrapping uses founders’ resources and internally generated funds rather than relying heavily on external investment. Venture capital typically invests in businesses with substantial growth potential. Angel investors invest their own funds, often at an early stage. Seed funding supports early development and validation.

Pivots and Unit Economics

A pivot is a meaningful strategic change informed by evidence. Unit economics examines revenue and costs per transaction, product, customer, or other unit. State the costs included; increasing sales volume can worsen losses when contribution per unit remains negative.

TAM, SAM, and SOM

• TAM — Total addressable market: the total market opportunity under stated assumptions.
• SAM — Serviceable available market: the portion the business can serve with its offering and reach.
• SOM — Serviceable obtainable market: the portion it could realistically capture under defined conditions and timeframes.

These are estimates requiring evidence, rather than automatic sales forecasts.

14. Vanity Metrics and Business Outcomes

A metric becomes misleading when used as evidence of an outcome it does not measure. Followers, views, and impressions can support an awareness objective, but they do not independently establish sales or profitability.

Revenue, qualified leads, conversions, CAC, LTV, and retention also require context. High revenue can coexist with losses. Strong ROAS on a small sample may not persist at higher spend. Low CAC offers little benefit if the customers are unprofitable or quickly leave.

Select metrics that connect to the objective and examine both the amount of evidence and the financial outcome.

15. Worked Example: From Impressions to Profit

Consider a hypothetical retailer’s campaign. These figures are illustrative and are not Wares Point’s actual results:

• Advertising spend: $1,000.
• Impressions: 100,000.
• Link clicks: 2,000.
• Attributed purchases: 100 orders.
• Revenue attributed to those orders: $5,000, after applicable discounts and refunds.

Campaign Metrics

• CPM: $1,000 ÷ 100,000 × 1,000 = $10.
• Link CTR: 2,000 ÷ 100,000 × 100 = 2%.
• Cost per link click: $1,000 ÷ 2,000 = $0.50.
• Purchases per click: 100 ÷ 2,000 × 100 = 5% for this simplified example. This is not necessarily the website’s session conversion rate.
• Cost per purchase: $1,000 ÷ 100 = $10. This does not establish CAC without new-customer counts and other acquisition costs.
• AOV: $5,000 ÷ 100 = $50.
• ROAS: $5,000 ÷ $1,000 = 5×.

Financial Outcome

Suppose the sold products have $2,500 in COGS and a further $800 in payment fees, fulfillment, shipping subsidies, and allocated operating expenses. Assume those amounts do not overlap and the revenue already reflects refunds.

• Revenue: $5,000.
• Less COGS: $2,500.
• Gross profit: $2,500.
• Less advertising: $1,000.
• Less other stated expenses: $800.
• Remaining after the stated costs: $700.

The $700 is not automatically final net profit or cash available to withdraw. Any excluded expenses, taxes, and payment timing still matter. The 5× ROAS describes advertising-attributed revenue efficiency, while the cost calculation describes the remaining financial result.

16. How the Numbers Connect

1. Impressions and reach describe recorded exposure.
2. CTR and CPC describe click response and its cost.
3. Conversion rates and CPA describe defined outcomes and their acquisition cost.
4. AOV and ROAS connect order revenue with advertising expenditure.
5. CAC, retention, and LTV help evaluate customer relationships over time.
6. Margins, expenses, profit, and cash flow show whether the business can sustain those outcomes.

These are connected questions, not a universal linear journey. A customer may return through several channels or purchase without clicking an advertisement. Use business transaction records alongside platform reports to assess what actually happened.

Evaluate Results Against Your Business Goals

Before deciding whether a number is good, establish what it measures, which period it covers, how it was calculated, and which outcome the business needs.

• For CTR, examine the click definition and what visitors did afterward.
• For CPC, consider traffic quality and conversion outcomes.
• For ROAS, examine margins, refunds, attribution, and all relevant costs.
• For CAC, examine new-customer quality, retention, and supported lifetime contribution.

The purpose of business terminology is to support informed action. Compare related measures, verify the underlying records, and use the results to decide what to continue, improve, or stop.
