CAC— Customer Acquisition Cost
Paid MediaThe total cost to acquire one new paying customer, including ad spend, salaries, and tools divided by the number of new customers in a period. Lowering CAC while maintaining quality is a core lever of profitable growth.
A prompt — button, link, or phrase — that directs users to take a specific next step. Strong CTAs are specific, benefit-focused, and reduce friction. They're the most-tested element in conversion rate optimisation.
The spending limit assigned to a campaign over a day or longer period, affecting pacing, reach, and learning speed.
An HTML tag that tells search engines which version of a page should be treated as the primary URL when similar or duplicate versions exist. Canonicals help consolidate ranking signals and reduce duplication issues.
The event where a user adds products to cart but leaves before completing checkout.
The degree to which target buyers understand a category exists and can recognize when they need it.
A real-world trigger that causes buyers to enter a category and start looking for solutions.
Category page SEO is the optimization of pages that group products or services under a commercial theme. These pages are often high-value because they can rank for broad buyer-intent searches at scale.
A crypto exchange operated by a company that manages custody, order books, and user accounts. CEX funnels are often measured with signup, KYC completion, deposit, and funded-account metrics.
A rules-based way of organizing traffic into broader channels such as organic, paid, referral, or email.
The distribution of budget and effort across channels such as SEO, paid search, paid social, email, and partnerships. A healthy channel mix reduces overdependence on any single source of growth.
The rate at which users begin a checkout flow but fail to complete purchase. Common causes include unexpected costs, slow forms, weak trust, or payment friction.
Any barrier in the purchase flow that makes it harder for users to complete a transaction, such as hidden costs, forced account creation, confusing fields, or weak payment trust.
A situation where too many options make decisions harder and lower conversion likelihood.
The percentage of customers who cancel or do not renew within a given period. High churn erodes MRR growth and increases CAC payback period, making retention optimisation as important as acquisition for sustainable growth.
The amount of monthly recurring revenue lost from fully canceled customers.
The amount of a token currently available in the market and not locked or unavailable.
Citation building is the process of creating or correcting business listings across directories and local platforms. It supports local SEO by reinforcing business identity, location accuracy, and trust signals.
A click map is a visual report showing where users click on a page or interface. It helps teams understand which elements attract attention, which are ignored, and where misleading design patterns may be creating friction.
The share of total possible clicks your ads received in the auctions you could have competed in.
Grouping users by a shared characteristic at a specific point in time — typically acquisition date — and tracking their behaviour over subsequent periods to identify retention patterns and LTV by segment. Cohort analysis reveals whether retention is improving or degrading over time and which acquisition channels produce users with higher long-term engagement.
Collection page SEO focuses on improving group-level ecommerce pages that organize related products or offers. These pages often target broader transactional searches and play a key role in site architecture.
A commercial intent keyword is a search term used by people comparing solutions, evaluating providers, or researching a likely purchase. These queries often sit closer to revenue than purely informational searches.
A forward-looking version of MRR adjusted for known upcoming expansion, contraction, or churn.
A side-by-side content block used to help users evaluate plans, options, or products more quickly.
A paid search tactic where advertisers bid on competitor brand terms to capture comparison-stage demand. It can work, but usually requires careful message match and economics.
Short pieces of copy that reduce anxiety near a decision point, such as privacy reassurance, delivery clarity, or cancellation language. Confidence copy often improves form and checkout completion.
The page shown after a successful conversion, often used for reassurance or next-step guidance.
A Google framework that changes how analytics and ad tags behave depending on a user's consent choices. It helps balance privacy compliance with measurement continuity when cookie consent is denied or limited.
A content brief is a planning document that outlines the target keyword set, search intent, structure, key talking points, and conversion angle for a page. Strong briefs improve consistency and reduce weak or generic SEO content.
The decline in rankings, clicks, or usefulness that happens as content becomes outdated or is outperformed.
A qualitative or custom metric used to judge how comprehensively a page covers a topic. Greater content depth often improves usefulness and ranking potential.
Content gap analysis identifies topics, queries, or formats your site is missing compared with competitors or search demand. It helps prioritize pages that can improve topical coverage and organic traffic potential.
A central pillar page supported by a cluster of topically related blog posts and landing pages, all interlinked. Content hubs build topical authority, help target competitive head terms, and distribute internal link equity across the cluster.
Content pruning is the act of updating, consolidating, redirecting, or removing low-value pages so a site becomes clearer and stronger overall. It is often used to reduce index bloat, eliminate duplication, and improve topical focus.
Recurring revenue lost when existing customers downgrade without fully churning.
The revenue left after variable costs that contributes toward fixed costs and profit.
A server-side method for sending conversion events directly to ad platforms.
An incrementality measurement method that compares users exposed to ads against a control group to estimate the true additional conversions caused by the campaign.
The estimation of missing conversions using statistical methods when direct measurement is incomplete. Conversion modeling helps fill gaps caused by privacy and browser limits.
Conversion path length measures how many touches, visits, or interactions usually happen before a conversion occurs. It helps marketers understand whether a journey is fast and direct or longer and more dependent on multiple channels.
A measure of how valuable or sales-ready a conversion is, not just whether it happened. Improving conversion quality helps paid channels optimise toward revenue instead of noise.
The percentage of visitors or users who complete a desired action. Conversion Rate = (Conversions / Total Visitors) × 100. Even small improvements in conversion rate compound significantly on paid media budgets.
The process of measuring actions that matter to your business — purchases, leads, sign-ups — and sending that data to ad platforms to evaluate performance and power automated bidding strategies like Smart Bidding.
Settings that adjust reported conversion values based on audience, location, or device priorities.
The interface that asks users to accept, reject, or customise tracking consent. Its design and logic affect both compliance and data quality.
The comparison of different headlines, CTAs, and messaging angles to see which wording converts better. Copy testing can improve performance without redesigning a page.
Google's set of page experience metrics: Largest Contentful Paint (LCP) for loading speed, Cumulative Layout Shift (CLS) for visual stability, and Interaction to Next Paint (INP) for responsiveness. These are a confirmed Google ranking factor.
Cornerstone content is one of the main pages a site wants to rank and build authority around. It is usually broader, more complete, and more strategically important than supporting cluster pages.
The acquisition cost required to drive a user to a real activation milestone.
The acquisition cost required to bring in one account that completes an actual deposit or funds a wallet. This metric is often more meaningful than simple signup cost in fintech and crypto.
The total ad spend divided by the number of leads generated in a period. CPL = Total Spend ÷ Leads. It measures efficiency specifically for lead-generation campaigns rather than direct purchase campaigns, and should always be paired with lead quality metrics (SQL rate, close rate) to avoid optimising for cheap, low-quality leads.
CPA— Cost Per Acquisition
Paid MediaThe cost to achieve a specific conversion action such as a purchase, lead, or sign-up. CPA = Total Spend ÷ Conversions. It differs from CAC in that it tracks any conversion event, not only net-new customer acquisition.
The amount you pay each time a user clicks your ad. CPC = Total Ad Spend ÷ Total Clicks. Reducing CPC through better Quality Scores or audience targeting, while maintaining conversion rate, directly improves ROAS.
The average cost to drive one app install through paid advertising. CPI = Total Spend ÷ Total Installs. It is the primary efficiency metric for mobile user acquisition campaigns and varies significantly by platform and category.
The cost per one thousand ad impressions. Common in display and social advertising where brand awareness is the goal. CPM = (Total Spend ÷ Total Impressions) × 1,000.
The percentage of sessions or users that experience the app without a crash.
Crash-free sessions measure the percentage of app sessions that complete without the app crashing. It is a useful health metric because even strong acquisition performance breaks down quickly if the product experience is unstable.
The amount of crawling attention search engines are likely to spend on a site within a period of time. On large sites, weak crawl budget management can slow discovery and re-crawling of important pages.
How many clicks away a page is from core entry points such as the homepage or major navigation.
The practice of investigating crawl errors, bot behavior, server responses, and blocked resources. Crawl diagnostics are a core part of technical SEO maintenance.
A crawl error happens when a search engine crawler cannot successfully access or process a page. Monitoring crawl errors helps catch indexing losses, broken pages, and technical SEO problems before they spread.
The relative importance a site gives different pages for bot discovery through internal links, sitemaps, and architecture. Better crawl priority helps important pages get crawled sooner.
A grouped collection of headlines, descriptions, videos, or images used together in an ad system. Creative asset sets make testing and rotation more structured.
Creative fatigue happens when an audience sees the same ad too often and engagement begins to decline. Rising frequency paired with falling CTR or conversion rate is usually a sign that fresh creative is needed.
The act of replacing or updating ads before fatigue drags performance down.
A coordinated group of ads used together in a mobile acquisition campaign.
A structured process of comparing different ad concepts, hooks, formats, or messages to identify which creative variables improve click-through rate, conversion rate, or cost efficiency.
The sequence of browser steps required to turn HTML, CSS, and JavaScript into pixels on screen. Optimising the critical render path improves perceived speed.
CRO— Conversion Rate Optimisation
CROThe systematic process of increasing the percentage of visitors who take a desired action, using data, UX research, and controlled experiments rather than guesswork. CRO compounds ROAS improvements without increasing ad spend.
A setup that preserves attribution and session continuity when users move between related domains.
A marketing campaign distributing free tokens to wallet addresses meeting specific eligibility criteria — typically based on historical protocol usage, community participation, or holding a specific token. Airdrops simultaneously serve as user acquisition, product distribution, and community building events. Designing eligibility criteria to target genuine users rather than airdrop farmers is critical for post-distribution retention.
CTA friction refers to anything about a call to action that makes users hesitate, such as vague wording, low trust, poor visibility, or a mismatch with user intent. Reducing CTA friction often lifts conversions without requiring more traffic.
The percentage of people who see your ad and click it. CTR = (Clicks ÷ Impressions) × 100. A strong CTR signals ad relevance; a weak CTR suggests misalignment between ad copy and audience intent.
A user-defined attribute in analytics platforms used to capture extra context such as user type, plan tier, content category, or logged-in status for reporting and segmentation.
User-defined attributes in analytics tools used to capture extra context such as plan type, content category, or customer segment. They make reporting far more actionable than default metrics alone.
Numerical values you define in analytics tools to track business-specific data such as margin, scroll percentage, or content score. Custom metrics extend reporting beyond standard platform fields.
A Customer Data Platform centralizes customer data from multiple sources to build unified user profiles that can be used across analytics, advertising, CRM, and personalization tools. A CDP is especially valuable when teams need more reliable first-party data for segmentation and attribution.
Customer exclusion is the practice of removing existing customers from acquisition campaigns so budgets are not wasted on users who have already converted. It is especially important in lead generation, subscription businesses, and remarketing-heavy accounts.
A composite metric used to estimate retention or expansion likelihood for an account.
The full sequence of touchpoints and decisions from awareness through conversion and retention.
A first-party audience list built from known customers for targeting, exclusion, or expansion.
A targeting feature that lets advertisers upload first-party customer data such as email addresses so platforms can match those users and build audiences for search, YouTube, or display campaigns.
A list used to exclude existing customers or low-priority segments from acquisition campaigns. Suppression reduces wasted spend and keeps CAC cleaner.
