An HTTP response that tells browsers and crawlers a URL has moved for good, and the new address should replace it. Use it for migrations, HTTPS, and retired pages that have a real equivalent.
A temporary HTTP response that sends users to another URL while signaling the original address should return. Use it for maintenance, tests, geo detours, or short campaign paths.
An A/B Test is an experiment method that shows two (or more) variants at the same time and compares which performs better using statistical evidence.
Pirate Metrics: Acquisition, Activation, Retention, Referral, Revenue. A five-rung growth frame that stops teams staring at one vanity number.
The moment a new user first gets real value—the “aha”. Signing up is not activation; the first meaningful action is.
Ad Fatigue is a performance problem where the same ad's effectiveness declines from being shown repeatedly to the same audience, causing click-through and conversion rates to drop over time.
The start–end window when ads are scheduled to run—the campaign’s calendar, not the campaign object itself. Pacing, frequency caps, and reporting periods are built on those dates.
One serve of an ad unit onto a screen, with no promise that it was noticed or clicked. CPM and click-through rate both use this raw count as the base.
Ad Rank is the ranking score that determines the position an ad appears in on platforms like Google Ads for a given search, combining bid amount, ad quality, and expected impact.
Showing more than one creative in the same slot, in sequence or by weight. Instead of locking a single image, messages take turns—this is how you fight fatigue and run tests.
The placement where an ad sits, plus the inventory that slot can sell. A fixed unit, run of site, and run of network are not the same product.
The amount actually charged for ads—not the allocated budget, but what the platform billed. Pacing, channel mix, and return are written against this number.
Google’s display network for publishers: it fills on-site slots and pays a share of clicks or impressions. It is not the same product as Google Ad Manager for larger inventory.
Branded play: the game is the ad, or the product is built into play—not a banner stuck on the edge of someone else’s title. The job is to be remembered through play, not a single click.
A performance model where a publisher earns a commission for a tracked sale or lead. The advertiser pays when a result lands.
Alt Text is the HTML attribute that describes an image's content in words, allowing screen readers and search engine crawlers to understand what an image depicts even when they can't "see" it.
The clickable words of a link, telling people and search engines what the destination is about. Internally they guide paths; on backlinks they carry a topical hint.
AOV is an e-commerce metric found by dividing the total revenue from orders in a given period by the number of orders, showing how much customers spend on average per cart.
An Attribution Model is a measurement framework that determines how much credit for a conversion should be assigned to each channel or ad a user interacted with during their purchase journey.
A firm selling to another firm, where decisions usually sit with several people and a long cycle. Leads, content, and sales have to run the same story.
A firm selling to a person who will use the product, with shorter cycles and higher volume. Brand memory and immediate conversion pull on the same budget.
A backlink is a link from another website to your page; it is an important authority and discovery signal for search engines.
How much data a host will transfer in a period: megabytes and gigabytes out, not headcount. A few heavy videos can exhaust a plan faster than a quiet text site.
A goods-or-services swap instead of cash—inventory, content, or a stage traded for product or work. It is not free; an unpriced deal wrecks the books and the ROAS.
Showing ads from what someone did on a site or app—pages viewed, cart events, in-app actions. It is a different layer from age-gender or a broad interest list.
Bid Strategy is the umbrella term for the automated or manual approaches used on ad platforms to select the bidding method best suited to a campaign's goals, such as clicks, conversions, or impressions.
Bottom of Funnel: people who are ready to decide. Proof, objection handling, and a clear call to action concentrate here.
Bounce Rate is the percentage of visitors who view only a single page and leave without further interaction.
Whether the target audience recognizes the brand and recalls it in the right category. It is memory work at the top of the funnel, not a last-click KPI.
The measured gap in recall, preference, or purchase intent between people who saw an ad and a control group that did not. It is a survey-based lift study, not a click or last-click sale.
The work of making a brand distinctive and easy to recall—not just drawing a logo. Name, proof, and repetition pile up so people can attach a job to you.
Breakeven Point is the financial concept describing the sales volume or revenue level at which a business's total revenue exactly equals its total fixed and variable costs — the point of neither profit nor loss.
The software that fetches HTML, CSS, and JavaScript and paints the page—Chrome, Safari, Edge, Firefox. Tracking, login, and speed all differ by browser.
A semi-fictional profile of a target buyer built from research—jobs, blockers, and purchase triggers—not a age-and-gender sticker.
Customer Acquisition Cost: the average cost to win a new customer. If media is the only input, the number looks cheaper than it is.
Acquisition Cost is the total amount a business spends, on average, to win one new customer or conversion.
A Canonical URL is an HTML tag that tells search engines which address should be treated as the "primary" version among multiple pages with identical or very similar content.
Cart Abandonment Rate measures the share of users who add items to their cart on an e-commerce site but leave without completing checkout, out of all users who created a cart.
A write-up of starting point, what you did, and the measured result—not a slogan brochure. In sales and content it carries the ‘this can work for you’ claim with proof.
Churn Rate is the metric that expresses the percentage of customers who stop using a brand's service or product within a given period; it's a critical indicator of sustainable growth in subscription-based businesses.
A tap or press on an ad or link; opening the page and converting are separate events. Click-through rate is this count divided by impressions.
Invalid presses on ads: bots, rivals, or incentivized taps that are not real interest. They inflate billed clicks and poison the algorithm’s learning.
Recording which link was pressed, where, and how often—ad clicks, email links, and on-site buttons are the same job at different doors. If the source is unknown, budget is blind.
Software that separates content from code so editors can ship pages, images, and URLs as HTML. You should not need an FTP login for every glossary update.
Two brands appear together on one product, campaign, or experience. Audiences and trust are shared, so each side needs a clear role or both identities blur.
Cohort Analysis is a method of comparing the behavior of groups of users who engaged with a brand within the same time period or around the same event, such as signup or first purchase, over time.
A Google tags behavior layer that changes what tags do based on analytics and ads consent. When users decline, measurement may be modeled rather than fully cookied.
The articles, videos, guides, and assets a brand publishes in search, email, social, or on-site. The job is to answer a question and earn the next step—not to fill a calendar.
A Content Pillar is the core topic that forms the foundation of a brand's content strategy, covered comprehensively and in depth; smaller, more specific pieces of content are built around this topic.
Paying to appear inside a publisher’s editorial environment. Unlike buying a banner, the piece is meant to be read as content—so the label has to be honest.
The defined action you wanted completed: a purchase, signup, download, or form. Traffic without that count means the campaign flew blind on its results.
Sending conversion and event data from your server to an ad platform instead of relying only on a browser pixel. It fills gaps left by cookie and tracking limits.
Conversion Rate is the percentage of visitors who complete a predefined action relative to all visitors.
A Conversion Window is the setting that defines the maximum time after a user interacts with an ad during which a resulting conversion can still be attributed to that ad.
Writing that moves someone to the next step: headline, promise, proof, and call to action. It is not literary prose for its own sake.
Core Web Vitals is the collective name for three core, user-experience-focused performance metrics Google uses to measure a web page's loading speed, interactivity readiness, and visual stability.
CPA (Cost Per Action) is a pricing and performance model based on completed actions such as a sale or form submission.
Cost per click: what you pay when someone clicks, not when the ad is only shown. The auction and Quality Score — or the platform equivalent — move that price as much as your bid does.
Average cost to get one app install from a campaign. You pay for the download, not the click, which is why acquisition teams treat it as the unit price.
What you pay for one defined lead: a form, trial request, or callback. Cheap clicks still get expensive when those forms are junk that sales cannot use.
CPM (Cost Per Mille) is the cost of 1,000 ad impressions; it is one of the most common media buying units.
What you pay when a platform counts a video as viewed. It is not a click or a complete watch, and the “viewed” threshold changes by network, so compare vendors carefully.
Crawl Budget refers to the amount of resource search engine bots allocate to crawling a website's pages within a given time period; it especially affects how promptly important pages get indexed on large-scale sites.
Customer Relationship Management: the system that stores people, contact history, and next steps for sales and marketing. It is relationship memory, not a spreadsheet dump.
CRO (Conversion Rate Optimization) is the systematic process of testing and improving experiences so existing traffic converts at a higher rate.
One product, channel, or partner promoting another offer you already sell. The point is a second door from trust you have—not a random “buy both” line.
Cross-sell is a sales technique where a complementary product is recommended to a customer while or after they purchase a main item, aiming to increase total order value and customer satisfaction.
The stylesheet language that sets color, type, space, and layout on an HTML page. It decides how the interface looks and how interactions feel in the browser.
The button, link, or line that names the next step you want someone to take. Vague labels like “learn more” may collect clicks and still fail the conversion.
CTR (Click-Through Rate) is the percentage of impressions that result in a click on an ad or link.
The map of touchpoints from first awareness to loyalty. Unlike a single funnel slide, channels and emotions overlap.
The structured store for records: users, orders, content, and subscriptions. In marketing, “the list” is usually a view of this store, not a spreadsheet.
A URL that no longer returns the resource, often as a 404 or a timeout. They collect in menus, emails, and body copy and quietly tax both crawl and trust.
Deliverability is the email marketing concept that describes the rate at which sent emails reach a recipient's actual inbox rather than a spam folder, along with the factors behind that process.
Google’s visual demand campaigns across YouTube, Discover, and Gmail. They create demand; they do not harvest a typed search the way Search does.
Showing ads by age, gender, location, or similar declared or inferred layers. It is only a coarse first cut, not a substitute for interest or behavior.
Banners, native units, and other visual formats on sites and apps. Unlike search text ads, they show up before someone has typed a query into the box.
The name people type and see in the address bar: brand word plus extension. Email, TLS, and canonical URLs hang off it; swapping it on a whim splits every signal.
Domain Authority is a scoring system, ranging from 1 to 100, produced by third-party tools to predict a website's ranking potential in search engines based on its backlink profile and overall authority.
A signup that is not active until the person clicks a confirmation link. It drops fake and mistyped addresses and protects deliverability.
A Drip Campaign is a marketing automation consisting of a series of emails or messages sent automatically at predefined time intervals after a user completes a specific action, such as signing up or purchasing.
Demand-Side Platform: software advertisers use to buy impressions across programmatic exchanges. Bids, audiences, and frequency live here.
The same or near-identical text living at more than one URL. Search engines then have to pick a version, and visibility splits.
Dwell Time is a behavioral metric that captures how long a user spends on a page after clicking through from search results, and whether they then return to the search results.
Dynamic Creative Optimization is an automation technology that automatically combines and tests different image, headline, and copy components to show each user the best-performing ad combination.
A 404 Error is the standard error code a server returns when a user tries to reach a page that no longer exists or has moved; it directly affects user experience and site credibility.
E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) describes the quality signals Google considers when evaluating content: experience, expertise, authority, and trust.
An Editorial Calendar is an organizational tool that plans the content a brand will produce for its blog, social media, and other channels by topic, format, publish date, and owner.
Pre-written emails that send on triggers such as signup, cart, or behavior. It is a system, not a one-off newsletter blast.
Email CTR is the metric that shows the share of recipients who clicked a link within an email campaign, relative to the total number of emails sent or opened.
Sending news, offers, or teaching through a permissioned list you own. It is not a rented blast; it stands on delivery, relevance, and an easy way out.
Engagement is a broad metric that captures the total of a user's active interactions with a brand's content — likes, comments, shares, clicks, and similar actions — and is used to evaluate content performance.
Engagement Rate measures interactions such as likes, comments, and shares as a percentage of a post's total reach or impressions.
Event Tracking is the process of recording specific actions users take on a website or app, such as button clicks, form submissions, or video views, individually and sending them to analytics tools.
Evergreen Content refers to content that stays relevant and valuable long after its publish date, not tied to seasonal or momentary trends; it's known for consistently generating organic traffic.
A link from your page to a different hostname. Use it to cite a source or send someone deeper—not as a ranking trick or a farm of outbound URLs that add noise.
A Featured Snippet is a highlighted content box that appears at the very top of Google's search results, above the organic listings, providing a direct short answer to a user's question.
Data you collect from your own site, app, or email list in a direct relationship. As third-party cookies weaken, it becomes the backbone of media and measurement.
An ad that holds a reserved site slot for the campaign, with no rotation against other advertisers. The publisher sells that position exclusively; delivery is predictable, and the rate is usually higher than shared inventory.
A creative that overlays or sticks to the page instead of sitting in the grid. It can raise viewability; if it cannot be closed, it taxes UX and the brand.
Frequency is a performance metric that expresses how many times, on average, a single user has seen the same ad within a given time period.
Frequency capping is a campaign setting that limits how many times the same person can be shown the same ad within a set period, to prevent ad fatigue.
An older protocol for moving files between a computer and a server. Themes and backups still travel this way; classic FTP can send passwords in the clear.
A Funnel is a marketing model that visualizes the stages a potential customer moves through from first encountering a brand to making a purchase, and is used to analyze user drop-off at each stage.
Google Analytics 4: an event-based measurement model for sites and apps. Report logic is not a 1:1 copy of Universal Analytics.
Gated Content is restricted-access content that requires a user to fill out a form or share contact information before they can access it, offered in exchange for that data.
Gross Merchandise Value: the gross transaction volume of a marketplace or shop before commissions, returns, and costs. It is scale, not profit.
Goal Completion is an analytics term for when a user completes a predefined action on a website, such as a purchase, form fill, or signup; it's a core measure of campaign success.
A Google feed that shows content from interests, not from a typed query. News and fresh guides can appear here as a discovery channel besides search.
A discipline of fast experiments across product and marketing to find growth. It is systematic testing, not a bag of tricks.
Google’s container for shipping tags without a code deploy every time. Analytics, pixels, and conversion events should live here under versioned releases.
Hashtag Strategy is a planned content approach that tags social media posts with the right hashtags to increase their discoverability and connect them to a relevant topic, community, or campaign.
A visual of click, scroll, or movement density on a page. It shows what people notice and what they ignore.
Pages written for people first, that actually answer the question. Padded, repetitive, or search-engine-only text sits outside this bar.
Copy shown to a crawler or scraper but hidden from a person on the page. Keyword cloaking is a spam risk; it is not the same as a screen-reader label.
The folder on a hosting account that the web server treats as the site’s public root—often named public_html, www, or htdocs. Files dropped in the wrong folder never appear at the domain.
The service that keeps a site’s files, database, and mail on a machine reachable from the internet. A domain does nothing until DNS points it at that server.
Annotations that tell search engines which language or region version of a page to show. TR and EN URLs must point to each other consistently.
The markup a browser uses to build a page’s structure: headings, paragraphs, links, and forms. CSS paints it and JavaScript makes it interactive; markup itself is not a programming language.
An impression is a single instance of an online ad being displayed to a user.
Impression Share is a metric that shows, as a percentage, how many impressions an ad actually received out of the total impressions it was eligible for.
Links on other websites that point to your pages—the same idea as backlinks. Links between your own URLs are internal links and do not count as inbound.
Attracting people with useful content, guides, and email instead of interrupting them with ads they did not ask for. You can still buy traffic; trust accrues when the first touch helps.
The step after crawling when a search engine stores a page and may show it for queries. Being crawled is not enough if the page never enters the index.
Influencer Marketing is a marketing method that partners with people who hold trust and influence over a specific social media audience to promote a brand's product or service to their followers.
Showing ads from interest categories a person declared or a platform inferred from reading and app use. It is broader than retargeting, which keys off a visit to your own site.
An internal link connects one page on your website to another page on the same domain, helping both users and search engines navigate and understand your site's structure.
Inventory Turnover is a financial-operational metric that shows how many times a business's inventory is sold and replenished within a given period.
Several URLs on the same site competing for the same query, splitting clicks and authority so none of them become the clear result.
How often a target phrase appears relative to the rest of the page. There is no magic percentage that ranks you; stuffing reads as spam and can hurt visibility.
Your URL’s position in the search results for a given query; first place and page ten can share a keyword and still earn very different clicks. Rank belongs to a URL–query pair, not the whole domain.
A KPI (Key Performance Indicator) is a specific, measurable metric used to track progress toward a defined business or campaign goal.
The first page a visitor hits after an ad, email, or search click—built for one job. Unlike a homepage, it trades navigation clutter for a promise, proof, and a single call to action.
A person who is not a customer yet but left enough contact—and permission—to start a conversation. Traffic is not a lead; a form, trial, or chat capture is.
A Lead Magnet is a marketing incentive — a free, valuable piece of content or tool — offered in exchange for a potential customer providing their contact information, usually an email address.
Moving a not-ready lead toward a decision with relevant content and timed contact. It is a value sequence, not one “buy now” email.
How long a page takes to become usable in the browser, measured in milliseconds. A slow first paint raises bounce and wastes both ad clicks and organic visits.
A Long-tail Keyword is typically a keyword phrase of three or more words with low search volume but very clear intent, making it effective at attracting traffic with high conversion potential.
A Lookalike Audience is a targeting method that uses data from existing customers or followers, along with a platform's machine learning algorithms, to find new potential users with similar behaviors.
LTV is the estimated total revenue a customer will generate for a company over the course of their relationship with the brand; it's a core metric for evaluating long-term marketing return.
Lifetime value divided by customer acquisition cost. It summarizes how many times a customer covers what it cost to win them.
The Google Ads rule that decides which search queries a keyword can trigger: exact, phrase, or broad. It trades control for reach.
Marketing Efficiency Ratio: revenue over a period divided by total marketing spend. It shows whole-marketing efficiency when platform ROAS is inflated.
The HTML snippet that often appears under the title in search results. It does not rank the page by itself; it earns the click when it matches the query and the promise on the page.
Middle of Funnel: people who accepted the problem and are comparing approaches. Guides, examples, and email sequences build trust here.
An experiment that changes several elements at once (headline, image, CTA) and measures combinations. It needs more traffic than a simple A/B test.
Paid placements that match the look of the surrounding feed—sponsored posts, recommended articles, in-stream cards. They should still be labeled as ads.
A Negative Keyword is a term added to a search network campaign to specify which searches an ad should NOT appear for, preventing irrelevant impressions and wasted spend.
A Nofollow Link is an HTML attribute added to a link that tells search engines not to pass authority, or link equity, through that link.
A North Star Metric is the single, top-priority performance indicator that best reflects a company's long-term success and the core value it delivers to customers.
Ranking work that happens off your HTML: links, mentions, and brand search on other sites. Title tags stay on-page; a vote from another domain is off-page.
The ranking and click work you do in a page’s own code and copy: title, structure, internal links, speed, and intent match. A vote from another site is off-page, not this.
The welcome path that helps a new user understand the product and reach first value. It is a road to activation, not a pile of tutorial slides.
Open Rate is a core email marketing metric that shows the percentage of recipients who opened a sent email campaign.
Software whose source you can inspect, use, and change under a published license. It is not required to be free of charge; the point is that the code is not a locked box.
Organic Reach is the number of unique users a social media post reaches through a platform's natural distribution algorithm, without any ad spend.
Organic Traffic is the flow of visitors that reaches a website through natural search engine rankings rather than paid ads, and it's a key indicator of sustainable digital marketing growth.
A URL with no internal links pointing to it. Even if it sits in a sitemap, discovery and authority flow stay weak.
A Page Impression is a single instance of a webpage being loaded or viewed by a user, regardless of who that user is.
How many months until a customer’s contribution recovers CAC. It is a cash view, not just an LTV:CAC ratio.
A Google Ads campaign type that bids across Search, Display, YouTube, Discover, Gmail, and Maps from one goal and one asset group. You give signals; the system places ads.
Changing content, offer, or message by person, segment, or context. Printing a first name is not personalization if the promise is still generic.
A Pixel is a small piece of code placed on a website that sends user behavior data, such as page views and purchases, to an ad platform for measurement and optimization.
PPC (Pay-Per-Click) is a paid advertising model where you pay only when someone clicks your ad; it underpins Google Ads and many social ad platforms.
Profit Margin is a core financial performance indicator that shows the percentage of a business's total revenue that becomes actual profit, revealing how much of sales converts into real earnings.
Buying ad inventory through software and auctions instead of one-off human insertions. DSPs, SSPs, and exchanges sit in that chain.
The party that owns the content and the ad inventory: a site, app, or show. Advertisers buy the impressions; this side sells the space and the audience.
Reach is a core visibility metric that counts the number of unique users who saw a piece of content or an ad at least once within a given period.
A visit produced by an actual person, not a bot, crawler, or fake click. Raw hit counts skip that split, even though paid media budgets are meant for humans.
Selling a single impression in an auction that finishes in milliseconds as the page loads. The price is not a preprinted package; the bid follows that user and context.
Responding to a live news story, game, or social conversation with content or ads while the window is still open. Speed helps, but an off-brand joke or the wrong context can turn a share into a backlash.
An HTTP response that sends browsers and crawlers from one URL to another; permanent (301) and temporary (302/307) codes do different jobs. Broken pages, moved content, and short campaign paths all use this mechanism.
A growth mechanic that rewards existing users for bringing new customers. Unlike paid media, it transfers trust.
Remarketing re-engages people who previously visited your site by showing them tailored ads based on their interest or on-site behavior.
Repeat Purchase Rate measures the share of customers who have previously purchased from a brand at least once and go on to make another purchase within a given period.
Retargeting shows ads on other websites to users who previously visited your site, typically using a tracking cookie to re-engage them.
The share of users who come back after a given time. It carries repeat behavior and habit, not a one-off sale.
Someone who had at least one prior session and is recognized again—usually via a cookie. First-timers are new; returners open the site a second time or later.
Money from a sale or another defined value event, shown as currency in analytics and ads. Traffic and leads can precede it, but they are not a substitute.
ROAS (Return on Ad Spend) is the revenue generated for every unit of advertising spend; it is used to measure profitability in performance marketing.
Robots.txt is a simple text file placed in a website's root directory that tells search engine bots which parts of the site they should and shouldn't crawl.
Return on investment: (revenue minus cost) divided by cost. It says whether the spend paid back, in a unit you can compare across channels — if the revenue and cost definitions stay honest.
Ads that run across a network’s inventory without locking to a specific page: you skip site picks and the network fills what it can. CPM usually drops, and so does topical fit.
Ads that rotate across one site’s inventory without locking to a section or URL. The buy is wider than a homepage sponsorship and tighter than a network-wide run.
A colloquial SEO label for why new sites often take time to rank — not an official Google switch. Search has no documented sandbox button; new domains still need crawl, content, and trust to accumulate.
Machine-readable labels that explain a page’s content to search engines. The right type can unlock richer result layouts when the page actually contains that information.
The purpose behind a query: learn, compare, navigate, or buy. Pages and ads rank and convert when they match that purpose, not just the keywords.
Segmentation is the approach of dividing a target audience into smaller, more homogeneous groups based on shared demographic, behavioral, or interest-based traits.
Marketing for visibility in search results — the umbrella can include SEO, but most teams mean paid search. Budget, bids, and Quality Score run independently from organic ranking work.
SEO (Search Engine Optimization) is the set of technical and content practices that help a website rank more visibly in organic search results.
SERP (Search Engine Results Page) is the page of results a search engine shows after a user enters a query.
The bundle of interactions a person has on a site within a time window—page views, clicks, events—usually ending after 30 minutes of inactivity. It is a core analytics unit for reading behaviour.
A brand’s share of category visibility in ads or conversation. It is not the same as share of spend; it is share of being seen.
Search ads that show product image, price, and store name from a product feed. Feed quality usually matters more than bid tweaks.
An XML sitemap is a file listing a site's URLs that helps search engines discover and crawl pages more efficiently, especially on large or complex sites.
SKU is the stock-tracking code a business uses to uniquely identify each product variation, such as color, size, or model, in its inventory.
Google Ads auction-time bidding that chases a conversion or conversion-value goal. tCPA, tROAS, and Maximize conversions sit in this family.
The protocol that hands email from one server to another; newsletters and transactional mail leave through this layer. Bad authentication or a blocklist can tank inbox placement without a visible send failure.
Social Listening is the process of systematically monitoring and analyzing how a brand, its products, or its industry are being discussed across social media and the internet to extract insights.
Other people’s choices used as a trust signal: reviews, counts, logos, case notes, and user content.
The certificate layer that encrypts traffic between browser and server; in practice you see TLS and HTTPS. The padlock is a trust cue, and HTTPS is a light ranking signal as well.
Supply-Side Platform: software publishers use to offer inventory to programmatic demand and try to maximize yield.
A snapshot that lines up strengths, weaknesses, opportunities, and threats. Internal factors are yours to change; external ones come from the market and rivals — mixing the two blurs the plan.
Limiting who sees an ad by demographics, interests, behavior, or a custom audience list. Tight targeting cuts waste; over-narrowing kills learning and scale.
A cookie set by a domain other than the site you are visiting. For years it powered retargeting and cross-site tracking; browsers have been restricting it.
The primary HTML title for a page: browser tab, SERP headline, and a core on-page ranking cue. A vague or duplicated title wastes both clicks and the strongest keyword placement you have.
Top of Funnel: content and ads for people who just noticed a problem. The job is demand and trust, not an immediate sale.
A Topic Cluster is an SEO-focused content structure made up of a group of content pieces that cover different subtopics of a main pillar topic, all internally linked back to that pillar page.
UGC is the umbrella term for photos, videos, comments, and reviews created voluntarily by customers or followers rather than by brand employees.
A person or device identity counted once in the reporting window; that same identity can still generate many visits. Clearing cookies or switching phones can split one human into two records.
How many distinct visitor identities reached the site in a period, with repeats folded together. It measures reach, not session volume; device and browser splits can inflate the number.
Unsubscribe Rate is the metric that shows the share of recipients who unsubscribed from a list after receiving an email campaign, relative to the total number of recipients it was sent to.
Upsell is a sales strategy that aims to increase order value by directing a customer toward a higher-priced, more comprehensive, or higher-quality version of the product they were considering.
The full address a browser opens: scheme, host, and path in one string. People share it, crawlers fetch it, and analytics treat it as a page — canonical choice should pin signals to one address.
Whether someone can finish a job on the site with little friction — separate from looking polished. Buried menus, messy forms, or tiny tap targets still kill conversion.
The whole journey a person feels on the site: speed, clarity, trust, and finishing the job. The interface is the visible layer; copy, performance, and support sit inside the experience too.
The buttons, forms, menus, and layout a person actually touches on screen. It is not the whole experience: interface is how it looks and works; experience is how the journey feels.
Unique Selling Proposition: a concrete reason to choose you that rivals cannot copy easily. It is a selection reason, not slogan decoration.
UTM parameters are tags added to a URL so analytics can distinguish campaign traffic by source, medium, and content.
UTM Source/Medium is the combination of UTM parameters used to tag which source, such as Google or Instagram, and which medium type, such as organic, paid, or email, a website's traffic came from.
Who you help, which problem you solve, and what result they get. It is the broader page-level promise sitting next to a USP.
A video or ad counted as watched or seen once it clears the platform’s threshold — not the same as an impression. YouTube, Meta, and programmatic clocks differ, so do not treat the totals as identical.
A conversion credited after an ad impression with no click, inside a set window. Display and video campaigns lean on this claim more than search does.
A session-like stay on the site; several pageviews can sit inside one visit. The same person can log several visits in a day while still counting as one unique user.
How long a visit or session lasts; used to judge engagement and content depth. Single-page bounces can show near-zero time, so read the metric with that caveat.
