Landing Page Design FAQ & Glossary: Every Term Explained
Landing page design has its own vocabulary, and a lot of it gets thrown around loosely — “conversion rate” and “click-through rate” get confused constantly, and terms like “above the fold” get applied to devices where the concept barely still makes sense. This glossary organizes the terms practitioners actually use, grouped by category, with plain-language definitions rather than jargon-on-jargon explanations.
Use it as a reference: if you’re briefing a designer, reviewing an agency proposal, or just trying to make sense of an analytics dashboard, the term you’re looking for is almost certainly grouped below.
Core Landing Page Terms
A landing page is a standalone web page built for one specific purpose — usually to convert a visitor arriving from an ad, email, or search result into a lead or customer — as opposed to a homepage, which serves many purposes for many types of visitors at once. A call-to-action (CTA) is the single instruction the page wants the visitor to follow, typically a button (“Get a Free Quote,” “Start Your Trial”) rather than a passive link.
The hero section is the top portion of the page visible before scrolling — the headline, subheadline, primary image, and CTA that make the first impression. Above the fold refers to content visible without scrolling; the term is inherited from newspaper layout and has gotten fuzzier as screen sizes vary, but it’s still shorthand for “the part almost everyone sees.”
A squeeze page is a minimal landing page with almost no navigation and a single, narrow goal — usually collecting an email address in exchange for something (a discount, a guide). A microsite is a small standalone site, sometimes just a handful of linked pages, built around a single campaign or product rather than the full business.
Traffic and Campaign Terms
Paid traffic refers to visitors arriving from advertising — search ads, social ads, display — while organic traffic refers to visitors arriving from unpaid search results. Landing pages built for paid traffic can be narrower and more single-minded than pages meant to also rank organically, since organic visitors arrive with more varied intent and search context.
UTM parameters are tags added to a URL (like utm_source or utm_campaign) that let analytics tools identify exactly which ad, email, or link sent a visitor to the page — essential for knowing which traffic source actually converts, not just which one sends the most clicks.
Bounce rate measures the percentage of visitors who leave without any further interaction, though on a single-purpose landing page a “bounce” can sometimes be misleading — a visitor who reads the whole page, calls the phone number listed in the header, and never clicks anything else on the page may register as a bounce despite converting. Click-through rate (CTR) measures how often people who see something (an ad, a search result) click it, which is a different metric entirely from conversion rate and shouldn’t be confused with it.
Conversion and Testing Terms
Conversion rate is the percentage of visitors who complete the page’s intended action — a form submission, a call, a purchase. It’s the single most important landing page metric, but only when measured against a clearly defined “conversion” event, which is why setting that definition before launch matters more than most teams realize.
A/B testing (also called split testing) compares two versions of a page — usually with one variable changed — to see which converts better, typically using a tool like VWO, Optimizely, or a platform’s built-in testing feature. Multivariate testing tests multiple variables at once and how they interact, which requires significantly more traffic to reach reliable conclusions than a simple A/B test.
Statistical significance is the threshold at which a test result is unlikely to be due to random chance — running a test and stopping it the moment one version looks ahead, without reaching significance, is one of the most common and costly testing mistakes. A funnel describes the sequence of steps a visitor moves through toward conversion (landing page view, form start, form submission), and funnel analysis identifies exactly where visitors drop off.
Copywriting and Persuasion Terms
A value proposition is the specific, differentiated reason a visitor should choose this offer over alternatives — not a slogan, but a clear statement of benefit. Social proof refers to evidence that other people have used and trusted the product or service — reviews, testimonials, client logos, case studies — and it works by reducing the visitor’s perceived risk.
Objection handling is the practice of directly addressing the specific hesitations a visitor is likely to have (cost, trust, fit) rather than ignoring them and hoping enthusiasm carries the visitor past them. Friction is anything that makes converting harder or slower than necessary — an extra form field, a confusing button label, a slow-loading page — and reducing friction is often more impactful than adding persuasive copy.
Design and UX Terms
A wireframe is a low-fidelity layout sketch — boxes and placeholder text — used to plan page structure before visual design begins. Visual hierarchy is the intentional arrangement of size, color, and position so a visitor’s eye moves through the page in the order that best supports the argument, usually landing on the CTA.
Whitespace (or negative space) is the deliberately empty area around elements that gives them room to be noticed rather than competing with everything else on the page. Mobile-first design means designing for the smallest, most constrained screen first and expanding up to desktop, rather than designing for desktop and shrinking down — a practice that matters because most landing page traffic now arrives on phones.
Accessibility refers to designing so people with disabilities — visual, motor, cognitive — can use the page, including sufficient color contrast, properly labeled form fields, and keyboard-navigable elements. It’s frequently treated as optional polish; it shouldn’t be, both ethically and because accessible pages tend to be clearer pages for everyone.
Technical and Tracking Terms
Page speed is how quickly a page becomes usable, and it directly affects conversion rate — slow pages lose visitors before the persuasive content ever loads. Core Web Vitals are a specific set of Google-measured speed and stability metrics (loading, interactivity, visual stability) that factor into both user experience and search visibility.
A tracking pixel is a small snippet of code that reports back to an ad platform (like Meta or Google) when a specific action happens on the page, enabling both measurement and audience retargeting. A tag manager (most commonly Google Tag Manager) is a tool that lets teams add and manage these tracking snippets without editing the page’s underlying code directly.
Schema markup is structured data added to a page’s code that explicitly tells search engines what the content means — a business’s hours, a product’s price, a review’s rating — rather than leaving those facts for a crawler to infer from plain text.
AI-Search-Era Terms
An AI Overview is the AI-generated summary that now appears above traditional results for many searches, synthesizing information from multiple sources rather than sending the searcher directly to a single page. Answer engine optimization (sometimes called AEO or GEO) refers to the practice of structuring content so AI systems can accurately extract and cite it, which favors clear, specific, factual statements over vague marketing language.
An entity, in this context, is a distinct, identifiable thing — a business, a person, a product — that search and AI systems can recognize and connect facts to across the web. Landing pages that clearly and consistently state entity facts (business name, service area, credentials) help both human visitors and AI systems trust and accurately represent the business.
Frequently Asked Questions
What's the difference between conversion rate and click-through rate?
Click-through rate measures how often people click on something they see, like an ad or search result. Conversion rate measures how often visitors who land on the page actually complete the intended action, like submitting a form. They measure different stages of the same journey and shouldn't be used interchangeably.
What's the difference between a landing page and a homepage?
A landing page is built for one specific purpose and one specific type of visitor, usually arriving from a single traffic source. A homepage serves many purposes for many different visitor types simultaneously and typically includes broader navigation.
What does "above the fold" actually mean today?
It refers to whatever content is visible on a screen before scrolling. The term comes from newspapers, and its meaning has become less precise as screen sizes vary widely across devices, but it's still used as shorthand for the highest-visibility portion of the page.
Is A/B testing worth it for a low-traffic landing page?
Often not in the strict statistical sense — reaching statistical significance requires a meaningful volume of visitors, and low-traffic pages can take a very long time to produce a trustworthy result. Lower-traffic pages usually benefit more from qualitative review (heatmaps, session recordings, direct feedback) than from formal split testing.
Why does schema markup matter for a landing page?
It gives search engines and AI systems explicit, structured facts about the page's content instead of requiring them to infer meaning from plain text, which can improve how accurately and favorably the page is represented in search results and AI-generated summaries.
What is a lead magnet?
A lead magnet is something of value — a guide, a discount, a free consultation — offered in exchange for a visitor's contact information. It's a common mechanism on squeeze pages and lower-funnel landing pages built specifically to generate leads rather than direct purchases.
