Glossary
Content, SEO & Search
AEO / GEO (Answer Engine Optimization / Generative Engine Optimization)
The practice of optimizing content to be surfaced and cited by AI-powered answer engines and generative search tools (such as AI chat assistants and AI-generated search summaries), as distinct from optimizing for traditional ranked search results.
Alt text (image alt text)
A short text description attached to an image in a webpage's HTML, describing what the image shows — displayed if the image fails to load, read aloud by screen readers for accessibility, and used by search engines to understand image content.
Backlink
A link from one website to a page on another website — in SEO terms, a link pointing to your site from an external domain.
Canonical tag
An HTML element that tells search engines which version of a page (among multiple similar or duplicate versions) should be treated as the authoritative one to index and rank.
Content marketing
A marketing approach focused on creating and distributing valuable, relevant content — articles, videos, guides — to attract and retain an audience, rather than directly promoting a product through traditional advertising.
Crawl budget
The number of pages on a website a search engine's automated crawler will visit and index within a given period, which can be a practical constraint for very large websites with many thousands of pages.
Domain authority
A score (developed by SEO tool providers, not by search engines themselves) predicting how well a website is likely to rank in search results, based largely on the quantity and quality of backlinks pointing to it.
Evergreen content
Content designed to stay relevant and valuable over a long period of time, as opposed to content tied to a specific, time-sensitive event or trend.
Featured snippet
A search result format where a search engine displays a direct excerpt or summary from a webpage at the very top of the results page, above the standard list of ranked links, typically in response to a question-style query.
Gated content
Content — typically a guide, report, or template — made available only after a visitor provides information, usually an email address, via a form.
Heatmap
A visual representation of user behavior on a webpage — typically showing where visitors click, how far they scroll, or where their attention concentrates — using color gradients to indicate areas of high and low activity.
Internal linking
The practice of linking from one page on a website to another page on the same website, as distinct from a backlink, which comes from an external site.
Keyword
A word or phrase a person types into a search engine, or that a piece of content is optimized to rank for.
Long-tail keyword
A longer, more specific search phrase, typically with lower search volume but also lower competition and often higher purchase intent than a short, broad "head" keyword.
Meta description
A short block of HTML text describing a webpage's content, not directly visible on the page itself but often displayed as the descriptive snippet beneath a page's title in search engine results.
Organic vs. paid (search/traffic)
"Organic" refers to unpaid traffic or search results — earned through content, SEO, and relevance rather than direct payment. "Paid" refers to traffic or placement obtained by paying an advertising platform.
Pageviews
The total number of times a page was loaded or reloaded in a browser, counted every time it happens, including repeat views by the same visitor within a single session.
Pillar page
A comprehensive, broad page covering an entire topic at a high level, designed to rank for a competitive, high-volume "head" keyword, and structured to link out to multiple related, more specific "cluster" pages that each cover a narrower subtopic in depth.
Referral traffic
Website visits that arrive via a link from another website, as tracked and categorized separately from organic search, direct, paid, or social traffic sources.
SEO (Search Engine Optimization)
The practice of improving a website's visibility in unpaid ("organic") search engine results, through a combination of technical site health, content quality, and external authority signals like backlinks.
SERP (Search Engine Results Page)
The page displayed by a search engine in response to a query, containing organic results, paid ads, and increasingly, AI-generated summaries and other rich features.
Schema markup
Structured data code added to a webpage's HTML that helps search engines understand the content's meaning and context — for example, marking up a recipe's ingredients and cook time, or an article's author and publish date.
Scroll depth
A measure of how far down a page a visitor scrolls, typically tracked as a percentage of total page length or at defined checkpoints (25%, 50%, 75%, 100%).
Sessions
A single, continuous period of activity by one visitor on a website, typically defined as ending after a set period of inactivity (commonly 30 minutes) or at midnight, after which any further activity counts as a new session.
Time on page / Session duration
The average amount of time visitors spend on a specific page (time on page) or across an entire visit (session duration) before navigating away.
Topic cluster
A group of related content pieces — typically several specific articles — all linking back to a central pillar page, organized around one broad topic to signal comprehensive topical coverage to search engines.
Unique visitors
The count of distinct individual people who visited a website within a given period, counted once regardless of how many separate sessions or page views they generated.
