The words behind AI search, explained without jargon: how assistants find and cite sources, how visibility is measured, and what you can change on your own site. Every term comes with why it matters for your brand.
The one idea everything else here builds on.

MeasurementAI CitationsWhich pages the assistants lean on, and why that matters.
Content & structured dataGenerative Engine Optimization (GEO)What people mean when they talk about optimizing for AI answers.
The source links an AI assistant shows alongside its answer.
Why it matters. A citation tells you which page the assistant leaned on. Open it and check which sentence it supports before counting it as a win.
Full definition Read: AI citation trackingSoftware that fetches web pages on behalf of an AI company, for search, model training or another stated purpose.
Why it matters. Different AI crawlers do different jobs, so blocking one does not block them all. Review each by name in robots.txt.
Full definitionGoogle’s AI-generated summaries that appear above some search results, often with source links.
Why it matters. They appear for some queries and not others, so track the specific questions your buyers search rather than assuming coverage.
Full definitionWhether, and how, your brand or pages appear in AI answers to the questions you track.
Why it matters. Visibility has parts: being mentioned, being recommended and being cited are different signals and should be reported separately.
Full definition Read: What is AI search visibility?Your brand’s share of mentions compared with a defined set of competitors, across the answers you sampled.
Why it matters. The number only means something alongside its rules: which competitors, which questions, which assistants and which period.
Full definition Read: AI share of voiceA single number that combines several signals, such as mention rate, citation rate, position and sentiment.
Why it matters. Useful for spotting a trend, but always check the parts underneath. Two tools can give different scores for the same brand.
Full definitionStructuring content so AI assistants and answer boxes can pull a clear, direct answer from it.
Why it matters. Most of it is good writing: answer the question early, keep claims specific and make the page easy to parse.
Full definition Read: AEO vs SEOAutomated requests to your website from crawlers, monitoring services, scrapers and other software.
Why it matters. Separating AI crawlers from the rest of your bot traffic shows which assistants are actually reading your pages.
Full definitionAny time an answer names your company or product, with or without a link.
Why it matters. A mention can be positive, neutral or negative. Read the sentence it sits in, not just the count.
Full definition Read: AI mention trackingThe web search experience inside ChatGPT, which can show source links with its answers.
Why it matters. When it cites sources, those links show you which pages shaped the answer about your category.
Full definitionHow easily bots can reach, fetch and read the content on your site.
Why it matters. If a crawler cannot read a page, no amount of content work on that page will help it appear in answers.
Full definitionAI modes that browse many sources over several minutes and write a long report.
Why it matters. Buyers use these for considered purchases, so they are worth checking for high-value B2B questions.
Full definitionA third-party score that estimates how strong a website is in search.
Why it matters. It is a vendor metric, not a Google or AI ranking factor. Use it for comparison, not as a target.
Experience, expertise, authoritativeness and trustworthiness: a framework from Google’s search quality rater guidelines.
Why it matters. It describes what reviewers look for. Show real experience, named authors and sources you can back up.

Why it matters. The marked-up answers must match what visitors can read on the page. Eligibility for rich results is limited and can change.
Full definitionThe extracted answer box that sits at the top of some Google results.
Why it matters. It rewards the same habits as AI answers: a clear question, a direct answer and a well-structured page.
Full definitionWork aimed at improving how a brand or source appears in AI-generated answers.
Why it matters. GEO overlaps heavily with good SEO and content work. It is a goal, not a single ranking system or certification.
Full definition Read: What is GEO?OpenAI’s crawler for collecting content that may be used to train its models.
Why it matters. It is separate from OAI-SearchBot. Blocking GPTBot is a training decision, not a ChatGPT Search decision.
Full definitionLinking a model’s answer to sources it retrieved at the moment of answering.
Why it matters. Grounded answers are where citations come from, and the reason fresh, accurate pages can show up in answers.
Full definitionWhen an AI model states something false with confidence.
Why it matters. This can include wrong prices, features or claims about your brand. Catching these early is a key reason to monitor answers.
Full definitionContent that serves a real reader’s purpose with accurate explanations, useful evidence and the right level of detail.
Why it matters. Length alone does not make a page useful. Ask whether it answers the question better than what already exists.
Full definitionStoring and organizing pages so a search system can find and return them.
Why it matters. Being crawled does not guarantee being indexed, and being indexed does not guarantee being shown.
Full definitionThe new information a page adds beyond what a reader could already find elsewhere.
Why it matters. Original data, first-hand testing and specific examples give assistants a reason to use your page over a near-copy.
Full definitionBuilding or changing page content with code that runs in the browser.
Why it matters. Some crawlers do not run JavaScript. If key content only appears after scripts run, check that bots can see it.
Full definitionA format for adding schema.org structured data to a page as a block of code.
Why it matters. It is the format Google recommends for structured data, and keeps markup separate from the visible page.
Full definitionThe point after which a model’s training data stops.
Why it matters. Anything after the cutoff has to come from live retrieval. Even before it, the model may not know every fact.
Full definitionA structured database of entities and how they relate, used by search engines and AI systems.
Why it matters. Clear, consistent facts about your brand make it easier to be recognized as the right entity.
Full definitionThe type of AI model behind assistants like ChatGPT, Gemini and Claude, trained on large amounts of text.
Why it matters. When buyers ask these assistants for recommendations, the answer becomes part of how they discover brands.
Full definitionA proposed Markdown file at your domain root that points AI tools to your most useful pages.
Why it matters. Support varies and it is not a ranking signal. It is not a replacement for robots.txt or for indexing rules.
Full definition Read: Does llms.txt help?The short HTML summary of a page, often shown under the title in search results.
Why it matters. It rarely affects rankings, but it shapes whether people click and gives machines a quick summary of the page.
Search that works across text, images, voice and video.
Why it matters. Assistants can increasingly read images and video, so product images and captions can matter too.
The field of computing that reads, interprets and generates human language.
Why it matters. It is how systems work out what your content means, not just which words it contains.
Full definitionA directive asking search engines not to include a page in their index.
Why it matters. The crawler must be able to fetch the page to see the directive, so do not also block it in robots.txt.
Full definitionOpenAI’s crawler for its search features, including ChatGPT Search.
Why it matters. Review it separately from GPTBot. Blocking it can limit how your pages appear in ChatGPT Search results.
Full definitionClicks divided by impressions for your unpaid search results.
Why it matters. Compare the same pages and period. A drop with steady rankings can mean more answers are being given on the results page.
Full definition Read: Rankings stable, traffic downAn AI answer engine that searches the web and usually shows its sources.
Why it matters. Its source links make it one of the easiest places to see which pages are shaping answers in your category.
Full definitionRunning a fixed set of buyer questions through AI assistants on a schedule and recording the answers.
Why it matters. Tracking the same questions over time turns one-off screenshots into trends you can report on.
Full definition Read: Prompt trackingWhen an AI search turns one question into several background searches before writing its answer.
Why it matters. Your page can be pulled in by a sub-question you never targeted, so cover the related questions buyers ask.
Full definitionPassages written to stand on their own, with a clear claim and supporting detail.
Why it matters. Short, self-contained statements are easier for an assistant to lift and cite accurately.
Full definitionA setup where a model first retrieves relevant documents, then writes its answer from them.
Why it matters. It is why live pages can influence answers, and why citations exist at all.
Full definitionEnhanced search listings, such as stars, FAQs or product details, for eligible pages.
Why it matters. Which types are supported, and the rules for each, are set by the search engine and change over time.
Full definitionA file at your domain root that tells well-behaved crawlers which paths they may request.
Why it matters. It controls crawling, not access. It is not a security tool and does not remove pages that are already indexed.
Full definitionStructured data, using the schema.org vocabulary, that describes what a page is about.
Why it matters. It makes facts like prices, products and organization details explicit for machines.
Full definitionSearch that matches by meaning rather than exact keywords.
Why it matters. Pages that clearly answer the underlying question can surface even when the wording differs.
Full definitionDepth and consistency of coverage across a whole subject, not just one page.
Why it matters. A connected set of useful pages on a topic is easier to trust than a single isolated article.
Full definitionThe material a model learned from before release.
Why it matters. It shapes the model’s general knowledge, but it cannot fully explain any single answer.
Full definitionYour brand named in text without a link to your site.
Why it matters. These still count in answers, so track them alongside cited links rather than ignoring them.
Full definitionThe identification string sent with each web request, naming the browser or bot.
Why it matters. Anyone can fake a user-agent. Verify important bots with the operator’s published IP ranges where they are available.
Full definitionNumbers that represent the meaning of text so machines can compare ideas.
Why it matters. They are the maths behind semantic retrieval, which decides which passages are pulled into an answer.
Full definitionSoftware that fetches web pages by following links.
Why it matters. It is the discovery layer for search engines and many AI systems. If it cannot reach a page, the page cannot be used.
Full definitionAn HTTP header that carries robots directives, such as noindex.
Why it matters. It is the way to apply noindex to PDFs, images and other files that are not HTML pages.
Full definitionTopics that can affect health, finances or safety.
Why it matters. Search quality guidelines hold these topics to a higher standard, so sourcing and author credentials matter most here.
A search that ends without a click to any website.
Why it matters. The person may have got their answer on the page. It is one reason traffic can fall while rankings hold.
