Plain-English Glossary
Every term we use, defined without jargon — and where an analogy makes something clearer than a definition does, you get the analogy too.
What we measure
The numbers on your dashboard, and what each is counting. One thing before the list, because it prevents most misreadings: mention rate counts EVERY answer, while citations, sentiment and competitive position are measured only across the answers where you appeared. Those three describe quality when you show up — not how often you show up.
Visibility Score
One number, 0–100, for how present you are in AI answers.
Built from mentions, citations, sentiment and competitive position, weighted by how many people actually use each engine — ChatGPT 32%, Google AI Overview 30%, Gemini 20%, Claude 10%, Perplexity 8%. A mention on ChatGPT is worth more than one on Perplexity because far more buyers ask it. If a high mention rate sits next to a middling score, that is almost always engine mix: strong on the engines fewest people use.
Mention
An AI answer named your business.
Counted when your business name appears in the answer to a tracked phrase. The share of all answers that named you, and the number to lead with. What it does NOT tell you is position — being named eighth counts exactly the same as being the first recommendation, which is why rank is reported separately.
Citation
An AI answer linked to your website.
Stronger than a mention. A mention means the engine knew your name; a citation means it pointed at your site as the source. It matches on your DOMAIN, never your company name — for a business at example.com it looks for “example.com”, and any page on that domain counts. Naming you and sourcing from you are two entirely separate measurements, which is why the numbers can diverge sharply. Perplexity cites most heavily because it is built to show sources.
Sentiment
How positively you were described when you were named.
It reads the wording of the AI’s own response. Three things it is not: a survey of what your customers or review sites say; a measure of answers that did not mention you (absence is invisibility, never a bad review); or a large sample — on a small scan it may rest on three or four answers. Negative sentiment usually reflects thin, outdated or confused information rather than criticism.
Rank
How early you appeared in the answer.
Reported in bands rather than exact positions. The engines are non-deterministic — the same question asked twice does not return the same answer — so a precise number would imply more certainty than the measurement supports. A few points of movement between scans is normal and means nothing; a consistent direction over several scans means something.
Priority
How much a recommendation is expected to move your visibility.
Impact, not effort and not urgency. Two things are always top because nothing else can work while they hold: AI search crawlers being unable to reach your site, and your pages being ineligible to appear in Google's AI answers. Beyond those it is a judgement, so several recommendations can share the top band — and a high-priority item is often quicker than a low-priority one. Read it alongside the “website update required” note, which tells you who has to do the work rather than how much it matters. Note too that your list is deliberately a MIX rather than every high-priority item at once — some lower-priority actions are quicker, and you can finish those while a slow one is still in progress. That also means a new high-priority item can appear later: the list refills as you complete things, and nothing was being held back from you.
High priority does not mean hard, and low priority does not mean pointless. One is about the size of the gain; the other is about the size of the job.
Who AI Named
The businesses the answers actually put forward, whether or not you track them.
The more trustworthy competitive read, because nobody's list biases it. Competitive position depends on which rivals you chose to track; this reports whoever genuinely appeared.
Competitive position
How often you appear relative to the competitors you track.
100% means you appeared every time a competitor did. Treat it carefully: it depends entirely on which competitors you track, and with few or none tracked it says very little. It is also never offered as something to act on directly — it moves as a consequence of the other measures shifting relative to everyone else.
Read mentions and citations together
This is the most informative thing on your dashboard, and neither number says it alone.
AI knows you and is reading your site. The healthy case.
AI knows you from what it absorbed in training, not from your site today. Stop here — if nothing you publish is being fetched, changing your website cannot change the answer.
You are being read but not recommended. Usually a positioning problem rather than a technical one.
The middle case is the one worth stopping on. Your reputation is fixed in the past and you have no live channel into the present. Almost every content recommendation the product makes is an attempt to open that channel.
How AI engines find you
The part that causes the most confusion, because two completely different systems both end up feeding the same answer.
Search phrase
A question someone asks before they know your business exists.
Not your business name, and not how you describe yourself. The phrases you track decide what your score actually measures.
A phrase whose answer cannot name any business cannot tell you apart from your competitors. “How much does a home theatre cost” names nobody, so it scores zero for everyone.
Crawler (bot)
A program that visits web pages automatically.
Different crawlers do different jobs, and they announce themselves by name so a site owner can allow one and refuse another. OpenAI runs three: OAI-SearchBot for search, GPTBot for training, and ChatGPT-User for live fetches when someone asks a question. Anthropic runs the same three-way split for Claude.

Index
The stored copy of the web an engine searches when you ask it something.
Built in advance by crawlers, on their own schedule. When you ask a question, the engine looks here first — it does not go and read your website on the spot.
Retrieval
The engine looks something up and reads it back to you.
The fast loop, and the only one you can influence this quarter. Publish a change and it can appear within days or weeks, once the crawler returns. This is what indextr measures, deliberately, because it reproduces what a real person gets today.
A librarian with a photocopier. It walks the web copying pages into a filing cabinet. When you ask a question it finds the right page, pulls it out and reads it aloud — which is why you get a citation, and why fixing your page changes the answer next time it is copied.
Training data (parametric knowledge)
What the model absorbed when it was built, and can recall with no search at all.
The slow loop. It changes only when a new model is trained, months or years apart, and nothing you publish this week affects it. You do not get in by being crawled — you get in by being written about, repeatedly, across many sources, over years.
A student reading for a degree. It reads enormous amounts, then answers from memory — but cannot tell you which book a fact came from, which is why there is no citation. Handing it a new book today changes nothing, because it already graduated.
Recrawl
A crawler coming back to see what changed.
The gap between making a change and an engine noticing it. No vendor publishes a schedule, which is why time-to-impact estimates are estimates.
Fixing a broken doorbell tells you the door works. It does not tell you the postman has been.
robots.txt
A file telling crawlers which parts of your site they may visit.
It is a request, honoured by well-behaved crawlers. Worth knowing that blocking is often not done here at all — security services and CDNs frequently block AI crawlers before a request ever reaches your site, and the site owner is never told.
Things on your website
What an AI answer can quote, and what it cannot.
Title tag
The page's name, shown in the browser tab and in search results.
The single highest-weight piece of text on a page. A title reading “Home” wastes it. It should carry the business name and what distinguishes it — what you do, and where. A note on terminology: people often say “meta tags” for the title and description together, and any developer will know what is meant, but strictly the title is its own HTML element and not a meta tag at all. “The title tag and meta description” is the precise phrasing.
Meta description
A one-sentence summary of the page, in the HTML.
Plain text an engine can read and quote, and a genuine meta tag. If you do not write one, engines assemble a summary from whatever text they find, which produces exactly the stitched-together fragments you would expect. About 150 characters; longer gets cut off in search results.
Alt text
A written description of an image, for people who cannot see it.
Also the only part of an image an engine reliably reads. Google states it uses alt text alongside the page's content to understand what an image shows.

Schema markup (structured data)
Machine-readable code declaring facts about a page — and three words people use interchangeably that are not the same thing.
The three terms nest. STRUCTURED DATA is the umbrella — any machine-readable markup describing what a page is about. SCHEMA.ORG is a vocabulary, the shared dictionary of types like LocalBusiness, FAQPage and Review; it is so dominant that people say “schema” when they mean structured data generally. JSON-LD, MICRODATA and RDFa are formats — three ways of writing that vocabulary into a page. Google says it “recommends using JSON-LD for structured data if your site’s setup allows it”, which is a preference among formats for sites that choose to add it, not a statement that you need any.
indextr does not recommend adding structured data for AI visibility. We checked all five engines in August 2026 and not one documents a requirement for it; Google states outright that there is “no special schema.org structured data that you need to add”. It also never recommends removing what you already have, because it does real documented work for Google rich results — the enhanced listings in ordinary search. A lower priority than it once was, not a mistake to be undone.
Not to be confused with the title tag and meta description, which we DO recommend writing. Those are page text an answer can quote. Structured data is a separate claim attached to the page.

Schema is a claim ABOUT the page. The title and the words on it ARE the page. An answer can quote the second.
Citation source
A page on someone else's site that mentions your business.
Worth more than anything you write about yourself, because it is corroboration rather than self-description. Which sources matter depends on the engine: measured across 144 real answers, ChatGPT drew about 97% of its citations from businesses' own websites, while Google AI Overview and Gemini leaned on directories like Yelp, Angi, Thumbtack and Houzz.
Credential (certification or membership)
A qualification you hold, usually displayed as a badge image.
The most credible fact about many businesses, and usually invisible. Put the credential in visible text, give the badge real alt text, and link it to your profile on the issuing body's site.
A photograph carries no text. The badge is a picture of a fact, and a picture is not something an answer can quote.
