AI visibility score for ChatGPT, Gemini and Perplexity

What is an AI visibility score?

An AI visibility score is a measure of how often the AI engines mention your brand when people ask them about what you do. On a MentionChecker report it is three numbers at the top of every check, Mentioned, share of voice and average rank, each counted from the answers on the same report, so any of the three can be checked by opening the answers behind it. The What is AI visibility page defines the measure and the work behind it.

MentionChecker is a pay-as-you-go AI visibility checker. It asks ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Microsoft Copilot the questions people ask about what you do, and tells you whether your brand is mentioned in the answers. A mention is an answer with your brand in it. A citation is a page an AI engine lists under its answer as its source, and the report keeps every citation under the answer it came with.

How is an AI visibility score calculated?

An AI visibility score is calculated as three counts, each over its own denominator: Mentioned is the answers with your brand in them over every answer that came back, share of voice is your mentions over every mention of every name, and average rank is your average place over the answers that listed names in order. A MentionChecker check asks the questions people ask about what you do on the AI engines you pick, from one country, and reads every answer for your brand, for every other name it mentioned and for the order it listed them in.

A question an AI engine gave no answer to is not counted. Google's help page says an AI Overview appears in the results when its systems determine that generative AI can be especially helpful (Find information in faster & easier ways with AI Overviews in Google Search, read on 20 September 2026), so a question Google served no AI Overview for is recorded on the report as served no AI answer and left out, which is how 14 questions on four AI engines are 51 answers in the screenshots: 56 were asked and five came back with no AI Overview.

How is Mentioned counted in an AI visibility check?

Mentioned is the share of the check's answers with your brand in them, and it is the number the headline says in a sentence. An answer counts once however many times it mentions you, so a mention rate of 45% on 51 answers is 23 answers.

Each question carries its own count, so the questions with none are the ones to open first.

At zero the headline says AI never mentions your brand.

What is a good AI visibility score?

A good AI visibility score is one higher than the names you want to beat, because no mention rate is good on its own: a rate is read against the names the answers gave, and the same question gets a different list from each AI engine. On 18 September 2026 we asked six AI engines for cosy puzzle games with no ads from the United States: all six answered with a list, no name was on more than two of the six lists, and so the highest mention rate any name could have had on that question was 33%, two answers of six.

The comparison is on the same report. The standings rank every name the answers mentioned by the share of answers that mentioned it, with your row marked, so a good score is one that puts your row above the rivals you measure yourself against, and the AI rank tracker page describes the standings. Against your own past checks, History shows each number with its movement, so a good score in October is one that moved up from September on the same questions.

How is share of voice counted in an AI visibility check?

AI share of voice is your mentions as a share of every mention in the check, all names counted together, whichever AI engine gave them. Under it the report gives your place: 3rd of 10 names the answers gave means the answers mentioned ten names in all and two of them were in more answers than yours. Two names with the same count share a place, and the place is shown only when you were mentioned at all.

Share of voice moves with every name's count as well as yours. Between two checks it can fall while your own count rises, if a rival was added to more answers than you were, and it can rise with your count unchanged when a rival dropped out of the answers.

A review site or an app store in the standings can be excluded from share of voice, with nothing asked again and nothing charged, and put back later.

How is average rank counted in an AI visibility check?

Average rank is your average place in the answers that listed names in order, shown once at least three answers ranked you, with the count of listings beside it, and a dash that says never listed in order below that. An answer that mentions you without ranking anything gives no place, so the average is over listings alone and 1 is first: 2.5 over 10 listings means ten answers put the brand in an ordered list, and its places in them average to 2.5.

An average of 2.5 is read back to the ten answers behind it, each open on the report with the place it gave. On History the movement of the average is the difference against the check before, shown as down when the place got worse, because a lower average rank is the better one.

Why does an AI visibility score change?

An AI visibility score changes when the answers change, and the answers change on their own. OpenAI's help page says ChatGPT may search the web when a question would benefit from current information, and that its results and citations can be incomplete, outdated or incorrect (Searching the web with ChatGPT, read on 18 September 2026), so the same question can get a different answer, with different names in it, from one check to the next. The other four things that move the numbers are yours: more questions, a different pick of AI engines, an excluded name and a different country.

History gives each number its movement against the check before, counted on the answers both checks cover, so a check that asked more questions than the one before never reads as every number falling at once. A repeat asks exactly the AI engines the check it repeats asked, with the same questions and country, so each check compares with the one before, and the AI visibility tracking page shows the repeat and what History counts.

Which AI engines does an AI visibility check cover?

A check asks up to six AI engines, ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Microsoft Copilot, and counts the ones you picked. ChatGPT, Google AI Overviews, Gemini and Perplexity are in the default pick, Google AI Mode and Microsoft Copilot are there to add when you set the check up.

The three numbers count every AI engine's answers together, so a check on four AI engines gives one score. The split is on the same report: every question lists the AI engines that answered it and how many of those answers mentioned you, and History keeps one line per AI engine, so a rise on Perplexity is read apart from a fall on ChatGPT. The guide to checking your ChatGPT visibility covers a first check on ChatGPT alone, where every number is counted over ChatGPT's answers only, and the guides to checking your Gemini visibility, checking your Perplexity visibility, checking your Google AI Overviews visibility, checking your Google AI Mode visibility and checking your Copilot visibility cover the same check with Gemini, Perplexity, Google AI Overviews, Google AI Mode or Copilot selected.

What is an AI visibility audit?

An AI visibility audit is a one-off reading of where a brand stands in AI answers: which questions it is mentioned on, which it is not, who is mentioned instead, and which websites the answers cited. A MentionChecker check is one, read as a report: the three numbers, the standings of every name the answers mentioned, the sources list, and every answer word for word, on one page.

An AI visibility audit differs from an SEO audit in what it reads. An SEO audit reads your website and your positions in a results list, and an AI visibility audit reads the answers, which have no results list, so it asks the questions and counts what came back. What the two share is the sources list: it says which pages the answers cited, with your own site marked, and the AI citation checker page describes how those pages are ranked.

How do you run an AI visibility audit?

Run one check and read its report. An AI visibility audit takes as long as the check runs: a check of 14 questions on four AI engines from the United States ran for two minutes and 23 seconds on 9 September 2026, read from its own record.

1. Enter your website. The check proposes the questions people ask about what you do, and you approve, edit or add to them.
2. Pick the AI engines and the country. ChatGPT, Google AI Overviews, Gemini and Perplexity are ticked to start, and the country is preselected from your web address.
3. Read the report. The three numbers first, then the name mentioned more often than you, then the questions with none of their answers mentioning you, then the websites the answers cited.
4. Send it on. Share copies a link that opens for anyone without a login, and Export saves the report as a PDF, so whoever asked for the audit reads the same page you did. The AI visibility report page describes the link and the exports.

An audit run again is tracking. Every brand in an account has its own checks, so an agency audits every client from one account.

How do you improve an AI visibility score?

Start with the questions whose count on the report reads zero: none of their answers mentioned you, and each answer is on the report word for word, with the names it mentioned instead beside the question and the pages it cited under it, so the topic the AI engines do not connect you with is read from the answer itself. Then the sources list. It ranks the pages the answers cited across the whole check, the most cited first, a review site, a comparison article or a directory among them, with your own site marked when it is one of them.

Then the standings, for the names above yours: open the answers that mentioned them and read what those answers say about them and which pages they cite. Change what you can on your own site and on the pages the answers cite, run the same check again, and History shows which of the three numbers moved and by how much.

How much does an AI visibility audit cost?

An AI visibility audit costs one credit for each question on each AI engine, asked once: 25 questions on the four AI engines a check asks by default is 100 credits, the smallest pack is 50 credits for $9, and your first check is free: 5 questions on ChatGPT and Gemini, no card. There is no plan: the credits come from a pack bought once, and they last 12 months, the way a pay as you go AI visibility tracker is paid.

Prices as of 20 September 2026, read from the pricing page.

How does an AI visibility score compare with an AI visibility index?

An AI visibility score on a MentionChecker report is three counts from your own questions, answers, mentions and listings, each on the same report, and an AI visibility index is one number a tool computes for a brand from the questions it chose, weighted the way that tool weights them, with a table of brands ranked by it.

A check gives counts you can open and verify, answer by answer: every line on the right is one report, from $9 on the pricing page, read on 20 September 2026.

What do people ask about an AI visibility score?

Why does an AI visibility score matter?

Because when an AI engine answers with a list of names, a brand not on it is not seen by the person who asked. The score on a MentionChecker report says how often you were on that list across the questions people ask about what you do, who was on it instead, and where you were placed, counted from answers you can open. It is the number to know before deciding what to change, and the same check run again shows whether the change reached the answers.

Is there a free AI visibility checker?

Yes. Your first MentionChecker check is free, no card: 5 questions on ChatGPT and Gemini, and its report carries the same three numbers as any other, Mentioned, share of voice and average rank, with the standings and every answer under them. After it a check costs one credit per question per AI engine, and the smallest pack is 50 credits for $9 on the pricing page, read on 20 September 2026.

Why did my AI share of voice fall when my mentions rose?

Because share of voice is your mentions as a share of every mention in the check, all names together. If a rival was added to more answers than you were between two checks, the total grew faster than your count, so your share fell while Mentioned rose. A MentionChecker report shows both, with your place among the names the answers gave under the share of voice, and History shows each with its movement against the check before.

What is average position in an AI visibility score?

Average position is average rank on a MentionChecker report: your average place in the answers that listed names in order, shown once at least three answers in the check ranked you, with the count of listings beside it, and a dash below that. An answer that mentions you without ranking anything gives no place, and a check with more questions gives the average more listings behind it.

Is a lower average rank better?

Yes. Average rank on a MentionChecker report is your average place in the answers that listed names in order, so 1 means every answer that ranked you put you first, and a higher number means those answers put you further down. On History the movement is shown as down when the place got worse, so 2.1 to 2.5 reads as down 0.4. Run the same check again and History shows which way it moved.

Do review sites count in share of voice?

Until you exclude them. Every name the answers mentioned is in share of voice to start, a review site or an app store included. Exclude on that name's row of a MentionChecker report takes it out at once, with nothing asked again and nothing charged: the latest check is recounted, its mentions leave the total, so your share rises and your place can move. Mentioned does not change, because it is a share of answers, and average rank does not, because it is over the answers that ranked you.

Does an AI visibility score include citations?

The three numbers count mentions, and citations are read beside them. Mentioned, share of voice and average rank on a MentionChecker report are counted from the names in the answers, and every page an AI engine listed under an answer as its source is kept under that answer, with your own site marked when it is one of them. The sources list ranks those pages across the whole check, the most cited first, and the AI citation checker page describes how it is read.

Does an AI visibility score measure sentiment?

No. The three numbers on a MentionChecker report count whether each answer mentioned you, your mentions against every other name's, and the place the ranking answers gave you. What an answer says about you is not scored, it is on the report word for word, under the question it answered, with the pages it cited beneath it, so how ChatGPT or Gemini describes your brand is read there, one answer at a time.

Does an AI visibility score show traffic from AI?

No. The score counts mentions in the answers, not visits from them. A MentionChecker report says how often you were in the answers, how your mentions compare with every other name's and where you were placed, on questions you chose, and it does not read your analytics. It is the step before a visit: whether the person who asked was shown your brand at all. Run the same check monthly and read History beside your own visit numbers.

Can I share my AI visibility score?

Yes. Every MentionChecker report has Share, which copies a link anyone opens without a login, and Export, which saves the report as a PDF, as Markdown or as JSON, with the three numbers, the standings and every question in each. A past check opens as the report it was on the day it ran, so the numbers from three months ago can be sent on as they were. The AI visibility report page describes the link and the exports.

How many questions does an AI visibility check need?

Enough answers for a share to mean something, and MentionChecker proposes the questions from your website so you start with a list. A check of 25 questions on the four AI engines a check asks by default, for example, is up to 100 answers, so one answer is one point of the mention rate, and average rank is shown once three answers have ranked you. Your first check is free and asks 5 questions on ChatGPT and Gemini.

How often should I check my AI visibility score?

Run one MentionChecker check, then the same check a month later, and decide from what moved. A repeat runs the same check daily, weekly or monthly from your balance, and History gives each number its movement against the check before, counted on the answers both checks cover. A monthly repeat of 25 questions on the four default AI engines is 100 credits a month. The AI visibility tracking page describes the repeat.

Does the country change my AI visibility score?

Yes. A brand checked from two countries gets one report and one History series per country in MentionChecker, and every number is counted over that country's answers. On 18 September 2026 ChatGPT listed eight cosy puzzle games from the United States and nine from the United Kingdom, and not one name was in both. The check asks from the country the people you serve are in, preselected from your web address, and the report's first line names it.

What does it mean if AI never mentions my brand?

AI never mentioning your brand means no answer in the MentionChecker check mentioned you. The headline says never, Mentioned reads 0% of the check's answers, share of voice reads 0% of all mentions with no place under it, and average rank is a dash. Under the headline the report shows the brand mentioned most often instead, with its share of the same answers, and the standings rank everyone the answers mentioned, which is where to start.

Is an AI visibility audit the same as an SEO audit?

No. An SEO audit reads your website and your positions in a results list for a set of keywords. An AI visibility audit reads the answers the AI engines give to the questions people ask about what you do, and an answer has no results list, so it counts whether you were mentioned, who else was, and which pages the answers cited. A MentionChecker check is that audit as one report, with every answer on it.

How long does an AI visibility audit take?

As long as the check runs. A MentionChecker check of 14 questions on four AI engines from the United States ran for two minutes and 23 seconds on 9 September 2026, from its own record, and the report opened when it finished, with the three numbers, the standings, the sources and every answer on it. Setting the check up is entering your website and approving the questions it proposes.
