How to Measure Your Brand's AI Visibility
AI search has no rankings and no analytics. Here is how Centium measures whether AI recommends your brand, across five models and hundreds of prompts.
ai search has no scoreboard.
When you run Google Ads or track SEO, you have data: impressions, rankings, clicks. AI search gives you none of that. There is no Google Search Console for ChatGPT, no ranking report for Gemini. A buyer can be fifteen prompts deep in a conversation before a model names a single brand, and none of it lands in your analytics.
So most brands are flying blind. They have no idea how often AI recommends them, against whom, or whether it recommends them at all. AI answers questions about your brand every day, from both its trained memory and live web search. Measuring it means turning that black box into numbers you can act on.
ask what buyers ask, not what flatters you.
You cannot measure AI visibility by asking a model whether your brand is good. Name your brand and it will almost always say yes, which tells you nothing about whether AI brings you up on its own. So for the visibility number, Centium asks the questions real buyers ask, at the category level: "best trail running shoes," "top project management tools for small teams," "where should I stay in Park City." Your brand stays out of those prompts, which is what keeps the recommendation rate unbiased. Centium runs brand search too, asking about your brand by name, but as a separate segment for perception, kept out of the visibility math so it never inflates the rate.

We run those questions at scale, hundreds of prompts across the five models that matter, and we run each angle many times, because a model does not answer the same way twice. Ask once and you get an anecdote. It is like calling a coin flip: ten flips is noise, a hundred flips shows the real pattern. We flip it a hundred times.
what share of answers name you.
All of it rolls up into one number: your recommendation rate, the share of category prompts where AI names your brand. It is the core metric of AI visibility and the cleanest way to track progress over time.
Because every prompt runs across all five models, you can filter the rate to any model and see where you are strong and where you vanish. A brand can sit high in ChatGPT and near zero in Gemini, and a single blended number would hide that. The breakdown is where strategy starts.

every model sees you differently.
Your visibility is never one number, because each model is its own persona with its own instincts and sources. ChatGPT leans on Wikipedia. Gemini pulls from YouTube and Reddit. Perplexity chases whatever was published most recently. The same question can name a different set of brands in each one.
Centium measures your rate in every model separately, so you know which already recommend you and which never do. That points straight at the work: the model you are missing from, and the sources it favors that you are not part of yet.
reverse-engineer the decision.
Measuring how often you appear is half the value. The other half is understanding why. After a model answers, Centium asks it what factors drove the decision, and records every source and citation it leaned on. Across hundreds of prompts, clear patterns emerge: the review sites AI trusts in your category, the decision factors it weighs, and the way it describes you when it does recommend you.
From there it stops being a report and becomes a plan. Centium turns the data into a prioritized list of what to fix first, so you are not just measuring how AI sees your brand, you are doing something about it.
questions, answered.
You measure it by asking AI models the questions your buyers ask, at scale, and recording how often each one names your brand. Centium runs hundreds of category-level prompts across ChatGPT, Claude, Gemini, Perplexity, and Grok, then reports your recommendation rate, the sources each model cited, and how you compare to competitors.
Yes. There is no native analytics for AI answers the way Google Search Console reports search, so the only way to track it is to prompt the models directly and at scale. Centium does that across five models on a recurring schedule, so you can see your mention rate and watch it move over time rather than running one-off spot checks.
Because naming your brand biases the answer. Ask a model "is my brand good?" and it will almost always say yes, which measures nothing. Asking the questions buyers actually ask, like "best trail running shoes," with no brand in the prompt, is the only way to see whether AI brings you up on its own.
No. The same prompt can return different brands on different runs, which is why a single test is just an anecdote. Centium runs each angle many times across all five models, the way you would flip a coin a hundred times instead of ten, so the recommendation rate reflects a real pattern rather than the luck of one answer.
ChatGPT, Claude, Gemini, Perplexity, and Grok. Each one is treated as its own persona, because each favors different sources and can name a different set of brands for the same question. Measuring them separately is the only way to see which models already recommend you and which never do.
It is the percentage of category prompts where AI names your brand, with no brand prompting to bias the answer. It is the core metric of AI visibility, comparable across runs, and you can filter it by model to see where you are strong and where you disappear.
