What is an AI visibility audit?

An AI visibility audit is an assessment of how a brand appears in AI-driven search, such as ChatGPT, Gemini, Perplexity and Google AI Overviews. It records whether the brand is mentioned or cited for the prompts buyers use, how it is described, which competitors and sources appear instead, and what on the site or across the web is holding it back. It ends with a prioritised plan of fixes.

Which AI platforms does the audit cover?

As standard, ChatGPT, Gemini, Perplexity and Google AI Overviews. We can add Google AI Mode, Claude, Microsoft Copilot or other assistants where they matter to your audience. Each platform retrieves and cites sources in its own way, so results are reported for each one as well as overall, and the plan notes where a fix helps one platform more than another.

How is an AI visibility audit different from AI brand monitoring?

An audit is a point-in-time diagnosis: where you stand, why, and what to do about it. AI brand monitoring is the ongoing tracking that follows, running the same prompts on a regular schedule to see how mentions, citations and descriptions change over time. Answers vary between runs, so monitoring is what turns a snapshot into a reliable trend. The audit sets the baseline that monitoring measures against.

Is your free Chrome extension the same as an audit?

No. Our free GEO & AI Visibility Checker for Chrome gives a fast snapshot of a single page: which AI crawlers robots.txt allows, structured data, how quotable the content is, llms.txt and whether content depends on JavaScript. The audit looks across your whole site and the wider web, tests real prompts on each platform, analyses the sources cited and gives you a prioritised plan.

What do we need to provide for the audit?

A short briefing on your priority products, services and markets, the competitors you care about most, and access to your analytics and Google Search Console so we can see search performance and any attributable AI referral traffic. Input from sales or customer service on the questions buyers ask is valuable when we build the prompt set. We handle the testing, analysis and plan.

AI Visibility Audit With A Plan Attached

Before you invest in AI search, you need to know where you stand. Our AI visibility audit shows where your brand appears today in ChatGPT, Gemini, Perplexity and Google AI Overviews, which sources they cite instead of you, what is stopping them from reading or trusting your site, and a prioritised plan for what to fix first.

We’ve Helped Dozens Of Great Brands Grow Their Digital Presence Via Search Marketing

You can’t fix what you can’t see. Start with the evidence.

Most marketing teams can report their Google rankings in detail but have little idea what AI assistants say about their brand. Competitors may be named in answers you are missing from, and the descriptions AI systems give of your business may be out of date or simply wrong.

The audit replaces guesswork with a baseline. We test the prompts your buyers actually use, record what each platform says and cites, check your site and wider web presence for the reasons behind it, and set out the actions most likely to change the picture, ranked by commercial value.
