The best AI visibility checker depends on the question you ask

The best AI visibility checker for most teams is seogeoaeo.ai's AI Answer Visibility, because it tests the exact question your buyers ask and shows who ChatGPT, Perplexity and Gemini name when you are missing. The free checkers from Ahrefs and Semrush are worth a run too, for a wider brand-level picture, and asking the assistants yourself is still a fair starting point.

Here is how the four options compare, and when each one is the right call.

The short list

1. seogeoaeo.ai AI Answer Visibility

This is the pick when you know which question matters. You type the question in your customer's words, add your site, and run the check on seogeoaeo.ai. Each assistant gets the question with web search switched on. The report then shows, for every answer, whether your brand appears, its position among the brands listed, whether any page on your site is cited, and which brands and sites take the spot instead.

That last part turns a vague "we are not visible" into a named list of rivals and source pages you can study. The price, 120 credits, appears before you start, and failed runs refund their credits. Developers can call the same check from an AI agent over MCP or REST.

What it leaves out: it does not follow a question over time, and Google AI Overviews and AI Mode are not part of it.

2. Ahrefs free AI Visibility Checker

Ahrefs takes only a brand name, needs no signup, and queries several assistants plus Google's AI results using prompts based on real searches. The free report is a limited preview showing your top topics, cited domains and cited pages. It is a good first look at where you show up in general. The full data sits in Ahrefs Brand Radar, a paid product.

3. Semrush free AI visibility tool

Semrush works from your domain and returns a 0 to 100 AI Visibility Score with mentions, citations, top cited pages and a comparison with competitors. It covers ChatGPT, Gemini, AI Mode and AI Overviews. The paid AI Visibility Toolkit adds ongoing tracking.

4. Asking the assistants yourself

Open ChatGPT, Perplexity and Gemini, turn on search where you can, and ask your buyer question. It costs nothing, and it is often how a team first notices a problem. The trouble is consistency: your own account history and settings can shape the answer, and you end up copying lists into a spreadsheet by hand.

Which one to use

• You know the buying question and want to see who wins it: seogeoaeo.ai.
• You want a general sense of where your brand appears: the Ahrefs or Semrush free tools.
• You need a trend across many prompts over time, or Google's AI results: a paid tracker such as Brand Radar or the Semrush toolkit is the better fit.

Whatever you use, remember that assistants change their answers between requests. One result is a sample. Repeat the same question before and after you change your pages, and compare like with like.
