SiteSignal
SiteSignal's AI visibility checker runs the questions your buyers ask through ChatGPT, Gemini, Perplexity and Google AI Overviews. It shows whether those engines name your brand, what they say about you, which competitors they recommend instead and what to fix first. Start a 7-day free trial to check your own brand.
What the AI visibility checker shows
- Visibility by engine: how often each AI engine mentions, recommends, ranks and cites your brand.
- Competitors: which brands AI names instead of you, question by question.
- Brand accuracy: facts AI gets wrong about you, such as prices, contact details or services.
- Cited sources: the websites AI relies on when it answers questions about your market.
- Query fan-out: the hidden searches AI engines run before they answer.
- AI crawler access: whether GPTBot, PerplexityBot and other AI crawlers can read your site.
- Website health: uptime, response time and SSL, because an offline site can't be cited.

Why AI visibility matters now
AI assistants are becoming the first place buyers ask for recommendations. Gartner expected traditional search volume to fall 25% by 2026. Capgemini found 58% of consumers have replaced traditional search engines with generative AI tools for product and service recommendations, and Forrester found 89% of B2B buyers use generative AI in at least one part of their purchasing process.
In SiteSignal's UK workwear study, 17% of AI fact-checks about brands were flat wrong and 12% more were partly wrong, across 4,903 checks. If AI engines get your facts wrong, or never mention you, buyers go to a competitor without ever visiting your site. That is what AI search optimization (AI search optimisation in the UK), also called answer engine optimization or AEO, fixes.
