Free AI Visibility Checker. Check Your Site's AI Search Visibility

Is your website visible to AI? This free AI visibility checker analyzes your site across ChatGPT, Gemini and Perplexity. Get your AI visibility score with instant, actionable results.

What Does the AI Visibility Checker Analyze?

AI visibility is the new frontier of SEO. AI engines like ChatGPT, Gemini and Perplexity now cite websites directly in their responses. This free AI visibility checker tests whether your content is structured in a way that AI systems can discover, understand, and quote.

The AI visibility check covers multiple dimensions: bot access (can AI crawlers reach your site?), content citability (are your paragraphs quotable?), structured data (is your Schema markup correct?), technical SEO health, and E-E-A-T signals. You get an AI visibility score from 0 to 100 with specific, actionable recommendations.

Improving your AI visibility requires quality content, correct technical structure, and a strong digital presence. TopicPen specializes in AI visibility optimization tools and strategies that make your site visible across all AI engines. This AI visibility checker is completely free with no signup required.

Frequently Asked Questions

What does the AI visibility checker test?+
This AI visibility checker analyzes whether AI engines like ChatGPT, Gemini and Perplexity can find, understand, and cite your content.

The tool checks access for the following bots:
  • GPTBot (ChatGPT)

What is Generative Engine Optimization (GEO)?+
Generative Engine Optimization (GEO) is the practice of optimizing your website for AI-powered search engines. Unlike traditional SEO that targets Google rankings, GEO focuses on making your content citable by AI systems like ChatGPT, Gemini, Perplexity and Claude. This includes writing quotable paragraphs, adding proper structured data, and ensuring AI bots can access your site.
How does AI search optimization differ from traditional SEO?+
AI search optimization goes beyond keywords and backlinks. AI engines evaluate content quality (E-E-A-T), structured data, citability, and whether your content directly answers questions. Traditional SEO gets you ranked in search results. AI search optimization gets your content quoted in AI responses, which is increasingly where users find answers.
