GEO Tool FAQ

What is the difference between GEO and SEO?
SEO optimizes for traditional search engines (Google rankings, backlinks, keywords). GEO optimizes for AI search engines — it is about being cited by ChatGPT, Perplexity and others. GEO focuses on structured data, direct answers, entities, and AI readability instead of link building.
Why is my website not cited by ChatGPT?
The most common reasons: 1) No Schema Markup (JSON-LD), 2) No clear definition paragraphs ChatGPT can use as answers, 3) Missing llms.txt file, 4) Content not linked as entities, 5) Too little structured data (tables, lists, FAQ). The GEO Tool shows you exactly which barriers exist.
Who is the GEO Tool for?
Anyone who wants to be visible online: marketing managers, SEO agencies, freelancers, startup founders, and e-commerce managers. Especially relevant for companies realizing that traditional SEO alone is no longer sufficient as more users switch to ChatGPT and Perplexity instead of Google.
Which AI search engines does the GEO Tool check?
The GEO Tool checks visibility for ChatGPT (OpenAI), Perplexity AI, Google AI Overviews, and Claude (Anthropic). Each engine is scored separately, so you can see where you perform well and where optimization is needed.
What is a good GEO Score?
A GEO Score below 30 means your website is practically invisible for AI searches. 30–60 is average. Above 60, you are better than most websites. Above 80, you have a high chance of being cited in AI answers. Top websites achieve scores above 90.
