GEO checker
Generative Engine Optimization checker: test your brand in AI answers
A Generative Engine Optimization checker diagnoses how AI engines currently answer your buyers' questions: whether your brand is mentioned, how prominently, which competitors are recommended instead, and which sources ground each answer. Buyers also search for GEO checking tools and GEO analysis tools; a good check is the starting baseline for any GEO program.
A GEO check runs representative buying-intent prompts against engines like ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews and reports mentions, answer positions, competitor appearances, and cited sources — the raw material for deciding what to fix first.

A practical buying filter
Check the questions buyers actually ask
A GEO check on your brand name flatters you. The revealing check is category prompts — "best X for Y", "alternatives to Z" — where engines make recommendations.
A checker without sources is half a diagnosis
Knowing you are missing is step one. Knowing the answer cited two roundups and a Reddit thread you are absent from is an action plan.
Baseline first, then rescan
Use the first check as a baseline, do the prioritized fixes, and rescan the same prompts to verify movement. One-off checks do not measure progress.

Questions buyers ask
- What is a Generative Engine Optimization checker?
- A tool that tests AI-generated answers for your brand, competitors, and cited sources across engines like ChatGPT, Gemini, Claude, Perplexity, and Google AI Overviews.
- Is there a free GEO checker?
- Yes. Visibly's free scan checks whether AI answers mention your brand and shows initial gaps before you commit to a plan.
- What should a GEO check report?
- Brand mentions per prompt and engine, answer position, competitors recommended instead, and the sources each answer cited.
- How is a GEO check different from GEO tracking?
- A check is the diagnostic snapshot; tracking rescans the same prompts on a schedule so you can verify whether fixes changed the answers.
