GEO is a young discipline and the tool market is still developing rapidly. That doesn’t mean you should work without tools — but it does require a pragmatic combination of existing tools and manual processes.
AI visibility monitoring
Manual prompt testing
The most reliable method is still manual: systematically testing a structured prompt set in ChatGPT, Perplexity, Gemini and Claude, and documenting the results in a spreadsheet. Time-intensive, but fully controllable.
Specialised GEO tools (emerging)
A growing number of tools offer (semi-)automated AI visibility monitoring:
- Profound — specialised in AI brand visibility, measures mentions and sentiment across multiple models
- Brandwatch / Mention — social listening tools increasingly integrating AI platform monitoring
- Otterly.ai — focused on AI Search monitoring for brands
- Rankshift.ai — AI visibility tool with branded vs non-branded splitting and a Benelux prompt library, reports per prompt category and per platform separately
- Scrunch.ai — monitors AI answers on brand-relevant queries
Note: the tool market is evolving rapidly. Evaluate tools based on the models they monitor, prompt flexibility and export options for reporting.
