How much does a GEO audit cost in 2026?
By The Venoh team · Last updated September 25, 2026
A GEO audit can cost nothing or several thousand dollars, and the price mostly reflects how many AI engines and buyer questions are tested, how deeply the results are analysed, and whether anyone writes the fixes for you. These are the published figures we could verify, with a link to each source.

What changes the price
- How many engines and questions are tested. Mentionable's guide ties retainer tiers directly to this: 20-30 prompts on 3 LLMs at the low end, 80-200 prompts on 7 LLMs at the high end.
- Whether a person analyses the results. Automated scores are cheap because nobody interprets them for your business; agency audits price in analyst time.
- Whether the fixes are written for you. A list of problems is cheaper than drafted FAQ content, structured data and page outlines your team can use as-is.
- Competitive depth. Measuring who appears instead of you, and on which pages the engines rely, takes far more queries than checking your own site.
How to choose
- Use a free score to find out whether you have a problem at all.
- Use a one-off diagnostic when you need to know why you are missing from AI answers, who is showing up instead, and exactly what to fix, before committing to a retainer.
- Use a retainer or monitoring platform once you are implementing fixes and need to track answers over time.
Whatever you buy, ask which engines are tested, how many questions, whether the questions avoid naming your brand (otherwise the test flatters you), and whether every number in the report is counted from real answers. Be wary of anyone who guarantees citations or rankings: nobody controls what an AI engine says.

Is a free GEO diagnostic enough?
It can tell you whether you have a visibility problem. It usually will not tell you which competitors and third-party pages are winning your buyers' questions, or give you content and markup ready to publish. See our comparison of free and paid diagnostics.
