What an AI visibility audit includes and how to choose a GEO agency

Before investing in appearing in AI answers, it is worth knowing where you stand. That is what an AI visibility audit is: a diagnosis that measures your current presence and defines what needs fixing. Here is what it should include, what deliverables to expect and how to choose who to hire.

What an AI visibility audit is

It is a structured analysis of how the generative engines see — or do not see — you. It is not a classic SEO review: it measures your presence in the answers of ChatGPT, Gemini, Perplexity and others, identifies why you appear or not, and prioritizes the highest-impact actions. It is the logical starting point of any GEO strategy.

What it should include

• Share of Model Voice diagnosis: in what percentage of your industry's key prompts the models mention you, by engine and by market.
• Crawlability analysis: whether AI bots can read your site (robots.txt, performance, JavaScript dependency).
• Entity review: clarity and consistency of your identity and your schema.
• Citable content audit: how extractable your information is for your industry's prompts.
• Competitor benchmark: who beats you in the answers and why.
• Accuracy and hallucinations: whether models describe your brand well or invent data.

What deliverables to expect

A good audit ends in something actionable: a report with your current SoMV, the prioritized list of problems, concrete examples of AI answers about your brand and a roadmap with the highest-impact actions. If you only get metrics without a plan, half the value is missing.

How to choose a GEO agency

• One that really measures: it should show you how it quantifies your visibility (SoMV, citation rank) and not just opinions.
• One that covers several engines: visibility changes across ChatGPT, Gemini, Perplexity and others; measuring only one is insufficient.
• One that combines technical and content: real GEO touches crawlability, entity and content, not only copywriting.
• One that delivers verifiable results: measurable improvements over time, not vague promises.
• One that is transparent about its method: it should explain what it will do and how it will measure it.

What influences the cost

The price of a GEO consultancy depends on the scope: number of prompts and markets to monitor, number of engines, depth of the technical and content work, and languages. There is no single rate; that is why the sensible thing is to start with a focused diagnosis that shows the real size of the opportunity before committing to a larger program.

Questions worth asking before hiring

How will you measure my initial visibility and its evolution? In which engines and markets? What exactly does the technical and content work include? What does a successful result look like at three and six months? The answers to these questions will tell you far more than any pitch.

One-off audit or continuous program

An audit is a snapshot of the moment; AI visibility, in contrast, is a movie. Models update, competitors move and your own data changes. That is why it helps to distinguish two things: the initial diagnosis, which tells you where you are and what to prioritize, and the continuous program, which executes the improvements and measures again periodically.

For many companies the sensible path is to start with the focused audit, confirm the size of the opportunity with concrete data and only then decide whether sustained support is worthwhile. That way the investment is made in stages, with evidence at each step. What does not work is treating GEO as a one-off project: appearing one week and disappearing the next month, when the model updates, is exactly what a continuous measurement program prevents. If you want a starting point, an honest first look at your position against the models will give you clarity to decide. You can request a diagnosis and see your real situation before investing.
