What Is a GEO Score? How AI Visibility Scores Work (and How to Read Yours)

A GEO score is a single number, usually from 0 to 100, that summarises how visible and trusted your brand is in AI search engines such as ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. It rolls up signals like whether engines mention you, how clearly they understand what you do and how much outside authority backs you up. Treat it as a health check, not a ranking.

What does GEO score mean?

GEO stands for generative engine optimization: the work of getting your business found, understood and recommended by AI engines that write answers instead of listing links. If you are new to the idea, start with our complete guide to GEO.

A GEO score tries to answer one question quickly: if someone asks an AI assistant about my market, how likely is it to know me, trust me and name me? It is the AI-search counterpart of the “SEO score” many site audit tools show, but it looks at different things.

What goes into a GEO score?

Tools weigh things differently, but most GEO scores combine some version of these signals:

On Onxeera, the AI visibility checker returns an overall GEO score plus separate visibility, brand mention and authority scores and a breakdown by content quality, brand authority and technical foundation, so you can see which part is pulling the total down.

How is a GEO score calculated?

There are two broad approaches, and it helps to know which one you are looking at:

1. Measured from answers. The tool asks AI engines real questions and counts how often you are mentioned. This is the most direct evidence, but it needs many answers to be stable, because AI replies vary from run to run.
2. Assessed from signals. The tool looks at your site and your footprint on the web and rates how well they match what AI engines tend to use. This is fast and gives a useful breakdown, but it is an estimate.

The Onxeera checker gives you a fast assessed score. Prompt Research gives you the measured side, from real answers. Used together, one tells you why, the other tells you what is actually happening.

What is a good GEO score?

There is no universal benchmark yet. As a working guide for scores from the same tool:

• 0 to 39: barely visible. Engines know little about you or cannot read your site well. Start with the basics: crawler access, clear business facts, a few trusted profiles.
• 40 to 69: known but inconsistent. You appear sometimes, often below competitors. Work on authority and the sources engines cite.
• 70 to 100: strong signals. Keep facts consistent, keep publishing useful content, and watch competitors.

The more useful comparison is your score against two or three direct competitors, checked with the same tool on the same day. Our guide to AI share of voice explains how to compare yourself fairly.

Why GEO scores move around

If your score shifts a few points between checks, that is normal. AI engines update their models and search sources, the web changes, and any assessed score carries some judgement. Read changes like this:

• Under 5 points: noise. Do not react.
• 5 to 10 points: worth a look. Check which breakdown score moved.
• More than 10 points, or a steady trend over several checks: a real change. Look for a cause, such as a site migration, a robots.txt change or new press.

How do you improve your GEO score?

Go after the weakest part of the breakdown first. The most common fixes, roughly in order of effort:

1. Let AI crawlers in. Make sure robots.txt does not block search crawlers such as OAI-SearchBot, Claude-SearchBot and PerplexityBot. See how to allow AI crawlers in robots.txt.
2. State your facts clearly. Name, category, location, services and contact details should be the same on your site and every profile. Add Organization or LocalBusiness schema.
3. Answer real questions on your pages. Short, direct answers and FAQs are easier for engines to quote.
4. Get mentioned where engines look. Directories, review sites, “best of” lists and industry articles often matter as much as your own site.
5. Re-check and compare. Run the same check again after changes have had time to be crawled, usually a few weeks.

A worked example: reading a GEO score breakdown

Say a physiotherapy clinic in Leeds gets an overall GEO score of 46. On its own, that number only says “middle of the road”. The breakdown tells the real story:

Rewriting the homepage again would not move much here. The weak spot is authority: reviews and listings on the sites engines read for “best physio in Leeds”. That is where the next month of work should go. Two competitors checked the same day scored 58 and 63, which confirms the gap is real and shows roughly how far there is to go.

Illustrative example. Your own breakdown will differ.

GEO score vs other AI visibility metrics

No single metric is enough. The GEO score points you at the problem; the others confirm it with evidence from real answers. For the difference between being named and being cited, see AI mentions vs AI citations.

The limits of any single score

A GEO score is a summary. It cannot tell you exactly which questions you win or lose, and it cannot promise that an engine will mention you tomorrow. Use it to spot weak areas and to track direction. When a decision matters, look at real answers: check what ChatGPT actually knows about your brand and which competitors it names instead.

Frequently asked questions

What is a good GEO score?

There is no industry standard, because every tool scores differently. As a working guide for Onxeera scores, under 40 means AI engines barely know or trust you, 40 to 69 means you are known but not consistently recommended, and 70 or above means strong signals. Compare yourself with direct competitors rather than with an absolute number.

Is a GEO score the same as an SEO score?

No. An SEO score usually looks at how a page is built for Google's ranked results. A GEO score looks at whether AI engines can find, understand and trust your brand enough to name it in an answer. The two overlap, but a site can do well in one and poorly in the other.

Why did my GEO score change when I did nothing?

AI engines, their sources and the web itself keep changing, and part of any GEO score is an assessment rather than a fixed count. Small moves of a few points are normal. Look at the trend over several checks and at the underlying signals, not a single number.

Can a GEO score guarantee that ChatGPT will mention me?

No. A GEO score is a summary of signals that tend to matter. No tool can promise a mention, because AI companies do not publish how they choose brands. Pair the score with real answers from tools like Prompt Research to see what engines actually say.
