A GEO score is a 0 to 100 measure of how ready a website is to be crawled, understood and cited by AI-powered search and answer systems such as ChatGPT search, Google AI Overviews, Perplexity, Gemini and Claude. It does not show a ranking inside any AI product. Instead, it measures the signals you control that make your pages easier for those systems to find, interpret and trust as a source.
GEO stands for Generative Engine Optimization. Where SEO asks "will this page rank in a list of links?", GEO asks "will an AI system that writes an answer be able to use this page, and is there enough evidence to trust it?" A GEO score turns that question into something you can measure and improve.
What a GEO score measures
On GEO Score Checker, the score is a weighted average of six dimensions. Each is scored from 0 to 100:
| Dimension | Weight | The question it answers |
|---|---|---|
| Technical AI Readiness | 20% | Can crawlers reach and interpret the page? HTTPS, title, meta description, canonical URL, structured data, sitemap, robots.txt and AI crawler access. |
| Content & Answerability | 20% | Does the page answer real questions clearly? Content depth, headings, lists, FAQ content, internal context and image descriptions. |
| Entity Clarity | 15% | Is it obvious who you are, what you offer, for whom and where? |
| Citation / Source Potential | 15% | Do independent, relevant sources reference you? |
| Web Authority | 15% | How broad and credible is the independent evidence about you? |
| AI Visibility Evidence | 15% | Is there observed evidence of the site appearing in AI answers? |
One rule matters more than any weight: a dimension that cannot be measured is excluded, not scored as zero. If no direct AI visibility evidence is available, the other five dimensions are rescaled to 100%, and the report shows the measured coverage. The full formula, every signal and a worked example are on the GEO score methodology page.
What is a good GEO score?
- 90 to 100, Excellent: strong foundations everywhere that was measured.
- 80 to 89, Strong: well prepared, usually with one weaker dimension.
- 70 to 79, Good: solid technical base; gains come from clearer answers and entities.
- 50 to 69, Needs improvement: visible gaps such as missing structured data or thin answers.
- Below 50, Weak: fundamental problems, often blocked crawlers or very little crawlable content.
The most useful comparison is not an absolute number but your score against the sites that currently get cited for your topic. Check a competitor's page alongside your own and look at which dimension separates you.
What a GEO score is not
A GEO score is not a ranking in ChatGPT or Gemini. AI products do not publish rankings, and their answers change with the prompt, the user, the location and the day. Any tool that shows a precise "ChatGPT rank" for your site without showing the answers it observed is guessing.
It is also not a Google ranking factor. Google does not use third party scores. Many of the signals overlap with good SEO, such as crawlability, clear structure and structured data, so improving your GEO score often helps traditional search as well, but the score itself is a diagnostic.
How the GEO score differs from SEO metrics
| Traditional SEO metrics | GEO score | |
|---|---|---|
| Goal | Rank in a list of links and earn clicks | Be understood and used as a source in AI answers |
| Typical inputs | Keywords, backlinks, positions, traffic | Crawl access for AI bots, answerability, entities, independent references |
| Unit of success | Position and click | Inclusion and citation |
| Missing data | Usually estimated | Excluded and reported as unmeasured |
How to improve your GEO score
Work on the lowest dimension first. In practice, this order fixes most sites fastest:
- Unblock AI search crawlers. A single
Disallow: /underUser-agent: *blocks every AI search bot. Test your robots.txt with the AI crawler checker, and remember that blocking GPTBot (training) does not need to block OAI-SearchBot (ChatGPT search). - Fix the technical basics. HTTPS, one descriptive title, a meta description, a self-referencing canonical and valid JSON-LD for your organisation and key pages. The schema generator creates the markup.
- Lead with the answer. Put a one or two sentence direct answer near the top of each important page, then expand with H2 and H3 sections, lists and a short visible FAQ.
- State your entity explicitly. Name your organisation, what you offer, who it is for and where you operate, consistently on your site and your profiles, and link them with
sameAs. - Earn independent references. Listings in reputable directories, mentions in industry publications and genuine reviews raise Citation Potential and Web Authority more than anything you can do on your own site.
- Add an llms.txt if it helps your audience. It is optional and not used by Google, but it is cheap to publish. Build one with the generator and validate it with the llms.txt checker.
Then run the GEO score check again and compare dimension by dimension. Technical and content scores update as soon as your changes are live. Research based dimensions move as independent sources accumulate.
Frequently asked questions
How is the GEO score calculated?
It is the weighted average of six dimensions: Technical AI Readiness 20%, Content and Answerability 20%, Entity Clarity 15%, Citation and Source Potential 15%, Web Authority 15% and AI Visibility Evidence 15%, calculated only over the dimensions that could be measured.
Is a GEO score the same as an AI visibility score?
No. AI visibility is one of the six dimensions, and it is only scored when there is observed evidence of a site appearing in AI answers. The GEO score as a whole measures readiness.
How often should I check my GEO score?
After any significant change to a page, and otherwise about once a month. Compare the same URLs over time so changes are meaningful.
Is checking a GEO score free?
Yes. GEO Score Checker is free with no signup.
