What Does a GEO Score Mean?
A GEO score is a composite measure of how well your website is positioned to appear as a cited source in AI-generated search answers. Here is exactly what it measures, how it is calculated, and what a given score means for your actual AI search performance.
A GEO score is a composite 0-100 measure of AI search visibility calculated across five signal categories, where scores below 40 indicate near-total invisibility and scores above 85 indicate full readiness for AI citation across ChatGPT, Perplexity, and Google AI Overviews.
How a GEO score is calculated
A GEO score is a weighted composite of eight category scores, each reflecting a different aspect of AI search visibility. SearchScore evaluates over 80 individual signals across these eight categories.
| Category | What it measures | Weight |
|---|---|---|
| AI Visibility | Can AI crawlers access and understand your site? | High |
| Brand Authority | External credibility and entity verification signals | High |
| On-Page Structure | Schema markup completeness and correctness | High |
| Content Quality | Author credentials, content quality, expertise signals | Medium |
| Technical Platform | Speed, HTTPS, semantic HTML, crawlability | Medium |
| User Experience | Engine-specific signals and emerging standards | Medium |
What each score tier means
0-39: Invisible
Critical barriers to AI citation are present. Most commonly: AI crawlers are blocked in robots.txt, making all other GEO work irrelevant. Websites in this tier are effectively invisible to most AI search engines. Immediate technical fixes are required before any other GEO work will have impact.
51-70: Emerging
The most common tier - representing the majority of the 650,000+ websites we have audited. Basic access is possible, but significant gaps remain in structured data, brand authority or content signals. Targeted improvements can move a website out of Emerging fairly quickly.
60-74: Strong
Above average AI search visibility. The website has solid foundations - AI crawlers can access content, core schema is in place, and brand signals are present. Improvements in this tier typically come from content optimisation, authority building and more complete structured data coverage.
75-84: Advanced
Well-optimised for AI search. The website is performing strongly across most categories and is regularly cited in AI answers on its key topics. Improvements here are refinements - addressing the remaining gaps in lower-scoring categories.
85+: AI-Ready
The top 4% of websites. Strong across all eight categories. Consistently appears as a cited source in AI answers for relevant queries. This tier represents a durable competitive advantage in AI search visibility.
Reading category scores
The overall score is a starting point. The category breakdown tells you where to focus. A website scoring 65 overall but 20 on On-Page Structure has a clear, high-impact priority. A website scoring 65 with balanced scores across all categories needs broader, incremental improvement.
In our data, the most common low-scoring category is On-Page Structure - found on 81% of audited websites. The second most common is AI Visibility - found on 73%. Fixing either can significantly move an overall score.

Frequently Asked Questions
What is a GEO score?
A GEO score is a numeric score from 0 to 100 measuring a website's AI search visibility across eight categories: AI citability, brand authority, structured data, EEAT content signals, technical platform health, platform-specific optimisation, topical authority, and AI platform readiness. A higher score indicates stronger positioning to appear as a cited source in AI-generated answers.
What is a good GEO score?
Based on analysis of over 12,000 websites, scores of 70 or above indicate strong AI search visibility. Scores of 85 or above represent the top 4% (AI-Ready tier). The average score is 52. Any score below 40 indicates significant barriers to AI citation that should be addressed urgently.
Can a website have a high GEO score but low Google rankings?
Yes. GEO and SEO are related but distinct. A website could have strong technical GEO signals (AI crawler access, schema, llms.txt) with modest Google rankings if its backlink profile is thin. Conversely, a high Google-ranking website could have a low GEO score if it blocks AI crawlers or lacks structured data.
