If you have run a WebSEO Auditor report recently, you have probably noticed a score labelled GEO alongside the familiar Performance, SEO, Accessibility, and Best Practices scores. Most people click past it. That is a mistake.
GEO stands for Generative Engine Optimisation. Your GEO score measures how well your website is set up to be discovered, cited, and recommended by AI-powered search engines — tools like ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot.

Why Traditional SEO Is No Longer Enough
Traditional SEO is built around one question: can Googlebot crawl and understand your pages? That is still important. But AI-powered search engines work differently.
When someone asks ChatGPT "what is the best SEO audit tool for agencies", ChatGPT does not run a traditional keyword search. It draws on everything it has been trained on, supplemented by real-time retrieval. It is looking for sources it can confidently cite — sources with clear authority signals, structured data, and machine-readable content.
If your website does not speak this language, it will not be cited. And if it is not cited, it does not exist in that conversation.
This is the gap that GEO optimisation addresses.
What Does a GEO Score Actually Measure?
A GEO score analyses several signals across your website. The key categories are:
1. AI crawler accessibility
Are the major AI crawlers allowed to access your site? Many websites inadvertently block GPTBot, ClaudeBot, PerplexityBot, or Bytespider through their robots.txt configuration. If these crawlers cannot read your pages, they cannot learn from them.
2. llms.txt presence and quality
The llms.txt file (analogous to robots.txt but for language models) tells AI systems what your site is about, which pages matter most, and how you want to be represented. A well-written llms.txt significantly increases the chance that AI tools use your site as a source.
3. Structured data (schema markup)
AI systems parse structured data to understand context. A page with Article, FAQPage, Product, or Organization schema gives an AI a much cleaner picture of what the page is about compared to reading raw HTML. Structured data is essentially a translation layer between your content and machine understanding.
4. Entity clarity
Do your pages clearly state who you are, what you do, and who you do it for? Vague, generic content scores poorly because AI systems cannot confidently make claims based on it. Specific, well-attributed content scores well.
5. Content freshness signals
AI systems favour content with clear publication and update dates. Articles with datePublished and dateModified schema are more trustworthy sources than undated pages.
6. Internal authority signals
Does your site link clearly between related topics? AI systems follow semantic connections. A site with strong topical depth — multiple related pages that reference each other — signals expertise in a way that isolated pages cannot.
How GEO Differs from Traditional SEO
| Factor | Traditional SEO | GEO |
|---|---|---|
| Primary audience | Googlebot | GPTBot, ClaudeBot, PerplexityBot |
| Key signal | Backlinks, keywords, page speed | Entity clarity, structured data, llms.txt |
| Goal | Rank on page 1 | Be cited in AI-generated answers |
| Content format | Keyword-optimised text | Clear, attributable, structured information |
| Result | Clicks from SERP | Mentions/citations in AI responses |
These two disciplines overlap significantly — good SEO helps GEO, and vice versa — but they are not identical. A site can rank well in traditional search while scoring poorly in GEO, particularly if it lacks structured data or blocks AI crawlers.
What Is a Good GEO Score?
GEO scores in WebSEO Auditor run from 0 to 100, using the same scale as the other audit categories:
- 90-100: Excellent. Your site is well-configured for AI discovery across all key dimensions.
- 70-89: Good, with room to improve. Typically missing one or two key elements such as llms.txt or full schema coverage.
- 50-69: Fair. Several gaps that limit AI visibility. Common at this level: AI crawlers blocked in robots.txt, missing structured data on key pages.
- Below 50: Poor. Significant configuration issues that make the site largely invisible to AI search tools.
The average score across sites audited in our platform in early 2026 sits around 41. Most websites have not yet addressed GEO optimisation at all.
The Five Highest-Impact GEO Improvements
If you are looking at a low GEO score and want to move it quickly, focus on these five areas in order:
1. Unblock AI crawlers in robots.txt
Check your robots.txt file. If you see User-agent: * with a Disallow: / or specific blocks that affect AI crawlers, add explicit Allow rules for the major bots:
User-agent: GPTBot
Allow: /
User-agent: ClaudeBot
Allow: /
User-agent: PerplexityBot
Allow: /
User-agent: Google-Extended
Allow: /
This is the fastest fix and has immediate effect once crawlers revisit your site.
2. Create an llms.txt file
Place a plain text file at yourdomain.com/llms.txt. At minimum it should include a one-paragraph description of your business, your target audience, and links to your most important pages. More detail is better.
See the llms.txt specification at llmstxt.org for the recommended format.
3. Add Article or BlogPosting schema to all blog posts
Every blog post should have BlogPosting schema including headline, description, author, datePublished, dateModified, image, and publisher. This transforms your content from anonymous HTML into attributed, dateable, citable information.
4. Add Organization schema to your homepage
Your homepage should clearly declare who you are with Organization schema. Include name, url, logo, description, and contactPoint. This is the foundation that makes everything else more trustworthy.
5. Add FAQPage schema where relevant
Pages with frequently asked questions — your pricing page, your help docs, your about page — should include FAQPage schema. AI systems frequently pull FAQ content to answer user questions directly.
GEO and Your Clients
If you are an SEO agency or freelancer using WebSEO Auditor to generate leads, the GEO score is a powerful sales tool. Most of your prospects have never heard of GEO optimisation. Showing them a score of 35 out of 100 — with a clear explanation of what it means and how to improve it — opens a conversation that your competitors are not having yet.
The agencies that learn to sell GEO services now will have a significant head start as AI-powered search continues to grow.
