GEO — Generative Engine Optimisation — is the discipline of making your website readable, citable, and trustworthy for AI search engines. If you have heard of SEO, think of GEO as its successor: instead of optimising for a list of ten blue links, you are optimising to appear in the one answer an AI tool gives when someone asks a question in your category.
The short answer
GEO is a set of technical and content practices that help AI tools like ChatGPT, Claude, Perplexity, and Google's AI Overviews understand, trust, and cite your website. Where SEO makes your page rank in search results, GEO makes your page get quoted in AI answers.
GEO is the practice of structuring your website so that AI language models can read it, understand it, and cite it as a trusted source.
Why AI search engines work differently from Google
Google returns a list of results. AI tools return a single synthesised answer. That is a fundamental shift in how discovery works online.
When someone types "best project management tools for small teams" into ChatGPT, the model does not return ten links. It reads its training data, checks live search results if it has web access, and produces one paragraph that names specific tools. If your product is not in that paragraph, you get zero traffic from that query — regardless of where you rank on Google.
AI tools do not rank pages. They read them the way a researcher would: looking for structured information, direct answers, credible signals, and clear entity definitions. Sites that are structured for human browsing but not machine reading are being skipped.
The six GEO signals AgentReady checks
After auditing thousands of websites, we have identified six categories that determine whether an AI tool can find, read, understand, and cite your site.
1. Product Data and Structured Feeds (25% of score)
This is the highest-weighted category because it is the primary signal AI tools use to understand what you sell. Schema.org markup for Product, Offer, and ItemList types tells AI exactly what your products are, what they cost, and whether they are in stock. Sites without this data cannot be accurately recommended for commercial queries.
2. Content and Answer Readiness (20%)
AI tools cite content that answers questions directly. Pages structured as walls of marketing copy get passed over. Pages that lead with a clear one-sentence answer, use question-based headings, and include FAQPage schema are 2.5x more likely to appear in AI-generated answers.
3. Trust and Authority (15%)
Reviews, credentials, Organisation schema, and brand mentions signal to AI tools that your site is a credible source. AI tools weight trusted sources higher. A site with no trust signals gets less citation weight, even if its content is accurate.
4. Conversion and Action Readiness (15%)
AI agents are increasingly taking actions on behalf of users — booking appointments, adding items to carts, making enquiries. Sites with clear pricing, visible CTAs, and accessible contact options score higher because AI tools can recommend them confidently.
5. AI Discovery and Integration (15%)
This covers the technical signals that specifically target AI crawlers: llms.txt at your domain root, FAQPage schema, entity clarity across pages, and machine-readable navigation. These signals tell AI crawlers what your site covers before they read a word of content.
6. Technical Crawlability and Indexing (10%)
If AI crawlers are blocked by your robots.txt, none of the other optimisations matter. This category checks that GPTBot, ClaudeBot, PerplexityBot, and Google-Extended have explicit access, that your sitemap is current, and that your key pages return HTTP 200 with no redirect chains.
GEO vs SEO: what each one does
| Signal | SEO Focus | GEO Focus |
|---|---|---|
| Content structure | Keyword density, readability | Direct-answer format, question headings |
| Technical setup | Page speed, Core Web Vitals | robots.txt AI permissions, llms.txt |
| Structured data | Rich snippets (nice to have) | Schema.org (essential) |
| Authority signals | Backlinks, domain authority | Organisation schema, trust signals |
| Discovery file | sitemap.xml | llms.txt + sitemap.xml |
| Primary target | Googlebot | GPTBot, ClaudeBot, PerplexityBot |
The two disciplines have limited overlap. You need both. Ignoring GEO does not affect your Google rankings. But it does mean you are invisible to the AI tools that are now handling a growing share of discovery queries.
How to start with GEO today
The fastest path to GEO improvements follows a specific order. Start with Technical Crawlability (Category 6) because blocked AI crawlers make everything else irrelevant. Then move to AI Discovery (Category 5) to add llms.txt and check entity clarity. Then tackle Structured Data (Category 1) for the biggest visibility gains.
Within each category, every fix in an AgentReady report includes a ready-to-paste code block. You do not need a developer for most of them.
