Generative Engine Optimisation (GEO) Guide for 2025
How to rank in AI search engines like Gemini & ChatGPT
🤖 What Is Generative Engine Optimisation (GEO)?
Generative Engine Optimisation, or GEO, is the practice of optimising your content so that it performs well inside AI-driven search engines like Google AI Overviews, ChatGPT, Claude, and Perplexity.
These platforms are different from traditional search engines. Instead of returning a list of blue links, they generate answers to questions using content pulled from multiple sources – often without direct clicks to your site. GEO helps ensure your content is used, cited, and displayed in these AI-generated results.
🔍 How Does GEO Differ from Traditional SEO?
- SEO is about ranking on pages like Google Search or Bing through indexing and backlinks.
- GEO is about being used as a source inside AI answers or summaries, often without ranking at all.
This shift means your content has to be more accurate, clearly structured, and fact-rich – because AI tools need confidence to reference or summarise your pages.
🧠 Key Principles of GEO
- Authority & Trust: Use citations, link to reputable sources, and show expertise.
- Structured Content: Use bullet points, headings, and semantic HTML for easy parsing.
- Factual Accuracy: Keep content updated and correct to be selected by AI models.
- Direct Answers: Write like you’re answering a question – because AI is looking for answers.
- Entities & Context: Cover related topics thoroughly to help AI understand your niche.

⚙️ How to Optimise for Each GEO Platform
Google AI Overviews
According to Google’s Gary Illyes, showing up in AI Overviews doesn’t require anything special – just standard SEO best practices. That tracks logically: for Google to feature your content in AI Overviews, it first needs to crawl it with Googlebot and index it through the usual Google Search process.
The way content is discovered, understood, and ranked by Google Search also applies to AI Overviews and Google’s AI Mode. In fact, AI Overviews likely draw from many of the same ranking signals already used in traditional search.
In short: if you want to appear in AI Overviews, focus on doing good SEO as you normally would. Additionally, we suggest you also:
- Answer common questions clearly and directly
- Use proper H tags and structured layout
- Make use of schema markup to help define your content
ChatGPT (with browsing)
- Use factual, link-supported statements
- Break content into digestible sections with bullets
- Offer unique insights or useful summaries
Claude AI
- Claude values clarity and completeness
- Provide downloadable documents and high-quality HTML for analysis

- Ensure your site is indexable and has crawlable content
- Include sources and citations in your writing
- Use original, factual content that stands out
