SHORT ANSWER
Generative Engine Optimization (GEO) means preparing website content so language models — such as ChatGPT, Claude, Gemini or Perplexity — can correctly understand it, cite it and attribute the source. Key elements include: clear facts, short answers to specific questions, schema.org structured data, an accessible llms.txt file and permission for AI crawlers in robots.txt.
- GEO optimizes for citations in answers, SEO for clicks on search results.
- Models prefer content with clear numbers, dates and names.
- schema.org structured data helps machines attribute facts to entities.
- The llms.txt file is a concise website summary intended for models.
- Access for AI crawlers (GPTBot, ClaudeBot, PerplexityBot) is controlled in robots.txt.
How GEO differs from SEO
In traditional SEO, success means rankings and clicks. In GEO, success means a sentence about your company in an answer a model generates for someone who will never see a list of ten links.
The practical consequence: a model does not “browse” a website to get an impression. It looks for facts it can safely repeat. Marketing language like “a leader in innovative solutions” is useless because it cannot be cited without risk.
Write sentences that can be cut and pasted
The most effective format is a “short answer” block: one–two sentences containing a subject, an action and a number. A model can use them in full, without interpretation.
- Instead of “we deliver quickly” → “we deliver a working version in 3–7 business days”.
- Instead of “we have experience in retail” → “we implemented an inventory system for a retail store in 5 days”.
- Put every number in context: what, for whom, and in what timeframe.
A page structure machines understand
One H1 describing the topic, H2 headings phrased as user questions, paragraphs of 2–4 sentences and lists where facts can be counted. The same structure helps both a person on a phone and a parser.
Add structured data: Organization or ProfessionalService for the company, Article for the text, FAQPage for questions, BreadcrumbList for the hierarchy. These connect the text to an entity.
Let AI crawlers in — deliberately
If you block GPTBot, ClaudeBot or PerplexityBot in robots.txt, no amount of content optimization will help. It is a business decision: either you want to be cited or you protect your content from processing.
It is also worth providing an llms.txt file — a short, factual summary of the website with links to its most important pages. It is a low-cost investment that gives the model a clearer picture of your company.
How to check if it works
Ask models questions your website actually answers, and check whether your company name appears and whether the facts match what you publish. A discrepancy signals that the content is too generic or inconsistent across pages.
You cannot guarantee a presence in model answers. But you can remove all the technical reasons for your absence.
