AI answer engines increasingly respond to a question directly and cite a few sources. To be one of those sources, your content has to be discoverable and easy to extract. Here is how to improve your odds, step by step. For the bigger picture, start with what is GEO.
1. Let their crawlers in
Each engine uses named crawlers. In your robots.txt, allow the ones you want to appear in:
- ChatGPT / OpenAI: GPTBot, OAI-SearchBot, ChatGPT-User
- Perplexity: PerplexityBot, Perplexity-User
- Google AI Overviews: Googlebot (the normal one) plus Google-Extended to permit generative use
- Claude: ClaudeBot, Claude-Web, anthropic-ai
If these are disallowed, you cannot be cited by that engine, full stop.
2. Server-render your content
Most AI crawlers do not execute JavaScript. Open your page source (Ctrl+U) and confirm your main headings and copy are present in the raw HTML. If the page is blank without JavaScript, the crawler sees a blank page.
3. Write in a question-and-answer shape
Engines quote passages that cleanly answer a question. Use descriptive H2/H3 headings phrased the way people ask, follow each with a concise 2-3 sentence answer, then add detail. Bullet lists and tables for steps, specs, and comparisons are especially easy to lift.
4. Add structured data and an FAQ
Mark up your organization with Organization schema and your Q&A sections with FAQPage schema. This helps engines identify your brand and extract facts with confidence.
5. Publish an llms.txt
An llms.txt file gives LLMs a clean, curated map of your most important pages. It is low effort and forward-looking. See what is llms.txt and how to create one.
6. Earn authority
Citations and mentions from credible sites still matter. Listings, a real social presence, and genuine coverage all help an engine trust you enough to quote you.
7. Keep facts accurate and current
Answer engines favor content that is specific and up to date. Put clear dates on time-sensitive pages and revise them when things change.
A note on how the engines differ
Google AI Overviews draws largely from Google's own index, so being indexed and doing classic SEO well is the prerequisite. Perplexity and ChatGPT's search features run their own crawlers and also read the live web, so allowing their bots and being server-rendered matters most there.
