Technical SEO for AI: Robots.txt, GPTBot & llms.txt Explained | 3.4. AEO Course by Ahrefs

Technical SEO might be the reason AI cannot see your site, and in minutes you will learn if robots.txt, GPTBot, and llms.txt are quietly blocking you.

We start with robots.txt for AI, because it is not just Googlebot anymore. You will see how to spot and fix rules that block GPTBot, OAI-SearchBot, ClaudeBot, and Google-Extended, plus a heads up on Cloudflare’s default setting that can silently add AI blocks. We also show how to use Ahrefs’ Site Audit to flag AI crawler issues fast. You will hear where llms.txt fits in today, why it is not a priority, and how to think about it alongside robots.txt. Then we get practical with rendering and speed. If your content relies on JavaScript, ChatGPT’s crawler will not see it, so we cover a quick no-JS test and why server-side rendering is the fix. We touch on page speed for AI retrieval too, since slow pages can get skipped while systems fetch and chunk in real time. From there, you will learn how clean HTML structure, clear headings, and atomic sections help AI parse your pages, and where schema markup fits for AEO. Finally, we tackle AI-hallucinated URLs, how to find AI referrer traffic that hits 404s, and the simple redirect play that turns lost clicks into engaged visits. If AI visibility matters to your business, do these checks before the next crawl. Watch now to make sure AI can find you, understand you, and promote you.
