— AEO QUESTIONS

What is llms.txt, and does anyone actually use it?

A proposed file that summarizes a site for AI agents. The current reality: Google has explicitly stated it doesn't use it for Search or AI Overviews, and no major lab has confirmed it as a signal in their search products; it mainly makes sense for technical documentation aimed at agents. It doesn't hurt, but it isn't the main lever.

Below: how to check whether the AI bots actually visit your site, what sitemap and robots.txt still do, and whether you need special technology.

How do I check whether AI bots are visiting my site?

In your server logs or your CDN (Cloudflare has dedicated AI crawler reports): look for user agents like GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot, Google-Extended, then see which pages they read and how often. It's the most concrete sign of AI's interest in your site.

What role do the sitemap and robots.txt still play?

They remain the basic contract with every bot: the sitemap speeds up discovery of new pages, robots.txt decides who gets in — including AI bots, with separate directives for training and for search. Check that you're not accidentally blocking them with old rules.

Do I need a new site or special technology for AEO?

Almost never: an indexable, fast site with clean HTML and structured data covers the technical side. What actually makes the difference is topical coverage — answering the questions buyers ask — and the ecosystem of external sources, not the technical platform.
