I recently discovered that Google has updated its guidelines on optimizing for AI Search, and they’ve made it clear that LLMS.txt files on your site won’t impact your search rankings. It’s a relief to know that Google Search doesn’t actually utilize these files.
The portion of Google’s update that caught my attention explains that there’s no need to create new machine-readable files, such as AI text or Markdown files, to appear in Google Search, even with generative AI. Google will still discover, crawl, and index a variety of files, but these won’t receive special treatment.
Google also mentioned that maintaining LLMS.txt files for other services is perfectly fine and won’t influence your visibility in Google Search. In short, these files neither harm nor enhance your standing in search rankings.
For those interested, here is a valuable section screenshot along with more resources on the topic:

Expressing why I care about this, there’s ongoing confusion around how Google handles such files. Remember, having them on your site won’t help but also won’t hurt your SEO efforts.
