Does an llms.txt file improve AI visibility? What the evidence says
Google says it ignores llms.txt and Ahrefs found 97% of files got no requests in a month. What the evidence says, and why we publish one anyway.
Ben Rosenbaum. Technical. Published .
An llms.txt file is a plain-text summary of a website, placed at /llms.txt, written for large language models to read. The idea, proposed at llmstxt.org, spread quickly, and it is sometimes presented as an AI visibility fix.
So far, there’s no evidence it does.
What the evidence shows
Google says it ignores it. Google’s guidance on AI features and your website is direct: you do not need new machine-readable files, AI text files or special markup to appear in Google Search, including its AI features, and Google Search ignores llms.txt.
Almost nothing requests it. Ahrefs studied llms.txt files across a large set of sites and found that 97% of published files received no requests in a month.
No link to citations. SE Ranking’s analysis of around 300,000 domains found no clear relationship between having an llms.txt file and being cited by AI.
That could change if the AI companies start using it. But today there is nothing to suggest that adding one will make an AI assistant more likely to recommend your business.
So why does ansoar.io publish one?
We do publish an llms.txt file. It is a plain summary of what Ansoar does, which pages exist and how to contact us. It takes minutes to maintain, does no harm, and if a tool does read it, it gets an accurate description.
What we will not do is tell a customer they need one, or present a missing llms.txt as a problem. Ansoar does not flag it in Crawlability or Page Readiness.
What actually tends to come up in AI answers
If you are looking for work that is better supported by evidence, start with the basics:
- Make sure AI search crawlers can reach your pages. See which AI crawlers affect AI search.
- Answer the decision a customer is making on your own pages. In BrightLocal’s study of nearly two million AI citations, around 93% of cited domains were individual business websites.
- Keep your listings and reviews in order. The same BrightLocal study found Google Business Profile accounted for 28.5% of citations, and Seer Interactive found brands with an active Trustpilot profile were cited far more often than brands without one.
These are observed patterns across many businesses, not guarantees. The way to know what matters in your market is to measure your own answers, which is what Ansoar is for.
