The idea spread fast. The number of sites with one grew from 4,088 to 36,120 between June 2025 and May 2026, according to Originality.ai’s tracking (PPC Land).
There’s little sign that anyone reads them. In Ahrefs’ server logs for 137,000 sites, 97% of llms.txt files got no requests at all in May 2026. Google says the file “won’t negatively or positively impact your visibility or rankings” in search (PPC Land). Its guide to AI features adds: “You don’t need to create new machine readable files, AI text files, or markup” (Google Search Central).
We publish one anyway, as a plain summary of what outshone is. It costs nothing to keep. We just don’t pretend it’s a way to get named.
