Optimixed Overview
Optimixed's original report on this story.
SE Ranking conducted research across 300,000 domains to assess LLMs.txt adoption and its impact on AI citations. The study found that LLMs.txt adoption remains low and does not appear to meaningfully influence whether AI models cite or reference a site's content, suggesting the file format has not yet become a significant factor in generative engine optimization.
