Importance
llms.txt acts as a sitemap for LLMs. Without one, the LLM answers from whatever pages it has indexed, which may not be the publisher's canonical pages.
In commerce
In the Logitech episode, Deepa Shekhar, Director of E-commerce Technologies, identified llms.txt as one of the methodologies Logitech’s technology team used to make brand content discoverable by LLMs:
“There are methodologies like llms.txt, which serve as a site map on the website, which instructs LLMs that this is the navigation part to find this kind of content.”
— Deepa Shekhar, Director of E-commerce Technologies, Logitech
She described it as one element of a broader effort: marketers writing content around the questions customers were asking LLMs, technology teams publishing that content in structured formats LLMs could understand. The combined work contributed to Logitech earning the “Growth Engine” award in Semrush’s 2025 AI Visibility Awards for Consumer Electronics.
