What is llms.txt?

llms.txt is a text file you add to your website that helps AI crawlers understand your business — like robots.txt but for large language models.

Why llms.txt Matters for Local Businesses

In 2026, 45% of consumers use AI search engines (ChatGPT, Claude, Gemini, Perplexity) to find local services — up from just 6% one year ago. Understanding llms.txt is essential because it directly affects whether AI recommends your business.

Google organic clicks have dropped 42% since AI Overviews launched. Businesses that ignore AI visibility signals are losing customers to competitors who optimize for them.
