What is llms.txt?
llms.txt is a plain text file at the root of your website that gives AI tools a short summary of your business and links to your most important pages, written in a simple format they can read quickly.
Does llms.txt help SEO?
Not for Google rankings. Google has said it doesn't use it. Some AI assistants and crawlers do read it, so it can help them describe your business accurately. It's free and quick, so it's worth adding. Just don't expect it to move your Google positions.
