Litmus

什么是 Litmus？

The Lighthouse for AI search. Litmus scores how visible your site is to ChatGPT, Perplexity and AI Overviews. Unlike tools that just ask an LLM to grade your site (different answer every time you ask), Litmus is fully rule based and deterministic, same input, same score, always. It also tells you exactly what to fix and how to fix it. You can fix it with AI or sell the solution to clients.
