As search behavior shifts toward conversational platforms and AI-driven environments, Litmus provides a dedicated solution to measure and optimize how visible your website is to major AI search engines like ChatGPT, Perplexity, and Google's AI Overviews.

This means you get the exact same score for the same input, every single time. Beyond scoring, Litmus provides actionable guidance by detailing precisely what needs to be fixed and how to fix it, empowering you to either resolve issues using AI or package the solutions to sell directly to clients.
