Generative AI platforms like ChatGPT, Claude, Perplexity, and Gemini are changing how people find information online.
Instead of just ranking pages like traditional search engines, these AI assistants often cite and summarize content directly.
That means if your website isn’t optimized for AI search, you could be missing out on valuable visibility.
Checking your GEO (Generative Engine Optimization) score helps you understand how well your content is structured, credible, and readable for AI platforms.
It’s the easiest way to see whether your pages are being cited and how you can improve.
