There wasn't a simple way for website owners to know why AI search engines were ignoring their pages - or what to do about it.

We discovered this critical gap while managing our own websites. Pages that ranked well in Google were invisible in ChatGPT, Perplexity, and Google AI Overviews. The traffic was shifting — and there was no tool that could tell us why, or what to fix.

Traditional SEO tools weren't built for AI search. They checked meta tags and backlinks, but they didn't understand how large language models read, parse, and decide what to cite. The gap between "ranking in Google" and "being cited by AI" turned out to be a completely different problem.

This challenge inspired us to build PurpleLeaf — a platform that audits your entire website against the signals AI search engines actually use: structured data, LLM readability, Q&A blocks, content clarity, internal link health, and more. Not as a one-off check, but as continuous daily monitoring that alerts you the moment something slips.

What PurpleLeaf gives you

Every page on your site scored across 14 AI search signals — structured data, readability, Q&A, meta tags, link health, and more.
Not a flat checklist. Issues are prioritized so you always fix what will move your AI citations the most, first.
Every issue comes with a one-click fix — schema generation, Q&A blocks, content rewrites. No developer required.
PurpleLeaf re-scans your site automatically every day and notifies you when new AI visibility issues appear.

-- Our approach

AI search requires a different kind of audit

Google ranks pages. AI search engines cite sources. The criteria are fundamentally different - and PurpleLeaf is purpose-built for the new rules.

Built for how LLMs read

PurpleLeaf evaluates your content through the lens of large language models - not just crawlers. We check if your pages are structured in a way AI can extract, understand, and confidently cite.

14 signals, not 4

Structured data, alt text, Q&A blocks, LLMs.txt, internal link health, content clarity, and more - we audit the full picture of what it takes to be cited by ChatGPT, Perplexity, and AI Overviews.

Site-wide, page-by-page

One audit covers your entire website. We discover every page automatically via your sitemap and scan them all - so no invisibility problem slips through.
