Duplicate & Thin Content Detector
Find the pages that say the same thing, and the ones that say nothing.
Crawls your site and compares what each page actually says — after subtracting the navigation, footer, and everything else repeated site-wide. That subtraction is the whole trick: compare raw text and a shared menu makes every page look identical, which is why naive checkers report entire sites as duplicates. What is left is each page’s own content, compared exactly rather than estimated. Groups of near-identical pages are flagged, and the ones with no canonical and no noindex are flagged harder, because there nothing tells Google which version is the original. Pages carrying almost no content of their own are listed separately.
Enter any address on your site — usually the homepage. The crawler follows your internal links, then compares what each page actually says once shared navigation and footers are discounted.
This takes a while — dozens of pages are fetched in a single run.
