How we build these

Every result shows the observed evidence and names its data source.
Official registries, your page's own HTML and headers, and public APIs only. No scraped search results, no fabricated metrics.
Useful before you sign up. Results are yours to copy, share, or pull from the free JSON API.
Every user-supplied URL is fetched through a hardened fetcher that refuses private networks, caps size and time, and never executes page scripts.

What is next

Search Console based reports (opportunity finder, content decay, cannibalization, CTR gaps) are the next build. They will use your own authorized data, read-only. Read more about the project.
