How many domains can I compare?

Two to five at a time. Each domain takes about a dozen lookups across public sources, so larger batches would be slow and impolite to those services.

Who “leads” a signal?

The domain with the highest raw value for that signal, like the best Tranco rank or the most Wikipedia links. Ties are shared.

Why is a value missing?

Some sources rate-limit or don’t cover every domain: Tranco only ranks the top 1M, and some country domains (.de, .io, .me) publish no registration date.

Yes. Every tool is free with no signup.

Do you store what I enter?

Browser tools never leave your device. Live tools fetch the URL you enter and don’t save the result.

How is this different from the site audit?

This tool checks one thing in depth. The site audit checks everything at once and scores SEO, AI Search and Agent Readiness.

Why it matters

See why a rival gets cited

Two sites with the same DR can look very different once you add entity presence and community mentions.

Mentions beat links for AI

Ahrefs found branded web mentions correlated about twice as strongly with AI Overview visibility as DR did.

Find the cheapest gap

A missing Wikidata item or a blocked AI search bot is quicker to fix than 500 new backlinks.
