Bulk Domain Screener

Every other tool here looks at one domain. This one looks at your list. Paste up to 100 domains — an outreach shortlist, a vendor's promised "1,000 quality backlinks", a competitor's referring domains — and get domain rank, spam score and referring-domain counts side by side, each with a verdict and the reason behind it.

The four verdicts, and why

• pursue — ranked with a clean spam score; worth the full simulator treatment
• watch — some authority, but one signal is off; check it before spending time
• weak — no measurable authority behind the domain (rank 0 or missing)
• avoid — spam score in the toxic band; a link from here transfers the flag

How it stays cheap enough to be free

The screen uses the backlink database's bulk endpoints — ranks, spam scores and referring-domain counts for up to 1,000 targets per call — instead of per-domain lookups, so a 100-domain screen costs a fraction of one detailed profile. Results are cached per domain for a week, which is why repeat or overlapping lists return almost instantly.

What it deliberately does not know

A bulk call cannot tell you whether the engines cite a given source — that needs the citation index, which is built from observed AI answers. So the screener stops at authority and cleanliness, and hands the shortlist to the Link Value Simulator, which reads the citation evidence one domain at a time.
