How to use this report

2 ways to use these figures
  • Price check. BV puts one new followed link from cromagnon.app at $8.83 (level C), priced on a blend of link types (A 3% · B 25% · C 71% · D 1%): $4.41 to an unrelated site (×0.5), $11 to a same-topic site (×1.25). A followed editorial link (level A) would be worth up to $39 before relevance. A quote far above $4.88 for a level C link pays for what BV does not measure. · Backlink value · what this means
  • Qualification and risk. Its Site Strength is 5 / 100; the link it usually gives is mostly level C — usually neutralised (a press-release, syndicated, profile or forum link). The spam score of its links is 21 (0–100, the linking pages' average), not cromagnon.app's own. · How BV is worked out · what this means

4 other publications on the server · 473 on the network

Its domain was registered in 2026.

4 other publications in the directory run on 216.198.79.1, which is common on shared hosting and not by itself evidence of common ownership. 473 publications are on the same hosting network (Amazon AWS, AS16509) — a cloud platform hosting millions of unrelated sites, so that is no sign of a connection.

Other publications on 216.198.79.1

At this size that is ordinary shared hosting, listed for completeness, not as a finding.

Amazon AWS is a cloud platform hosting millions of unrelated sites, so sharing it says nothing about who runs a site. The count is shown; the sites are not listed.

Limitations: what this report does not show

2 stated plainly
  • No link on this publication has been audited yet, so nothing here describes how its links behave.
  • cromagnon.app gives more than one kind of link (A 3% · B 25% · C 71% · D 1%), so BV prices a blend of them: an editorial link there would be worth $39 and a guest or sponsored one $20, before relevance.
