Domain Rating
90 daysA 0 to 100 score of how strong a domain’s backlink profile is, on a logarithmic scale, so the distance from 70 to 80 is far larger than from 10 to 20.

90 days, lower is betterPosition in the Tranco list, a research ranking of the million most popular domains averaged over thirty days so a single day’s traffic spike cannot move it.

How this page is made
Every number on this page is a measurement Domduck took itself or read from a public source, on a stated date. Nothing here is written by a language model. Where a value has not changed, no sentence is generated about it.
First reading . 8 sources, 116 days with at least one reading. The popularity rank comes from the Tranco list; the registration record from RDAP, which ICANN requires registries to publish. The certificate, the DNS records and the crawler policy are read by Domduck directly from github.com.
