BDR is our 0–100 score for backlink strength. It rolls up the quality of inbound links a site earns from high-authority sources, with a strong penalty for sites that lean on low-quality referral networks. Use it to filter prospects and grade your own backlink profile.
BDR is a 0–100 score that estimates how authoritative a domain is, weighted toward backlink strength from high-authority sites. We compute it independently, no third-party DR provider, using our own crawl of the public web. A higher BDR means more, better, and more stable inbound links.
BDR is a roll-up of five sub-signals. We expose each one in the breakdown so you can see why a domain scored the way it did, and which lever would move it most.
Quality-weighted strength of inbound links. Heavily favors editorial coverage from high-authority sites.
Counts distinct domains linking in. Punishes single-source link farming and outsized footer links.
Share of inbound links from real editorial sources versus directories, comment spam, and PBN footprints.
Percentage of inbound links that have stayed live over 12 months. A signal of genuine, durable coverage.
Inverse signal: heavy broken-link rot drags BDR down. Healthier link graphs score higher.
