Dir Bear Domain Index — Bear Rank for 1,000,000 domains

One row per domain. Bear Rank is a 0–100 quality score built from public signals: traffic rank (Tranco), link authority (Majestic referring subnets and IPs), an estimate of longevity and an estimate of safety. Weights are Popularity 30 %, Authority 30 %, Longevity 20 %, Safety 20 %. Tiers: grizzly ≥ 90, kodiak 75–89, polar 50–74, cub < 50.

This is the index used to label every document in the Dir Bear corpus (https://dirbear.com). It is published so you can filter or weight web text by source quality yourself.
