A 0–100 metric that estimates the strength of a domain’s backlink profile relative to all known domains on the web. Higher generally means more (and stronger) referring domains.
Paste any domain (with or without https://) and submit. If it’s in our tracked database, you’ll get 7d and 30d deltas plus a public profile link.
Tracked domains in SEOlvl refresh daily at 02:00 UTC. Live lookups are fetched on demand against the underlying authority data source.
No — different vendors use proprietary models. Numbers move together directionally but aren’t identical. Always compare a domain against itself over time, not vendor-to-vendor.
