Website authority checker
Authority score, referring domains, and the 12-month trend for any site - up to 10 domains at once. Twenty free domains a day. No signup.
What you get
- Authority score, 0-100
- Our link-graph score derived from Common Crawl data. Same scale every tool uses, our own label - we show you where it comes from.
- Bulk checks
- Paste up to 10 domains and compare them side by side in one go.
- Referring domains
- How many sites link to the domain - the quantity behind the score.
- 12-month trend
- Whether authority is climbing, flat, or slipping - not just today's number.
Authority tells you how hard a domain is to outrank. Pair it with the keyword evidence checker to find the keywords where sites weaker than yours are already on page 1 - then sign up to turn that into a full content plan.
Scores are computed from the Common Crawl web graph (Open PageRank data) and refresh monthly. This is our own 0-100 label, not any other vendor's metric.
