Domain Authority Checker

Domain authority is a score that estimates how strong a domain is in search engines, based on signals like backlinks, age, and organic traffic. Different tools use their own scales. This tool uses the Open Page Rank score on a zero to ten scale, which is a free public alternative to the old Google PageRank.

SEOs use authority as a quick gauge before investing in a backlink, buying a domain, or competing on a keyword. A higher score usually means a stronger backlink profile and longer history. It is not a direct Google ranking factor, but it correlates with the things Google does reward.

1. A score of zero to two means almost no authority, common for new or low traffic sites.
2. Three to five is healthy for established small business sites.
3. Six to seven is solid for niche authority sites.
4. Eight and above is reserved for major news, government, and global brands.

Use it as a relative comparison, not an absolute truth. Comparing five competitors using the same tool is useful. Comparing scores across different tools rarely makes sense because each runs different math.
