Website authority is a concept used to describe the "strength" of a given domain. While Google doesn't use a single "authority score" to rank websites, the SEO industry has developed several metrics to estimate how well a site might rank.
Our tool provides the three most respected authority metrics in the SEO industry:
Developed by Moz, DA predicts how well a website will rank on search engine result pages (SERPs). It ranges from 1 to 100.
DR shows the strength of a website's backlink profile compared to others in Ahrefs' database on a 100-point scale.
TF represents the quality of backlinks. It measures how "trustworthy" a site is based on the quality of sites linking to it.
Using Moz, Ahrefs, and Majestic metrics together gives you a more complete picture of a website's true standing than any single tool could.
No single tool sees the whole internet. By comparing metrics from Moz, Ahrefs, and Majestic, you get a complete, 360-degree view of any website's true authority.
High DR (quantity) but low TF (quality) can be a red flag for spammy backlink profiles.
Analyze your competitors' authority across multiple dimensions to find where you can realistically outrank them.
Authority is relative. A "good" score depends on your niche. Generally, new sites are 0-10, small niche sites 20-30, and high-authority industry leaders are 60+. Focus on being better than your direct search competitors.
All three are valuable. Ahrefs DR is great for estimating link popularity, Moz DA is widely used for general ranking potential, and Majestic TF is the gold standard for site trustworthiness. Together, they are most powerful.
The best way to improve authority is by earning high-quality backlinks from other reputable websites in your industry. Focus on creating link-worthy content and building relationships within your niche.
