Times in SEO are changing and Google no longer values Page Rank as much as it used to. In fact, page rank has not been updated since 2013, and the page rank toolbar, in over a year. Page rank is simply no longer an accurate judgement of link authority anymore. So then, what is? The standard in 2015 is now the Moz “Domain Authority”.
Moz DA is similar to PR in that it shows the “link juice” of a site by displaying a number. The difference is the PR goes 0 through 10 and DA goes 0-100.
Domain Authority is a score (on a 100-point scale) developed by Moz that predicts how well a website will rank on search engines. Use Domain Authority when comparing one site to another or tracking the “strength” of your website over time. This metric is calculated by combining all other Moz link metrics (linking root domains, number of total links, MozRank, MozTrust, etc.) into a single score.
Here is an estimate in how domain authority compares to PR. This isn’t exact (since algorithms and signals fluctuate), but it can at least give you a guiding reference.
- Moz Domain Authority 15-20 (Small power, PR1 or PR2)
- Moz Domain Authority 20-30 (Medium power, PR2 or PR3)
- Moz Domain Authority 30+ (Large power, PR3 or PR4+)
To determine Domain Authority, Moz employs machine learning against Google’s algorithm to best model how search engine results are generated. Over 40 signals are included in this calculation. This means your website’s Domain Authority score will often fluctuate. For this reason, it’s best to use Domain Authority as a competitive metric against other sites as opposed to a historic measure of your internal SEO efforts.Check Domain Authority Here
