Domain Authority and PageRank Aren't Meshing

[alankoen123]

I'm seeing a very large discrepancy between the domain authority for a site I'm tracking and the PageRank. According to PageRank Checker the PageRank is "0". According to Moz, the domain authority is 57 and page authority for the domain below is in the 32. The domain is http://bwellness.massagetherapy.com/ Open Site Explorer shows 2 linking domains -- both have D.A. scores of 13.

Please explain the discrepancy. Thanks in advance.

PageRank isn't updated from December 6, 2013 and won't be updated in future. Please don't rely on this metric anymore.

You can use Moz DA,PA, MozTrust, MozRank. You also can use Majestic CF, TF; also Ahrefs URL rating, domain rating. Because all of them are updated least monthly. But comparing them with 2 years old data (PR) isn't fair.

Thank you Peter. I used Majestic Site Explorer and it was far more useful than Moz Open Site Explorer:

At the very top of the results, it states:

Would you like to switch to the entire massagetherapy.com domain? There are 164,851 external backlinks.

If only Moz were to add this !!  It makes sense that this very small business is a subdomain of a much larger site and is thus inheriting the authority. The high Page Authority is still a bit baffling. Could be that the subdomain site is getting visits from domain level searches and links from other pages within the domain. Thanks!

If you have idea for Moz improvements - write them to help@moz.com

I use all three products and each of them have some pros and some cons. If your situation you have huge domain with many subdomains. And you can't see whole domain. So you can suggest this to them.

Wow, you have a LOT of spam in your backlinks. Have you done a disavow or had a penalty with this site?

I think Peter adequately answered your question - PageRank isn't an accurate measure of anything - but keep in mind that DA & PA can be manipulated as well ... with a backlink profile like yours you will probably see a higher DA than you "deserve" because DA doesn't really take spam into account nearly as much as Google does.
