PR2 vs Page Authority 65

[Ebtec]

Looking at a website that has a Google Toolbar rank of 2. Moz Authority is 65. Why would there be such a huge difference? Site has been around since 2000 but has not been updated. Mosst of the links are from 3000 links all owned by the same person.

Hello,

The Google PR has been deprecated, the time in time it is updated by Google, when I'm looking for good links, I prefer to see other indicators in this order:

1. Google PR (only if it is PR=0) - site potentially penalized.

2. Domain Authority / Page authority.

3. Alexa Rank (give an idea about the site traffic and its authority).

I hope it helps

Hi Ebetc,

Mostly look at the frequency that both metrics gets updated. PageRank hasn't been updated for months and before that update not for over a year. Moz's metrics have been updated on a monthly basis and are a bit more accurate and compare it most cases quite good to a PageRank equivalent.

Moz currently doesn't have any type of spam score when looking at the DA of a site, so that could be another factor -- Google has dropped the toolbar PR because of spam, yet we don't take that into account.

[Ebtec]

So since the Da is so different that the Toolbar PR you are assuming it is some type of spam penalty? Perhaps because almost all of the inbound links are from the same domain owner?

I'm not assuming anything, but wanted to just make you aware of how we calculate things.

Ok...let me rephrase...

In general what  reasons do you usually see for such a wide discrepancy from Da to PR?

Thanks for your help.

With this type of discrepancy, that's often the case. Either the site has been penalized or the linking sites have been devalued in some way (say, a link network). DA/PA basically model the raw strength of the link profile, but they don't account for some quality factors.

Of course, that assumes the toolbar PR is up-to-date and accurate, which is a fairly big assumption these days, IMO.
