Now that Google is no longer publicly displaying Page Rank updates, how will this effect Moz's ability to calculate DA and PA?

Hi,

How much more important do you guys think that Moz's Page Authority and Domain Authority metrics are going to become now that Google has stopped giving people public access to a site or pages Page Rank?

And how accurate is PA and DA as a measurement in comparison to Page Rank..so for example if I was seeking a guestposting opportunity and saw a site as having a PR of 4....if I now looked to Moz's Page and Domain Authority metrics instead...would that still give me equivalent information on the strength of that domain and thus make a judgement on whether it will be a worthy site for a guestpost..

I guess what I am asking is, how close is now looking at Moz's metrics (ie. a third party company) to the info on PageRank that was being updated by Google themselves?

Also will the lack of updated public PR info from Google effect the ability for Moz to calculate PA and DA??

Look forward to your replies on this,

Domain Authority is Moz's calculated metric for how well a given domain is likely to rank in Google's search results. It is based off data from the Mozscape web index and includes link counts, MozRank and MozTrust scores, and dozens of other factors.

(source: http://moz.com/learn/seo/domain-authority)

At this point because its been atleast 6mo since last PR was updated, DA and PA is more accurate.

"would that still give me equivalent information on the strength of that domain and thus make a judgement on whether it will be a worthy site for a guestpost"

-In my opinion it has always given a more valid metric of authority and strength than PR.

The only downside and to comment to "how close is now looking at Moz's metrics (ie. a third party company) to the info on PageRank that was being updated by Google themselves"

Mozscape is not as large as the Google index, but it is pretty big and significant now.

Hope this helps

Hi thanks for your response,

But what I was getting at was, did DA and PA scores take publicly available Page Rank information into account when compiling the scores?

Because if they did, surely the scores will have changed/possibly becoming less accurate as Google has now made PageRank data private, so that is one less factor that Moz can include in their scores for DA and PA?

No they did not, Page Rank was not as great of a metric to track to begin with.

UPDATE I have no sure way of knowing if they did so in the past or starting out, maybe we will get an actual answer from a Moz staff if it was part of dozen of other factors. But its highly unlikely.

Okay thank you.

I final question, in context of an example.

So based on the above, I would assume that, say someone was seeking a relevant guest post opportunity for a high quality piece of content that they had written. Whereas in the past they may have looked at a domains/sites PageRank to determine the authority/strength of a site/page when deciding which sites to reach out with the content piece, would now looking at the DA and PA of the domain/page respectively, be equally effective in determining the quality of a site, to ascertain whether it is worth reaching out to...?

Thanks.

-Yea it will be more effective.

Hope this helps
