Domain Authority and Page authority for external links. What's the difference in value?

[isaac663]

Hi Guys.

I understand the difference between page authority and domain authority in terms of how likely that page is to rank.

But what about a links from a high DA site, but from a low PA page?

We’ve identified a client with extremely high DA (73/100), but their blog page has a PA of 1/100.  Would a link from this page be pretty much valueless due to the low PA?  Or would it still be quite strong as the DA is so high?

Perhaps you could point me to some good reading or Moz post on this topic?

Thanks guys.

Isaac.

Is a great question isaac633. In my opinion, I think that both are very important but If I could be linked from a page with PA 70/ DA 10 or other with PA 10/ DA 70, I would choose the second one with more DA. This was asked too here http://moz.com/community/q/da-vs-pa-when-building-links

Bye!

Hello Isaac,

I agree with Ruben,

PA can be the result of a new/unranked page or one that wasn't properly optimized, whereas DA is hard to argue with. It is a trusted source and that trust flows through the page by virtue of it coming from the same domain.

It could also mean that their link profile has targeted their home page (or others) instead of this blog post (or the blog in general). There can be many reasons for this, but in all likelihood this link will help you out.

Check out the reading Ruben provided you with - it will go into this with more detail. I'm around if you have follow-up questions.

Hope it turns out for you!
