DA vs PA when building links

[studio35design]

When building links to your site from other sites, what is more important or what weights more heavily?

Say a site has a DA of 20 and PA of 34 for that page I want a link from. Say another site has the revese, a DA of 34 and a PA of 20. All things being equal, which site's link to me would be better?

The one with a higher DA or the one with a higher PA for the on the specific page I would get a link?

In my experience, I look at some statistics per page of the DA + PA because I believe that both matter in terms of how they rank.

Hi Ruben Nunez

DA is more important then PA so you can consider more then 25 DA website at least for any kind of link building.

If websites have good DA will be trusted as per Google norms.

I do not believe that this is true.  I think that DA and "trusted by Google" are very different things.  I think that some sites with very high DA are not trusted by google and penalized by google.

I think that links to or from some high DA websites could be harmful to your rankings.

I would like to hear Moz or Google respond to this.

EGOL is essentially correct - DA and PA are measures of ranking power, essentially (they both factor in multiple variables), but we don't currently model things like the likelihood of a link to be spammy - although we're working on that. So, it is definitely possible for a site to have high authority in theory but devalued by Google in practice.

It also depends on whether you mean "trust" in a broad sense or specifically something like TrustRank. Our MozTrust metric was intended to approximate TrustRank, which essentially measure how far a site is from a seed set of trusted sites. That's a way we believe Google has quantified "trust" in the past. I don't believe that PA/DA factor in MozTrust, but I'm not entirely sure on that one.

In terms of link value, DA and PA can both matter, and it depends a bit on the situation - even both metrics are only a small piece of the puzzle. If the numbers are similar and low (like 20/34 or 34/20), I wouldn't obsess about it. It's when they differ quite a bit that you might want to consider both. A weak page on a very strong domain or a very strong page on a weak domain both have potential value as link sources.
