DA vs PA when building links
-
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?

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.

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.

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.

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.

Link building with PDFs
I created a manual for a popular piece of equipment and placed it, as a PDF-file, on my website. The PDF contains a clickable link to the root domain of my website. Other websites have downloaded the PDF and put it on their own website, hosting it themselves. Since Google indexes PDFs, does the link in the PDF count as a regular 'link' from an external website, and does it have comparable value? Can't find any thoughts or studies about this anywhere.

Link building for a product review site
I'm doing SEO for a product review website, and I'm curious what link building opportunities are best for this category. Assume only the following: The website is basically a blog Most of the articles are reviews on cosmetic products, though there are also articles regarding news, product roundups, tips&tricks and similar content The website is in a local, non-english language Disregarding low-value opportunities such as directories, what kind of websites should I aim for outreach purposes? So far, I'm thinking the following: Product manufacturers (very low success chance, as the review site is fairly new and in a localized language) E-commerce sites selling the products (average to low success chance, since a lot of them use CMSes that might not allow integration of a review) Other cosmetic blogs, particularly for guest blogging (average to low success chance, since the website is fairly new) Any ideas would be appreciated, thanks!

Is it important to have a geo modifier for local SEO link building?
If anyone here is familiar with local SEO, you may have noticed that there are different local results for: "city + Keyword" and just the "keyword". When building links will you end up targeting both with a geo modifier in the link, or is it beneficial to build links without the geo modifer for the keyword?

Building Links to Exact Match Domains
What are the pros and cons having exact match domain and how can you create a brand name and build backlinks? Say we have a domain personalizedbirthdaygifts.com We are quite stuck with what anchor text we need to use and how do we vary it? I've heard that we have to stay away from using commercial keywords as anchor text heavily. We have to also use our brand name. And here we get stuck as we don't have a brand name. In this case Our brand name should be personalized birthday gifts but this is also commercial keyword. I have seen before similar websites droped from ranking because they have commercial keywords in their domain and most of their backlink anchor texts are commercial. If I had a website called twentyfive.com selling birthday gifts it would be a lot easier. But when you have a website personalizedbirthdaygifts.com and trying to rank for personalized birthday gifts and birthday gifts it's tough. OR isn't it? I hope I explained it well and didn't confuse anybody... Thanks
