Welcome to the Q&A Forum

Hi there, While looking at metrics like this is important, you're approaching modern link development in a slightly misguided, old-fashioned way. This is the way we used to link about link dev three or four years ago. For one, there is little use finding an older article (anything published more than a few days or weeks ago) and trying to get a link on it. This was a very popular, effective tactic up until about 2010. However, figuring out if a link was included as an original citation or added after the fact is incredibly easy. Thus, it's easy to discount links-added-later, and you can be fairly sure that Google is suspicious of these links given how popular this link development tactic was pre-2010. If a site has good Moz metics (DA, etc.) and no or very low toolbar PR, this can be an indication that Google finds something wrong with the site... but toolbar PR is a relatively outdated metric now, so take its figures fairly lightly. If you can potentially get a link from a site, look at all of these metrics and then look at both the backlink profile of the potential linking site and which other sites it links out to. Does it look like it sells links to unrelated, spammy websites / industries? Don't go for a link with them. Do they advertise a text-link service where anyone can buy a link on their site? Definitely stay away. If you come across a less-popular site in your niche with original, quality content, don't turn a link down on that site because it has low metrics. "2. If a site is a PR2 DA 30/ PA 32 with 14 root domains, 250 total links.... Would a link like this give me any benefit or should I skip links like this? Why?" To answer this, you're going to need to look further than these metrics. Those numbers are good enough that if the site is otherwise a good match for yours, the link could be worthwhile.
