When trying to build backlinks, of course some sites are much harder to get links on than others. I am trying to figure out which sites my time and effort is best spent trying to get a link on. I may view a site as important and high quality but Google may not. Which tools and metrics within MOZ should I look at to determine if a site is worth the effort to get a backlink from?
I'm sure "Domain Authority" is a factor. Which number makes it definitely worth pursuing?
Does inbound links and spam score count for anything?
Which metric is best to look at to figure out the most powerful backlink I can get?
