I'm doing some research at the moment and have found some niches/keywords. When looking at competitor's backlinks how many do you think is too many to bother with? Let's say someone has a site with 200 backlinks all PR 10 Then someone else has a site with 1000 backlinks most of which are PR 1 or below.. What are your thoughts? How many backlinks is too many to bother trying to compete with? What's the sweet spot?
