So basically i've been building backlinks from High PR sites. maybe not high pr webpages but high pr domains. lately i've seen some people sayin links from only high pr sites might be considered unnatural. so would it be wise to build backlinks from low pr sites too or should i just focus on higr pr sites. and by saying low pr i mean PR 0 and PR 1. although people might say i should not focus on pr but still i'd like to see some answers related to the question.
Thanx in advance!!
