Hey everyone, I'm new here. I'm building backlinks for my website, but still confused about this. When I post comments on a website post which has a page rank like 5 and the post on which I'm commenting on has a page rank of N/A is that useful? In my opinion the page on which i'm commenting on should have a high page rank so my link can be considered a quality backlink. Or it doesn't matter? Am I wrong? Just the domain with high rank matters in this? Please explain me this. Thanks everyone.
