I had a few basic questions I wanted to ask.
If you are building backlinks by commenting on niche related blogs can you build links multiple times on the same blog? If the blog has dozens of post and you honestly read and comment on several post does each comment build a backlink?
I have come to understand that blog pages and not necessarily your sites URL are indexed in Google. If this is true when commenting should you post not just your URL but also your page extension that you are trying to help rank on the blog your commenting on?
