Recently, I started posting blog comments to give my site some better quality back links. I noticed that when checking back links with Yahoo Site explorer it is showing not only links for the pages I have posted on, but most all pages of the blog. Why would this be, is Yahoo site explorer screwed up? Will Google treat these as actual back links.
No, there will be a plugin on the blog that posts the most recent comments, hence your post and link appearing on many pages from that site, over time the links will be replaced with others.
That was my thought but I am not seeing it on any of these pages, and it is not limited to just one blog either. Not complaining of Google counts all of those as backlinks.
