I just read this very informative article by Brian Rogel about how Feedburner steals the unique backlinks you are figuring to get using the CommentLuv plugin on your WordPress blog. Your link juice is outright stolen by Google! In short, Feedburner usually changes the backlinks to one that points to Google that looks like this – “http://feedproxy.google.com/……”
Turns out this backlinks stealing has to do with tracking in Feedburner, which is managed through a little setting which would seem innocent if you even understood what was going on. Brian Rogel did such a great job in his article describing this I’ve just included it here so you get all the details about what Feedburner does automatically, and what you can do about making sure you get the backlinks value you intended when using the CommentLuv plugin. . .
CommentLuv is one of the best plugins available for WordPress. It allows any blog owner to reward the people who comment with backlinks directly back to one of their own blog articles.
CommentLuv is growing in popularity and many large well known blogs are starting to jump on, but there is one major hiccup that is still not very well known, Feedburner backlinks stealing:
