After the google penguine updates, is it safe to get backlinks from comment posting? Is there any problem If I get backlinks from blogspot comments?
Try to mix it with another backlinking method, I have experienced great results from buying links/posts from a relevant high pr sites rather than blogspot comment.
You shouldnt worry about the # of links, just as long its a quality site and your rewards was due to a being helpful.
if the comments are on topic then they will be fine. Only if you post onto unrelated stuff will it do nothing/maybe hurt you. but as said above, try to mix up the links as much as you can.
