I have a 1 week old site that has unique quality content on it. I only wrote 3 articles for article directories, and that was my only backlink work done so far. TO my surprise, my site had over 100 backlinks when I checked today. The majority of backlinks were blog comments. The anchor text used was "**my keyword** online shop". I don't know whether to be concerned or a little satisfied for the free backlinks? At first I thought it could be a competitor blasting my site with crap backlinks, but the more I thought of it, why would a competitor waste their time with a site thats 1 week old and not even ranking? My second guess, is that it is someone who owns a site with a similar domain name, and in their attempt to backlink, they used my domain instead of theirs. I really don't know. Should I be concerned?
