Sorry for all of those who think about this is totally noob question. but I'm so curious about this. I've searched my backlinks through yahoo by input "link:mysite" I founded that I 've got many backlinks from one domain (almost on every pages) but I don't know the authors of that page. The problems is the script they used to refer my sites. I've never seen it before and It's seem to be no answered when I googled it. For example Any commnents is so appreciate. PS: What is urchinTracker? I'm really scared of it.
