I have a competitor running a cookie cutter ecommerce website in the same niche as me. In fact, he uses the exact same system, and has the exact same 50,000 products on his site with the same URL's and everything. BUT... he shows 30,000 inbound links in yahoo site explorer and I only have 8000. Upon further research, all of his inbound links are his OWN PAGES on that site! They aren't even from other domains. What am I missing? I do internal linking as well, but I just can't figure out what he did to get all those showing as inbound links??
