Hi Last week I put the Add This bookmark on my site, this is one of the best SEO things i have done. I have now got inbound links from Facebook, Digg, Stumble Upon etc. If you have a good site thats worth bookmarking I would put it on. Here's a link to my site, if you have 2 mins please bookmark it. http://www.heritage-supplies.com If anyone wants to exchange links, I have a link page please PM me (must be relevant) Cheers All
