I have been using William for months now and given him a range of link building jobs. Each time he has completed them quickly and effectively. From my experience he has provided the BEST link building from anyone in the DP forums or elsewhere for that matter. I have tried 5 different organisations this year and William is the only one that I go back to. Check online review here

Just received 60 links. There were some issues with the links, but they were resolved within the hour. Overall good, related links. All pages were cached in Google, almost all in MSN and about 60% in Yahoo. Good work + good customer service = happy customer! Check online review here

Made my first order had a few issues with some of the links and they immediately replaced the links. It was just a slight issue, but they were right on it. To those that mentioned any ranking from the links, I had them build internal links on small keywords, Im talking overture showed .9 -3.4 searches per day. Moved up to top ten on Yahoo for those keywords, top 5 on msn and one of my sites moved to top ten on Google. Again for smaller keywords, but for me the traffic to cost conversion is definitely there and putting in another order right now. Check online review here
