I was lucky enough to be able to test the service before being released here and I am absolutely amazed!
1. The web interface is kickass, plain, simple, but yet very advanced, giving you 100% control over your link building campaigns be they 1, 2 or 3 tiered. I really like the Drag & Drop interface for customizing the properties of each tier!
2. The links built are really done by hand as when I look at the Web 2.0s they all look professionally done, customized skins, text neatly arranged and formatted, images related to the topic are inserted and etc.. My campaigns were finished in start of July and when i now checked all Web 2.0s are still live and kicking. Awesome, isn't it?
3. Campaigns are with good turnaround time which varies depending on the size of the campaign
4. Communication with OP is great and i see some of the features and suggestions i gave as feedback were incorporated into the website.
5. I have seen tremendous SERP movement with lots of positions up for the keywords i targetted in the campaigns
I really like the service, the site is great, the links are great, the results are great! What more could one want?!
Best of luck with sales OP!
