I've had 8 campaigns executed for my sites and so far, I've seen a boost in rankings for every domain. My sites never had very many social signals to start with so to keep things natural I've done the home page and then two internal pages done for each campaign. One of my domains was aged, but it had been sandboxed and not ranking well and then during the campaign I saw it start ranking again at the top of the 2nd page. Overall, I've seen great results from this and Raj the provider has been great to work with and answer all of my questions on Skype. Just wanted to share the results I'm seeing.
