Bluematter offered me a review copy on this around the 11th of September.
I got my hands on the 150 package and had them diversified with two main anchor texts for moderately competitive keywords on an existing site.
Three of the keywords were in the 50s, one wasn't even in the top 250, the important one.
Around the 17th ranks saw a massive increase, I got to the top 20 for most of the keywords within a few days and they're still steadily climbing, Yahoo #1 for most of them and it's popping up in Bing as well a lot. The best part is that the keyword that wasn't in the top 250 popped up too, at the moment it is #59 but it was in the top three for a while.
Here are the main kws I'm tracking
I know for a fact that I'm ranking for a lot more keywords due to the traffic I'm getting, here's a graph on how the site blew up on the 17th:
Today I'm getting loads of traffic as well, I cannot imagine what I will get when the ranks stabilize in the top for those four as well.
Because it was a review copy I also got a chance to look at the report (as far as I understand, regularly you will not get one) and the sight was good. I found practically all of the 150 links promised, a few sites were down at the time of checking.
The sites had a lot of variety, PR 1-5 and most if not all had less than 10 OBL. Not like your average network where you see viagra, weight loss and whatnot in a single footer. In fact not all of them were in the footer, some were in the sidebar, some in the header I believe, all in notable places though. Of course as promised, it was all in English as well, lots of unique content on each site and whatnot.
It's a tad early to say just how awesome this is as I can still see ranks increasing but I think going from 20 to 400 hits a day is well worth it for the little money you're going to be paying, I would've made it back already by now and will definitely continue using this.
Bluematter also had amazing communication, all of my emails were answered rather quickly, same thing with PMs.
Recommend!
Cheers Bluematter!
