I had high hopes for this package because of the other great reviews but my results have been bad.
I bought 3 linkpwns. They started work 29 Sep and completed it on 11 Oct. These are my results as of 25 Oct.
Linkpwn #1
The 2 kws were historically at #2/#3 but had slipped down to #8 so I ordered the pkg. Then I discovered I'd made a coding error on the page. As soon as I fixed it the page went right back to #2/#3. This was before the linkpwn had been done. I should not have ordered a linkpwn on this URL. I'm not counting this one against them because I'm still just below the corporate site and there's probably no way to beat it, but the rank now is exactly how it was before the linkpwn.
Linkpwn #2
kw1 currently 68 (was 55 before the linkpwn)
kw2 currently 114 (was 65 before the link pwn)
Linkpwn #3
kw1 currently is not in top 200 (was 42 before the linkpwn)
kw2 currently 90 (was 16 before the linkpwn)
I went back and forth with George on their ticket system. It seems that they made the links but they just didn't help my rankings, and in fact hurt 4 out of 6 kws.
George swore that for linkpwn #2 that I was wrong and that I was ranking on page 1. I explained to him that for whatever reason SEO tools, scroogle, etc. have shown those two kws on the first page for the last several months, but in reality they are not. (As confirmed by a manual google.com search in the US and by my server logs that I am not getting traffic from those kws.) I sent him screenshots of my kws in positions 68/114 but I still don't think he believes me.
For linkpwn #3 George blamed it on a panda update since the site is pretty thin. I guess there's no way to confirm or deny that but all I can say is that the kws had been steadily moving up the serps until the linkpwn was done and then they tanked, just like they did on linkpwn #2.
So I could isolate the results of the packages, I hadn't done any link building for a month before ordering and didn't do any while they were working on it and for 17 days after they finished. (I started doing linking again by myself on the linkpwn #2 kws on 28 Oct and by the 31st my serps started improving again.)
I guess they did their work and made the links, but it does leave a bad taste in your mouth not just to have spent $300 and have it not work, but to have spent $300 and have it actually hurt your rankings. That hurts much worse.
