Definitely works. The reason people don't see the same results as before is not the software but the content. As we all know Google released several algo changes and made ranking a website with crappy content impossible.
I have personally used Senuke X (Lite) to move two websites from nowhere to second page during the last two weeks. I'll wait a little bit more and push them further. No fancy pyramids or link wheels.
The question is whether it is worth $150 per month. Definitely - NO. There are other tools that can do the same job for much less.
Do you own Senuke or pay $150 per month? insuranceman
