Robinize

We tested it and really easily decided to buy it.
Apart from some small bugs in recognizing long-tail keywords, which I am sure will be solved quickly, there is nothing else to point out as a downside to it.

Really easy to use and it really did help position our content better and gain more traffic over a short period of time.

Thumbs up guys for everything you have done so far and hope to see more in the future.
