One thing I've learned about SEO since getting into online marketing is to never buy any blackhat service. If it is too good to be true, it probably is. The way I see it, Google is already conscious of itself, and it "knows" a website based on its quality. Yes, these Penguin, Panda, and EMD updates are a pain in the rear, but we needed them. It's about time Google weeded out unfair players. Those who don't play the game right don't deserve to be a part of it. Learn from me, I used to rank #4 for a very popular keyword post updates and all was well. I got there with natural link building. However, due to my desire to rank higher, I bought a couple of those mass link building schemes (Xrumer, etc). Little did I know I was falling into a trap! Now, I am NO WHERE to be found for my keyword. The Big G slapped me and now I have to suffer the consequences. The moral of the story is to be careful with any blackhat service out there. You might just get the exact opposite of what you were looking for. Cheers.
