I have a +500 page website with A+ content, it took my 2 years to get there and we are still expanding the website. I had pretty good rankings (mostly nr 2 or 3) for many many keywords, right behind the big brands in my niche. My businessmodel is affiliate. On februari 9 th my rankings dropped on some very important keywords from nr 2-3 to nr 9 to 15. Whas there a particular Google update around that time? Is there a way to find out what is hurting my website? Is there a blackhat way to fix it?
