I have this keyword that was in >500 in SERP. For 3 weeks I was able to bring it on the top#25. On the 25th of December 2009 there was a bought traffic because they are trying to boost the Alexa and I know it's not good but well, there's no wrong in trying. Yesterday, when I checked the SERP again, the keyword is no where to be seen, it went back to >500. I wonder what happened because it only stayed for a week on top #25 then gone. I cannot say that I overdone targeting the keywords because I just did the normal thing. I know google rankings are like investments in a bloody bank but I'm angry that it seem my effort was gone in the wind. So, my question now, what do you think guys happened. Does the bought traffic has something to do with this SERP fluctuation? I'm really confused now because i am doing the normal thing and all the keywords fluctuates. or I'm thinking the site is maybe is on penalty? This fluctuations in SERP ranking was so big and impossible. This is the first time it happened to me. Your advise guys on how to get it back will be highly appreciated.
