Has anybody else noticed that Google has gone berzerk in the last couple of days? I have a blog that ranks #3 for a very popular keyword. When I accessed Analytics yesterday, I noticed that my visits dropped dramatically. I did a search and couldn't find my blog anywhere! Naturally, I panicked, but decided to wait a while. This morning, I did a search again and found out that my blog SERPs were back to normal. So I was happy... for a few hours. Amazingly, a couple of hours ago my blog disappeared again!!!
SERP's keeps on changing all the time, maybe it Google was fetching index data from an out-dated data center
