I call this the Google index Spasm (other’s call it the Google Dance):
After a couple weeks in existence, my new blog found itself on the second page for it’s main keyword. After fluctuating between rank 12 and 18 for another two weeks, it fell to rank 80+… If I didn’t know better, this would have caused me to be very disgruntled.
I don’t know the purpose is of the Google Spasm, but it’s kind of funny and annoying at the same time.
Today my blog is back up to rank 19 for its keyword. I think some call this the “sandbox” but my site wasn’t in it for very long. Although that could be because it is a blog.
