Google works in mysterious ways, man!
A site of mine that's 9 months old was ranking 6 and 11 for the top keywords, getting me 25-30 (new) visitors a month. I'd watched it rank 78 and 92, then 64 and 80, then stall at 21 and 29, then go again (11 and 17), then 6 and 11.
Then, 2 weeks ago, I'm 176 and 195. Stayed like that till yesterday. Yesterday, I was ranking 7 and 13. Except that keyword 1 is now ranking lower (13) and keyword 2 is ranking higher (7). Yesterday, I got 10 new visits.
I'm thinking maybe Google isn't done yet, and I should wait a couple of days before I draw any conclusions.
But, even though I knew it does things like this, it's still annoying to go from a rate of 700 visitors a month to a rate of 0. Yes, even though I'm going back up and, by the time I'm done, I'll have a couple of thousand visitors a month, I am annoyed.
Just wanted to let y'all know that. That's all.
