I checked the ranking (using cuterank) for some of my sites today and one of my main money sites showed that it was ranking on the first page for nearly all of the keyword phrases I was targeting. These phrases are high competition phrases that I've been working towards for the better part of a year. The average placement increase was about +35 or so. I figured that this must have been a dance, and sure enough, I checked my rankings again 3 hours later and I had been dropped back to an average of +4 higher than my previous rankings. I'm no stranger to the dance, but I was wondering if anyone here has any retrospective thoughts on what this could mean for a site; for example: is this an indication that I'm doing something right, and that my site has potential to hold those rankings if I continue my efforts, or is it perhaps just that I checked the rankings when google was (hypothetically) part-way through an update?
