When your search engine rankings fluctuate, or even if your site
drops from the rankings, what does it mean? Understand that these
things are going to appear to happen much more often and they WILL
happen to you.
What you DON’T want to do is make any changes to your Web pages
because of fluctuations in the rankings or because your site drops
out of the rankings.
Remember that this year, rankings in the “traditional sense” of
the top 10 will be far less important because of the effect of
“personalization of search” which is already happening.
Far too many people PANIC in the short term, when they would be
wiser to just take it easy and not start making changes so quickly.
