A month ago, my domain was on page 4 of google. Over the month, my domain went up the ranks and was number 3 on the first page of google for a keyword. It stayed there for about a day or two and then dropped back to page 4 and today I'm on page 2. The domain is old and I've done nothing different in promotion. What would cause it to jump around so much?
The Google dance It "may" be Google's way of testing how your site performs when given a higher ranking. Or it "may" be that you have gained a few relevant back links that Google is starting to take into account and adjusting the SERPs accordingly, but has not reached all data centers yet.. There are several reasons why this "may" happen.. unfortunately know one but Google really knows for sure and anything else is only a guess on our part.. That's why I keep saying "may" Cheers James
