I maybe slow here but has the Google algorithm changed since the beginning of the month?

Hi there, there was a pagerank update. Many sites lost pagerank, which can be affecting your ranking

FWIW, i think so. I can't put my fingers on what it is that they've changed but something definitely isn't like it was in December. Ie. this was not just a PR update.

seems like there's a regular algo rotation in effect. in my area, i have a page on page 1 of the serps and a page on page 2 of the serps. depending on the algo in use, the page on page 2 of the serps is either widget.html or gidget.html
