From around December 13th/14th I noticed many of our clients expereinced some dramatic change in rankings, some which levelled out and some which didn't.

Did anyone else notice this? I know that the algo is constantly updating now but I've yet to figure out what this change pertains to.

In a couple of days I will have finished analysing all the clients so will be able to better see (hopefully) any patterns emerging, but just wondered if anyone had already beaten me to it? Thanks.
