As everybody is no doubt aware, Google updated their Adwords system. The once transparent-ish scoring criteria for determining ad ranking placement has gone a distinct shade of grey. Google, in an on-going bid to be less secretive and more transparent, haven’t told advertisers exactly what criteria they should meet.

So, people have been speculating.

Aaron has a few thoughts, as does Andrew. I lean towards the view that account history has a lot to do with placement, and now there’s some landing page criteria in the mix. I’ve heard as many people complaining about the changes as I have heard people say they haven’t noticed much difference.

Who said PPC is just about getting your credit card out?
