I'm 90% sure at the moment that an algo update has in fact taken place and the QS bot is stable now. What I am seeing is that my QS scores are a lot more diverse now. For example I have 9s and 8s in my account that I never previously had. Hitherto my keywords went from 7 to 10 and vice versa with nothing in between.
Right now I'm sitting on a spread which is about 15-20% less than 7 with 8s, 9s and 10s. So it's still looking pretty healthy for me. Having said that I have purged quite a lot of 3s and 4s in the past few days.
For the life of me I can't understand why Google didn't just come and say "Hey guys we tweaked the algo. It was a bit buggy at first but what what you are seeing now is your new QS reality so get on with it."
In general I think the QS idea has merit but the road to hell is paved with good intentions. Altho QS has purged a lot of rubbish from the SERPS the "collateral damage" is breathtaking - if you read some of the Adwords forums. Based on the regular and quite arbitrary application of game-changing activity we have seen from the Adwords bosses I am definitely going to be Adwords-proofing my income next year. I don't want to build an empire and end up without an income overnight because the Adwords product manager had a bad day at the office.
