Welcome to WebmasterWorld Guest from 18.104.22.168
The diagnostics say that the ads and ad text are fine but landing page needs improving. Google have told me lots of times before that the site is great so a bit confused.
I've made a lot of changes in the account the last couple of days and use conversion optimizer for most campaigns so I wonder if it's just all the changes have made the QS scores drop temporarily?
I sure hope so...
I am completely at a loss, nothing like this has ever happened before. So, because everything has gone from 8 to 1 it would appear it's a blanket issue with all my landing pages (and nothing has changed in the last week or so that I can think of, certainly not of any significance) or it's just an effect of adding lots of new keywords, deleting non-converters etc and everything has gone bad QS wise temporarily and will come right soon.
I'm really stuck what to do and would appreciate any expert advice.
