Adwords Quality Score Update

I just made some changes to my ad text and landing pages....how long is it usually before the quaity score is updated?

 

I can't say that the quality score changed, since my particular campaign always said "good". But when I changed the ad text, my impressions went down dramatically in 24 hours. I let it run a few days, but it consistently stayed much lower than normal. I changed the ad text back, and my imrpessions went back up in 24 hours and have stayed relatively level ever since.

 

Hi,
I have an adword account which i setup campaigns previously but it failed miserably...i understand that there is a quality score system in place in google...does it mean that i either have to use back this account to improve my quality score or should i setup another adword account to start fresh ?

 

you can use this account! Delete the old adgroups and create new ones. I dont suggest to use multiple accounts.

 

LP QS's are updated monthly, although sometimes miore frequently.

 

Are you sure.
I have done few changes in my ad and I don't see much changes in it.

 

yes, and I was talking about the LP (landing page) quality score.

 

Has your advert text changed to include the keyword (when it didn't previously)?

If not, then the change may well be quite small, and not enough to move you to another level.

What I'd like to know is whether Google has only the displayed level of accuracy for QS's (£0.01,£0.02,£0.03,£0.05,£0.08,£0.10,...) or is it more complex (£0.01,£0.011,£0.012,£0.013,...) and just grouped together when displayed in the reports.
