I noticed something today that I haven't noticed in the past (likely my fault). When I create a new ad group in google, write an ad, and populate keywords, Google immediately serves up a quality score.
So I went along and put in my keywords and got scores like
3/10
4/10
3/10
So I check the landing page and start thinking about what I might need to change to rank better... and how much time it will cost in programing hours.

Then I check Adwords again. Suddenly 20 min later:
10/10
10/10
10/10

Zero clicks, low volume terms, and I wasn't paying enough to be on the first page.

Has anyone else noticed similar behavior? How long are the Quality Scores volatile for?

Also: What is the seeo and how kan i mak money it?
