you might be interested in bidding on german philately.
you might not be so interested in getting clicks for german rubber stamps.
Thus in order to effectively test ad text, etc., I have to pay an average of three times what I used to pay to get onto the first page. Once on the first page where people can see the ad text tests, the testing will be more relevant.
think of this as a cost of doing testing and research.
then improve your campaigns, ad copy and landing pages based on what you learn to get your quality scores up and your bid prices and CPC down.
