|So near as I can tell if you change the text of your ads the average CPC will go immediately up until the new ad's CTR history "overcomes" the old ad. |
Which may take some time on an ad 6 months running that had built up the credibility to broad match more liberally.
Appears to be a disincentive to improve one's ad copy. So coming up with an improved, more relevant ad idea in the shower will cost you?
Too easy to be cynical about algo changes like this.....
