Do You Lose Adwords Quality Score History If You Change An Ad?
Someone searched for the following and got to my blog:
change price in google adword text without reducing “”quality score”"
They probably didn’t find a good answer at the time so I’ll have a go now.
A common concern is that if you change anything at all in the ad copy you start afresh with a new ad and lose all benefits of a good quality score.
Quality score is tied to keywords not ads so in fact you don’t lose the quality score history by changing the ad copy. It’s a bit counter-intuitive. People click on ads. Click through rate is one of the biggest factors in determining quality score. However, it’s the click through rate associated with the keyword that counts. The quality score isn’t reset if you change an ad.

This is a tricky one…
Quality score is a keyword issue - but the relevance between a keyword and an ad does affect quality score.
“Quality Score is a dynamic variable assigned to each of your keywords. It’s calculated using a variety of factors and measures how relevant your keyword is to your ad text and to a user’s search query.”
(from: http://adwords.google.com/support/bin/answer.py?hl=en&answer=10215 )
If you change your ad text, you generally lose the history of that ad.
But I’ve noticed I’m able to constantly split test ad variations without any significant impact on quality scores.
