Changed my ad copy...lost quality score

So i'm an idiot, I decided to include a coupon code in my existing PPC ads. By modifying old ads instead of creating new ones, I have lower all my quality scores and thus reduced my traffic.

My question is, can I undo my changes? Another bone headed move, my coupon code expires Monday, so i'm going to have to modify them again to delete the coupon code.

 

Nope. Never change/edit ads. Always create new ones.

 

Try putting them back, you used to be able to get that QS back. I haven't editted an ad in ages though, only done new ones.

 

Why change ad copy? Just create a new one to test. That way you have nothing to lose...

 

Changing Ad copies with impressions and clicks can definitely lose their CTR.
