Google AdWords Creative Tip

Submitted by Jeremy Palmer on Thu, 03/06/2008 - 00:01.
Never delete or edit an ad. It's always best to pause your ad and create a new one. Whenever you edit an existing ad you lose the CTR data for all practical purposes. I just did this 5 minutes ago... Oops.
It's always nice to be able to go back into your account history and see how each change effects your campaign performance.

Yes, this is great advice! Who wants to lose all those ad copy stats?! You also lose the ad copy itself, which makes it harder to create and test new ad copy without repeating yourself (unless you're storing the ad copy in Word .doc's--who does that?!) I'm not sure why Google doesn't provide this advice somewhere on the ad copy pages.
Good point but lost on someone like me who wrote Packrat 101.
I seem to never delete anything, anywhere. People looking over my shoulder are constantly amazed at the sheer number of bookmarks in my browsers and nested folders on my drives.
I am glad to now have a good reason to keep something else. 8-)
Oh, and you should see my sock drawer.

Great Blog.
An update explaining why your history is wiped out:

I know this is an old post, but I just came across it. When the Google developer said
"That is why when edited an ad, it may not impact the quality score as much as starting a new ad from scratch."
Does he mean impact in a GOOD way? It sounds like he is saying, editing an existing ad, allows your new ad to start with some quality score information, instead of creating a new ad that has no quality score data.
When you edit an existing ad, it keeps a link to the original ad, so wouldn't it keep a link to the quality score of the original ad?
I really don't understand why Google would spend the extra time to add into the system that creating a new ad would be different that editing a new ad. Why should they care? I would think they would want you to delete old ads, so they don't clutter the system. I know it's normal for software developers to be anal, but damn. LOL
Thanks.
