Fixing Capitalization Errors in Your Ads

One of the issues that marketers face when they have systems for automatically building creatives from feeds is quality control. I recently ran into an issue where I created around 1,000 new ads where the city name was IN ALL CAPS. Google of course doesn't like that much and I didn't like the idea of having to manually update 1,000 ads, so I put together the following script.

The script runs through your account for all of the disapproved ads and tries to find ones with words in ALL CAPS. I'm not sure what Google's limit on caps is, but in the script below, it looks for anything with 3 or more capital letters in a row. Then it replaces them, creates a new ad, and if it was successful, deletes the old ad.

I ran into some trouble trying to identify the reasons the ads were disapproved. It is not yet available in the API, but it has been requested. The other issue was that sometimes, the new ad you create will fail, which will cause you to delete the old one and not create a new one. I solved that one by counting the ads in the adgroup before and after I created the new ad in order to make sure my ad had been created. Again, I posted the feature request in the adwords scripting forums.
