Google Adwords Optimization Strategies 1. - Ad text Variations

A very basic optimization strategy is adding more Ads to an Ad Group.

Sooner or later one of the ads will perform better than the other(s) so that if you run only the better performing ad you get more visitors/conversions. Also after maybe you can create an even better performing ad... and so on.

My first (basic & slow) script is checking your whole account for Ad Groups without more Text Ads (Adwords usually highlight the Ad Group without an Ad Text, and also this script will list those Ad Groups too).

The problematic Ad Groups will be listed on the Logger Output and you'll get an email about the number of problematic Ad Groups... and you can start adding shinny new text ads to make a very basic A/B testing.

Yeah, I know the script is slow and not optimized (if I not group the output by Campaigns it could run faster), however it could help you a lot especially if you have at least 100 Ad Groups or even more...

Please don't hesitate to share at the comment section how many Ad groups you have found without two or more Ad texts :)
