This script is really useful for long term ad A/B testing for bigger accounts.
- Track changes or additions to the Ad Group and calculate statistical significance for A/B testing from a specific date. You can see the date range for each test in the Dates list.
- Once the test has reached at least 95% significance, and the Ad Group has 2 or more ads, more than 50 clicks, and 500 impressions for the test period, you will find a list of the Ad Groups which are finished testing in the Results sheet.
- If/when you make any changes to the ads in the Ad Group (pausing an ad or creating a new one), the script will automatically detect the change and start gathering new data on the day the change is made.
- If the Results sheet is empty, then the A/B tests are still running and there are no results currently available.
