Google announced a new feature within Google AdSense that helps streamline the practice of testing various ad units through A/B experimenting.
Google said "we’re releasing a new AdSense experiments feature for your ad unit settings."
What does it do? It let's you use one piece of code and then define on the AdSense console end, which ad units you want to test within that ad code.
Google said you can test examples such as:
- Compare the performance of text-only ads to ads that have both text and display enabled
- Determine how ads with a visible border perform compared to those that are ‘borderless’ (where the color of the border matches the background of the page)
- Analyze the effect of changing the color of ad text on ad performance
Around 24 hours after you set up an experiment in your account, you’ll see a confidence score for the two ad units settings. This report will be found in the experiments report.
Here is the screen to set up these experiments:
