Auto ads experiments let you compare different Auto ads settings on your site to determine which performs the best. For example, you can test different ad formats and ad loads, or compare having Auto ads on versus Auto ads off. You don't need to edit the AdSense code on your site to run Auto ads experiments.
Create an auto ads experiment
- Sign in to your AdSense account.
- Click Optimization, then Experiments.
- If you have other experiments running, click Creat new experiment.
- In the "Auto ads" card, click Create new experiment.
- Select the site on which you want to set up the experiment.
Tip: You can search or filter to find a specific site.
- In the ad settings preview, select which Auto ads settings you'd like to change for the variation. You can use the Show original switch to move between your original settings and the variation.
Note: You can't run experiments on the following Auto ad settings:
- Click Start experiment.
- Give your experiment a name.
- Turn on Automatically choose winner, if you want Google to automatically apply the winning setting after the experiment has finished.
- Click Run experiment. Your experiment now moves into the "running" state, and we start collecting data.
Evaluate your Auto ads experiment
Visit the "Experiments" page to monitor your experiment. You can click Compare settings on the experiment's page to review the original settings and the variation.
When your experiment has collected enough data, you can evaluate whether the original setting or the variation is performing better.
Note that the metrics in Auto ads experiments show you the impact across your entire site (including any ad units you're using), rather than just Auto ads. This helps you better understand the effect Auto ads has on your site, particularly if you have existing ad units.
