In the Reporting section, you will see a variety of prebuilt Google Data Studio templates, not only for Google Ads but also for Microsoft Advertising, Facebook, and Google Analytics. You can see the content of each report by clicking on the Preview link.

After you decide which of the reports will better suit your needs, click on the Use this template button.  Please note, that Free Trial users only have access to the first Google Ads report template. All other reports will be available after activating your subscription. 

In order to populate your template with your own data, you have to copy the template and add your data source (such as your Google Ads account). Please see the detailed instructions here.

Wondering why do we use Google Data Studio templates instead of creating our own solution? You'll find our thoughts on this here
