What is one way to upgrade all Smart Shopping campaigns to Performance Max at once?

The method of upgrading all Smart Shopping campaigns to Performance Max at once involves utilizing a specific feature in Google Ads that allows users to efficiently manage multiple campaigns. Selecting the Performance Max upgrade notification within Google Ads simplifies the process, as it provides a centralized method to apply the upgrade action to all eligible Smart Shopping campaigns in one step.

This approach takes advantage of the integrated functionality within Google Ads, designed to streamline campaign management. By choosing to apply the upgrade through the notification, advertisers save time and avoid the potential complexity of upgrading each campaign individually.

The other available choices focus on either actions within the Merchant Center, the Campaigns page, or the Recommendations page, none of which provide the same level of efficiency for bulk upgrading that is found directly in Google Ads. The notification in Google Ads leads directly to the capability to apply the upgrade to all relevant campaigns simultaneously, making it the most effective option.
