We’ve just added another ETA mass upgrade tool on the ad group screen.
The way the ad level or ad group level tools work are very similar; the main difference is the selection.
If you want to upgrade very specific ads to ETAs; then use the ad ETA upgrade tool.
If you want to find ads within ad groups to upgrade (such as only upgrade my highest conversion rates ads among these selected ad groups); then use the ad group ETA tool.
This short video will explain how to use the upgrade tool and the differences between upgrading your ads from the ad screen or the ad group screen.
Here’s a quick slideshow that will walk you through the new features.
