Adalysis supports labels at the account, campaign, ad group, and ad level. You can apply them manually or automatically, based on your alert settings. Labels also play a key role in multi-ad group testing.
Adalysis doesn't support MCC labels, but you can use account tags instead.
Adding, refreshing, and deleting labels
You can update all of your labels under Manage > Labels within an individual account. You'll also see options for adding labels across the platform, including:
Alert settings
Labels menu (available on several screens under Manage)
Filtering by label
Look out for the Filters menu across the platform. Click Create filter and search for 'labels'.
