Not all improvement types are appropriate for all Google Ads accounts.
You can disable any improvement type in the account's Settings – find this by navigating to the account in Opteo, and clicking the Settings icon in the top right corner.
Under Active Improvement Types, uncheck the boxes of any improvement types you don't want Opteo to look for.
Click Update Improvement Types when you're done. To re-activate an improvement type again, simply visit Settings and check its box.
Note, the changes you make here will not affect any of your teammates who manage the same client. Settings are personal to you.
