If a type of Improvement doesn't suit an ad account, switch it off so it stops appearing.
Switch Improvement types on or off
Open the ad account's Improvements and stay on the Active tab.
Click the lightning icon at the top right. It shows how many types are switched on, for example 37 Types.
Untick the types you don't want. Types are grouped by Exclusions, Adjustments, Keywords and Negatives, so you can switch off a whole group at once.
This applies to everyone on your team, for this ad account only. Other ad accounts keep their own choices.
To change how Opteo judges an Improvement type instead of hiding it, use Algorithm Settings.
Sort Improvements
Use the sort menu at the top of the Active tab to order Improvements by Priority, Type or Date, and switch between ascending and descending. Improvements stay in their groups; the sort applies within each group.
