In Targets, every campaign sits in a campaign group, and every campaign group has one CPA or ROAS target. Opteo judges each campaign against its group's target, and that decides which Improvements you see. How you group campaigns has a big effect on how good those Improvements are.
Campaign groups and their targets only apply inside Opteo. They don't change anything in the ad platform.
Group by performance, not by theme
Put campaigns with a similar CPA or ROAS in the same group, even if they're about different things.
If a group mixes campaigns with very different results, Opteo treats the weaker ones as underperforming and suggests aggressive changes to pull them towards the group's average. That often cuts conversion volume, which is rarely what you want.
For example, competitor campaigns usually have a higher CPA (or lower ROAS) than brand or generic campaigns. Give them their own campaign group so they're judged against a fair target.
Opteo starts you off by putting brand campaigns in a group called Brand Campaigns and grouping the rest by campaign type. Check these groups and move campaigns where the CPA or ROAS doesn't fit.
Automatic vs Manual targeting
Each campaign group has its own target:
Automatic Targeting uses the group's 90-day average CPA or ROAS as the target, and updates as performance changes.
Manual Targeting lets you enter the target yourself, for example a client's agreed CPA.
Choose conversion actions first
Pick the right conversion actions before you group campaigns. The CPA or ROAS you see for each campaign depends on which conversions count, so grouping only makes sense once those are right. See Choose your Conversion Actions.
Most Improvements look at one campaign at a time. A few, like Add N-Gram Negatives, combine data from all the campaigns in a group, which is another reason to keep groups tidy.
