No, the optimization doesn’t stop. Adspert is still optimizing the Performance Group and connected advertising campaigns to the nearest reachable goal.

For example, if the non-reachable goal is 10% ACoS and the nearest reachable goal is 20% ACoS, Adspert optimizes the Performance Group towards 20% ACoS.

When setting the Performance Groups goal, check the Scenario view. The curve on the chart forecasts goal values. There is a shadow behind the Scenario curve. The point where the shadow is the most narrow reflects the goal value that is the most within reach. The wider the shadow gets, the more the goal is out of reach.

Even though the optimization runs regardless if the Performance Group goal is reachable or not, we strongly advise you to set a reachable goal to get the best possible results.
