Impressions suddenly dropped
A few days ago I’d increased budget for a pMax campaign by less than 20%. But impressions have been low ever since. As far as I understood from my years of experience the learning phase was only triggered with budget changes of over 20%. But maybe pMax is more sensitive. The budget was the only change made. Prior to the increase performance and ROAS was very good.
Can anyone shed light on this? Or have you had a similar experience.
