Firstly, Review Your Schedule and Budget
If your budget is set too low or the ad is scheduled for just one day, the system may initially prioritize strong distribution but then increase costs as competition rises. Try running your ad for at least 3-5 days to give the algorithm time to learn and optimize effectively.
Secondly, Avoid Constantly Turning Your Ad On/Off
Turning your ad off after the first day and then turning it back on can make the system treat it as a new campaign, forcing it to start learning from scratch, which may result in higher costs. Instead of toggling it on/off, consider gradually reducing your budget if you notice high costs to keep performance stable.
