I'm testing a large CBO campaign ($2000/day) with multiple ad sets, each containing a single ad. The product price is $28, the cost is $8, and the profit margin is $20. I wanted to ask if the following approach makes sense: If my ad sets don't start delivering, should I increase the bid cap by $1 every few hours until some ad sets start getting impressions? Once impressions begin, I stop increasing the bid cap and monitor performance. Example: 50 ad sets launched at $24 bid cap โ No impressions After 2 hours โ Increase to $26 bid cap After another 2 hours โ Increase to $28 bid cap After another 2 hours โ Increase to $30 bid cap โ 5 ad sets start delivering At this point, I stop increasing the bid cap and analyze these 5 ad sets. Then, I decide whether to keep, increase, or turn them off. Once these 5 ad sets are optimized, I continue increasing the bid cap for the remaining ad sets until they start delivering. My question is: How long should I keep increasing the bid cap? Should I continue raising it indefinitely until all ad sets start getting impressions, or is there a logical limit considering my $20 margin? Would this method be considered a valid and effective approach?
