Do not make any significant edits while the algorithm is in the learning phase.
Significant edits include:
- any change to targeting, ad creative, or optimization event;
- adding a new ad to your ad set;
- pausing your ad set for seven days or longer;
- changing the bid strategy.
- don’t create too many ad sets and ads at once. If you do, the algorithm will learn less about each ad.
- don’t put too little budget into your ads, and don’t put too much. Aim for the budget that will get you 50 optimization events. Also, keep in mind that frequent budget changes can result in your ad set re-entering the learning phase.
