Even though it may sound like a dream, there’s a catch (isn’t there always?).
Here are some of the potential cons of this campaign strategy to consider:
Limited Flexibility: When you set a specific cost per result goal, you’re asking Meta to spend an exact budget for each conversion. It can restrict the campaign’s ability and potential to find new relevant audiences because it focuses only on audiences that have been converting so far in your campaign.
You Must Be Accurate: If you set a too strict cost per result goal then you may miss out on valuable conversions, and if you overestimate it then you could be spending more than necessary.
Performance Fluctuations: Meta’s algorithm is powerful, but it’s not magic. Factors like competition and changing audiences can make it challenging to consistently achieve your desired Cost Per Result Goal.
