Facebook Ads and the Learning Phase

Loomer is one of the most cited independent Meta ads practitioners, and this piece turns the abstract 50 events rule into simple math you can run against your own product's cost per purchase before you set a daily number.

• Rule of thumb: multiply your expected cost per action by roughly 50 to 75 to estimate the minimum weekly budget needed to exit learning.
• Consolidating into one campaign, one ad set concentrates the signal Meta needs instead of diluting it across many small ones.
• Not exiting the learning phase isn't fatal if results are already acceptable, so don't chase the milestone for its own sake.
