If you've ever run ads, you've probably lived through this:
The first few days of a campaign. High cost per lead. Barely any results. The urge to pause everything.
That phase is called the learning period β and pausing your campaign during it is one of the most expensive mistakes you can make.
Here's what's happening: Meta's algorithm is testing different users within your targeting to figure out who's most likely to take action. It needs enough data to optimize properly.
How long it lasts: usually 7 to 14 days, or until you hit around 50 optimization events.
What to do during it: don't pause, don't make sudden budget changes, don't swap out creatives.
What to do after: look at the real data, then adjust based on actual results β not gut feeling.
Strategic patience in the beginning equals better results over time.
