In brief
Three decisions control how much you spend and how: the budget, the bid and the schedule. They are set at the ad set level (or at the campaign level, depending on the option you choose).
The budget
- Daily budget: an average spend per day. Simple and flexible.
- Lifetime budget: a total amount spread between the start date and the end date. Useful for an event.
- Meta may spend a little more one day and less another, but it respects the average or the total.
The bid
The bid strategy tells Meta how to spend:
- Highest volume: get the most results for the budget, with no cost cap. A good starting point.
- Cost per result goal: aim for an average cost. It requires a sufficient budget.
- Bid cap: never exceed a set amount per bid. Reserved for advanced users.
The schedule
Choose a start date, an end date (or none), and optionally delivery hours if you use a lifetime budget.
The learning phase
After a launch or a significant edit, Meta learns how to deliver well. To exit it, each ad set needs about 50 results (the optimized event) within 7 days. Otherwise the status becomes “Learning limited”.
Calculate a rrealiztic budget
Minimum daily budget ≈ (target cost per result × 50) ÷ 7
Example: €10 per result → 10 × 50 ÷ 7 ≈ €72 per day to exit learning in one week.
Pitfalls to avoid
- A budget that is too low for the objective: never enough results to learn.
- An unrealistic cost goal: delivery stops because no auctions are won.
- Changing the budget by more than 20% at once: learning restarts.
- A campaign that is too short to learn.
Key takeaways
- Daily = flexibility; duration = precise period.
- Start with highest volume.
- 50 results within 7 days to stabilize.
Practice in TRIALO
Create two campaigns with a daily budget of €5, then €50: compare the amount spent and the number of simulated results.
