Question

One of my previous campaign (CBO+open Targeting) is kinda doing great, and when I increase the budget, the performance goes down(low sales on increasing budget). And when I again lowered it, the sales increases(high sales on lower budget).

I wanna double the sales with more ad spending but I don't understand this campaign algorithm or whatever.

Daily ad spending set by meta: Only $50

Answer 1

Your CBO + open targeting campaign performs better at lower budgets because:

Budget spikes reset the learning phase – Meta needs time to re-optimize, which can hurt short-term performance.

Higher budgets broaden reach too fast – Meta starts targeting less qualified users.

CBO gets less efficient – It struggles to allocate higher spend smartly without fresh signals or creative variety.

What to Do:

• Scale slowly – Increase budget by max 20% every 2–3 days.
• Duplicate campaigns – Let each run with its own $50–$75 budget.
• Switch to ABO – Gain tighter control at ad set level.
• Rotate creatives – Prevent fatigue as ad frequency increases.
