What are the best settings for a Facebook ad?
Most settings in Ads Manager barely matter. The five that decide your result are the campaign objective, where the budget sits, how wide the audience is, the placements, and which conversion event you optimise for.

The five that matter
| Setting | What to do | Why |
|---|---|---|
| Objective | Pick the thing you actually want — sales, leads, messages | Meta optimises toward the objective, not toward your hopes |
| Budget level | Campaign budget for most accounts | Meta's help centre describes Advantage+ campaign budget as spreading one budget across ad sets in real time |
| Audience | Start broad, let Meta narrow it | Over-narrow audiences raise cost and burn out fast |
| Placements | Leave automatic at first | Delivery can chase the cheapest result across apps |
| Conversion event | The event closest to money | Optimise for purchases, not page views |
What about campaign budget versus ad set budget?
Meta's help pages describe Advantage+ campaign budget (what advertisers used to call CBO) as automatically managing one campaign budget across ad sets, continuously moving spend toward the best opportunities. For eligibility, Meta says the ad sets need the same budget type, the same bid strategy and standard delivery.
It's the sensible default for most small accounts because it stops you hand-feeding money to an ad set that isn't working. It is covered in full in campaign budget or ad set budget.
What should I leave alone?
Bid caps, manual placements, detailed interest stacking and day-parting. Each one narrows what the auction can do for you, and none of them fixes a weak offer or weak creative. If results are poor, the answer is almost always the creative, not the settings.
Also set the right objective before you worry about anything else — that choice is explained in which Meta campaign objective to choose.
