Campaign, ad set, ad: what each one controls
Three levels, three jobs. Know which one holds the budget and you’ll skip half the beginner mistakes.
Three levels
A Meta campaign reads top to bottom. The campaign holds the objective, and sometimes the budget. The ad set holds the audience, budget, placements and bid strategy. The ad holds the creative: image or video, hook, copy and call to action.
Each setting lives on one level only. Looking for the audience at the ad level, or the creative at the campaign level, means looking in the wrong place. That’s the first habit to unlearn.
Where to put the budget
You have two options. Set the budget at the campaign level, and Meta splits it across ad sets based on what works. Or set it on each ad set, and you decide the split yourself.
Campaign-level budget is the simplest and most common: it lets the algorithm do its job. Ad set budgets are useful when an audience must get a set share of spend, like a test you don’t want the easiest audience to crush.
How many ad sets, how many ads
Few, to start. One campaign, one or two ad sets, three ads per ad set. More ad sets split your budget, and a split budget stops learning: each ad set ends up with too little data.
Add complexity later, once an audience has proven itself and you can fund a second ad set without starving the first.
The habit that helps
Before every change, ask which level it touches. Changing a hook affects the ad and doesn’t always reset anything. Changing the audience or budget affects the ad set and can restart the learning phase.
Adwize walks you through the same logic when it suggests a change: what moves, on which level, and what it means for delivery.
