Upload ten creatives, check the account two days later, and the spend looks broken: one ad has most of it and the other nine have almost nothing. Brokers react by pausing the nine, or by switching the one off to force the budget elsewhere. Both undo the thing Meta is doing on purpose.

| What you see | What it means | What to do |
|---|---|---|
| One or two ads take about 90% of the spend within a day or two | Meta has found the creative that converts on your event | Nothing. Leave it running |
| The other ads get almost no spend | They are what Meta can shift budget to later | Leave them on as well |
| The winner’s leads fund deals | A true winner | Squeeze it, and start on its variants |
| The winner’s leads are cheap and fund nothing | Meta is finding the wrong merchant efficiently | Turn that ad off, and check the pixel |
Why you leave it
Meta is not failing to spread the budget. It is concentrating the budget on the creative producing results on the event you send back, and it can still move that budget later as the winner fades. We very rarely turn ad creatives off for that reason: Meta knows what it is doing. The six angles write-up from the first video makes the same point from the other side: Meta pushes the spend to the ten to fifteen percent of ads that work, and starving the rest is the algorithm doing its job.
The one reason to turn it off
A true winner is not the ad with the cheapest leads; it is the ad whose leads fund. It is easy to get caught up in the numbers in the ads manager and celebrate the creative producing $10 leads all day, when those leads are bad and nothing is funding. That is not a winner. If Meta is still sending that ad the whole budget, switch it off and use your own judgement over the algorithm’s. Plenty of leads is the first step of a winner; the test of one is what funds.

The winner will not last
The ad that works today will not work in two months. The more you spend, the sooner it fatigues, because it is shown to more people more often, and the burn scales roughly one to one: double the spend, double the creatives. So the time to replace the winner is while it is still winning. Make ten variants of it before it dies, and keep the creative pipeline sized to the budget.
Questions brokers ask
Why is Facebook spending all my budget on one ad?
Because it found the ad that converts on the event you send back, and it concentrates spend there. On our campaigns one or two ads take about 90% of the budget within a day or two. That is normal, and you should leave it.
Should I turn off Meta ads that are not getting any spend?
No. Meta can shift the budget to them as the winner fades, and turning them off takes that option away. We very rarely turn creatives off.
When should I turn off a winning Facebook ad?
When its leads do not fund. An ad producing $10 leads all day that never turn into deals is not a winner, however good it looks in the ads manager. Switch it off, and check what the pixel is being told.
How long does a winning MCA ad last?
About a month or two, and less the more you spend. Have variants of it running before it dies rather than after.
What makes an ad a true winner?
Funded deals. Plenty of leads is the first step, but the winner is the ad whose leads end up collecting you money, not the one with the lowest cost per lead.
