"How many ads do we need?"

It's one of the questions I get asked most. Usually it comes with an assumption baked in: that the answer is more. More ads, more variations, more output from the creative team.

And that isn't wrong. But it's only half the answer.

Why volume on its own stopped working

Meta now decides who sees an ad largely by looking at the ad itself: the message, the visuals, the format, who it seems to be for. Your creative is doing most of the targeting.

That has a knock-on effect people miss. If you make ten ads that all say the same thing in slightly different colours, Meta treats them as close to the same ad, and shows them to the same people. You've paid for ten ads and bought yourself one.

Ten versions of the same idea is one ad. Ten different ideas is ten chances to reach someone new.

How I forecast creative volume

I still think it's worth putting a number on it, because "make more ads" isn't a plan. This is the sum I start with:

Spend per test = target CPA × X
Ads you can test = testing budget ÷ spend per test

X is how many purchases' worth of spend you're prepared to give a new ad before you judge it. Set it based on your margins and how noisy your data is.

As an illustration: with a target CPA of £30 and an X of 3, each new ad needs about £90 to get a fair test. If your monthly testing budget is £4,500, you can properly test around 50 new ads a month. Make 150 and most of them never get enough spend to tell you anything. Make 10 and you're leaving learning on the table.

Where the sum falls down

It's a starting point, not the full picture. It doesn't account for two things that matter a lot:

  • Hit rate. Most ads won't work. Motion's 2026 benchmark of more than 550,000 Meta ads found only around 6% of ads drive most of the spend in an account. You need enough shots to find the few that land.
  • Your ability to scale winners. One great ad that can take serious budget is worth more than twenty decent ones that can't.

So I use the sum to set the ceiling for testing, then judge the creative plan on how varied it is, not how big it is.

Growth ceilings are usually angle problems

When a brand stalls, the first instinct is often to look for a new channel. In my experience, the ceiling is far more often a lack of new angles. The account keeps talking to the same person about the same reason to buy.

An angle is a different way into the product: a different customer, a different problem, a different desire or a different objection to answer. Map them out and the gaps become obvious.

Most accounts I look at only ever fill one or two of these boxes. The gaps are where new customers are.

Filling those gaps does more for growth than another round of variations on the ad that's already working.

The loop that keeps it going

This is the part I care about most. A good creative system isn't one big burst of output. It's a loop that runs every week, where each round of results makes the next brief better.

Research Brief Produce Test Learn One loop every week
Every round of testing should make the next brief sharper.
  • Research: reviews, comments, competitors and your own data, looking for angles you're not using yet
  • Brief: clear concepts, each built around one angle for one type of customer
  • Produce: a mix of formats, so Meta sees genuinely different ads
  • Test: with enough spend per ad to get a real answer
  • Learn: what worked, why, and what that tells you to try next

Run that every week and the account gets smarter over time, instead of starting from scratch every month.
