Why is creative testing the biggest lever in performance marketing?

Targeting and bidding have consolidated. On Meta and TikTok in particular, creative is now responsible for the majority of variance in CAC and ROAS.

How many ads should a brand test per month?

For a scaled DTC brand, 20–40 concepts per month is a healthy cadence. The discipline of briefs, reads and iteration matters more than raw volume.

How long should an ad run before you kill it?

Give a new ad enough spend to reach statistical honesty — usually 3–5x target CPA on Meta, or a defined impression floor on Google and TikTok — before judging it.

Do you need in-house creative or can agencies do this?

Either can work. What breaks the model is producers who do not sit inside the same weekly brief, launch, read and iterate rhythm as media buying.
