Advertisers that added new creative every week achieved 23% higher return on investment than those that refreshed creative only once or twice, according to new data on Black Friday ad spend optimization.

The finding lands as brands finalize budgets for the year's biggest retail window. Twenty-three percent is not a marginal gain. For an advertiser spending $1 million on peak-season media, the gap between a weekly creative cadence and a one-or-two-time refresh translates into a return difference worth roughly $230,000 in effective media value, based on the reported ROI uplift.

What does the number actually measure?

The comparison pits two cadences against each other. On one side: advertisers adding new creative weekly. On the other: advertisers adding creative only once or twice over the measured period. The 23% ROI advantage belongs to the weekly group.

Creative frequency, in other words, functioned as a performance lever independent of the spend level itself. The data suggests the same budget works measurably harder when the assets behind it rotate on a weekly rhythm rather than sitting static through the funnel.

Why does this matter ahead of Black Friday?

Black Friday compresses a year's worth of competition into days. Auctions crowd. Audiences see the same ads repeatedly. Fatigue sets in fast, and a stale asset burns impressions without converting.

Weekly refreshes counter that decay. Each new creative reset gives the algorithm fresh material to explore and gives viewers a reason to look again. The 23% figure quantifies what many performance teams have assumed: the marginal ad dollar increasingly depends on the marginal asset.

The takeaway in plain words: before adding budget, add creative.

What should advertisers do with this?

The data points to a clear operational checklist for the run-up to peak season:

• Audit current creative libraries and identify how many weeks of fresh assets exist
• Set a weekly production cadence now, not mid-campaign when fatigue has already cost conversions
• Treat creative volume as a budget line, not an afterthought
• Measure ROI by creative cohort to confirm the weekly-cadence effect in your own account

Brands that cannot sustain weekly production internally face a build-or-buy decision before November demand peaks.

The so-what

The 23% ROI gap separates advertisers not by how much they spend but by how often they refresh what they spend it on. As Black Friday approaches, the data makes the priority explicit: weekly creative is the cadence to beat.
