Creative fatigue

Creative fatigue (also called ad fatigue) is when an ad slowly loses effectiveness because the same group of people has seen it too many times: they scroll past faster, engage less, and your cost per result goes up.

What is creative fatigue?

Meta defines creative fatigue as an audience having seen the same creative too many times, which makes them less likely to engage and can push up cost per result. In its assessment, Meta counts every recent impression of the same image or video, including impressions from other campaigns run by the same Page (Meta Business Help Center, About creative fatigue recommendations). Duplicating a video into a new campaign does not make it “new” in the system’s eyes.

A fatigued ad is not the same as a bad ad. A bad ad underperforms from the start. A fatigued ad used to work and then declined.

How do you spot creative fatigue?

In Meta Ads Manager, the Delivery column can show two statuses, based on comparing cost per result with ads you’ve run before:

If Meta predicts that an ad will fatigue within its first 7 days, it warns you before you publish. This only applies to ad sets with a single creative, and some types are excluded, such as Advantage+ catalog ads and dynamic creative.

Don’t rely on platform labels alone. Track a few numbers weekly: frequency going up, CTR going down, hook rate going down while CPM climbs. Ad relevance diagnostics can also help you narrow it down: Meta reads a below-average engagement rate ranking as a sign that the ad failed to spark interest (Meta Business Help Center, How to use ad relevance diagnostics).

How do you fix creative fatigue?

Meta suggests three options: build new ads with images or videos that are clearly different from the original, broaden the audience to reach people who haven’t seen the ad much, or use Advantage+ creative. Meta also notes that keeping the old ad running alongside the new ones, rather than switching it off, can produce better results.

TikTok recommends refreshing creative when delivery results keep declining, and adding new creatives to the ad group that is already running instead of creating a new ad group, so the ad group lasts longer. Each ad group should have 3 to 5 clearly distinct creatives (TikTok Business Help Center, Creative best practices for performance ads, June 2025).

“Clearly different” is the part that matters most. Changing the text color or the headline on the same video is usually not enough, because Meta’s system may treat near-identical versions as one ad. The variation has to come from concept, persona, format and hook.

Example (hypothetical)

A fashion shop runs a “5 outfits from 1 pair of pants” video on Meta. For the first three weeks, cost per order is around VND 110,000, in line with its earlier ads. In week five, frequency reaches 4.2, CTR falls from 1.6% to 0.9%, and cost per order hits VND 240,000, more than double the old level. Ads Manager shows “Creative fatigue.” The shop keeps the old video and adds two new concepts: one of real customers trying on clothes in the fitting room, and one comparing fabrics. Then it watches whether the ad set’s overall cost comes back close to where it was.

Frequently asked questions

How long does it take for a creative to fatigue?

There is no universal number. The smaller the audience and the bigger the budget, the faster it wears out. Compare against your own account’s history instead of trusting a fixed number you read online.

Should you turn off a fatigued ad right away?

Not necessarily. Meta says keeping the original ad running can maximize results. Add new creatives first, then let the data decide how budget is split.

If many ads in your account are flagged as fatigued and you need a monthly creative refresh plan, Adtek’s Creative Strategy team can look at it with you. Reach us through the contact page.
