When should you refresh ad creative?

What is creative fatigue and how do ad platforms report it?

According to Meta's Marketing API documentation, creative fatigue rises as an audience sees the same creative repeatedly. Meta says it usually shows up as a falling click-through rate and a rising cost per action.

Meta reports creative fatigue as a level. Its creative_fatigue webhook notifies developers when an ad's creative fatigue level changes, and the level is LOW, MEDIUM or HIGH. If you run Meta ads through the API, that level is a direct signal. If you work in Ads Manager only, the sources cited here don't describe where the level appears there.

TikTok treats creative fatigue as something its system can detect. Per TikTok's help center, Smart Creative is an automated creative solution that works through ad group fatigue detection and auto-refresh strategies. TikTok says its anti-fatigue refresh pauses initial videos that show signs of fatigue within the first 3-5 days and puts new videos on a waiting list.

That window describes how Smart Creative tests its own videos. Read it as a feature detail, not as a refresh schedule for TikTok ads in general.

Which signals show an ad needs a creative refresh?

An ad needs a creative refresh when its delivery or engagement numbers decline over time. TikTok's help center names two signals: delivery results that show a consistently declining trend, and low daily new users. TikTok recommends checking ad performance regularly and refreshing ad group creatives when either appears.

TikTok's creative guide adds another reading. If engagement or CTR drops over time, the guide says to refresh your ad creative. It also says even a new opening or caption can improve performance, so a refresh doesn't always mean a new concept.

On Meta, the signals overlap. According to Meta's developer documentation, creative fatigue usually shows up as a falling click-through rate and a rising cost per action. Meta suggests reading frequency and CTR day by day to see the shape of the decay, and cost per action to see how much more expensive the ad is getting.

Both platforms describe a trend over time. If CTR falls and cost per action rises, that pattern matches how Meta describes creative fatigue. TikTok's wording is a consistently declining trend, so check performance regularly.

How do the platforms recommend refreshing creative?

When you refresh creative, TikTok points to an existing ad group, and Meta's example message points to the same campaign. According to TikTok's help center, when refreshing creatives, you should add new creatives to an existing ad group instead of creating a new ad group. TikTok says this extends the ad group's lifetime.

Meta's example webhook message for a fatigued ad suggests a few routes: try creating a new ad with different images or videos in the same campaign, expanding your audience, or using Advantage+ creative. In that suggestion, the images or videos change and the campaign stays.

The size of a creative refresh can be small. TikTok's creative guide says even a new opening or caption can improve performance when engagement or CTR drops over time.

For YouTube target frequency line items, Google says to add at least as many creatives as your target frequency, if not more, to avoid creative fatigue. That's a setup rule for that line item type, not a refresh rule for Google Ads campaigns in general.

How can you stay ahead of creative fatigue?

Staying ahead of creative fatigue means having the next creative ready before the current one wears out. According to TikTok's help center, having a consistent supply of creatives to refresh is one way to keep your campaigns going. TikTok also suggests maintaining a library of creative assets so you can design new creatives more efficiently.

TikTok's blog gives the reason: even the best ads will experience creative fatigue at some point. It advises refreshing ad creative often. The sources cited here don't define "often" or give a fixed number of days.

Meta's guidance for Horizon Store app campaigns points to testing. It says frequent testing will combat creative fatigue, which can lead to rising costs when audiences have been overexposed to the same ads. That source is written for app campaigns, so treat it as context for other Meta campaigns.

Meta's example fatigue message lists Advantage+ creative as one option for a fatigued ad.

When is a creative refresh not the fix?

Meta's guidance for Horizon Store app campaigns says a narrow audience can lead to creative fatigue. According to that guidance, limiting your audience size too narrowly can increase your costs and lead to creative fatigue as the same users see your ads again and again.

Meta's example fatigue message lists expanding your audience alongside new images or videos. If your audience is narrow, widening it is a remedy Meta names next to new creative, so a creative refresh may not be the only change to make.

On TikTok, low daily new users is one of the listed signals to refresh ad group creatives. The sources cited here don't link that signal to audience size.

According to Meta's Horizon app guidance, making changes to your ad set can trigger a new learning period. Meta says this may not be desirable, especially when your ad set has accumulated valuable learnings and you are looking to scale. That line concerns ad set changes. The sources cited here don't say whether adding a new ad triggers it.
