Get an explainable score before refreshing creative or changing delivery. Free performance diagnostic · browser-only # Is the ad fatigued, or did performance move for another reason? Compare two periods across frequency, click-through rate, cost per acquisition, return on ad spend, and reach. The calculator produces an explainable risk score—not a magic cutoff. [Check fatigue risk](https://marketmaster.dev/ai-ad-fatigue-checker#checker)[Build a fresh campaign](https://marketmaster.dev/studio) The diagnostic pattern **Fatigue is a trend across metrics.** Rising repetition becomes more persuasive when attention, reach, and business efficiency weaken at the same time. **Frequency ↑** + **CTR ↓** + **CPA ↑** = **Refresh signal** On this page [Calculator](https://marketmaster.dev/ai-ad-fatigue-checker#checker)[Interpret](https://marketmaster.dev/ai-ad-fatigue-checker#interpret)[Refresh](https://marketmaster.dev/ai-ad-fatigue-checker#refresh)[Mistakes](https://marketmaster.dev/ai-ad-fatigue-checker#mistakes)[FAQ](https://marketmaster.dev/ai-ad-fatigue-checker#faq) 01 · Compare equal periods ## Calculate ad fatigue risk. Use two comparable windows: for example, the last seven complete days versus the previous seven. Do not compare a launch weekend with an ordinary weekday period. Prior frequency _[Input: 2.1]_ Current frequency _[Input: 3.8]_ Prior CTR (%) _[Input: 1.8]_ Current CTR (%) _[Input: 1.3]_ Prior CPA _[Input: 32]_ Current CPA _[Input: 44]_ Prior ROAS _[Input: 3.2]_ Current ROAS _[Input: 2.4]_ Prior reach _[Input: 28000]_ Current reach _[Input: 23000]_ **Action:** Calculate fatigue risk Values stay in your browser. The score is directional and does not replace platform attribution or experiment design. **Fatigue risk** · 0–100 **0** / 100 Enter comparable periods - Complete the metrics you have; missing metrics are ignored. 02 · Read the pattern ## What counts as ad fatigue? TikTok’s current auction guidance identifies the same directional pattern used here: CTR trending down while frequency rises, impressions or reach trending down, and CPA rising or ROAS falling. TikTok also describes a platform Fatigue Index, but that proprietary score is not reproduced by this calculator. First-party reference: [TikTok Web Auction Best Practices](https://ads.tiktok.com/business/library/TikTok_WebAuctionBestPractices.pdf). Meta separately recommends creative diversification across formats, placements, and visual concepts in its [ad creative guidance](https://www.facebook.com/business/ads/ad-creative). 03 · Refresh the idea ## What should I change when an ad is fatigued? Create meaningful variation. Changing a background color while preserving the same hook, proof, and scene may look new in a file directory but feel identical to the audience. **Hook** ### Open on a different tension Move from aspiration to objection, from outcome to mechanism, or from a broad promise to a specific moment of use. **Evidence** ### Show a different receipt Rotate between product demonstration, customer language, quantified proof, process evidence, and a clear limitation or tradeoff. **Format** ### Change how the idea is consumed Turn a static benefit claim into a demonstration, comparison, founder explanation, customer story, or sequenced carousel. **Audience** ### Match a different buying situation Keep the product truth stable while speaking to a distinct trigger, awareness level, objection, or job to be done. 04 · Diagnostic guardrails ## Do not blame creative for every performance decline. Fatigue is only one hypothesis. Before replacing a working concept, check whether the comparison changed for reasons unrelated to repeated exposure. **Possible confounders** ### Conditions changed - Budget, bid strategy, attribution window, or optimization event changed. - Inventory, price, promotion, landing page, or tracking changed. - The audience narrowed, seasonality shifted, or a competitor entered. - A small sample made ordinary variance look dramatic. **Stronger fatigue evidence** ### Exposure and response moved together - The same concept served repeatedly to substantially the same audience. - Frequency rose while CTR and reach weakened over comparable periods. - CPA or ROAS deteriorated without a corresponding funnel change. - A materially different creative recovers performance in a controlled test. FAQ ## AI ad fatigue questions. ### Does AI cause ad fatigue? No. Repeated exposure and declining response cause fatigue. AI can produce more files quickly, but shallow variations may repeat the same concept. ### What frequency is too high? There is no universal cutoff. Audience size, purchase cycle, placement, objective, and creative strength all matter. Interpret frequency alongside CTR, reach, CPA, and ROAS trends. ### Should I turn off a fatigued ad immediately? Not always. Add new creative before removing coverage when possible, then compare the new concept under similar delivery conditions.
