Lead-magnet prompt · free

I want a creative fatigue report for my Meta ad account act_XXXXXXXXXX. Use these signals to classify every ad with >$500 spend in the last 21 days:

1. CTR decline — compare last 7 days vs previous 7 days. >20% drop = fatigue signal.
2. Frequency creep — average frequency in the last 7 days. >4.0 = fatigue signal.
3. CPA increase — last 7 days vs previous 7. >25% increase = fatigue signal.
4. CVR decline — last 7 days vs previous 7. >15% drop = fatigue signal.
5. Spend shift — has Meta pulled spend away from this ad week-over-week? Yes = late-stage fatigue signal.

Classify each ad as:
- HEALTHY (0-1 signals)
- EARLY WARNING (2 signals)
- FATIGUED (3 signals)
- DEAD (4-5 signals or already paused by Meta optimization)

Return a structured table grouped by status. For every FATIGUED and DEAD ad, generate a refresh brief with:
- The ad's hook, format, persona
- Why it's fatigued (cite the signals)
- 3 specific refresh angles to test (new hook, new visual treatment, new persona angle)

Then output a paste-ready prompt I can give to Higgsfield (for video regen) or ChatGPT (for image regen) to produce the refresh creatives.

What you get back

Format: Markdown table grouped by status (HEALTHY / WARNING / FATIGUED / DEAD), plus per-ad refresh briefs

Sample output

Ad ID Status Signals Refresh angles
120201234... FATIGUED CTR -32% · Freq 4.8 · CPA +41% 3
120201567... EARLY WARNING Freq 4.2 · CPA +28% 0
120201890... HEALTHY none 0

Next step: Pipe the FATIGUED refresh briefs to Higgsfield MCP for AI video regeneration, or to ChatGPT for image refresh.

Variations

Cross-channel version

Add Google Ads to the same prompt. GoMarble's hosted MCP runs the same fatigue logic against Google Ads creative if it's a Demand Gen or PMax with creative assets.

Scheduled weekly run

Move from a one-off prompt to a recurring weekly job via GoMarble's Agent Mode. Get the fatigue report in Slack every Monday morning.

Hook-pattern overlay

Cross-reference fatigued creatives with their hook archetype (sensory_demo / transformation / problem_statement / direct_address / concept_reframe). Identify which hook types are fatiguing fastest.

Want this automated?

Run the prompt above every Monday morning automatically. GoMarble's Agent Mode + scheduled jobs deliver the report (Slack / email / in-app) without re-prompting Claude. No more manual checks.

Frequently asked

How does this work without performance data in the API?
GoMarble's MCP pulls live performance data via facebook_get_adaccount_insights — CTR, CPM, CPA, ROAS, frequency, all with attribution window control. Then the prompt does the week-over-week comparison and classification logic.
Why >$500 spend threshold?
Ads under $500 in a 21-day window often don't have enough impressions for week-over-week metrics to be statistically meaningful. Lower the threshold if you run smaller-budget tests, but expect noisier signals.
What if I don't have Higgsfield or ChatGPT for creative refresh?
The fatigue classification works on its own. The refresh briefs are written in plain English — paste them into any creative tool, send to your creative team, or run through Claude with image-gen tools. Higgsfield MCP is just the most automated path.
Can I run this on a schedule?
Yes. Once you've connected GoMarble's MCP, enable Agent Mode in GoMarble's web dashboard and set this prompt to run weekly. You'll get the report delivered (Slack, email, or in-app) every Monday morning without re-prompting Claude.
Does this work on TikTok or Google Ads creatives?
The fatigue logic generalizes — CTR drop, CPA creep, frequency creep all apply across platforms. GoMarble's MCP exposes equivalent tools for TikTok (tiktok_get_basic_report_enhanced) and Google (google_ads_run_gaql). Modify the prompt to target tiktok_ or google_ads_ tools, or run the same prompt against multiple ad accounts at once.
