Persona Analysis
Winners Ad Set — Static85_H137_v2 Dominance
Static85_H137_v2 (WaistMatch AILifestyle) has become the dominant spend vehicle in the Winners ad set — £76 spend this week vs £14 in W23. The algorithm has shifted budget decisively to this creative. Static90_v4 (OpticWhite) is getting near-zero spend (£0.43) — the algorithm has deprioritised it in favour of WaistMatch. This is a significant structural shift: the account's primary TOF creative is now the WaistMatch angle, not OpticWhite.
Static85_H137_v2: £76 spend — algorithm's dominant choice | Static90_v4: £0.43 — effectively paused by algorithm
P1 — Fit Transformation Seeker (Marilyn W24 NEW)
Static107_v3 (AISplit-Screen) continues to be the P1 ad set anchor — £60 spend, 6.86% CTR. The new W24 creatives (Static108 BeforeAfter, Static109 WaistMatch Measurement) are in early learning. Static109_v1 has 6.90% CTR on £5 spend — strong early signal for the WaistMatch Measurement angle. Static108_v3 is getting the most spend among new creatives (£9 spend). The algorithm is still distributing budget across variants to learn.
Static107_v3: £60 spend, 6.86% CTR — P1 anchor | Static109_v1: 6.90% CTR early signal
P2 — Effortless Style Upgrader (Capri)
The P2 ad set is being deprioritised by the CBO algorithm — all P2 creatives are getting minimal spend (under £2 each). Static104_v4 was the W23 winner at 4.13x ROAS; this week it has near-zero spend. The algorithm has moved budget to the Winners ad set (Static85) and P1 Marilyn. This is correct CBO behaviour — the algorithm found better-converting creatives and concentrated budget. Do not intervene in the P2 ad set.
P2 ad set: algorithm deprioritised — all variants under £2 spend | CBO is correctly concentrating on Winners + P1
Bid Cap — Charlotte UGC + Static86 WaistMatch
The Bid Cap campaign has a new Charlotte UGC retest (Retest_2) spending £29 alongside the original Charlotte UGC (£67). Charlotte UGC01 Hook03_v3 is the dominant spend vehicle at £67 — 1.47% CTR, low engagement but the bid cap is finding purchases efficiently. Static86_v1 (WaistMatch BeforeAfter) is at £23 spend with 2.12% CTR — still running in the 26W15 ad set. The Bid Cap is the most efficient campaign structure in the account when Charlotte UGC converts.
Charlotte UGC01: £67 spend, 1.47% CTR | Static86_v1: £23 spend, 2.12% CTR | Retest_2 UGC: £29 spend
Action Points
-
🔴
CHECK purchase data on Charlotte UGC01 in Bid Cap — decision needed Charlotte UGC01 has now spent £67 this week. The API is not returning purchase data for the Bid Cap campaign. Check Ads Manager directly: if Charlotte UGC01 is generating purchases at above 3x ROAS, protect it. If 0 purchases at £67+ spend, pause it today. This is the most important data check in the UK account this week.
-
🔴
PAUSE Static107_v1/v2/v4/v5 in P1 Marilyn ad set The algorithm chose Static107_v3 in W23 and it's holding at £60 spend this week. v1/v2/v4/v5 are getting minimal spend. Pause all non-v3 Static107 variants to concentrate budget on the winner and give the new W24 creatives (Static108/109) room to be evaluated cleanly.
-
🟡
MONITOR Static85_H137_v2 — new dominant spend vehicle The algorithm shifted £76 to Static85 this week. This is a structural change from W23. Check purchase data in Ads Manager — if Static85 is converting at above 3.5x ROAS at £76 spend, this becomes the priority scale candidate. If ROAS is below target at this spend level, investigate the landing page for the WaistMatch angle.
-
🟡
MONITOR Static109_v1 (WaistMatch Measurement) — 6.90% CTR early signal First week live, £5 spend, 6.90% CTR. Do not touch it. Give it until end of W25 to build spend and generate purchase data. If it holds above 5% CTR at £30+ spend and generates purchases, brief 3 new WaistMatch Measurement variants immediately.
-
🟡
BRIEF new UK Retargeting static creative — single point of failure The Bestselling SS26 Dynamic is the only active retargeting ad (£140 spend). The MOF Trousers statics are paused. If the dynamic fatigues or the product goes out of stock, the retargeting campaign has nothing to fall back on. Brief a new MOF static with a review/social proof angle for the retargeting audience.
-
🟢
BRIEF 2 new Static107_v3 iterations (Marilyn AISplit-Screen) Static107_v3 is the confirmed P1 anchor — £60 spend, 6.86% CTR across two weeks. Brief 2 new iterations: (1) Same split-screen format, new headline — "Wide leg. Narrow waist. No compromise." (2) A video version of the split-screen — 6-second loop, same visual world. These are the highest-probability new briefs for the P1 persona.
-
🟢
BRIEF P1 Marilyn UGC for UK — highest priority new concept The Marilyn AI creatives are working. The next step is UGC validation. Brief a UK-based creator (40–55, professional woman) to film a 30–45 second talking-head: "I've been wearing the wrong jeans for 20 years." Show the Marilyn fit on camera. Authentic, no script feel. This is the single highest-ROI brief you can make for the UK account right now.
Creative Iteration & New Concept Ideas
Iterate: Static107_v3 (P1 Marilyn AISplit-Screen) — Confirmed Anchor
- New headline: "Wide leg. Narrow waist. No compromise." (functional transformation)
- New headline: "The Marilyn cut. For women who stopped settling." (identity/aspiration)
- Test a 3-panel version: before / waist detail / full outfit (add context)
- Brief a video loop: 3-second before → 3-second after, no voiceover, music only
- Add a social proof overlay: "47,000 women found their perfect fit" on the split-screen
Iterate: Static85_H137_v2 (WaistMatch AILifestyle) — New Algorithm Winner
- New headline H138: "Your waist size doesn't change. Your jeans should know that." (guarantee)
- New headline H139: "Jeans that fit your waist first. Everything else follows." (priority angle)
- Test a before/after version of the WaistMatch concept — show the fit difference
- Brief a UGC version: creator demonstrates the waist-match fit on camera
- Test a product-forward version: close-up of the waistband with measurement overlay
New Concept: P1 WaistMatch Measurement (Static109 Scale Play)
- Static109_v1 has 6.90% CTR in its first week — the Measurement visual is working
- Brief 3 new variants: different measurement angles (waist, hip, inseam)
- New headline: "Finally, jeans sized for your actual measurements" (precision angle)
- New headline: "Measure once. Wear forever." (simplicity + permanence)
- Test a split-screen: measurement tape on waist (left) / perfect fit result (right)
New Concept: UK Retargeting — Social Proof Static
- The Bestselling Dynamic is the only retargeting vehicle — needs a static backup
- Brief: "You've seen these. Here's what 4,200 UK women said." (review retargeting)
- Format: Product image with 3 real review quotes overlaid — no model, product-forward
- Angle: Urgency + social proof — "Limited sizes remaining in your browsed styles"
- Persona: MOF — someone who visited the site, browsed jeans, did not convert
New Concept: Charlotte UGC — New Hook Direction
Charlotte UGC01 Hook03_v3 has been running since W02 (February). It has generated purchases but the CTR is 1.47% — low for a UGC format. The hook is the problem, not Charlotte. Brief a new Charlotte UGC with a different hook direction: instead of a review hook, try a demonstration hook — "Watch me find my perfect fit in 30 seconds using NYDJ's waist measurement system." This connects the UGC format to the WaistMatch angle that the algorithm is currently favouring. Same creator, new hook, new concept.
