Export winning ad scripts, feed them to Gemini, ask what elements appear in every video and in what order — the result is a replicable winning structure.

1. Le Rendez-vous E-commerce presents a case study from DHS Digital showing how a French women's health brand reduced new-customer acquisition cost by 40% in December, maintained in February, through a rebuilt persona-based creative strategy. 2. Host Danilo Duchenne is joined by Elisabetta, a DHS Digital strategist who has been managing this account for six or seven months. 3. The episode demonstrates how a structured creative process — research, ideation, production, and variant testing — can be replicated on any e-commerce brand to break through a performance plateau. 4. The account's starting state was a single Advantage Plus campaign and a remarketing campaign, with mostly mid-funnel and bottom-funnel creatives (GIFs, motion graphics, statics) and very little top-of-funnel UGC. 5. The product addresses urinary leakage, a condition affecting one in three women, with two distinct target segments: postpartum women aged 25-35 and menopausal women aged 50-60. 6. These two segments share the same core problem but require entirely different messaging, tone, and creator profiles, which the original account strategy was not reflecting. 7. The research phase used four sources: scraped customer reviews and ad comments analyzed via ChatGPT for problems, motivations, objections, and post-purchase changes; Reddit searches for the target's own language; TikTok organic content analysis via Parker tool; and competitor ad spend analysis via TrendTrack. 8. TrendTrack identified two high-spending competitor concepts worth adapting: a TV-passage format and a classic USP-plus-badge format, both of which later became winning ads when executed with the client's own founder and repositioned messaging. 9. The ideation phase was built on three angles tested against each persona: problem-solution, benefit, and product characteristics — with the postpartum-to-problem-solution combination and benefit-to-menopause combination emerging as the strongest pairings. 10. Gemini was used to extract a winning ad structure from 5-6 existing top-performing video scripts, identifying common elements and their typical sequence, producing a replicable template for all future UGC briefs. 11. A completely novel concept — a WhatsApp voice-note-style ad showing a montage of creators using the product while the brand founder narrates in an audio-message interface — became the single most important winning creative and the main driver of the NCAC reduction. 12. A hold-rate optimization example: a one-minute TV-passage variant was shortened to 40 seconds after the hold rate indicated audience drop-off; the 40-second version has been a top-performing ad since December. 13. Creator matching was a key discipline: all postpartum creators were women aged 25-35, all menopause creators were women aged 50-60 — mismatching creator age to audience was identified as a critical error to avoid. 14. The account moved from testing all new creatives in Advantage Plus to adding a separate test campaign segmented by marketing angle, allowing cleaner performance signals before promoting winning ads to the always-on campaign. 15. ChatGPT review scraping also surfaced customer age data from Google Reviews accounts (including date-of-birth information), allowing the team to validate the two personas quantitatively before doubling down on both. 16. The product operates in a health category with legal restrictions on certain marketing terms, requiring the team to find compliant positioning taglines that nonetheless performed well in conversion testing. 17. Two of the three winning ads were competitor-inspired adaptations, confirming TrendTrack-based competitor research as a reliable source of validated creative frameworks rather than unproven experiments. 18. The episode is conversational and case-study driven, with Danilo asking sequential questions that draw out specific examples and learnings from Elisabetta; the tone is practical and experience-based. 19. E-commerce performance marketers managing accounts in health, beauty, or other persona-segmented categories with stagnant customer acquisition costs will find this episode most actionable. 20. Listeners seeking quick advertising platform tutorials or those without an existing creative production process will find the episode assumes more operational context than they may have.
