The lesson
Open a case study with the cast and four result numbers, then explain the campaign below for readers who keep going.
A strip of campaign character portraits runs across the top with "GUCCI" over it. Directly beneath are four big stats: 395K Total Lens Shares, 7.7M Reach with Gen AI (including 17% from Earned Reach), 178M Total Impressions and 11s Average Lens Playtime. Sections of text and a carousel of campaign phone screens follow, then a "READY TO START YOUR SNAPCHAT SUCCESS STORY?" banner.
Don't copy the fashion cast or the lens-specific metrics. Keep the stats row directly under the hero and a footnoted source for the numbers.
