Black Friday isn't won in BF week, but in the eight to ten weeks before it. A campaign that works has four phases: audience building in September/October, pre-BF hype in early November, a conversion push in BF week and a last-chance phase in December. Each phase needs its own creatives and its own storylines. As a baseline, that's 10 to 15 assets for the whole funnel, with at least 4 to 6 of them for the conversion phase alone. Creator content works phase by phase in BF campaigns: familiarity in phase 1, anticipation in phase 2, social proof with urgency in phase 3. If you go into BF cold, you pay the highest CPMs of the year to reach an audience that doesn't know your brand. If you fill your pixel now, you'll have a warm retargeting list in November that is cheaper to convert than any cold audience.
