Method and limits

  • Source: Meta Ad Library API (ads_archive, all statuses). Every ad the brands' pages delivered in SE, NO, DK, FI, DE, GB between 1 Oct and 5 Dec 2025, pulled 21 Oct 2026. Ads that left the Library before then (about a year after they last ran) are missing.
  • Black Week ads: copy that names Black Week, Black Friday or Cyber Monday (six languages), plus ads with an offer (discount, sale wording) that started in the Black Week period, 17 Nov to 1 Dec. Catalogue ads with product-only copy read as neither.
  • Lift compares new ads per day, not budget. The Library has no spend, daily impressions or results for commercial ads, so nothing here says what was profitable.
  • Discounts count only percentages in discount context (“-30%”, “30% off”, “up to 50%”). Reach is Meta's EU reach estimate.
  • Retailers are measured on their Swedish pages. Outside the EU and UK the API returns no commercial ads, so US programmes (Gymshark, AG1, Hismile, Oura) aren't here.
