Why it is not presentable

  • Layout defect: something off the slide, colliding, too small or too faint to read
  • Left out a key finding
  • Did not give the analysis's recommendation within the first two slides
  • A slide the judges rated as needing work

In detail

  • 2 slides; the brief allows 5-8.
  • Finding missing: CRM and referral is the most efficient channel (CAC £40, 90-day ROAS 5.12) and can take more budget.
  • Finding missing: Paid search is the largest efficient channel (ROAS 2.48) with room to grow.
  • Finding missing: Display returned £0.79 per £1 in 90 days and a holdout test found no measurable lift.
  • Finding missing: TikTok's £50 CAC comes from a small test, and its customers spend about half what Meta's do.
