- Left out a key finding
- Drew a conclusion from a figure without its caveat
- Made a material claim the analysis does not support
In detail
- Caveat missing: TikTok's CAC comes from a three-week, £60k test measured on last click.
- Slide 2: “Reallocating that £360k funds increases of £180k to paid search, £250k to CRM and referral, and £90k to TikTok.” is not supported by the analysis.
- Slide 2: “The proposed recipients, including TikTok, are channels with proven efficiency.” is not supported by the analysis.
- Slide 6: “Paid Search faces diminishing returns.” is not supported by the analysis.
- Slide 6: “CRM and referral spend triples.” is not supported by the analysis.
- Slide 6: “Around 35,000 new customers in H1 2026 vs. 25,700 in H2 2025 (assuming H2 CACs hold)” is not supported by the analysis.
- Slide 5: chart 2: 9 pt.
- Finding missing: TikTok's £50 CAC comes from a small test, and its customers spend about half what Meta's do.
