TikTok is over-indexed on spend relative to conversions. It consumes 57% of budget but delivers only 50.5% of conversions, at the highest CPA ($11.00). Facebook shows the opposite pattern — 14% of spend driving 17.9% of conversions. Consider reallocating 5-10% of TikTok budget toward Facebook retargeting, which has a $5.95 CPA.

Across the 30-day period, the three-channel portfolio spent $130,245 to generate 13,363 conversions at a blended $9.75 CPA. Google Search Brand and Facebook Retargeting are the efficiency leaders at $5.10 and $5.95 CPA respectively — these are proven, intent-driven channels that should be scaled first. Google Generic Search is the outlier at $24.80 CPA — keyword refinement and negative keyword expansion would likely bring this in line. TikTok delivers massive reach (28.7M impressions, 71% of total) at the lowest CPM ($2.59), making it ideal for top-of-funnel awareness. Its 26% video completion rate suggests strong creative resonance, but the conversion path needs optimization to justify its 57% spend share. Action items: (1) Shift 10% of TikTok budget to Facebook Retargeting, (2) Audit Google Generic Search keywords, (3) Test TikTok-to-landing-page funnel improvements.
