Ad Platform Cost Efficiency Test: TikTok vs. Facebook

This report summarizes the findings of a $40,000 real-world expenditure test comparing the cost efficiency of advertising on TikTok versus Facebook (Meta Ads) for an existing client’s campaigns. The primary objective was to determine which platform offered a lower Cost Per Action (CPA) and therefore provided greater scalability for the client, whose daily ad budget had been scaled from $2,000 to approximately $15,000 across multiple platforms (Facebook, YouTube, and TikTok).

Key Finding: TikTok’s Cost Advantage

The test demonstrated a clear cost advantage for advertising on TikTok. The lower CPM (Cost Per Mille/1,000 Impressions) and CPC (Cost Per Click) metrics confirm that TikTok is currently operating with a less saturated ad market compared to the mature Facebook/Meta platform.

Comparative Results: Cost Per Action (CPA)

The core analysis centered on the Cost Per Action (CPA), the metric most relevant to the client’s business goals. Data was analyzed over both a single day and a one-week period for direct comparison.

Analysis of Cost Efficiency

  1. Daily Cost Difference:On the measured day, Facebook’s CPA was $140.34 higher than TikTok’s, confirming that Facebook was 57% more expensive to acquire the same action.
  2. Weekly Trend:The seven-day trend confirmed this disparity, showing Facebook’s CPA remained 44% higher than TikTok’s.
  3. Conclusion:The data supports the general observation that TikTok ads are currently at least 50% cheaper than comparable Facebook ads for this client’s specific acquisition goals. This efficiency unlocked significant budget capacity for scaling.
