⚡ Insight: View → Purchase = 85.5% Conversion

8,233 Verified Views (mandatory brand video played during checkout, 100% VCR) → 7,040 completed purchases = 85.5% conversion rate. Meanwhile, 92% of buyers did NOT click the ad (only 542 Interacted vs 7,040 purchases) — they saw the video repeatedly in the loop → built brand recall → chose to buy on their own. This is the Brand Awareness Effect — non-skippable DOOH creates natural brand recognition.

3. 4-Tier Measurement Framework: Closed-Loop Measurement

Unlike traditional DOOH which can only measure video plays (impressions), Dropfoods measures the entire journey from display → interaction → verified view → purchase at the point of sale.

📊 4-Tier Measurement Framework

  • 🥉 D-Spots — Video/banner played in the loop cycle (ambient impression), with or without a direct viewer. Automatically tracked by the system.
  • 🥈 Interacted — Active engagement: ad clicks, game plays, surveys, QR scans. Applies to both Type A + B.
  • 📺 Verified Views — Brand video plays directly during checkout → buyer must watch the full video before completing the transaction. VCR = 100%.
  • 🥇 Verified Purchases — Verified orders: watched brand video → purchased the product at the machine. Type A only.

💡 Key Message for Brands

"Don't compare cost per view — compare cost per purchase. Dropfoods delivers at 3,636 VND/purchase vs. Facebook 50K–200K, YouTube 70K–300K. Dropfoods is 14–82× cheaper and the transaction happens right at the point of display."

7. Two DOOH Product Types on Dropfoods

📦 Type A vs Type B

  • Type A — DOOH + Product on Machine: For brands WITH products sold on the machine. Video ads combined with direct sales → measures D-Spots + Interacted + Verified Views + Verified Purchases (closed-loop).
  • Type B — Pure DOOH (Ads + Interaction): For brands WITHOUT products on the machine (banks, insurance, apps...). Ads combined with games/surveys/QR → measures D-Spots + Interacted.

The Holland Water campaign is Type A — the product is placed directly in the machine, creating a closed loop from viewing the ad → watching the brand video → purchasing.
