CTR Equivalent for DOOH 2026: 4 Honest Engagement Metrics

TL;DR

DOOH has no click. We use four proxies instead: QR scans (0.03–0.15%), branded search lift (8–25%), geofence footfall and direct traffic spike. Anyone promising more is making numbers up.

Why DOOH has no real CTR

The online CTR measures view → click → landing page. DOOH doesn't work that way. Someone sees a screen, walks past, googles your brand two hours later. That is engagement — but not click-based.

The industry agreed on proxy metrics. None is perfect. All four together give a reliable picture.

The 4 honest engagement proxies

1. QR Scan Rate

Scan Rate = (Scans / Impressions) × 100

Benchmarks (DACH 2025): Indoor 0.08–0.15%, Outdoor 0.03–0.06%, Premium 0.12–0.20%.

Example: 50,000 impressions × 0.1% = 50 scans. Anyone promising 1% has a typo or counts views as scans.

2. Branded Search Lift

Lift % = ((Searches during campaign / Baseline) - 1) × 100

Tools: Google Trends (free, rough), Search Console (own brand, precise), SISTRIX/SEMrush.

Realistic values: Local SMB campaign 8–15%, mid-size 15–25%, large >€10k 25–60%.

Caveat: Always compare year-over-year, not month-to-month, to remove seasonality.

3. Geofence Footfall

Footfall Lift = ((Exposed visitors / Control) - 1) × 100

Providers: Adsquare, Mfind, hivelink. Usually €50k+ minimum spend. Workaround for small budgets: own door counter or POS data, compared YoY.

4. Direct Traffic Spike

GA4 → Acquisition → Direct. Filter by region, device, new-user % to clean noise.

Combined SMB setup

Composite:

Engagement = (Eurobetrag nicht öffentlich beziffert) + (Search Lift % × Baseline Value)
           + (Footfall × AOV × 0.3)

The 0.3 is typical visit-to-customer conversion. Premium hospitality 0.5, impulse retail 0.15.

What NOT to measure

‘‘Eyes on screen’’ without cameras = guess, not measurement
Black-box ‘‘engagement scores’’ = marketing theater
CTR promises >0.5% = mathematically impossible on legitimate DOOH inventory
