Digital Out-of-Home (DOOH): Smart Billboards and Programmatic OOH

Out-of-home has gone digital. Digital out-of-home advertising (DOOH) puts your ad on screens in high-traffic places, from roadside digital billboards to transit, malls, airports and gyms, and lets you change it in minutes. Here's how it works and when to use it.

This guide is part of our series on billboard and out-of-home advertising in Canada.

Where you'll find DOOH

Environment	Audience mindset
Roadside digital billboards	Drivers; quick reads
Transit (stations, platforms, vehicles)	Commuters; waiting time
Malls and retail	Shoppers near purchase
Airports	Travellers, business audiences, long dwell time
Gyms, offices, elevators	Captive, specific audiences
Venues and campuses	Event-goers, students

Why brands like DOOH

• Flexibility: change creative quickly, with no printing or installation.
• Dayparting: show coffee in the morning, dinner in the evening.
• Dynamic creative: triggered by weather, temperature, time, sports scores or countdowns. ("Minus 20? Warm up with…")
• Testing: rotate versions on the same screen for clean comparisons. See how to test offline creative.
• Shorter commitments: some inventory is available for shorter campaigns.

The trade-offs

• Shared time: your ad appears in a loop with other advertisers.
• Brevity: each play is short, so creative must work instantly.
• Premium pricing in top locations.

Buying DOOH: direct vs. programmatic

Direct: book specific screens or packages with a vendor for set dates and share of time. Best for guaranteed presence in key locations.

Programmatic: buy impressions through automated platforms using targeting (location, time, audience data) and often alongside your other digital media. Good for flexibility and optimization, with less guarantee of specific screens. We'll cover the concept more broadly in programmatic advertising explained.

Creative for digital screens

• The same rules as static boards apply: brand first, about seven words, one idea. See billboard design for recall.
• Roadside digital boards generally restrict motion for safety. Check local rules and vendor specs.
• Indoor screens may allow motion and video; design for silent viewing.
• Build variations for time of day or conditions to make the most of flexibility.

Measuring DOOH

DOOH supports the same measurement methods as static OOH, plus a few extras:

• Play logs confirming when your ad ran
• Audience estimates per play or hour (in Canada, typically based on COMMB measurement), and on some screens, anonymous audience-counting sensors
• Time-matched response: web visits or searches around your plays
• Foot traffic from consented location data. See foot traffic attribution

Pair it with unique vanity URLs or QR codes on indoor screens where people can scan safely.

Dynamic creative ideas

• Weather-triggered: hot drinks when it's cold, patio specials when it's warm.
• Time of day: breakfast in the morning, dinner in the evening, late-night delivery after 9 p.m.
• Countdowns: days until a sale, event or launch.
• Live data: sports scores, wait times or inventory ("only 12 left").
• Location-specific: "3 minutes to our [neighbourhood] location."

Keep brand elements fixed across variations so recognition builds, and check each variation for legibility at a glance.

When to use DOOH

• Time-sensitive offers, events and launches
• Messages that change by time of day or weather
• Testing before committing to longer static campaigns
• Premium, high-traffic locations for short bursts

For long-running brand presence on a key route, static may still be the better value. Many campaigns combine both, and location strategy matters for each.
