What is the difference between a mobile billboard and DOOH?

DOOH (digital out-of-home) usually refers to fixed digital screens and billboards in set locations. A mobile billboard truck is a moving digital screen that drives custom routes, so it adds targeting and event flexibility that fixed DOOH cannot match.

Do I get the whole screen with a mobile billboard truck?

Yes. For your campaign, the truck's screens are 100% yours. Fixed digital billboards often rotate your ad in a shared slot with other advertisers.

Can I use both mobile and fixed digital billboards?

Absolutely. They complement each other: fixed DOOH for mass reach at key sites, mobile trucks for targeted, full-screen, street-level presence around events and neighborhoods.

Mobile Billboard vs Digital Billboard (DOOH)

A mobile LED billboard truck drives your digital ad on custom routes to where your audience is, while a fixed digital billboard (DOOH) displays your ad in one premium location to everyone who passes. Mobile trucks win on targeting, event flexibility, and street-level reach; fixed DOOH wins on raw impressions at a single high-traffic site and programmatic buying.

Side by side

	Mobile Billboard	Digital Billboard
Mobility	Routes anywhere you choose	Fixed location
Targeting	Follows audiences, events, and neighborhoods	Reaches one location's traffic
Creative	Full-motion video, change anytime	Full-motion video, often shared with other advertisers in rotation
Share of screen	100% yours for the campaign	Often a rotating slot shared with other ads
Reach	High along busy routes and events	Very high at premium fixed sites
Buying	Direct, per truck per day	Often programmatic (pDOOH) by impression
Best for	Targeted, event-driven, street-level campaigns	Mass reach at iconic fixed locations

When to choose mobile billboard

Choose a mobile billboard truck when you want 100% share of screen, the ability to follow your audience to specific events or neighborhoods, and street-level presence the fixed network cannot reach. It is ideal for activations, launches, and local domination.

When to choose digital billboard

Choose fixed digital billboards when your goal is maximum raw impressions at an iconic, high-traffic location (a highway, a city square) and you are comfortable sharing the screen in rotation with other advertisers, often bought programmatically.

The verdict

The two are complementary. Fixed DOOH delivers mass reach at landmark sites; a mobile billboard truck delivers targeted, full-screen, street-level presence that follows your audience. Many strong campaigns use both, and PixelMile can coordinate the truck side of that mix.
