What Is Out of Home Advertising (OOH)? Types, Examples & Benefits

With so many formats, out of home advertising is nearly inescapable. Simply defined, out of home (OOH) advertising—also known as outdoor advertising—includes any advertising you encounter when you leave your home and go about your daily activities. From billboards to transit ads, OOH media is designed to reach consumers on the move. 

Because these formats are placed along high-traffic routes and everyday environments, it’s no surprise that 88% of adults have noticed OOH advertising in the past 30 days.  

Why Out of Home Advertising Is So Effective

The benefits of out of home advertising are many, and marketers are beginning to realize that OOH is foundational to their campaigns, not just a nice add-on. It is a full-funnel solution affecting all parts of the customer journey.  

Marketers are increasingly recognizing that OOH advertising is not just a supplemental tactic—it’s a foundational part of the marketing mix. 

OOH works across the full funnel, influencing: 

Its ability to reach large audiences in the real world makes it one of the most powerful and trusted advertising channels available. 

Benefits of Out of Home Advertising

Out of home advertising continues to grow because of its unique advantages: 

There are four primary categories of OOH advertising, each with multiple formats: 

Billboards
Street Furniture
Transit
Place-Based

Billboards  
Large-format advertising displays found along highways, major roads, and urban areas. Billboards are designed for maximum visibility and impact.  

Street Furniture 
Includes bus shelters, benches, kiosks, and other placements in pedestrian-heavy areas. These formats reach audiences at eye level. 

Transit 
Ads placed on or inside public transportation vehicles and stations make up this OOH format. Subway station posters, bus wraps, and in-airport advertising are examples of transit ads.  

Place-Based  
These ads are targeted to specific locations such as malls, entertainment and sports venues, gyms, retail stores and restaurants. Ads are usually contextual to capitalize on the “captive” audience.  

Common examples of OOH advertising include: 

These formats work together to create consistent, high-frequency brand exposure. 

Static vs. Digital Out of Home (DOOH) 

Static OOH uses printed or painted materials, with one advertiser per display. 

Advantages include: 

Considerations: 

Digital out-of-home advertising (DOOH) uses digital screens to display rotating ads for multiple advertisers. 

Benefits include: 

DOOH can also be purchased programmatically through demand-side platforms (DSPs), allowing advertisers to: 

Focus on Billboards

Billboards, the oldest, most visible out of home format, are still among the most effective and trusted advertising methods. There are three main categories of billboard:  

Static Bulletins
Static Posters
Digital Billboards

Static Bulletins  

The “giants” of the billboard industry, bulletins are the largest and most impactful static billboard format,  per the Outdoor Advertising Association of America.  They come in two standard sizes: 14′ x 48′ and 10.6′ x 36′. Permanent static bulletins – messaging remains in a fixed location for an extended duration – are used to dominate high-traffic-volume areas. Rotary bulletins – messaging moves to different locations over the course of the contract – give broad market coverage and the illusion that a brand is “everywhere.”  Often placed on highways, interstates and main city arteries, static bulletins are impossible to ignore.  

Static Poster  

Poster billboards are great for reaching hyper-local audiences where they live, work, play or shop. Smaller in size than bulletins, they measure 10′ 4.5″ x 22′ 7.5.” Posters are incorporated into neighborhoods, business districts, and commuter roadways. Poster billboards are often used for shorter-term campaigns. Individual posters may be used directionally, to point potential customers toward a business’ location. They are also used in groups for quickly scaling awareness of new products, limited-time sales, etc. 

Digital Billboards 

Digital billboards are found in high-impact locations, like heavily traveled arteries and secondary intersections where traffic moves slowly. Digital OOH units come in varying sizes. Each unit’s ads rotate every 8 seconds, meaning multiple advertisers can share one highly desired location. Each advertiser receives approximately 1,250 spots per day.  At busy intersections, this can mean that vehicle occupants see 3-4 ads while waiting for a streetlight to change.  

Because ads are delivered to the unit electronically, the cost and lead time needed for vinyl creative is eliminated. New ads can be uploaded almost instantaneously and changed as often as desired. Dynamic ads magnify the memorability of these ads, utilizing concepts such as:

What is out of home advertising?

OOH advertising includes any advertising that reaches consumers when they are outside their homes, including billboards, transit ads, street furniture and place-based advertising. 

How is OOH advertising different from digital or online advertising?  

Out of Home ads exist in the physical world and can’t be avoided, while digital or online advertising targets people online and can often be blocked using ad blockers. Out of home is a “one message to many” format because it reaches a high number of people simultaneously. Digital or online ads are a one-to-one medium, because in most cases, one person is being served the ad on their phone, tablet, or computer.  

Is OOH advertising effective?

Multiple studies have shown that OOH increases awareness, brand recall, and purchase consideration. That effectiveness is even stronger when OOH is paired with digital media.

How much does billboard advertising cost?  

The price of a billboard depends on the size, the location, the traffic volume passing by the billboard, the duration for which the ad will run, and the format. Posters generally cost less than digital or bulletin boards. As a whole, the billboard industry has one of the lowest CPMs in all media.  

Who uses out of home advertising?

Brands from across all industries. Some of the top-spending industries include financial, legal, and healthcare services and quick serve restaurants.

How are audiences measured in OOH advertising?

Measurement services such as Geopath use location data, traffic counts, mobile data, and visibility metrics to calculate estimated impressions, reach and frequency.  

What are some guidelines for creating an effective out of home ad?

Bold visuals, minimal text, high contrast, and clear messaging are key. Viewers have just a few seconds to process the message, so simplicity is a necessity. 

How long should an OOH campaign run? 

Optimal results usually take around 12 weeks, and brand-building campaigns should run longer. A campaign with great reach and a very strong call to action can achieve success in 6-8 weeks.

Is OOH good for small businesses, or only large brands?

OOH can work for both. The hyper-local targeting of OOH can greatly benefit local and regional businesses, while national brands love OOH for its massive reach and scalability. 

How do brands measure OOH success?

Depending on the goal of the campaign, metrics may include impressions, lift in website traffic, lift in foot traffic, lift in brand awareness, or other KPIs.
