Whether towering over the expressway or lining a city street, chances are you passed a billboard today. It might even be responsible for your afternoon pick-me-up or those weekend movie tickets. But have you ever stopped to think about what makes a billboard effective?

As a visual advertising medium, strong creative is the key to Out-of-Home (OOH) advertising success. But the average viewer has only about six seconds to take in your message. So how do you make sure you’re seen? Clear Channel Outdoor (CCO) can help. By following a few essential design principles, you can create and launch an impactful OOH campaign.

To understand what makes an OOH ad effective, you’ll need a basic understanding of a few key design concepts unique to the medium. 

Copywriting for Billboards

Perhaps the most important element of any OOH ad is the copy. With viewers often seeing your ads at highway speeds and from long distances, simplicity is key. When developing your headline copy:

  • Communicate a single, clear message to give consumers an instant “get.”
  • Stick to seven words or less for a quick, easy read in seconds.
  • Reinforce your brand personality with language and tone.
  • Include a call to action to engage your consumers.
  • Ditch phone numbers and lengthy URLs which are not easily recalled.

Follow these straightforward guidelines and you’re on your way to a compelling ad. Still feeling stuck? CCO’s creative team is ready to help you tailor a message that aligns with your unique goals.

Optimizing Visual Elements

With a powerful headline in hand, it’s time to tackle the visuals. As with copy, a few cardinal rules can help ensure your design performs its best:

  • Use the full height and width of the billboard to take maximum advantage of space.
  • Use large sans serif fonts that are easily legible at a distance.
  • Maximize contrast to ensure readability—think white text on vibrant backgrounds or dark text on light ones.
  • Ensure your logo and product imagery are prominently featured.
  • Play with scale and humor to create an unexpected juxtaposition.
  • Create silhouettes with bold colors and images that build intrigue.

Once you’ve created a standout visual to pair with your copy, you’re ready to adapt your ad across various types of OOH displays. CCO’s creative team can advise on file specs and production requirements—or take the lead in resizing your creative for seamless campaign execution.

Designing for Different OOH Display Types & Locations

Highway billboards might be the most familiar OOH format, but there are countless others. While the same core principles apply, each format has its own nuances. Keeping these in mind helps maximize the effectiveness of your creative.

For example:

  • Poster Panels, typically found on surface streets with slower traffic, allow for more detailed imagery and longer copy.
  • Transit shelters, viewed up close by pedestrians, can accommodate even more copy since dwell times are longer.

Likewise, location plays a huge role. Localizing and contextualizing your message is a great way to drive deeper engagement. CCO’s creative experts are here to help you adapt messaging or brainstorm new ways to make the most of your inventory.

Conditional Triggers & Technology

Even the best OOH creative can be taken to the next level with the right technology—especially in the digital out-of-home (DOOH) space. CCO offers a wide range of dynamic capabilities that can take your campaign up a notch. Creative can be seamlessly changed in real-time using conditional triggers allowing for updates based on time of day, weather conditions, traffic speeds, and much more. Engage consumers with social media integration. Create a buzz by displaying user-generated content across our digital networks, allowing for earned media through reshares and viral moments. If going really big is your goal, you can explore capabilities like 3D anamorphic, live-streaming, and augmented reality. If you can dream it, there’s a good chance we can bring it to life. Ask our creative teams about the many ways technology can enhance your DOOH campaign.

With these fundamental principles of OOH design in your toolkit, you’re well on your way to creating a memorable campaign. Remember: keep it simple, bold, and unforgettable! Ready to get started? Contact CCO today—we're here to help you turn your vision into reality.
