When you think of billboard advertising, one of the first industries that probably comes to mind is legal services. From eye-catching taglines to larger-than-life lawyer portraits, attorney advertising has become a staple on highways across the country. But why are there so many lawyer billboards? Better question, do they actually work? 

We’ve launched billboard campaigns across just about every industry, and legal services stand out. Let’s explore the best practices that make legal billboard campaigns successful and how attorneys can make the most of their ad spend.

Why Are There So Many Lawyer Billboards?

The simple answer? They work.

Billboards offer unmatched local visibility for attorneys looking to generate leads in a specific city or region. Legal services often require a high level of trust, and repeated exposure through outdoor advertising helps potential clients become familiar with a lawyer’s name, face, and specialty. For personal injury attorneys, criminal defense lawyers, and accident claim specialists, name recognition can be the key to getting the call when someone’s in need.

Plus, many lawyers build billboard campaigns into their long-term marketing strategy, maintaining a consistent visual presence that reinforces brand credibility over time.

Do Lawyer Billboards Really Work?

Yes! But as with anything, they’re most effective when done right. It’s more than just slapping the name of your firm and phone number on a board. Billboard advertising works best for law firms that:

  • Operate in high-traffic areas
  • Offer services with immediate or urgent demand (e.g., car accidents, DUIs)
  • Want to build long-term brand recognition

Studies show that consumers are more likely to remember and contact a lawyer they’ve seen on a billboard, especially in emotionally charged situations like personal injury or wrongful termination. And with strategic placement and compelling design, these ads can significantly increase inbound calls and website visits.

However, success depends heavily on the clarity of the message, design quality, and location of the billboard.

Best Practices for Lawyer Billboard Advertising

Want your legal billboard to make an impact? Follow these tried-and-true tips and check out our in-depth blog post on how to create an effective ad for more.

1. Keep It Simple and Bold

Use large, legible fonts and a clear call to action. People often view billboards at 55+ mph, so stick to minimal text—ideally under seven words. Can you read it and absorb the most important information in just a few seconds? 

2. Use a Memorable Tagline

Whether it’s “Injured? Call Joe Now!” or “Your Freedom. Our Fight,” a catchy slogan sticks. Think emotional appeal with a legal punch.

3. Show Your Face

Lawyers who include a photo of themselves on their billboard build trust faster. It humanizes your firm and reinforces familiarity. Just ensure that it’s a professional headshot that communicates your credibility and reliability.

4. Include a Unique Selling Point

Do you offer free consultations? 24/7 availability? Multi-language support? Highlight what sets your firm apart. This will help you stand out in a sea of lawyer billboards.

5. Prioritize Location

Placing your billboard near hospitals, courthouses, or traffic accident hotspots can help you reach the right audience at the right time.
