Billboards are huge landmarks on the road that people notice, remember, and TALK about.
Using eyecatching colors and copy can make your Billboard memorable, burning your company name and image into the minds of your audience. Many boards on highways reach hundreds of thousands of people every day. That's a lot of different people seeing your ad every day. Most advertisers want the audience to remember the name of their company and what the company does as most important. What generates recall more than anything is the number of times someone sees an ad.
