Getting noticed is the purpose of advertising and with outdoor billboards, this is possible to the widest number of people on a daily basis. The key is to not only be noticed, but remembered which can be accomplished by having your billboard in the right location.
Not all locations are equal
Everyone has seen billboards on the highways, but most do not remember what they are unless they pass by it on a regular basis.
The ones that are really remembered are in locations where there are regular or daily traffic jams. This is because the drivers have slowed down or are stopped and bored so they look around while waiting before they can continue on their way. Billboards in these areas get noticed.
Another place where outdoor billboards are more remembered are near intersections where traffic control lights are located. Because the vehicles are not moving, there is time for the drivers and passengers to gaze out the windows and observe their surroundings. Most traffic lights change every 30 seconds or so. That means instead of those passing by only having 3 to 6 seconds to see your sign, they have up to 30 seconds to see and remember your message.
Bends and Corners
When the road bends is a place where the driver is more aware of the road and the surrounding condition. They are no longer on autopilot as many would put it. There is a change in direction and each driver is at an elevated height of awareness. For many a billboard at or near a bend in the road is a landmark they will remember to be ready for that change.
Many intersections in America where two or more roads meet are a very popular location for outdoor billboards. There does not always have to be a stop light or sign for the advertising to be remembered. These billboards are very often used as landmarks in directions drivers give one another when helping someone get to their destination. This type of recognition occurs in both metropolitan and rural areas.
Billboards will be seen by both drivers of vehicles and pedestrians just walking around. With most of the population now glued to their smart phones, it only makes sense to target areas where there is a large concentration of mobile users. With an outdoor billboard located nearby a Wi-Fi hot spot, getting noticed is assured. Your billboard once again will be used as a landmark. By having your advertisement near several of them in a metro area, your brand will be recognized as a place to get connected.
The location of the outdoor billboard is very important, but so it the message you are trying to get the public to remember. Simple short messages are best so those seeing it can absorb the entire message at a glance. This will get your message remembered by more that glance at it.
