Honestly, truckside advertising is a great OOH with many positive points. It helps grow businesses, it helps raise awareness, and it helps increase brand visibility. It's convenient, affordable and it's not rocket science. Yes, it can be creative as well, when you put your mind to it, or when you hire the right creative team behind it. But guerrilla marketing is a real standout, at least from a creative point of view. Before going any further, let me fill you in on what I'm talking about here.
Guerrilla marketing is an advertising strategy in which a company uses surprise and/or unconventional interactions in order to promote a product or service. The term was created in 1984 by writer Jay Conrad Levinson, and it was inspired by guerrilla warfare. Guerilla warfare is a form of irregular warfare that relates to strategies used by armed civilians such as ambushes, sabotage, raids, and elements of surprise. Guerrilla marketing uses similar tactics in the marketing industry. It can be labelled as a publicity stunt.
You can say that guerrilla and ambient are from the same family. Guerrilla can be found both outdoor or indoor, but it seems to have more impact outdoor. Also, guerrilla marketing is more aggressive than ambient. But since it's a form of OOH as effective as truckside advertising, let's compare the two.
