Many businesses have been incorporating stickers or decals into their guerrilla marketing campaigns. The "sticky" nature of stickers allows them to adhere to many surfaces, essentially turning any location your brand's sticker is stuck into an advertisement for you. Stickers also naturally viral. People just seem to love stickers and will collect them if you are giving them away. In addition to all this, custom stickers have a fairly low cost to manufacture, especially if they are being mass produced, which gives them an astounding ROI, compared to traditional marketing tactics. One sticker, stuck up in a public place, could receive potentially hundreds of impressions per day for however long it is stuck in place. The cost of that one sticker may have been mere cents.
Follow in the footsteps of these major brands and get creative with your next guerilla marketing campaign. You don't have to have a big budget to make a big impact, just some custom stickers or decals and a good idea.
