Guerrilla Marketing is the tactic of using unconventional advertising techniques. This often includes novelty approaches that increase brand awareness or improve engagement, such as innovative graffiti and street art leveraging the creativity of the marketing team.
This could be as simple as offering free samples to draw consumers in, or incredibly specific, such as in the case of the Deadpool movie billboards and online Guerrilla Marketing. This has become increasingly popular online, with social media offering more opportunities for effective Guerrilla Marketing.
