Guerrilla marketing involves unconventional and often low-cost marketing strategies that rely on creativity, imagination, and ingenuity to promote a product, service, or brand. In retail, guerrilla marketing tactics can include surprise or unconventional promotions, public stunts, or interactive experiences designed to create a memorable impact on consumers. These campaigns are typically unexpected and aim to generate buzz and word-of-mouth marketing. Guerrilla marketing is especially effective for smaller businesses with limited budgets, as it leverages unconventional methods to capture the attention and engage the target audience in unique and memorable ways.
