Opportunistic advertising refers to the practice of taking advantage of unexpected or unplanned events, situations, or trends to promote a product or service. This type of advertising capitalizes on the current cultural, social, or economic climate to create relevant and timely marketing campaigns. It often involves using clever and creative tactics to reach a wider audience and generate buzz around a brand. However, it can also be seen as opportunistic and manipulative if not executed carefully and ethically. Overall, opportunistic advertising is a strategic approach that leverages the element of surprise to capture the attention of potential customers and drive sales.
