Remarketing primarily focuses on targeting individuals who have previously interacted with your website or brand, making them more likely to convert on repeat visits. Display advertising to previous website visitors leverages cookies to show ads to those users as they browse other sites. This customization makes it more effective because it keeps your brand top-of-mind for users who have already shown interest in your products or services.

In contrast, the other options do not capitalize on prior user engagement in the same way. Sponsorships on local radio stations may raise brand awareness but do not target users who have already indicated interest. Cold emails to new customers aim at reaching an audience that has not previously interacted with your brand, making them less effective for remarketing. Similarly, billboard advertisements reach a broad audience without any prior engagement data, making them a general awareness tactic rather than a specific remarketing strategy. Therefore, display advertising to previous website visitors is indeed the most effective channel for remarketing efforts.
