What is remarketing?

• A. A strategy that blocks ads after a user visits a site.
• B. The process of using ads or follow-up emails to engage with potential customers who visited a website but didn't make a purchase.
• C. A method of collecting real-time data without user consent.
• D. A billing model for online ads.

Answer: (B)

Remarketing is about re-engaging people who have already visited your site but left without completing a purchase. It works by placing a tracking tag on your site to recognize those visitors as they browse elsewhere or by sending follow-up messages based on their behavior. This allows you to serve targeted ads or send follow-up emails to remind them of the products they viewed and encourage them to return to finish the purchase. The approach is more efficient because the audience has already shown interest, making conversions more likely than with completely new, or cold, visitors. The other options aren’t correct because blocking ads stops exposure, collecting data without consent raises privacy concerns, and a billing model refers to how ads are paid for rather than the tactic of re-engaging past visitors.
