Retargeting ads work by showing ads to people who already visited a website but left without doing anything. The reason they can be effective is that these people already showed some interest, so the ad is not coming from nowhere. What makes them work better is when the ad reminds the person of exactly what they looked at, maybe with a small discount or a reason to come back. Generic ads that just repeat the brand name rarely work. Do you think most businesses use retargeting ads in a way that actually feels relevant to the person seeing them?
