Retargeting

Retargeting (also called remarketing) is a form of online advertising that displays ads to people who have already visited your website or interacted with your brand. Technically it works via cookies or pixels (e.g., Facebook Pixel, Google Tag). Use cases: Bring back cart abandoners, move product viewers to purchase, convert blog readers to leads, turn existing customers into repeat buyers. Platforms: Google Display Network, Meta Ads, LinkedIn, Criteo. Best practices: Frequency capping (don't annoy), segmented audiences, different creatives per funnel phase, burn pixel after conversion.
