Retargeting is a way to bring back people who already visited your website but didn’t buy. Instead of trying to convince brand‑new strangers, we show follow‑up ads to shoppers who viewed products, added items to their cart, or started checkout. Think of it like a smart reminder system — if someone looked at a product but left, they’ll start seeing relevant ads that highlight that exact product, offer social proof, or give them a reason to come back and complete their purchase. This helps recover lost sales, increase overall revenue, and make your ad budget work harder by focusing on people who already showed interest.
