Qu'est-ce que Retargeting?
Définition Rapide
Le retargeting est une tactique publicitaire en ligne qui affiche des annonces aux utilisateurs ayant précédemment visité votre site ou interagi avec votre contenu.
Retargeting (also called remarketing) is a digital advertising technique that serves ads specifically to people who have already visited your website. When someone visits your site but doesn't convert, a small piece of code (a "pixel") places a cookie in their browser. This allows ad platforms to show your ads to that specific person as they browse other websites, social media, or search engines.
The logic behind retargeting is simple: someone who has already visited your site has demonstrated interest in your product or service. They're a much warmer audience than someone who's never heard of you. Retargeting keeps your brand in front of them and encourages them to return and complete their purchase or inquiry.
Retargeting can be segmented based on behavior. You can show different ads to people who visited your pricing page (they're close to buying) vs. people who only viewed a blog post (they're still learning). You can retarget cart abandoners with the specific products they left behind, or show testimonial-focused ads to people who viewed your services page.
Major retargeting platforms include Google Ads (Display Network and Search), Meta (Facebook and Instagram), LinkedIn, and programmatic platforms. Each offers different targeting options and creative formats, from display banners to video ads to native content.
Pourquoi c'est Important
Only about 2-3% of website visitors convert on their first visit. Retargeting gives you another chance to reach the other 97% who left without taking action. Because these people already know your brand, retargeting ads typically have 10x higher click-through rates and significantly lower cost-per-conversion than regular display ads.
Retargeting is one of the most cost-effective advertising strategies available because you're spending money on people who have already expressed interest, rather than trying to reach cold audiences.
