Contextual targeting in X Ads (formerly Twitter Ads) refers to the practice of displaying ads based on the content or context of tweets, timelines, or topics that users are engaging with. Instead of relying solely on demographics or interests, contextual targeting ensures your ads appear in relevant conversations, trends, or keyword environments. For example, a fitness brand could target ads to users engaging with topics or hashtags like #HealthyLiving or #FitnessTips.
