Interest Targeting in Facebook Ads Interest targeting is one of the most powerful features inside Facebook Ads Manager. With billions of active users across Meta platforms, you don’t want to show your ads to everyone—you want to reach people who are most likely to care about your product or service. So what is it? Interest targeting allows you to reach users based on what they like, follow, or engage with. Meta collects data from pages users follow, ads they click, apps they use, and even purchase behaviors. If someone often interacts with fitness content, Facebook will categorize them under “Health & Fitness.” If you’re selling yoga mats, targeting “Yoga,” “Meditation,” or “Fitness Enthusiasts” ensures your ad is more relevant. Why does this matter? ✔️ Better engagement (higher CTRs). ✔️ Lower costs (improved relevance). ✔️ Stronger conversions (ads reach people already interested in your niche). Best practices: Start broad, then narrow down once you gather data. Layer interests with demographics like age, gender, or income. Exclude audiences who are unlikely to convert (e.g., “discount shoppers” if you sell premium products). Test one interest at a time to identify winners before stacking multiple. Refresh your interests regularly—audiences evolve. Examples: Fitness brand: target “Yoga,” “Pilates,” “Healthy Living.” Luxury watch store: target “Rolex,” “Luxury Lifestyle,” “Business Executives.” Online course: target “Digital Marketing,” “SEO,” “HubSpot.” Pro tip: Don’t rely only on interests. Combine them with Custom Audiences (past buyers, website visitors) and Lookalike Audiences for scaling. Interests are great for testing cold traffic, but your best long-term results come from building audiences around your own data. In short, interest targeting is not “set and forget.” Test, analyze, optimize, and repeat. The more precisely you understand your audience’s passions, the more profitable your campaigns will be.
