1

How Interest Targeting Works

Meta determines user interests based on pages they like, content they engage with, apps they use, ads they click, and self-reported profile information. You can target broad categories (fitness, technology, cooking) or specific interests (CrossFit, iPhone 15, vegan recipes).
2

Finding the Right Interests

Browse categories: Demographics, Interests, and Behaviours. Each has subcategories. Search for specific terms relevant to your product or service. Use the Audience Insights tool to research which interests your existing customers share.
3

Targeting Strategy

Layering: Combine interests to narrow your audience. 'Interested in fitness AND interested in nutrition' is narrower than either alone.

Exclusion: Exclude interests to remove irrelevant segments. If selling premium products, exclude 'discount shopping' interests.

Testing: Create separate ad sets for different interest groups to see which performs best. Once you find winners, scale those ad sets.

Interest Targeting vs Broad Targeting

As Meta's algorithm improves, broad targeting (minimal interest restrictions) often outperforms narrow interest targeting for conversion campaigns, especially with mature pixel data. Test both approaches.
