Interest Targeting
Interest targeting reaches people based on topics, pages, and activities Meta has associated with them, such as 'yoga' or 'small business owners'.
What it actually means
Interest targeting lets you narrow a core audience to people Meta believes care about specific topics, inferred from the pages they like, the content they engage with, and their behavior across the platform. It can feel powerful — you can stack interests to describe an ideal customer — but it has limits. Interests are probabilistic guesses, not certainties, and stacking too many can shrink the audience below a useful size. Meta's algorithm has also grown skilled at finding buyers on its own, so heavily layered interest targeting often underperforms a broad audience paired with strong creative. Interests remain useful for very niche offers and for keeping early-stage testing focused.
For a local business, interests work best as a light touch on top of location — for example, 'newlyweds' for a wedding venue — rather than a long, restrictive stack.
Related terms
A core audience is a targeting group built from Meta's own data — location, age, gender, interests, and behaviors — rather than from your customer lists.
An audience is the defined group of people your ads are eligible to reach, built from location, demographics, interests, behaviors, or your own data.
Broad targeting gives Meta minimal audience constraints — often just location, age, and gender — and relies on the algorithm to find buyers.
Geotargeting restricts your ads to people in specific locations — a country, city, ZIP code, or a radius around an address.
