What is Facebook ad targeting interests?

Facebook Ad targeting interests is a feature that allows advertisers to reach people through the interests that they have shown on Facebook. These interests are then derived from the users’ activities, such as the pages they like, the content they interact with, and the pages they usually visit.
For instance, if you have an online shop that sells eco-friendly goods, you could target audiences with interests like “sustainable living”, “zero waste”, or “online shopping”.
In general, Facebook ad interest feature is the most ideal for:
- Those who are new to advertising can gradually build up their audience persona that best fits their preferred customers.
- Those who aim for niche markets can add more layers to their existing customer list and expand to broader audience segments.
How does Interest Targeting work on Facebook ads?
Like every advertising platform, Facebook ad targeting interests allows advertisers to select specific interests, behaviors, demographics, or categories that define the audience they want to reach. Let’s get down to the basics of this feature:

When setting up a campaign, you can select specific interests that align with your product or service. Here are some sample interests you can target:
- Hobbies
- Activities
- Entertainment
- Business & industry
- Food & drinks
- Sports & outdoor activities
- Shopping & Fashion
- Family & relationships
- Technology
Once interests are selected, Facebook utilizes its data to segment users who have indicated affinity or engagement with those chosen interests.
This targeting option can be further refined by combining it with other targeting parameters, such as demographics (age, gender, location), behaviors (purchase history, device usage), or custom audience lists.
Benefits of using Interest Targeting for Facebook Ad Campaigns
With the function of targeting audiences based on their preferences, Facebook ad targeting interests can give ad campaigns several benefits, such as:

How to choose the right interests for your Facebook ads?
Choosing the right interests is one of the most important steps in setting up a successful Facebook ad campaign. Here are key steps to help you find and select interests that actually match your audience and drive results.
1. Understand your product and audiences
What problem does your product solve, and who needs that solution? The answer will help you identify why they might respond to your ad in the first place.
For example, if you’re selling sportswear, your product appeals to people who usually play or watch sports. They might be fans of several athletes or clubs. Thus, instead of targeting only broad interests like “sports”, you should select interests like “major soccer league”.

2. Brainstorm related topics and brands
Besides your product, think about what else might interest your target audience, such as competitor brands, lifestyle choices, or tools they already use. This helps uncover targeting options that feel more natural to your audience.
For instance, if you’re selling desk organizers, your customers might also be interested in minimalism, Notion app, or home office setup. These are not directly about your product, but they signal the mindset and environment of someone who might buy from you.

3. Start with 3-5 interests for testing
When launching a campaign, don’t overload your ad sets with too many interests. Starting with 3-5 closely related options per ad set gives you cleaner performance data and makes it easier to optimize.
Let’s say you run a pet accessory store. you could test interests like “Dog lovers,” “Pet grooming,” and “PetSmart”. After a few days of running the ad, review performance and adjust based on which interests drive better results.

4. Mix broad and specific interests
Combining broad and specific interests in the same ad set helps Facebook balance reach and relevance. Broad interests give the algorithm more room to explore, while specific ones guide it toward the right type of user.
For instance, if you’re advertising wireless earbuds, you could pair a broad interest like “Consumer electronics” with a specific one like “Music streaming services”.
Common Errors in Setting Up Facebook Ad Interests
Several errors or issues can occur when setting up Facebook ad interests, leading to potential challenges in targeting the desired audience. Some common errors include:
1. Limited Targeting Options
Certain interests or targeting options might sometimes be unavailable due to restrictions or changes in Facebook’s ad policies. This limitation can restrict your ability to reach specific audience segments.
What to do:
Before setting up ads, remember to check for Facebook Advertising policies and jot down the restrictions concerning your creatives or targeting. If certain interests or targeting options are unavailable or restricted, try identifying alternative interests or related categories that align with your audience. Explore broader or similar interests that may serve as viable alternatives.
2. Audience Size Too Narrow or Broad
Choosing either too specific or too broad interests can affect your audience size. A narrow audience might limit your ad’s reach, while an overly broad audience might result in less relevant targeting.
What to do:
First, combine no more than 3 related interests and allow Facebook’s algorithms to work their magic with this focused interest blend. After that, monitor and optimize your detail targeting, you can add or remove if the received audiences don’t align with your target customers.
Remember to check for Facebook’s estimated audience size when setting up ad campaigns!

3. Interests Not Reflecting Audience Preferences
Sometimes, selected interests might not accurately represent your audience’s preferences. This mismatch can lead to low engagement rates or ineffective ad performance.
What to do:

6. Limited Audience Insights
Facebook might not always provide detailed insights into why certain interests perform better or worse, limiting your ability to fine-tune your targeting.
What to do:
Continuously monitor your ad performance metrics to evaluate the effectiveness of your interest targeting. Make adjustments based on the performance data, like engagement, impression, or conversion rate, to eliminate conflicts and improve targeting precision.
