What is Behavior in Facebook Ads? (Unlock Targeting Secrets)

Introduction: How I Discovered the Power of Behavior Targeting on Facebook Ads

A few years ago, I was managing digital marketing for my eco-friendly product line. Despite investing heavily in Facebook ads, the results were underwhelming. My targeting strategy was basic — mostly demographics like age, gender, and broad interests such as “environmentalism” or “sustainable products.” Yet, sales barely moved.

One day, while researching advanced targeting options, I found behavior targeting — a feature allowing advertisers to reach users based on their real-world actions and digital habits. Skeptical but hopeful, I redesigned my campaigns to focus on behaviors such as “recent online buyers of eco-friendly products” and “users who frequently shop premium brands.”

Within weeks, engagement rates skyrocketed. My ads were no longer showing to just anyone interested in sustainability but to people who had already demonstrated buying behaviors aligned with my niche. The return on ad spend (ROAS) tripled in three months.

What Is Behavior Targeting in Facebook Ads?

Defining Behavior Targeting

Behavior targeting is an advanced Facebook advertising feature that allows you to target audiences based on their past actions rather than just demographics or interests. Unlike interests that indicate what users like or follow, behavior targeting focuses on what users actually do.

For example:

Have they recently purchased a product online?

Do they travel frequently?
What kind of devices do they use?
Are they gamers or media consumers?

Facebook collects this data from user activity inside and outside its platform to create behavior segments advertisers can target.

Why Behavior Targeting Is a Game Changer

Behavior targeting goes beyond assumptions. It’s rooted in data about real actions and purchase intent, allowing marketers to reach users more likely to convert.

Key data points:

According to Facebook’s internal research (2023), behavior-targeted campaigns see up to 70% higher engagement rates than interest-only campaigns.
WordStream’s 2024 analysis found that advertisers leveraging behavior data experienced a 50% lift in conversion rates on average.
Brands using behavior targeting reported up to 35% lower cost per acquisition (CPA) compared to broad targeting.

These numbers highlight why behavior targeting should be part of every serious advertiser’s toolkit.

How Facebook Collects Behavioral Data: A Deep Dive

On-Platform User Activity

Facebook tracks everything users do on its platforms — Facebook, Instagram, Messenger, WhatsApp — including:

Pages liked or followed

Videos watched (length and frequency)
Posts shared or commented on
Interactions with ads

Marketplace browsing activities

This rich dataset forms the backbone of behavior segments.

Off-Platform Data Collection

Facebook also uses tools like the Facebook Pixel installed on millions of websites and integrated SDKs in apps to track user actions outside its platforms:

Product views
Cart additions
Purchases

App installs and usage patterns

This allows Facebook to correlate online shopping and app behaviors with user profiles.

Third-Party Partner Data

Facebook partners with data aggregators who collect offline purchasing behaviors through loyalty programs, subscription services, public records, etc. This adds depth to behavioral profiles.

Device and Network Data

Information about device type (iPhone vs. Android), OS version, network type (Wi-Fi vs. cellular) is also tracked to segment users based on technology preferences.

Privacy Protections and Limitations

While Facebook collects extensive data, it anonymizes and aggregates user information before making it available for targeting. Advertisers only see segments without identifying individuals.

Facebook also adheres to privacy regulations like GDPR and CCPA by limiting certain data collection and giving users control over ad preferences.

Purchase Behavior

Purchase behaviors are some of the most powerful as they indicate clear intent or recent buying activity.

Recent Purchase Categories: Users who recently bought electronics, apparel, beauty products, etc.
Spending Habits: High spenders vs bargain hunters.

Online vs Offline Buyers: Those who shop primarily online vs in physical stores.
Device Purchase Types: Recent buyers of mobile devices or accessories.

Example: A brand selling premium headphones can target “recent electronics buyers” to capture users already in a tech-buying mindset.

Travel Behaviors

Travel-related behaviors are valuable for travel agencies, hotels, airlines, and related businesses.

Frequent travelers (based on flight bookings)
Airport visitors (tracked via mobile location data)

Commuters or daily travelers

Example: An airline might target “frequent travelers” who have visited airports multiple times in the past month.

Digital Activities

This includes user engagement with digital content and apps:

Video game players (casual vs hardcore)
App downloaders segmented by category (health, finance, education)
Media consumption habits such as frequent video watchers

Example: A mobile game developer can target “active video game players” who engage daily on gaming apps.

Device Usage

Target based on the technology users have:

Operating system (iOS or Android)

Device type (smartphone vs tablet)
Network connection (Wi-Fi vs cellular)

Example: An app optimized for iOS devices can exclude Android users by targeting only iOS device users.

Comparing Behavior Targeting with Other Facebook Targeting Options

Targeting Type	Definition	Advantages	Limitations
Demographic	Age, gender, education level	Easy to use; large audience reach	Low intent; broad
Interest	Based on user’s declared or inferred interests	Good for awareness; broad categories	Less precise; may have low conversion
Behavior	Based on user’s actions & purchase history	High intent; better conversion rates	Smaller audience; requires testing
Custom Audiences	Upload your own customer lists	Best for retargeting	Limited to existing customers
Lookalike Audiences	Users similar to your existing customers	Expands reach effectively	Requires quality source audience

Advanced Strategies for Maximizing Behavior Targeting Impact

Combine Behavior Targeting with Custom Audiences

Upload your customer email or phone lists into Facebook. Then use behavior targeting alongside to find new users similar in actions to your best customers.

Layer Behaviors with Interests and Demographics

Narrow down your audience by combining behaviors like “recent online buyers” with interests such as “fitness” for sports apparel campaigns.

Use Exclusion Lists Wisely

Exclude past purchasers or irrelevant segments so you avoid wasting budget showing ads to uninterested users.

Leverage Retargeting Funnels

Start by targeting broad behavioral segments at awareness stage then retarget engaged users with more specific offers.

Optimize Through A/B Testing

Run split tests comparing multiple behavior segments to identify which ones produce the highest ROAS or engagement.

Common Mistakes Marketers Make with Behavior Targeting

Over-segmentation: Creating too narrow behavior segments leads to tiny audiences that limit ad delivery.
Ignoring Combinations: Relying solely on one targeting type instead of layering behaviors with interests/demographics.
Neglecting Exclusions: Not excluding converted customers wastes budget.

Not Updating Audiences: Failing to refresh behavior selections as market conditions change.
Overlooking Testing: Not testing different behavior groups results in missed opportunities.
Assuming Behaviors Are Static: Behaviors evolve; retarget accordingly.
