Why Offline Data Matters in Facebook Ad Targeting
With third-party cookies on the decline and increasing emphasis on first-party data, advertisers need alternative methods to find relevant users. One of the most underutilized yet powerful sources is offline data — such as CRM databases, POS records, email subscriber lists, and customer support logs.
What Are Lookalike Audiences?
Lookalike Audiences are groups of Facebook users who share similar characteristics and behaviors with your existing customers. When created from high-quality offline data, these audiences become even more valuable — reflecting real-world purchasing behavior rather than just online activity.
According to Meta, advertisers using Lookalike Audiences achieve up to 56% lower cost per acquisition (CPA) compared to broad targeting.
How to Use Offline Data for Lookalike Targeting on Facebook
1. Collect and Clean Your Offline Data
Start with a high-quality seed list from your CRM, sales system, or email database. Include relevant customer attributes like:
-
Phone number
-
Email address
-
First and last name
-
Location (city, ZIP, state)

2. Upload via LeadEnforce

3. Create Lookalike Audiences
Once your Custom Audience is created from the offline data, use Facebook Ads Manager or LeadEnforce to generate a Lookalike Audience. You can define the audience size (1% to 10% of the population) based on how broad or narrow you want the match to be.
4. Layer with Behavioral Targeting
Enhance your Lookalike strategy by layering it with interest-based targeting or demographic filters. For example:
-
Interests: small business marketing, CRM tools
-
Demographics: age, gender, household income
-
Behaviors: recent purchasers, engaged shoppers
