Using Offline Events to Improve Facebook Custom Audience Targeting

Many businesses still focus heavily on online user activity for Facebook ad targeting, yet 80% of retail purchases in the U.S. still happen offline (Forrester Research). Ignoring offline behaviors means you're likely leaving a large portion of your customer journey untracked and unoptimized.

A bar chart showing that in 2022, 78 % of U.S. retail purchases were offline vs. 22 % online, with a projected change to approximately 72 % offline and 28 % online by 2028.

Offline retail still drives the lion’s share of U.S. purchases: in 2022, 78 % of sales occurred in‑store, while online made up 22 %—even as projections show offline remaining dominant (≈ 72 %) through 2028

Offline events encompass in-store purchases, phone orders, CRM data, and other customer interactions not tracked through traditional online means. By importing these into Facebook via tools like LeadEnforce, businesses can bridge the gap and greatly enhance ad relevance.

Performance Gains Through Offline Data

According to Facebook's internal studies, ad campaigns that include offline conversions see up to a 25% lift in ROAS compared to those that don't. By syncing offline event data, you ensure better alignment between your messaging and the real-world customer lifecycle.

Best Practices for Leveraging Offline Events

  1. Clean Your Data: Ensure offline data (names, emails, phone numbers) is formatted consistently and matches Facebook's hashing standards.

  2. Segment Intelligently: Separate repeat offline customers from one-time visitors to create higher-value Custom Audiences.

  3. Test and Compare: Run A/B tests between campaigns using only online behavior and those enriched with offline data.
