Offline Conversions
Also known as: Offline Events, Offline Conversion Upload
Offline conversions are sales that happen away from your website — calls, store visits, signed contracts — uploaded back to ad platforms for credit.
What it actually means
Most local revenue closes offline: on a phone call, at the counter, in a driveway estimate. Ad platforms can't see any of it unless you tell them. Offline conversion uploads send those real-world outcomes — matched by email, phone number, or click ID — back to Meta or Google, where they connect to the original ad click. The payoff is double: your reporting finally reflects actual revenue instead of just form fills, and the optimization algorithm starts hunting for people who become paying customers rather than people who merely submit forms. Accounts that feed offline data back consistently outperform those optimizing on shallow signals.
Uploading your closed jobs each week teaches Meta the difference between a lead who booked a $4,000 remodel and one who ghosted — and it will find you more of the former.
