Offline conversions

Offline conversions complete away from your website and are imported back into the ad platform afterward, joined to the original ad click by click ID or hashed email.

A deal marked won in the CRM, a contract signed, a subscription upgraded: all imported into Google Ads or Meta after the fact, so lead-gen accounts can bid toward revenue instead of form fills. The join needs three things: a click ID captured at the first form fill and stored verbatim in the CRM, a conversion value from the closed deal, and a regular upload cadence.

#"Offline" means later in the funnel, not in a store

In B2B vocabulary, offline conversions are CRM outcomes matched back to clicks; nothing happened in a physical location. (Retail's in-store transactions matched through POS and loyalty data are a different mechanism with different plumbing.) Cadence matters because platforms book imported conversions against the click date: a slow upload keeps rewriting recent reports, and a missed click-ID capture is a conversion that bidding never sees.

In practice: Buron's attribution coverage measures click-ID capture (the share of leads arriving with one stored), the first point where this quietly fails.

The end-to-end setup, including the 2026 Data Manager migration: Offline conversion tracking: send CRM deals back to Google Ads. The Meta path: Meta offline conversions: the CRM upload path.
