Offline conversions
Offline conversions are conversions that complete away from your website (a deal won in the CRM, a contract signed), imported back into the ad platform and joined to the original click by click ID or hashed email.

Offline conversions are conversions that complete away from your website (a deal marked won in the CRM, a contract signed, a subscription upgraded) and are imported back into the ad platform afterward, joined to the original ad click by its click ID (Google's GCLID) or by hashed email. They exist so lead-gen accounts can bid toward revenue instead of form fills.
#"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. What the import consumes decides whether it works: 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. That cadence matters because platforms book imported conversions against the click date, so a slow one keeps rewriting recent reports, and a missed capture is a conversion that never existed as far as bidding is concerned.
In practice: Buron's CRM feeds monitor exactly those two failure points (click-ID coverage and import recency) continuously.
The end-to-end setup, including the 2026 Data Manager migration and the two silent failure modes, is Offline conversion tracking: send CRM deals back to Google Ads; the Meta-flavored path is Meta offline conversions: the CRM upload path. The join key itself is defined at Click ID (gclid / fbclid / wbraid), and the territory routes from Conversion tracking & signal quality.

Enhanced conversions

Value-based bidding
Value-based bidding is automated bidding that optimizes toward conversion value instead of conversion count (tROAS and Maximize conversion value on Google Ads), and it's only as good as the values you feed it.
