    WHAT THIS ENABLES

    BigCommerce to Google Offline Conversions

    Google Offline Conversions for BigCommerce: Signals reconciles closed-won revenue to the Google Ads click through GCLID straight from your BigCommerce orders, hashed and consent-screened as orders complete.

    • Offline and in-store sales from your BigCommerce orders activated for Google Ads, as Signals reconciles closed-won revenue to the Google Ads click through GCLID.
    • Smart Bidding trained on booked revenue instead of a mid-funnel proxy, drawn from your BigCommerce orders by merchants running BigCommerce.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

    The conversion happens off Google, away from any pixel. Here is how BigCommerce closes the loop.

    WHO THIS IS FOR

    Built for the teams that own the number.

    Advertisers whose Google-sourced deals close days after the click, with the records already in BigCommerce orders, customers, and catalog.

    Merchants running BigCommerce activating Google Ads offline conversion import straight from BigCommerce orders.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Scoped API access to BigCommerce, reading only your BigCommerce orders to feed Google Ads' Offline Conversion Import (Google Ads API), sized for GCLID coverage.

    2. Map

      Signals reads your BigCommerce orders, and its columns map to Google Ads' Offline Conversion Import (Google Ads API) in the visual mapper, hashed and checked for GCLID coverage.

    3. Deliver

      On each run, Signals pulls your BigCommerce orders, reconciles closed-won revenue to the Google Ads click through GCLID, and sends only the orders that changed, with GCLID coverage in the debugger.

    WHAT YOU GET

    What changes when the CSV goes away.

    Capability Manual CSV upload Datahash
    Reporting Offline sales sit in a separate export, reconciled by hand. Revenue counted in the same OCI reporting as web conversions.
    Deduplication A re-uploaded file risks counting the same conversion twice. Deduped delivery, so a resent record never counts as a second conversion.
    Match visibility Match quality is a guess until the numbers look off. Match rate reported per upload, tied to the source event set that produced it.
    Effort and latency An analyst exports and uploads on a manual cadence. Server-side and automatic the moment BigCommerce records the event.

    FAQ

    Asked on almost every call.

    How often does the BigCommerce Google OCI sync run?

    The pace follows your BigCommerce orders: Signals sends changes from BigCommerce to Google Ads as orders complete. Because it sends only the orders that changed, Smart Bidding trained on booked revenue instead of a mid-funnel proxy stays current while merchants running BigCommerce keep GCLID coverage in view. Delivery needs no export and no manual upload.

    What match rate should a BigCommerce-sourced Google OCI batch expect?

    Coverage of hashed identifiers across your BigCommerce orders decides it, and merchants running BigCommerce own that inside BigCommerce. A live email or phone matches into Google Ads; neither, and it will not. First-run feedback flags GCLID coverage, which merchants running BigCommerce then raise inside your BigCommerce orders.
