    CONNECTIONS / CouchDB / CouchDB to Google EC for Leads

    CouchDB documents into Google Ads, built for Google Enhanced Conversions for Leads.

    Signals reads your CouchDB documents through a read-only database user scoped to the CouchDB documents you name, then sends down-funnel lead milestones matched to the originating Google click so Google Ads sees lead conversions without an export.

    FAQ

    Asked on almost every call.

    How often does the CouchDB Google EC for Leads sync run?

    Delivery tracks CouchDB, run by application teams running CouchDB: a near-real-time or scheduled sync of your CouchDB documents feeds Google Ads on that cadence. Each run reads only the records changed since the last run, so lead-value signals matched to the paid click holds up on GCLID and hashed-email matching. The live debugger confirms every delivery inline.

    What match rate should a CouchDB-sourced Google EC for Leads batch expect?

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