    WHAT THIS ENABLES

    WHAT FLOWS WHERE

    FAQ

    Asked on almost every call.

    How often does the GA4 Meta CTM sync run?

    The pace follows your GA4 events: Signals sends changes from GA4 to Meta as each event fires. Because it forwards each event as it arrives, conversation-led sales tied back to the click-to-message ad stays current while analytics teams instrumenting GA4 keep the ctwa_clid conversation match in view. Delivery needs no export and no manual upload.

    What match rate should a GA4-sourced Meta CTM batch expect?

    In GA4, match rate tracks the email and phone quality your GA4 events carry. Clean identifiers land for Meta; blank ones never will. The first Conversions API report shows analytics teams instrumenting GA4 where the ctwa_clid conversation match needs work, a data-quality task handled in GA4.
