    WHAT FLOWS THROUGH BIGQUERY

    The signal BigQuery yields, and receives.

    Every kind of signal that moves between BigQuery and the platforms, through one hashed, deduplicated route.

    What flows Every platform Offline conversions Lead conversions Custom audiences Lead generation Signals hash · dedupe· route Google Meta Snap TikTok LinkedIn OpenAI
    Offline conversions
    Closed-won and point-of-sale tables leave BigQuery hashed and matched to the campaign that drove the sale.
    Lead conversions
    Lead-stage tables refresh on the scheduled query's cadence and arrive as conversion events, no export job.
    Custom audiences
    An LTV segment written once in SQL becomes a hashed, scheduled audience with no CSV on anyone's laptop.
    Lead generation inbound
    Renewal and subscription events post as they land, so recurring revenue reaches bidding the day it books.

    FAQ

    BigQuery questions, answered.

    Can we use our GA4 BigQuery export as a source?

    Yes, and it is the most common BigQuery pattern we deploy. The GA4 export lands in a dataset as daily and streaming tables, and Signals reads it with a scoped service account, so the web and app events you already collect in Analytics become server-side conversions on Meta, Google, and the other platforms without a second tag on the site.

    Does Datahash copy our warehouse?

    No. Reads are query-scoped and delivery is event-level, so nothing from your warehouse is copied or warehoused on our side. Identifiers are SHA-256 hashed before anything leaves BigQuery, and a self-hosted Core deployment is available when data cannot leave your own environment, in which case the hashing happens inside your perimeter.

    How fresh is the sync?

    On a schedule you set, from every 15 minutes to weekly, with incremental runs that read only the rows a query changed. The cadence follows whatever your scheduled query already keeps, so a table rebuilt nightly delivers nightly and one refreshed every few minutes delivers close to real time, without a full re-scan on each run.
