    FAQ

    Asked on almost every call.

    How often does the Redshift TikTok Custom Audience sync run?

    The refresh schedule drives it: when the materialized view rebuilds nightly, TikTok gets a nightly feed, and an hourly refresh runs hourly. Each read touches only changed rows, so TikTok custom audiences mirroring the segment your data team publishes stays fresh for match quality on TikTok without RA3 load rising.

    What match rate should a Redshift-sourced TikTok Custom Audience batch expect?

    The fill rate of the view matters more than Redshift itself. A clean hashed email or phone matches; a blank one never will. The first scheduled read reports quality from TikTok's Custom Audience API, the figure TikTok advertisers seeding lookalikes and suppressing existing customers weigh against match quality on TikTok.
