    FAQ

    Asked on almost every call.

    How often does the Google Sheets Meta Custom Audience sync run?

    You set the cadence, from near-real-time to a nightly Google Sheets sync of your Google Sheets rows into Meta. Since Signals processes only the newly dropped file, lookalike seeds and suppression lists that track your live customer base keeps pace and ops teams maintaining Google Sheets watch audience refresh cadence. One scoped connection sets it up, cadence adjustable later.

    What match rate should a Google Sheets-sourced Meta Custom Audience batch expect?

    In Google Sheets, match rate tracks the email and phone quality your Google Sheets rows carry. Clean identifiers land for Meta; blank ones never will. The first Custom Audiences API report shows ops teams maintaining Google Sheets where audience refresh cadence needs work, a data-quality task handled in Google Sheets.
