    Asked on almost every call.

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

    The pace follows your ClickHouse tables: Signals sends changes from ClickHouse to Google Ads each time the read runs. Because it reads only the records changed since the last run, lead-value bidding fed by the stages your pipeline actually reaches stays current while analytics engineers on ClickHouse keep GCLID and hashed-email matching in view. Delivery needs no export and no manual upload.

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

    In ClickHouse, match rate tracks the email and phone quality your ClickHouse tables carry. Clean identifiers land for Google Ads; blank ones never will. The first Enhanced Conversions API report shows analytics engineers on ClickHouse where GCLID and hashed-email matching needs work, a data-quality task handled in ClickHouse.
