Google Ads adds a Connect a data source option for first-party tag integration
Natasha Kaurra has spotted a new "Connect a data source" option appearing inside Google Ads under Form Submission Conversion Goal, allowing advertisers to feed BigQuery or SQL-level data directly into the Google tag. Govind Singh has confirmed the same option appearing in his accounts.

What changed
The option marks a shift from offline conversion imports as the primary mechanism for deeper signal feeding, toward a more direct integration with structured warehouse data.
The practical implication for lead-gen advertisers is that Smart Bidding can now optimise against post-lead outcomes: booked appointments, qualifications, closed revenue: without the round-trip through CSV exports and offline conversion imports. Accounts feeding richer warehouse signals will train Smart Bidding more accurately than accounts still optimising on form-fill volume alone.
Why it matters for advertisers
For you, this means lead-gen accounts with a BigQuery or SQL-based source of truth on lead quality should plan a pilot integration before this becomes the standard expectation. The advertisers who build the warehouse-to-Google-tag path early are the ones who will have stable Smart Bidding signals through 2026, particularly as enhanced conversions and CAPI-equivalent integrations become routine.
