Per-conversion attribution settings (beta) for Google Ads customers

What it breaks

Two key events on the same property can now use different models; a report that sums them mixes models, and an Ads import from a re-linked property may carry a different default than last quarter.

Who it hits: Lead-gen accounts with several key events; anyone comparing month on month across the change.

The fix

List the model per key event, run last-click and data-driven side by side for 28 days, reset Smart Bidding targets from the new baseline.
