How do I send conversions to Google Ads and Performance Max?

If the company is invoiced, connect Google Ads in Console → Settings → Integrations. SMOC creates the click-conversion actions and uploads interaction, lead, and Smart Click. Set the asset-group Final URL to the Flow URL only, and paste the URL parameters as the Final URL suffix ({campaignid} in both utm_campaign and utm_id). Performance Max should treat Lead as primary and interaction as a secondary signal. If you have not connected, create conversion actions in Google Ads, paste gtag in Head Tags, and call them from Custom HTML.
