How do I send conversions to Meta, Google Ads, and LinkedIn?

Use Studio Head Tags for pixels and callback functions, then fire those functions from a Custom HTML (HTML Script) element when the visitor reaches a conversation step.

Setup

• In Studio go to Settings → Head Tags and paste the Meta Pixel, Google Ads gtag (including the gtag.js loader), and LinkedIn Insight Tag, plus functions such as report_conversion_interaction().
• On the node for that funnel step, add Custom HTML with an empty image that calls the function: <img src="" onerror="report_conversion_interaction()">. An empty src fails to load, so onerror runs the callback.
• Map interaction to Meta ViewContent / a Google conversion / a LinkedIn conversion ID; map lead capture to Meta Lead and the lead conversion actions. Performance Max and LinkedIn conversion ads should optimize on the lead action, with interaction as an earlier signal.
