Assisted conversions: crediting the supporting cast

An assisted conversion is one where a channel participated in the path but was not the closing touch. The assisted-conversions view is a corrective to last-click: it reveals the supporting channels that last-click hides. It is a count of participation, not a clean measure of incremental contribution.

What this means

In a multi-touch path, the closing touch gets the last-click conversion and every other touch is an 'assist'. The assisted-conversions report counts how often each channel assisted. It exists to make the channels last-click ignores visible again.

How not to misread it

Assists are a participation count, not incremental lift. A channel can assist on thousands of paths that would have converted anyway. The classic error is to add assisted value to last-click value and double-count — the same conversion is not two conversions.

Read assists as a discovery tool that prompts deeper questions, especially about incrementality, not as a second budget to allocate.

How it appears in analytics and logs

A high assist count means a channel is often present but rarely closes. That can mean genuine nurturing — or a channel that simply appears a lot without changing outcomes.

Diagnostic use case

Use assisted conversions to find channels that quietly support journeys, while resisting the urge to add assist value on top of last-click value as if they were separate.

What WebmasterID can help detect

WebmasterID surfaces supporting touchpoints with confidence labels, so assist channels are visible without implying their participation equals incremental value.

Privacy and accuracy notes

Assist data comes from the ordered touchpoints of one site's own visitors; it does not need cross-site identity. WebmasterID keeps such paths first-party.
