Revenue attribution connects closed revenue back to the marketing activity that influenced it, rather than stopping at leads or conversions. It is the hardest and most valuable form of attribution, because it answers whether marketing produced money rather than activity.

Lead attribution tells you what generated contacts. Revenue attribution tells you what generated money, and those are frequently different channels. A source producing cheap leads that never close looks excellent until you trace it to revenue. If you only measure to the lead, you will keep funding the channel that looks best and performs worst.

Example:

A channel producing the cheapest leads can rank last on revenue attribution, because those leads rarely close. Only tracing to closed revenue exposes that.

Why is revenue attribution better than lead attribution?

Leads are not money. A channel can produce cheap leads that never close, so tracing through to closed revenue reveals which marketing actually pays.

What makes revenue attribution difficult?

It requires connecting marketing data to closed deals across a long sales cycle, which demands clean data and a link between marketing systems and the CRM.
