What is Lead Source Attribution?

Lead source attribution is the practice of tracking where each lead, meeting, and deal originated — which channel, campaign, or sequence first produced them — so you can see what's actually generating pipeline and revenue. Without it, you're spending blindly, unable to tell whether your results came from cold email, voice, SMS, or a specific message variant.

Good attribution ties a source to every lead at capture and carries it through to outcomes, letting you compare cost per meeting and win rate by channel. That turns budget decisions into evidence-based ones: double down on the sources producing qualified pipeline and cut the ones that don't.

Attribution depends on clean data flowing into your CRM, which is why it's tightly linked to CRM integration and consistent lead capture across channels.
