The category

B2B attribution is broken in a specific way. The sales cycle runs 3–12 months, involves 8–12 stakeholders at the buying company, and spans channels that include events, SDR sequences, dark social, LinkedIn, paid search, and partner referrals. Last-click on a 6-month enterprise deal doesn't just produce the wrong answer — it produces a confidently wrong answer that actively misleads budget decisions. The CMO who cuts events because they show poor last-click attribution may be eliminating the channel that influences 60% of pipeline through touchpoints that leave no digital trace.

The right frame for B2B attribution is the account, not the person. A lead from Company X who attends a webinar, a different lead from Company X who clicks a LinkedIn ad three weeks later, and the VP of Company X who never clicked anything but signed the contract — these are all the same buying journey. Person-level MTA misses this entirely. Tools built for B2B attribution model at the account level and stitch individual touchpoints into account journeys.

The tensions in this category
MQL attribution vs account attribution

Most B2B marketing teams attribute at the lead level because that's what their CRM tracks. Deals close at the account level. The gap between these two frames is where most B2B attribution breaks.

Self-reported attribution vs algorithmic models

"How did you hear about us?" often outperforms algorithmic attribution in B2B because dark social, peer recommendations, and community channels are invisible to tracking. The best programs combine both.

Marketing-sourced vs marketing-influenced

This is a political fight in every B2B org. The same tools report different numbers depending on how "influence" is defined. Align on the definition before buying the platform.
