Attribution
Marketing attribution is the process of determining which marketing touchpoints, channels, or campaigns influenced a customer’s decision to convert, and assigning credit to them accordingly.
Attribution answers one of marketing’s most persistent questions: what actually caused this sale or lead? In a world where a single buyer might see a LinkedIn ad, read a blog post, open three emails, attend a webinar, and then request a demo, crediting only the last touchpoint tells an incomplete story. Attribution models are frameworks for distributing that credit more accurately across the whole journey.
The main attribution models are first-touch (all credit goes to the first interaction), last-touch (all credit goes to the final touchpoint before conversion), linear (credit is split equally across all touchpoints), time decay (more credit to touchpoints closer to the conversion), and position-based or U-shaped (heavier credit to the first and last touchpoints, with the rest split among the middle). Multi-touch attribution models aim to give a more complete picture but require more data and more sophisticated tooling to implement.
For B2B marketing teams, attribution is both a measurement challenge and a political one. Different models can make different channels look more or less effective, with real implications for budget allocation. No model is perfectly accurate; the goal is to choose one that is good enough to inform decisions and apply it consistently so you can track trends over time. Getting attribution right is also foundational to demonstrating marketing’s contribution to pipeline and revenue, which remains one of the most important conversations between marketing and the rest of the business.
What is the difference between first-touch and last-touch attribution?
First-touch attribution gives all the conversion credit to the very first interaction a prospect had with your brand, such as the ad they clicked or the blog post they first read. Last-touch attribution gives all the credit to the final interaction before conversion, such as the email that prompted them to request a demo. Both are simple to implement but both also tell a partial story, ignoring every touchpoint in between.
What is multi-touch attribution?
Multi-touch attribution distributes credit for a conversion across multiple touchpoints rather than assigning it to a single one. Different multi-touch models assign credit differently: linear attribution splits it equally, time-decay attribution gives more weight to recent touchpoints, and position-based attribution weights the first and last touchpoints more heavily. Multi-touch attribution gives a more complete picture of the buyer journey, but requires more data infrastructure to implement accurately.
Why is attribution so difficult in B2B marketing?
B2B attribution is difficult because buying decisions involve multiple people, long sales cycles, and many touchpoints across different channels and devices. A contact might engage with marketing content months before their organisation formally begins a buying process, and the person who converts may not be the same person who first engaged with your brand. Offline touchpoints, such as sales calls and events, are hard to track. And attribution data is inherently incomplete because you can only see the touchpoints that occurred within your own tracking systems.
