Attribution

What is Attribution?

Attribution is the process of assigning credit for conversions to the marketing channels and touchpoints that influenced them. When someone buys from you, attribution answers: "Which marketing efforts made this happen?"

The challenge is that customers often interact with multiple channels before converting. They might see a Facebook ad, click a Google search result, read an email, and then convert. Who gets the credit?

Why Attribution Matters

Without attribution, you're guessing which marketing works. You might be pouring money into channels that aren't driving results, or underfunding ones that are.

Good attribution helps you:

• Allocate budget to effective channels
• Understand customer journeys
• Measure true marketing ROI
• Make data-driven decisions

Attribution Models

Different models give credit differently:

Last-Click Attribution

100% credit to the final touchpoint before conversion. Simple but ignores the journey.

First-Click Attribution

100% credit to the first touchpoint that introduced the customer. Values awareness over closing.

Linear Attribution

Equal credit to every touchpoint. Fair but perhaps over-simplifies.

Time Decay Attribution

More credit to touchpoints closer to conversion. Recognises the closing role of recent interactions.

Data-Driven Attribution

Uses machine learning to assign credit based on actual conversion patterns. The most accurate but needs significant data.

Attribution in GA4

GA4 defaults to data-driven attribution when you have enough conversion data. For smaller sites, it falls back to other models. You can view attribution reports in the Advertising section to compare how different models value your channels.

The Truth About Attribution

No attribution model is perfect. Cross-device tracking, privacy restrictions, and offline touchpoints all create blind spots. Use attribution as a guide, not gospel.
