What is Attribution
Also known as: marketing attribution, attribution model, attribution modeling, conversion attribution
Attribution build-up
One sale, several touchpoints. Attribution decides how much credit each step on the path receives.
Definition
The process of identifying which marketing touchpoints or campaigns get credit for driving a customer conversion. It assigns credit to each touchpoint on the customer's path to purchase.
A method of evaluating the marketing touchpoints a customer encounters on their path to purchase, assigning credit or value to each interaction to analyze campaign performance.
Why it matters
Attribution helps businesses understand the true impact of their marketing channels along the customer journey. By using the right attribution model, you can avoid over-crediting a single channel (like search ads) and better allocate budget to channels that build initial awareness (like content marketing).

Improvement tips
- Choose an attribution model that matches your business model, such as multi-touch or linear for long sales cycles.
- Use UTM parameters consistently across all campaigns to ensure accurate tracking data.
- Evaluate channels using incrementality testing to measure if ads are driving new sales or just capturing existing demand.
Common mistakes
- Relying entirely on first-click or last-click attribution, which oversimplifies the multi-touch customer journey.
- Ignoring dark social or word-of-mouth touchpoints that analytics software cannot track.
- Assuming attribution data is perfectly accurate despite privacy changes and cross-device tracking limitations.
