Linear Attribution
An attribution model distributing conversion credit equally across all customer journey touchpoints.
Frequently Asked Questions
What is a Linear Attribution Model?
A Linear Attribution Model is a multi-touch attribution model that distributes conversion credit equally across all customer journey touchpoints. This means that every interaction a customer has with a brand's marketing efforts, from the very first touch to the last, receives the same percentage of credit for the final conversion. For example, if a customer interacts with five different channels before purchasing, each channel is assigned 20% of the conversion value. This model is valued for its simplicity and for acknowledging that multiple channels contribute to a sale, but it does not account for the varying importance or influence of different touchpoints in the journey.
How is the Linear Attribution Model used in marketing analysis?
The Linear Attribution Model is primarily used to provide a balanced, high-level view of which marketing channels are involved in the customer journey. Marketers use it to ensure that top-of-funnel channels (like display ads or social media) are not completely overlooked in favor of bottom-of-funnel channels (like branded search), which often happens with last-touch models. It is particularly useful for businesses that value a consistent contribution from all marketing activities throughout the entire sales cycle. However, because it treats all touchpoints equally, it is often used as a baseline or a complementary model alongside more sophisticated methods like data-driven attribution or time-decay models to gain a more nuanced understanding of channel performance.
What is the difference between a Linear Attribution Model and a Position-Based Attribution Model?
The key difference lies in how conversion credit is distributed across the customer journey. The Linear Attribution Model assigns equal credit to every single touchpoint, regardless of its position. In contrast, the Position-Based Attribution Model, often called the U-Shaped model, assigns a higher percentage of credit to the first and last touchpoints, typically 40% each, with the remaining 20% distributed equally among the middle touchpoints. The Position-Based model is more sophisticated as it recognizes the importance of both the initial awareness-generating touchpoint and the final conversion-driving touchpoint, while the Linear model simply provides a flat, equal distribution across the entire path.
