An attribution model giving 40% credit each to first and last touchpoints, 20% to middle interactions.
Frequently Asked Questions
What is Position-Based Attribution (U-Shaped)?
Position-Based Attribution, also known as the U-Shaped model, is a multi-touch attribution model that assigns a fixed percentage of credit to the first and last touchpoints in a customer's journey, with the remaining credit distributed among the middle interactions. The most common distribution is 40% to the first touch (for awareness/acquisition), 40% to the last touch (for conversion), and the remaining 20% split evenly across all touchpoints in between. This model is a compromise between the simplicity of single-touch models and the complexity of full-path models, recognizing that both the initial introduction to the brand and the final push to purchase are the most critical steps in the conversion funnel. It is particularly useful for businesses that value both brand awareness and conversion optimization.
How can a marketer effectively use the Position-Based Attribution model?
Marketers can effectively use the Position-Based Attribution model to balance their budget allocation between top-of-funnel (TOFU) and bottom-of-funnel (BOFU) channels. By assigning 40% credit to the first touch, the model justifies investment in TOFU activities like content marketing, social media, and display ads that drive initial awareness. The 40% credit to the last touch validates BOFU channels like branded search and retargeting that close the sale. The remaining 20% provides insight into mid-funnel channels that nurture the lead. To implement it, a marketer should select this model in their analytics platform and use the resulting data to compare the ROAS of channels based on their role (acquisition vs. conversion) rather than just the final click. This helps in making more strategic, balanced investment decisions across the entire customer journey.
What is the difference between Position-Based Attribution and Linear Attribution?
The key difference between Position-Based Attribution and Linear Attribution lies in how they distribute credit across the customer journey. Linear Attribution assigns equal credit to every single touchpoint, regardless of its role in the funnel. For example, in a journey with five touchpoints, each would receive 20% credit. In contrast, Position-Based Attribution assigns disproportionate credit to the first and last touchpoints (typically 40% each), with only 20% distributed among the middle touches. This means Linear Attribution is best for long sales cycles where every interaction is considered equally important, while Position-Based Attribution is better for shorter cycles where the initial discovery and the final conversion are deemed the most influential moments.
