TL;DR
First touch attribution credits the channel that introduced a customer to your store. Last touch credits the channel that drove the final purchase. Most Shopify stores need both models to understand which campaigns find new customers vs. which close sales.
What is Attribution Modeling?
Attribution modeling determines which marketing touchpoint gets credit for a conversion. When a customer sees multiple ads before buying, who gets the credit?
The two most common models are first touch and last touch attribution. Understanding when to use each can dramatically improve your marketing decisions.
What Is First Touch Attribution?
First touch attribution gives 100% of the conversion credit to the very first marketing interaction a customer has with your brand before purchasing.
Example:
A customer sees your Facebook ad → clicks a Google ad → buys from an email link.
First touch gives 100% credit to Facebook (the first touchpoint).
When to Use First Touch:
- Brand awareness campaigns - See which channels introduce new customers
- Top-of-funnel optimization - Understand customer acquisition sources
- Prospecting budget allocation - Know where new customers come from
What Is Last Touch Attribution?
Last touch attribution gives 100% of the conversion credit to the final marketing interaction before a customer makes a purchase.
Example:
A customer sees your Facebook ad → clicks a Google ad → buys from an email link.
Last touch gives 100% credit to Email (the final touchpoint).
When to Use Last Touch:
- Conversion optimization - See what closes the sale
- Retargeting analysis - Understand which retargeting works
- Short purchase cycles - When customers buy quickly
