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. The attribution tool you choose determines which models you can actually see.
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

How to Choose the Right Attribution Tool for Shopify
Not every attribution tool gives you the same view. Some only offer last-touch reporting, which means you never see which campaigns introduced customers in the first place. Others require complex setup, custom scripts, or a Shopify Plus plan before you can start tracking. When evaluating an attribution tool for your store, prioritize three things: support for multiple attribution models, native Shopify integration, and ease of setup.
Native Shopify integration matters more than most merchants realize. Tools that rely on third-party script tags are vulnerable to ad blockers, browser privacy restrictions, and theme conflicts. Shopify's Web Pixel Extension API loads tracking within Shopify's own infrastructure, bypassing these issues entirely. An attribution tool built on Web Pixels captures more sessions and produces more accurate data than one that injects external JavaScript into your storefront.
BlackBox is built specifically for this use case. It installs in two minutes from the Shopify App Store, deploys a Web Pixel automatically with no code or theme edits, and gives you first-touch, last-touch, and linear attribution side by side from day one. You don't need Shopify Plus, a developer, or a separate analytics platform. For a broader comparison of what's available, see our guide to the best Shopify attribution tools.
The right attribution tool doesn't just show you numbers — it shows you how your channels actually work together so you can make confident budget decisions instead of guessing.
Should Shopify Stores Use First Touch, Last Touch, or Both?
Most Shopify stores should use both attribution models side by side — first touch reveals where customers come from, last touch reveals what converts them.
BlackBox gives you both attribution models side-by-side, so you can see the complete picture of your marketing performance. For a deeper look at models that split credit across multiple touchpoints, read our guide to multi-touch attribution for Shopify.
Pro Tip: Compare first touch and last touch data. If they're very different, you have a multi-touch customer journey. If they're similar, customers are converting quickly from a single source.
