How to Set Up Amazon Associates with Google Analytics

Introduction

Ever wondered how to combine the power of Amazon Associates with the insights of Google Analytics? Linking these two platforms lets you see exactly which links drive sales, how visitors behave, and where to double‑down on profitable content. In this guide, we walk you through the entire setup—step by step—so you can start tracking earnings like a pro.

Why Integrate Amazon Associates with Google Analytics?

• Data‑driven decisions: Identify top‑performing posts and keywords.
• Revenue tracking: Attribute sales to specific traffic sources.
• Optimization: Refine content strategy based on real user behavior.

Prerequisites

Before you begin, make sure you have:

1. An active Amazon Associates account.
2. A Google Analytics 4 (GA4) property or a Universal Analytics property (if still in use).
3. Access to edit your website’s HTML or a CMS plugin that allows custom scripts.

Step 1: Enable Amazon Associates Tracking ID

Amazon automatically adds a tag=yourtrackingID-20 parameter to every affiliate link. This is the core identifier you’ll use in Google Analytics.

How to find your tracking ID

Log in to the Amazon Associates dashboard > Account Settings > Tracking ID. Copy the ID (e.g., myblog-20).

Step 2: Add Google Analytics to Your Site

If you haven’t installed GA yet, follow these quick steps:

1. Log in to Google Analytics and create a new GA4 property.
2. Copy the gtag.js snippet provided.
3. Paste the snippet just before the closing </head> tag on every page.

For WordPress users, a plugin such as Site Kit by Google simplifies this process.

Step 3: Create a Custom Event for Amazon Clicks

We’ll use Google Tag Manager (GTM) to fire an event whenever a visitor clicks an Amazon link.

Set up GTM (if you don’t have it)

1. Create a GTM account and container for your domain.
2. Insert the GTM container snippet after the GA tag (or replace the GA tag if you prefer).

Build the click trigger

• Go to Triggers > New > Click – All Elements.
• Configure the trigger to fire on links that contain amazon.com and the tracking ID (e.g., myblog-20).

Set up the tag

• Select Tag Configuration > GA4 Event (or Universal Analytics Event).
• Enter an event name like amazon_associate_click.
• Add parameters:
  • link_url – {{Click URL}}
  • tracking_id – {{Click URL}} >> Extract the tracking ID using a URL variable.
• Choose the trigger you just created.

Publish the workspace.

Step 4: Verify the Event in Google Analytics

In GA4, navigate to Configure > Events. You should see amazon_associate_click after a few clicks. Use Realtime to test instantly.

Step 5: Connect Clicks to Revenue

Amazon only provides earnings data via the Associate’s reporting interface, not through an API. To approximate revenue:

1. Export the Earned Referrals report (CSV) weekly.
2. Match the tracking_id column with the tracking_id parameter captured in GA.
3. Import the merged data into Google Data Studio or Looker Studio for visual dashboards.

This workflow gives you a clear picture of which pages, traffic sources, and keywords generate the most Amazon commission.

Optional: Use UTM Parameters for Granular Tracking

If you want to differentiate campaigns, append UTM tags to your Amazon links, e.g.:

https://www.amazon.com/dp/B08XYZ?tag=myblog-20&utm_source=facebook&utm_medium=social&utm_campaign=summer_sale

Google Analytics will automatically capture these UTM values, allowing you to attribute sales to specific campaigns.

FAQ

Do I need Google Tag Manager?

No, you can attach an onclick handler directly in the HTML, but GTM keeps tracking code separate from the site and is easier to maintain.

Can I track Amazon purchases directly in GA?

Amazon does not expose conversion data via a pixel, so you must rely on the Associate’s reports and match them with click data.

Will this affect my site speed?

The GTM snippet is lightweight (<30 KB) and loads asynchronously, so any impact is negligible.

Is it legal to add tracking to Amazon links?

Yes, Amazon’s policies allow affiliate links to contain additional URL parameters, as long as the tracking ID remains intact.

Conclusion

By linking Amazon Associates with Google Analytics, you turn raw clicks into actionable revenue insights. Follow the steps above, test your events, and start optimizing content that truly converts. The data you gather will guide you toward higher commissions and smarter marketing decisions.
