How to Set Up Amazon Attribution (Track Off-Amazon Traffic)

What is Amazon Attribution?

Amazon Attribution is a measurement tool that lets you track how your off-Amazon marketing efforts drive sales on Amazon. It works by generating tagged URLs (similar to UTM parameters in Google Analytics) that you use in your external campaigns. When a shopper clicks a tagged link and eventually purchases on Amazon, that sale is attributed to the specific campaign, channel, and creative that drove the traffic.

Before Attribution, sellers driving external traffic to Amazon were flying blind. You could send thousands of visitors from Instagram to your listing, but there was no way to know how many of those visitors actually purchased. You were spending money on external advertising without any way to measure ROI. Attribution solves this by closing the loop between off-Amazon marketing spend and Amazon sales.

Why external traffic tracking matters

Amazon rewards sellers who drive external traffic. Products that receive traffic from outside Amazon tend to rank better organically because external traffic signals to Amazon's algorithm that your product has demand beyond the Amazon ecosystem. This creates a virtuous cycle: external traffic improves organic ranking, which drives more Amazon traffic, which drives more sales.

Without tracking, you can't make intelligent decisions about your external marketing spend. Should you invest more in Instagram ads or Google Ads? Is your email newsletter driving actual purchases, or are subscribers just browsing? Which product should you feature in your TikTok content? Attribution data answers these questions with real purchase data, not guesses.

The stakes are higher than most sellers realize. If you're spending $2,000/month on Instagram ads driving traffic to Amazon, and only 30% of that spend is driving profitable sales, you could reallocate $1,400/month to the channels and products that actually convert. Over a year, that's $16,800 in smarter spend.

How to set it up

Setting up Attribution takes about 15-20 minutes. Here's the process:

1. Access Attribution. In Seller Central, go to Advertising, then Amazon Attribution. If you don't see it, confirm your Brand Registry enrollment is active.
2. Create a campaign. Name it after your traffic source (e.g., "Instagram_Spring2026"). Choose "Manually create tags" for maximum control.
3. Add products. Select the ASINs you want to track for this campaign. You can add multiple products per campaign.
4. Create ad groups. Each ad group represents a specific creative, ad set, or content piece. Name them descriptively: "IG_Feed_CuttingBoard_Lifestyle" or "Email_April_Newsletter."
5. Generate tagged URLs. Attribution generates a unique URL for each ad group. This URL looks like a normal Amazon product URL with tracking parameters appended.
6. Deploy the URLs. Use these tagged URLs in your Instagram ads, email links, Google Ads destination URLs, TikTok bio links, blog posts, or anywhere else you link to Amazon.

Important: use separate tags for each channel and campaign. "Instagram_April_CuttingBoard" and "Email_April_CuttingBoard" should be different tags so you can compare channel performance.

The Brand Referral Bonus

This is one of the most underutilized programs on Amazon. The Brand Referral Bonus gives you approximately 10% back on sales attributed to your external traffic. In practice, this reduces your referral fee from the standard 15% to approximately 5% on those sales.

The bonus is calculated as an average of 10% of the product sale price. It's credited to your seller account and appears as a line item in your settlement reports. The credit applies to all sales from shoppers who clicked your Attribution link within the 14-day attribution window, even if they purchase a different product from your brand.

The math is compelling. If you drive $10,000/month in Amazon sales through external traffic with proper Attribution tags, the Brand Referral Bonus returns approximately $1,000/month. That's $12,000/year in effectively reduced fees. For many sellers, this bonus alone covers the cost of their external advertising.

To qualify, you simply need to use Attribution tags on your external links. The bonus is automatic once Amazon can attribute the sale to your external traffic. There's no additional enrollment required beyond having Brand Registry and creating Attribution campaigns.

Which channels to track

Any channel that sends traffic to your Amazon listings should have Attribution tags. Here are the most common channels and what to expect:

Social media ads (Instagram, Facebook, TikTok): The most common use case. Create tags for each ad set so you can compare creative performance. Social ads typically convert at 3-8% on Amazon (lower than on-Amazon PPC because the traffic is colder).

Google Ads: Shoppers searching on Google often end up buying on Amazon. Running Google Ads with Attribution-tagged Amazon URLs captures this behavior and lets you measure the ROI. Some sellers find Google Ads drive Amazon sales at a lower cost than Amazon PPC for certain keywords.

Email marketing: If you have a customer email list, every product link in your newsletters should be an Attribution-tagged URL. Email traffic tends to convert well (10-15%) because these are existing customers who already trust your brand.

Influencer partnerships: Give each influencer a unique Attribution tag. This lets you measure exactly how many sales each influencer drives, turning "brand awareness" into a measurable ROI calculation.

Blog and content marketing: If you write blog posts or have a brand website that links to Amazon products, tag those links. This tracks how your content marketing investment translates to Amazon sales.

Analyzing your results

The Attribution dashboard shows a funnel for each campaign: clicks, detail page views, add to cart, purchases, and total sales. The key metrics to focus on:

Click-to-purchase rate: What percentage of external clicks result in a purchase? Benchmark: 3-8% for social ads, 5-12% for email, 2-5% for Google Ads. If your rate is below these ranges, your listing may not be converting the traffic well.

Cost per acquisition (CPA): Divide your external ad spend by Attribution-tracked purchases. Compare this to your Amazon PPC CPA. If external traffic CPA is lower, you should shift more budget to external channels.

Brand Referral Bonus earned: Track the monthly bonus to ensure you're capturing the full value. If your bonus seems low relative to external traffic volume, check that all links are properly tagged.

Channel comparison: Which external channel drives the most sales per dollar spent? This should inform your marketing budget allocation. Most sellers discover that 1-2 channels dramatically outperform the others.
