You’ve seen them. Those long, messy strings of gibberish at the end of a URL when you click a product link on social media. Most people ignore them, but if you’re trying to make a dime on the internet, that tracking id on amazon is basically your digital fingerprint. It's the difference between getting a commission check and working for free.
Honestly, it’s a bit of a mess.
Amazon’s ecosystem is massive, and their attribution logic is—to put it mildly—finicky. People often confuse a "tracking ID" with a "store ID" or a "tag," and while they all live in the same neighborhood, they aren't the same house. If you’re an Associate or an Influencer, getting this wrong isn’t just a minor tech glitch. It’s a direct hit to your bank account. I’ve seen seasoned affiliates lose thousands of dollars in a single Q4 because they didn't realize their IDs weren't firing correctly on mobile redirects. It happens.
Why the Tracking ID on Amazon is Your Most Underused Asset
When you sign up for the Amazon Associates program, they give you a primary Store ID. It usually looks like yourname-20. But here’s the thing: using just one ID for everything is a rookie move.
A tracking id on amazon allows you to segment your traffic. If you’re running a tech blog, a YouTube channel, and a newsletter, you shouldn't be using the same ID for all of them. Why? Because you won’t know which one is actually making you money. You’re essentially flying blind. By creating unique IDs—maybe techblog-20, ytvideo-20, and emails-20—you can dive into the reporting console and see exactly where the conversions are happening.
Amazon lets you create up to 100 of these. Use them.
Think about the data. If you notice that your "kitchen-supplies-20" ID has a 12% conversion rate on TikTok but only 2% on Pinterest, that’s a massive signal. It tells you where to double down. Most people just throw links at the wall and hope they stick. Don't be that person. Use the granularity that the system provides.
The Anatomy of the Link
Let's get technical for a second, but not too much. A standard Amazon link looks like this: amazon.com/dp/ASIN/?tag=yourID-20. That tag parameter is where your tracking ID lives.
If that's missing, or if there's a typo, Amazon has no idea who sent the customer. They keep the profit. You get nothing. It sounds simple, but I’ve seen people copy-paste links from their browser bar after they’ve logged in, accidentally including their own session data instead of their affiliate tag. That is a one-way ticket to zero-commission land.
The Mobile App Problem (and Why It Kills Conversions)
Here is something nobody talks about enough: the "app-switch" fail.
You post a link on Instagram. A user clicks it. The Instagram in-app browser opens a mobile web version of Amazon. The user isn't logged in there. They see the product, realize they have to type their password, and they bail. Or, worse, they hop over to the actual Amazon app manually to buy it.
When they do that, the tracking id on amazon you provided in that original link often vanishes.
This is why "deep linking" tools exist. Services like Geniuslink or even basic URL builders help ensure that when a user clicks, it forces the Amazon app to open directly. If the app opens, the attribution usually sticks because the device ID is tied to the referral. Without deep linking, you are likely losing 30% to 50% of your potential earnings to the "friction" of the mobile web login.
It’s frustrating. It’s clunky. But it’s how the web works right now.
Understanding the 24-Hour Window
Amazon's cookie is notoriously short. You get 24 hours.
If someone clicks your link with your tracking id on amazon, you get a commission on anything they buy within the next 24 hours, provided they haven't clicked someone else's link in the meantime. If they add an item to their cart, that window extends to 90 days for that specific item.
But here is the nuance: if they click your link, look at a toaster, don't buy it, and then three days later go back to Amazon directly and buy that same toaster? You get zero. Zip. The tracking ID is dead at that point. This is why "urgency" and "intent" matter so much in content. You want them to click when they are ready to pull the trigger, not when they’re just window shopping.
Common Myths About Amazon Tracking
I hear a lot of nonsense in affiliate forums. Let's clear some of it up.
First, people think they can use their own tracking IDs to buy stuff and get a "discount" via commission. Don't do it. Amazon’s fraud detection is scary good. They track IP addresses, shipping addresses, and credit card names. If they catch you using your own tracking id on amazon for personal purchases, they will ban your account. They won't just take the commission back; they will close the account and keep your unpaid balance. It isn’t worth it.
Second, there's a myth that the ID "expires" if you don't use it.

The IDs don't expire, but your Associate account can be deactivated if you don't make at least three referred sales within the first 180 days. If your account gets closed, those IDs become "orphaned." The links still work—meaning the customer still goes to the product page—but the tracking ID is no longer associated with a live payout account.
Reporting Nuances
Amazon’s reporting dashboard is... old school. It’s not real-time.
If you’re checking your "Earnings Report" five minutes after your favorite influencer shouted you out, you’re going to be disappointed. It usually takes 24 hours for items to show up as "ordered," and they don't show up as "shipped" (which is when you actually get paid) until they leave the warehouse.
Sometimes you’ll see "Returned" or "Excluded" items. This usually happens if the product belongs to a category that doesn't pay commissions—like gift cards or certain grocery items in specific regions—or if the customer returned the item. It’s a gut punch, but it’s part of the game.
Strategic Implementation for 2026
The landscape is changing. With the death of third-party cookies in many browsers, the way a tracking id on amazon functions is becoming more reliant on first-party data and server-side tagging.
If you are a serious business owner, you should be looking at "Amazon Attribution" if you are a brand seller, or advanced sub-tagging if you are an affiliate.
- Audit your top 10 links. Go to your site right now. Click them. Look at the URL in the address bar. Does your tag actually show up? If not, your plugin might be broken.
- Create niche-specific IDs. Stop using one ID for your whole site. Create one for "Best Of" posts and one for "Individual Reviews." See which content type actually converts.
- Use the "Link Checker" tool. Inside the Amazon Associates Central, there is a literal "Link Checker." Paste your URL there. It will tell you if the link is valid and if the tracking id on amazon is properly assigned.
- Mind the "Friends and Family" Rule. If you send your link to your mom and she buys something, Amazon likely won't pay you. Their algorithm links your social graphs and common shipping locations. It feels like overreach, but they are aggressive about preventing "incentivized" traffic from close circles.
The reality is that Amazon's tracking system is a "black box" in many ways. We see what they want us to see. But by being meticulous with how you deploy your IDs, you move from guessing to knowing.
Final Steps for Optimization
The most successful people in this space treat their tracking IDs like a filing system.

Every time you launch a new campaign, generate a new ID. Label it clearly. When you check your reports at the end of the month, don't just look at the total "Shipped Revenue." Look at the "Conversion Rate" per ID.
If one ID has a 1% conversion and another has 8%, find out why. Is it the traffic source? Is it the way you’re framing the call to action? That data is the only way to scale without burning out.
Stop treating your tracking id on amazon as a static piece of code. It’s a diagnostic tool. Use it to find the leaks in your funnel, fix them, and ensure that every click you work so hard to get actually has a chance of putting money in your pocket. Check your links, verify your tags, and keep an eye on those mobile redirects. That’s where the money is won or lost.
