6 Amazon Affiliate Link Mistakes That Cost YouTubers Money
Small Mistakes, Real Money
Amazon affiliate links are easy to add to a YouTube description — and just as easy to get wrong in ways that quietly cost you money. The worst part is that nothing warns you. A link can look perfectly normal while earning you nothing at all.
Here are the most common Amazon affiliate link mistakes YouTube creators make, why each one costs you, and how to avoid it.
1. Adding Links and Never Checking Them Again
The most expensive mistake is treating your links as "set and forget." Products go out of stock, listings get removed, and older models get replaced — and your link quietly breaks. Every viewer who clicks a dead link is a commission you will never earn, and you never find out it happened.
The fix is a habit, not a one-time thing: check the links in your top videos often, and look through your older videos every now and then. If you are not sure how often, here is a simple schedule to follow.
2. Leaving Your Affiliate Tag Off the Link
A link can open perfectly and still earn you nothing if your affiliate tag is missing. The tag is the part of the link that says the sale is yours — the "?tag=yourname-20" bit at the end — and it is what makes sure you get paid for it.
It goes missing when you copy a plain product link instead of one made with Amazon’s SiteStripe tool, or when a link shortener takes it out. Always make your links with SiteStripe, and check the tag is still there before you paste — a missing tag is one of the main reasons affiliate links quietly stop earning.
3. Linking to Products That Sell Out or Disappear
Recommending a great product only helps while people can actually buy it. When a listing shows "Currently unavailable", your link still opens — but it earns nothing, because there is no sale to make.
Tech and gadget products are the worst for this, since they sell out, get removed, and get replaced with newer models all the time. When you spot one that is unavailable, swap it for a similar product that is still in stock, so the clicks you send are not wasted.
4. Ignoring Your Older Videos
Older videos keep earning long after you publish them — search and the algorithm send viewers to them for years. But their links are also the most likely to have quietly died, simply because the products are older.
Do not only fix your newest uploads. Your older videos are often where the most broken links are hiding, and they are still bringing in clicks — here is more on why old videos quietly lose affiliate money.
5. Thinking Your Link "Expired"
Amazon affiliate links do not expire on their own — the link itself still works. What changes is the product behind it. So when a link stops working, it is almost never the link "expiring" — it is the product going out of stock, being removed, or being swapped for a newer model.
Knowing this saves you time: you do not need to rebuild links that were never the problem — you need to swap the products that changed.
6. Forgetting the Affiliate Disclosure
Both Amazon and advertising rules say you must tell viewers when a link earns you a commission. A single line in your description — such as "As an Amazon Associate I earn from qualifying purchases" — keeps you within Amazon’s rules and builds trust with your viewers.
Skipping it is one of the few mistakes here that can put your Amazon Associates account itself at risk, not just your commissions.
How to Catch These Before They Cost You
Almost all of these mistakes come down to one thing: there is no easy way to see, at a glance, which of your links are still working. A link checker solves that. AffiliScan is a free Chrome extension that scans your YouTube video descriptions, flags every Amazon link as working, broken, or unavailable, and checks whether your affiliate tag is still there — all in seconds. It can scan a whole channel in one go, so even your oldest videos take minutes to check instead of a weekend.
Frequently Asked Questions
What is the most common affiliate link mistake?
Not checking your links after you publish. Affiliate links break without any warning — a product goes out of stock or gets removed and the link quietly stops working — so links you never check slowly turn into lost commissions.
How do I know if my affiliate tag is missing?
Look for the "?tag=yourname-20" part at the end of your Amazon link. If it is not there, the sale will not be credited to you. A link checker can flag tag-stripped links for you automatically.
Do broken affiliate links hurt my Amazon account?
Broken links mostly cost you commissions, not your account. The bigger risk to your account is breaking Amazon’s rules — like skipping the affiliate disclosure they require — so fix those first.
How often should I check for these mistakes?
A good baseline is to check the links in your top-earning videos every week, scan your whole channel about once a month, and check every new video right after you publish it.
Final Thoughts
None of these mistakes are hard to fix — the hard part is spotting them, because affiliate links break quietly. Build every link with SiteStripe, add your disclosure, and check your links on a regular schedule.
Do that, and you keep the commissions you already worked hard to earn — instead of sending your viewers to dead products and your income to zero.
