Why Your Affiliate Links Stop Working (And How to Fix It)

You wrote a great post six months ago. It's still getting traffic, readers are still clicking your affiliate links — but you're not earning a penny from it.

Welcome to one of the most frustrating parts of affiliate marketing: links that quietly stop working. No error message, no email, just lost revenue you never notice.

The good news? Once you understand why links die, you can build a workflow that keeps them earning for years. Let's walk through it.

The 5 most common reasons affiliate links break

Affiliate links aren't simple URLs. They're tracked, branded, and tied to programs that change all the time. Here's what typically goes wrong:

• The product gets discontinued. The retailer removes the page, and your link now leads to a 404 or a generic category page (which earns you nothing).
• The affiliate program shuts down. Brands switch networks, pause programs, or move everything in-house. Your old tracking ID becomes worthless overnight.
• Your account gets dropped. Some programs drop affiliates who haven't made a sale in X months. You keep using the link; the commission just vanishes.
• The URL structure changes. A brand rebuilds their site, the deeplink format changes, and your carefully crafted product link leads nowhere useful.
• Cookie windows or terms shift. The link technically works, but the program cut commission rates, shortened tracking windows, or excluded certain product categories.

The nasty part is that most of these failures are silent. Your link looks fine. Readers click. Nothing breaks visibly — except your paycheck.

A quick example: the cookware post that stopped earning

A food blogger I know wrote a popular roundup of non-stick pans. It ranked well and drove about 200 clicks a month to a major retailer.

Nine months in, her earnings from that post dropped to zero. She assumed traffic had tanked. It hadn't.

What happened: the retailer had migrated to a new affiliate network. Her old links still worked — they just weren't attributed to her anymore. One afternoon of updating links restored her commissions. But she'd lost roughly $400 in the meantime.

This is painfully common. And the fix is a system, not a one-off cleanup.

How to future-proof your affiliate links

You can't stop brands from changing things. But you can make those changes painless to handle.

1. Use a link management layer

Instead of pasting raw affiliate URLs into your posts, route them through a short link you control (for example, yourblog.com/go/product-name). When the underlying affiliate link breaks, you update it in one place — not in fifty old blog posts.

This is the single biggest quality-of-life upgrade in affiliate marketing. It turns a weekend of cleanup into a 30-second fix.

2. Track link clicks, not just earnings

If you only look at your affiliate dashboard, broken links are invisible. But if you track clicks on your own short links, you'll instantly spot the red flag: clicks going up, commissions going down.

Tools like Squirrel are built exactly for this — they turn the links you're already sharing into trackable, swappable, monetised links so you see the whole picture.

3. Audit your top 10 posts every quarter

You don't need to check every link every month. Just focus on the pages that actually drive revenue or traffic.

• Open each post and click every affiliate link.
• Confirm it lands on a real product page — not a 404, homepage, or "out of stock" message.
• Check your affiliate dashboard to confirm the click registered.

4. Diversify your programs

If one retailer represents 80% of your affiliate income, one policy change can wipe out most of your earnings. Aim for at least 2–3 programs per product category so you always have a backup link to swap in.

5. Keep a simple link inventory

A basic spreadsheet works: post URL, affiliate program, product, date added, last checked. It sounds tedious — but when a program shuts down, you'll know exactly which posts need updating in minutes.

What to do the moment you spot a broken link

When (not if) you find a dead affiliate link, here's the fastest path back to earning:

1. Find a replacement product from the same retailer, or jump to a competing program you already use.
2. Update your short link to point to the new destination. Every old post now works again instantly.
3. Add a note to your content calendar to review surrounding text — if the old product had specific details (price, color, model), update those too.
4. Log the change in your spreadsheet so you can spot patterns (some programs break more than others).

The mindset shift that makes this easy

Most beginners treat affiliate links as "set and forget." They're not. Think of your links as a small garden — they need occasional weeding, not constant labour.

Spend 30 minutes a quarter on link maintenance, use a short-link layer from day one, and your affiliate income becomes something that compounds instead of quietly leaking away.

Your six-month-old posts should be earning more over time as they rank higher — not silently drying up. With a simple system in place, they will.
