Picture this: you've spent six months building out a niche blog. You've written 40 posts, embedded affiliate links throughout, and finally started seeing some consistent commission income. Then, out of nowhere, your earnings quietly drop. Not dramatically — just enough to make you uneasy. You refresh your affiliate dashboard, check your traffic stats, scratch your head. Everything looks the same. What changed?
Nine times out of ten, the answer is broken affiliate links.
It's one of the most common and least talked-about problems in affiliate marketing. And because it's invisible — your blog looks completely fine to you — it can silently drain your income for months before you even realize something's wrong.
What "Broken Affiliate Links" Actually Means
A broken affiliate link is any link on your blog that no longer reaches its intended destination and gets your commission credited in the process.
This can happen in a handful of ways:
The merchant changes their URL structure. You linked to example.com/product/blue-widget, and they redesigned their site. Now that URL returns a 404. Your link still exists on your page, but clicking it goes nowhere.
The merchant leaves the affiliate program. You signed up through ShareASale or Impact to promote a brand. They quietly exit the program. Your tracking link now redirects to a generic page — or breaks entirely — and even if someone buys, you don't get credit.
The product gets discontinued. That specific product you reviewed and linked to? It's been pulled from their catalog. The URL is dead. Readers hit a dead end.
The affiliate network changes their tracking URL format. Less common, but it happens — especially if a merchant switches networks. Your old link structure is simply no longer valid.
None of these are your fault. But they're all your problem.
Why Most Bloggers Never Notice
Here's the cruel part: broken affiliate links don't trigger any kind of alarm. Your site doesn't go down. Your traffic doesn't drop. Google Analytics shows the same sessions and pageviews. Everything looks healthy in your WordPress dashboard.
The only signal you get is a quieter affiliate dashboard — and even then, it's easy to chalk up to seasonal trends or algorithm fluctuations.
If you're running a site with more than 50 posts, it's genuinely difficult to know whether your links are working without going through each one manually. Most people don't. Most people assume they're fine. And most people are quietly losing commissions as a result.
The Real Cost: Let's Do the Math
Let's say you run a modest affiliate blog with 300 posts. Each post has an average of 3 affiliate links — so 900 links total. That's not unusual for a niche site that's been running a couple of years.
Studies on link rot suggest that roughly 5–10% of links on the average website break within a year. For affiliate sites, where merchants frequently update URLs and exit programs, that figure can be even higher.
At a conservative 5% breakage rate, you've got 45 broken links sitting on your site right now.
Now let's say each working affiliate link generates an average of $2/month in commission (some links will be much higher, some much lower — this is just an average). Forty-five broken links means you're potentially leaving $90/month on the table.
Over a year, that's $1,080 in lost commission — from a problem you never knew existed.
For bloggers with larger sites or higher-converting links, the numbers get considerably worse. A travel blogger with 150 hotel affiliate links where a single booking can earn $30–$50 in commission? A broken link on a popular review post could cost hundreds per month, not tens.
Why Checking Manually Doesn't Work
The obvious solution sounds simple: just go through your links and check them. But anyone who's tried this quickly realizes why it doesn't scale.
Clicking through 900 links is tedious even once. Doing it regularly — monthly, or even quarterly — is simply not sustainable alongside everything else that goes into running a content site.
There's also a subtler problem: many broken affiliate links don't look broken. They redirect to a homepage, or a "product not found" page that returns a 200 status code. When you click the link manually, you land somewhere — it just doesn't convert, and you don't get credited. Spotting that manually requires knowing exactly where each link is supposed to go and comparing it against where it actually goes now.
Most bloggers try manual checking once, find it overwhelming, and then just stop — hoping for the best.
How Brokenly Fixes This
This is exactly the problem Brokenly was built to solve.
Instead of clicking through your site manually, Brokenly reads your XML sitemap, discovers every page on your site automatically, and then scans each page for affiliate links. It checks every link's status on a schedule — daily on the Pro plan, weekly on the Blogger plan — and alerts you by email the moment something breaks.
You get a dashboard that shows you the full picture at a glance: how many links are healthy, how many are broken, and exactly which pages they live on. No more guessing. No more manual spot-checks. No more quietly losing money to a problem you didn't know existed.
When a link breaks, you get an email right away. You can log in, see exactly which link failed and where it appears on your site, and fix it before it costs you significant commissions.
It takes a few minutes to set up — add your sitemap URL, and Brokenly handles the rest. From that point on, your affiliate links are monitored automatically, in the background, without you having to think about it.
Stop Leaving Money on the Table
Broken affiliate links are a silent killer for affiliate blogs. They don't announce themselves. They don't trigger alerts. They just quietly stop converting while your site looks completely normal from the outside.
The good news is it's a fully solvable problem — you just need a tool that watches your links for you.
If you're running an affiliate site and you've never systematically checked your links, there's a reasonable chance some of them are broken right now. The question is how long you're willing to let that continue before doing something about it.
