If you run an affiliate website, you depend on links to generate revenue. When those links break, you lose money. This is straightforward. So here is a question worth asking: why does no affiliate network send you an alert when one of your links stops working?
Awin does not do it. CJ does not do it. Amazon Associates does not do it. ShareASale, Impact, TradeTracker, Daisycon, Bol.com Partner Program: none of them. Not one major affiliate network offers automated broken link detection and alerting as a standard feature for publishers.
This is not an oversight. It is the predictable outcome of how incentives are structured in the affiliate ecosystem.
How the money flows
To understand why networks behave the way they do, you need to understand who pays whom.
The affiliate chain has three parties:
- Merchants (advertisers) who sell products and pay commissions on sales
- Networks (Awin, CJ, Amazon, etc.) who provide tracking infrastructure and take a fee on each transaction
- Publishers (content creators, bloggers, review sites) who drive traffic through affiliate links
The money flows like this: a visitor clicks a publisher's affiliate link, buys a product from the merchant, the merchant pays the network a commission plus a fee, and the network passes the commission (minus their cut) to the publisher.
Every party in this chain gets paid only when a transaction happens. No click, no sale, no money for anyone. This seems like it would align everyone's interests. It does not.
The incentive asymmetry
When an affiliate link breaks, here is what each party experiences:
The merchant loses nothing. If the product page is gone, the product was probably discontinued anyway. The merchant was not going to sell that product regardless of whether the affiliate link worked. If the URL structure changed, the merchant's own marketing channels (email, paid ads, organic search) have already been updated. The affiliate link is a third party's problem.
The network loses nothing. Networks earn a percentage of each transaction. No transaction, no fee. But also no cost. The network does not pay anything when a link breaks. Their infrastructure continues running. Their other publishers continue generating transactions. One broken link on one publisher's site is noise in a system processing millions of clicks daily.
The publisher loses everything. For the publisher, a broken affiliate link means traffic that would have converted is hitting a dead end. The content still ranks. Visitors still click. But the link leads nowhere useful, and the commission that should have been earned is gone. The publisher bears 100% of the financial impact.
This is the core of the problem. The party with the most to lose has the least information about link health. The parties with the information (networks can see click-through rates dropping, merchants know when they restructure URLs) have no financial reason to act on it.

What networks could do but don't
It is not technically difficult to detect broken affiliate links. The data is already flowing through network systems. Here are capabilities that networks could offer but generally do not:
Network capabilities that don't exist
Click-to-conversion ratio monitoring. Networks track both clicks and conversions. If a link that historically converted at 3% suddenly drops to 0% while still receiving clicks, something is likely broken. Networks could flag this automatically. They do not.
Destination URL validation. Networks could periodically check whether the merchant landing pages that publishers link to still exist and still contain the expected product. This is a standard web crawling operation. Networks do not offer it.
Merchant change notifications. When a merchant restructures their URL scheme, updates their product catalog, or changes their deep linking format, the network could notify affected publishers. Networks do not do this consistently, if at all.
Link health dashboards. Networks could surface a simple view showing which of your links are healthy and which might be broken, based on HTTP status codes, redirect chains, and conversion data. No major network offers this as a standard publisher tool.
None of these would be expensive to build relative to the engineering resources that major networks already deploy. The technology is straightforward. The obstacle is not capability. It is priority.
The API problem
Some publishers try to monitor their own links programmatically. This introduces another friction point: many networks make it difficult to audit your links at scale.
Amazon Associates, the largest affiliate program in the world, provides limited API access for publishers. Bulk-checking your Amazon affiliate links for validity requires scraping or manual checking, both of which run into rate limits and terms-of-service issues.
Other networks offer APIs, but they are typically designed for reporting (how much did I earn?) rather than diagnostics (are my links still working?). There is no standard API endpoint across networks that lets a publisher ask: "Here are my 500 links. Which ones are broken?"
This means that even publishers who want to proactively monitor their links face significant technical barriers. The infrastructure to check links exists as a concept, but the networks have not built the interfaces to support it.
It's not malice, it's math
It would be easy to frame this as networks being negligent or hostile toward publishers. That framing would be wrong. Networks are not withholding link health data out of ill intent. They are simply responding rationally to their own incentive structure.
Building and maintaining a link health monitoring system for publishers would cost money. Engineering time, infrastructure, support resources. The return on that investment, from the network's perspective, is indirect at best. A publisher whose links work slightly better generates slightly more commissions, which generates slightly more fee revenue for the network. But the network cannot easily measure that incremental gain, and it is spread across thousands of publishers.
Compare that to the other things networks invest in: fraud detection (protects their revenue directly), merchant onboarding (grows their inventory), attribution technology (increases conversion attribution accuracy, which makes merchants happy). Each of these has a clearer ROI than "help publishers find their broken links."
This is not a conspiracy. It is a market gap created by misaligned incentives. The party that needs the solution most (publishers) is not the party that controls the infrastructure (networks), and the party that controls the infrastructure has limited financial motivation to build it.
What publishers actually need
Since networks are unlikely to solve this problem, publishers need to solve it themselves. That requires tools built specifically for the publisher's perspective, not adapted from the network's perspective.
A useful link health monitoring system for publishers would need to:
- Work across networks. Most publishers use multiple affiliate networks. A tool that only checks Amazon links or only checks Awin links solves a fraction of the problem. Publishers need a unified view across all their affiliate relationships.
- Detect soft failures. Standard HTTP status code checking (is it a 200 or a 404?) is insufficient. Many broken affiliate links return 200 OK with a "product not found" page. Detection needs to go deeper than status codes.
- Show revenue impact. Knowing that 15 links are broken is useful. Knowing that those 15 links were generating an estimated $2,000 per month is actionable. Publishers need link health data tied to financial context.
- Run continuously. A one-time audit finds today's broken links. But links break every week. Monitoring needs to be ongoing, with alerts when something changes.
- Be publisher-controlled. The data about which links are broken and what revenue is at risk belongs to the publisher. It should not sit behind a network's dashboard that the network can change, restrict, or discontinue.
What a publisher-side solution needs
The structural takeaway
The affiliate link ecosystem has a monitoring gap that exists for structural reasons, not technical ones. Networks sit in the middle of the value chain, but their business model does not require them to ensure link health for publishers. Merchants have no visibility into (and no responsibility for) how publishers link to their products. Publishers bear all the risk but have the fewest tools.
Understanding this incentive structure matters because it explains why waiting for networks to solve the problem is not a viable strategy. The solution will come from outside the existing network infrastructure, built by and for the people who actually lose money when links break.
The question for publishers is not whether their links are breaking. They are. The question is whether they want to know about it.
