When a merchant switches affiliate networks, the tracking links on your pages are the first assets at risk. Many keep returning a normal page load while the tracking path behind them is dead, redirected to a generic homepage, or no longer attached to an active program. This article explains what changes during a network migration, how to find affected monetized anchors, and how to sort them into Broken, Needs Attention and Healthy so the repair order is clear.
A note on scope: "merchant switched networks" also appears in payments, where it describes a business changing card processors or payment networks. This article covers the affiliate marketing meaning: an advertiser (the merchant) moving its program from one affiliate network to another, or to an in-house platform.
TL;DR
- A merchant that changes networks usually leaves old tracking links dead, often with no notice to the publisher.
- Status codes alone are insufficient: a link can return 200 OK and still land on a homepage, a discontinued product, or a path with no evident tracking.
- Classify every link as Broken, Needs Attention or Healthy, and keep confirmed failures separate from items requiring manual review.
- Prioritize by page traffic and link position, then replace links on the pages where qualified clicks are currently being lost.
- An audit identifies and documents issues; the publisher decides what to change.

What actually changes when a merchant moves networks
An affiliate link is rarely a link to the merchant. It points to a tracking domain operated by the network, which records the click and then forwards the visitor to the merchant. The link therefore depends on three things staying aligned: the network's tracking domain, the merchant's program on that network, and the publisher's relationship with that program.
When the merchant only changes its own website domain within the same network, the network typically redirects automatically, because the link points at the network's domain rather than the merchant's. A network switch breaks that assumption. The old network's tracking domain no longer has an active program to forward to, and the same source reports that the old link usually dies when a program moves networks or shuts down without a managed handover.
Some migrations are managed. When Rakuten Advertising and impact.com announced a transition for advertiser clients, Rakuten stated that publisher relationships would carry over and that tracking would continue to work for those who join the new platform. That describes one coordinated case. It does not describe the typical independent switch, and it still leaves the publisher with a task: confirming that each link on each page behaves as intended after the cutover.
Why the failure is hard to see
Three behaviors make post-migration breakage easy to miss:
- Silent redirects. The old tracking URL resolves, then forwards to the merchant's homepage. The page loads, the status is 200 OK, and the reader sees a store rather than the product the article recommended.
- Partial transitions. Some links in a program are redirected during a migration window while others, such as deep links or links to individual creatives, are not.
- Unverifiable tracking. The visitor reaches the right product, but the click passes through a path that no longer shows the identifiers the new network expects. From the outside, such a link is neither confirmed broken nor confirmed healthy.
The three failure patterns, by evidence type
A link audit after a network switch separates findings by what the evidence supports, not by what is assumed.
| Pattern | What the audit observes | Classification |
|---|---|---|
| Dead tracking domain | Error response, timeout, or domain no longer resolving | Broken |
| Redirect to generic homepage | 200 OK after a redirect chain ending on a root page, not the product | Needs Attention |
| Discontinued or unavailable product | Page loads, product listed as unavailable or removed | Needs Attention or Broken, depending on the evidence |
| Tracking path changed | Old network parameters absent in the redirect chain, new ones not evident | Needs Attention |
| Product page loads, path consistent with the active program | No contrary evidence found | Healthy |
Two cautions apply to this table. First, "Healthy" means no evidence of a problem was found at the time of review. It does not certify that commissions are being credited, which only the network's own reporting can show. Second, the Needs Attention class exists precisely because a redirect to a homepage can be intentional, so it calls for a human decision rather than an automatic conclusion.
How to find affected links on your own site
A publisher with a few dozen links can run a manual check. The sequence below applies whether you do it yourself or commission a review.
Step 1: Build the merchant and network inventory
Export every outbound link from the site and group them by tracking domain. This produces a list of networks and, within each, a list of merchants. The grouping shows which merchants share a network, which matters because a single network-level change can affect many anchors at once.
Step 2: Identify merchants that may have moved
Check your network dashboards for program notices, closed programs and removed advertisers. Check the merchant's own affiliate or partner page, which usually names the current network. Merchants that no longer appear in a network where you previously held an approval are the first candidates.
Step 3: Follow each redirect chain to its end
For each link, record the full chain of hops, the final URL and the final status code. A chain that ends on the expected product page is a reasonable signal. A chain that ends on a root domain, a search page, or a category page is not. Chains that pass through a tracking domain different from the one in the original link indicate that a redirect has been put in place, which should be documented.
Step 4: Check the destination, not just the response
The destination must still sell the thing the anchor promises. Look for out-of-stock notices, product removal messages, and substitution pages. A 200 OK on a page that says the item is unavailable is a commercially unhealthy link.
Step 5: Rank by exposure
Sort findings by the traffic of the hosting page, the prominence of the anchor (first paragraph, comparison table, call-to-action button) and the number of pages carrying the same link. A single dead link in a template or a widely reused table can outweigh dozens of isolated ones.
Prioritizing the repair list
Not all findings carry equal weight. A defensible order is:
- Broken links on high-traffic pages. Confirmed failures where qualified clicks currently reach an error.
- Needs Attention links in prominent positions. Homepage redirects and unavailable products in comparison tables or buttons.
- Broken links on low-traffic pages. Confirmed, but lower exposure.
- Needs Attention links in low-prominence positions. Review when time permits.
- Healthy links. Recheck on a schedule, since a merchant's status can change again.
For each item in the first two tiers, the publisher has three options: replace the link with a current one from the merchant's new network, substitute an alternative merchant for the same product category, or remove the monetized anchor and keep the editorial content. The choice depends on whether the merchant remains commercially relevant to the article.
What a network switch does not tell you
Several conclusions are tempting and unsupported:
- That revenue was lost, or how much. A broken link shows that clicks reached a dead end. It does not quantify earnings that would have resulted.
- That a loading link is earning. A link that reaches the right product through a plausible path has no observed fault, yet crediting can only be confirmed in the network's reports.
- That every redirect is a failure. Some merchants maintain redirects deliberately during migration windows. These deserve a note and a recheck date.
This is why a well-structured report distinguishes confirmed findings from review items and records the evidence for each, rather than presenting a single list of problems.
Our perspective
We built our audit around one observation: most link checkers stop at 404 errors, and a network switch is exactly the event that produces links they cannot flag. The old tracking path loads, returns 200 OK, and delivers the visitor to a homepage or an unavailable product. Nothing in a status-code report distinguishes that from a functioning link.
Our approach therefore evaluates links that still load for commercial viability, not only for availability. Each finding is classified as Broken, Needs Attention or Healthy, and the report separates clear fixes from items needing manual review, so that a publisher does not spend an afternoon on links that were never at fault or skip links that quietly stopped working.
We are also specific about limits. We do not verify commission crediting, we do not claim recovered revenue or confirmed lost income, and we do not repair links. We identify them and supply the evidence; the publisher decides what to fix and in what order. That boundary is deliberate, because the party able to confirm crediting is the network, and the party able to change a link is the site owner.

Getting a prioritized list for an older content library
Manual review is practical for a small site. For a library with years of posts, a merchant that changed networks may be referenced in dozens or hundreds of places, across templates, tables and old articles that still attract search traffic.
The Affiliate Link Audit Full Audit is priced at 97 USD one-off and delivers a prioritized action plan with suggested replacements, with findings classified as Broken, Needs Attention or Healthy. Every engagement can begin with a free sample, which lets you review the evidence format before deciding on the full scan. You can inspect the structure of a finished report in the sample report, and publishers with multiple domains can read the publisher overview. Background data on how links degrade across monetized sites is collected in the affiliate link health research.
Preventing the next surprise
Network switches will recur, so the practical safeguard is routine rather than reactive.
- Maintain a merchant register. Record each merchant, its network, your approval date and the date of the last verification.
- Subscribe to program notices. Network messages about closing or migrating programs are the earliest signal, and they are easy to overlook in a busy inbox.
- Recheck after any notice. When a merchant announces a transition, schedule a link review for after the stated cutover window, not before.
- Centralize links where possible. Managing recurring merchant links in one place (a link-management plugin or a shared snippet) reduces the number of edits required when a URL changes.
- Review on a calendar. A quarterly pass over the highest-traffic pages catches most drift without a full-site exercise.
FAQ
Will old affiliate links keep working after a merchant changes networks?
Sometimes, but this should not be assumed. In a managed migration, the network or the merchant may keep redirects active for a period, as Rakuten described for its transition to impact.com. Where the move is unmanaged, the old link usually dies, so each link should be checked individually.
How do I know which network a merchant uses now?
Start with the merchant's own affiliate or partner page, then check the program directory inside the networks where you hold accounts. If the merchant has disappeared from a network where you were approved, treat its links as candidates for review. Network dashboards also tend to post notices about closed or migrating programs.
Does a 200 OK response mean an affiliate link is healthy?
No. A 200 OK shows that a page loaded, not that it is the intended product or that the tracking path is still attached to an active program. Links that redirect to a homepage or land on an unavailable product are commercially unhealthy despite a normal response, which is why they belong under Needs Attention for review.
Can an audit confirm that I am still earning commissions on a link?
No. An audit documents what can be observed from outside: redirect chains, destinations and product availability. Commission crediting can only be confirmed in the network's own reporting, so the audit supplies evidence and the publisher decides what to change.
