Affiliate Link Rot: What Happens to a Tracking Link When a Retailer Changes Domains or Networks?

Affiliate link rot: the short answer

Affiliate link rot happens when a retailer changes its domain, switches affiliate networks, or gets acquired, and an older tracking link stops tracking correctly as a result. If the retailer only changes its own domain within the same network, the network usually redirects automatically, because the link itself points at the network's own tracking domain, not the retailer's. If the retailer switches networks entirely, or the program shuts down without a managed handover, the old link usually dies — with no warning to either the creator or the brand, and no party is obligated to prevent it. That's a different problem from what happens when an influencer changes their own username — here it's the retailer's or the network's infrastructure that changes, not the creator's.

Why it happens: three types of change that can hit an old link

An affiliate tracking link isn't just a URL to the retailer's website — it's a URL encoded to recognize a specific creator or publisher and forward that click to the retailer's site while also setting a tracking cookie or click ID. See how influencer tracking actually works for the mechanics themselves, and choosing an affiliate tracking network for how the major global networks are structured. That encoding can break in three different ways:

• The retailer changes its own domain but stays with the same affiliate network. Because most affiliate links point at the network's own tracking domain (e.g. an adtraction or awin subdomain) rather than directly at the retailer's URL, the network can usually update where the link sends the customer without the link you've shared ever changing.
• The retailer changes which network manages the program. This is the type of change that most often goes wrong. Per general affiliate-industry practice, a link becomes invalid once the retailer leaves the network it was issued from — because the link contains a publisher or partner ID that only means something inside the network that created it. A link from the old network doesn't automatically point at the new one.
• The program shuts down entirely, or the retailer gets acquired, with no managed transition for the existing links. There's no shared rule here — it depends entirely on whether the acquiring party chooses to invest in preserving the old links, or simply lets them die.

Comparison: what happens to the link in each scenario

Two real examples of network change — with two different outcomes

This Academy has already documented two concrete network consolidations that show how the same type of event can end very differently for the existing links:

Adservice into Adtraction (Danish example). Adservice, the Danish affiliate network founded in Aarhus in 2007, was acquired by Swedish Adtraction in February 2023 and fully migrated into Adtraction's own platform from Q2 2024 — adservice.com now redirects straight to adtraction.com, and there's no longer a standalone Adservice login. See the full breakdown of Adtraction, Tradedoubler and Adservice and Partner-ads vs. Adtraction for the Danish network landscape that acquisition sits inside. Per this Academy's own research, existing Adservice customers and any third-party integrations built directly against Adservice's own API had to be checked and updated against Adtraction's new infrastructure after the migration — so this wasn't a pure "nothing to do" transition for every link in the chain.

ShareASale into Awin (global example). Awin acquired ShareASale back in 2017, but the actual platform merger didn't happen until 2024-2025, with the old ShareASale platform closing entirely by the end of 2025. Per Awin's own communication to existing ShareASale users: "You don't need to install new tracking, we'll automatically switch that over for you" — an explicit promise that existing tracking links and publisher relationships were carried over automatically, without the publisher needing to replace links in already-published content.

The point isn't that one provider is better than the other — it's that the same type of event (one network absorbing another) can produce anything from "nothing to do" to "check and update it yourself," depending on how much work the acquiring party puts into the transition. You can't assume the best-case outcome without confirming it.

How to audit your own older content for dead links

• List every piece of evergreen content with an affiliate or tracking link older than 6-12 months — blog posts, YouTube descriptions, old Linktree entries, printed materials.
• Click each link manually on a regular schedule and confirm it lands on the expected page — not an error page, a generic homepage, or a page missing the expected tracking parameter in the URL.
• Track whether a retailer or network you work with announces an acquisition or a platform change, and proactively ask for an updated link instead of waiting for conversions to simply stop.
• Prioritize content that's still driving traffic — an old post with ongoing views is far more expensive to overlook than one nobody sees anymore.
• Note whether the link points directly at the network's tracking domain, or goes through a centrally managed redirect — see the next section for why that makes a real difference to how much work a future change requires.

Why a centrally managed redirect reduces the risk

The structural reason link rot is so expensive to catch late is that a raw affiliate link is typically pasted directly into every individual piece of content that uses it. If the link breaks, every place it's shared has to be found and fixed one at a time. A tracking link that instead runs through a centrally managed redirect — meaning the visible link in the content points at an address you (or your influencer platform) control, which then forwards on to the retailer's current destination — makes it possible to fix the destination in one place, without editing every old post individually. It doesn't guarantee an acquisition or a network change won't happen; it just moves the fix from "find and edit all the old content" to "update one destination." Some networks also build in their own safety mechanisms of a different kind — Awin's own "Link Status" system, for example, automatically redirects to a retailer-chosen fallback URL if the retailer's account balance goes negative, so a publisher doesn't lose the traffic entirely in that situation. That's not the same as a guarantee that a link survives a full network switch or an acquisition, though — it's a separate mechanism for a different, narrower failure mode.

Worked example (hypothetical)

The figures below are made up to illustrate the logic — not a real measurement or a Make Influence customer case.

An evergreen blog post links to a retailer through an affiliate link. The post has historically generated a hypothetical average of 40 clicks a month, with an assumed 5% conversion rate and an average commission of DKK 60 per sale:

• Sales per month (hypothetical): 40 × 5% = 2 sales
• Commission per month (hypothetical): 2 × DKK 60 = DKK 120

The retailer switches networks in January, and the link dies the same month without anyone noticing until June. Over the intervening five months (February-June), the post keeps generating the same 40 clicks a month, but DKK 0 in commission — not because the traffic disappeared, but because every click now either fails or lands with no tracking. The hypothetical loss is 5 × DKK 120 = DKK 600 in missed commission for this one post alone — an amount that grows with every additional old post and every extra month before anyone catches it.

Decision framework

IF you maintain evergreen content with affiliate links older than 6-12 months → put a recurring check on the calendar, rather than relying on someone noticing by chance.

IF a retailer or network you work with announces an acquisition or a platform change → proactively ask for confirmation that your existing links still work, rather than waiting and seeing.

IF a link only appears in short-lived content (a Story, a single campaign push) → lower priority, since the link was never intended to keep working long-term anyway.

IF you're choosing between pasting a raw affiliate link directly or using a centrally managed redirect in evergreen content → choose the centrally managed redirect, precisely because it turns a future fix into one task instead of many.

Common mistakes

• Assuming a redirect is a given. It's each network's or retailer's own choice, not a rule — the ShareASale/Awin and Adservice/Adtraction examples above ended differently.
• Never revisiting old, evergreen content because it was "built once" and treated as finished.
• Treating a domain change and a network change as the same risk. A pure domain change within the same network is usually low risk; a network switch is high risk.
• Pasting a raw affiliate link directly into evergreen content instead of using a centrally managed redirect that can be fixed in one place.
• Catching it too late — because a dead link rarely triggers an error message to anyone; the traffic just quietly disappears from the reporting.

Make Influence's perspective

In our experience, link rot is one of the easiest failure patterns to miss, precisely because no system raises an alarm when it happens — there's no error message, just quietly declining numbers in a report that often get blamed on something else (seasonality, an algorithm change, waning interest). We recommend treating an affiliate or tracking link as a living part of the campaign material, not a one-time setup — especially for content meant to sit and keep driving traffic for a long time. A centrally managed tracking link, where the destination can be updated in one place, doesn't solve the underlying problem of retailers and networks changing — but it makes the fix dramatically cheaper when it happens.

FAQ

How long does an affiliate tracking link typically last?

There's no general figure for this, and this article doesn't invent one. In practice, the link lasts as long as the retailer's relationship with that particular network stays unchanged — that can be years, or it can change on short notice through an acquisition or a network switch.

Is it the same risk whether the retailer changes domain or changes network?

No. A pure domain change within the same network is usually low risk, because the link points at the network's own tracking domain. A switch of the network itself is high risk, because the link is typically tied to a publisher ID that only applies within the original network.

How do I check myself whether an old link is dead?

Click it manually and confirm it lands on the expected page with the expected tracking parameter in the URL — an error page or a generic homepage with no parameters are both signs the link is broken.

Is this the same problem as when an influencer changes their own username?

No, it's a different mechanism. See what happens to tracking links when an influencer changes their username for the situation where it's the creator's own platform account, not the retailer's infrastructure, that changes.

Does a dead link affect sales that already happened?

No. Already-tracked and paid sales are unaffected. It's only clicks that happen after the link breaks that lose their tracking, and with it the commission.

Can you choose a network that guarantees links never break on an acquisition?

Not based on this research. Even in the best-documented example here (ShareASale/Awin), the outcome came down to the acquiring party's own choice and communication — not a published, general guarantee from the network.
