A migration does not have to affect your affiliate earnings, but it can if you overlook two things: the cloaked links created by a link-management plugin, and the traffic your content earns. Ordinary affiliate links are just outbound links with your tracking ID embedded, so they travel with your content and keep working, as long as the tracking IDs come across unchanged and any rel=sponsored or nofollow attributes are preserved. The risk is cloaked links: plugins like the popular link cloakers turn affiliate URLs into tidy internal redirects such as /go/product, and those redirects are plugin behavior, so on the new site they break and their clicks lead nowhere unless you rebuild the redirects or swap in the direct affiliate URLs. And since earnings track traffic, preserving your rankings preserves your commissions. WPBuildAI carries your affiliate links and tracking IDs across intact, rebuilds any cloaked redirect URLs so no link breaks, and maps every page URL to a verified 301 so the traffic that earns keeps arriving.

Plain affiliate links travel with your content

The reassuring part is that most affiliate links are not special. An ordinary affiliate link is just an outbound link to a merchant with your tracking ID embedded in the URL, and that is content, part of the page, so it migrates with the page. As long as the link and its tracking ID come across unchanged, the click still reaches the merchant and still attributes the commission to you. So for the common case of direct affiliate links written into your posts, a faithful content migration carries them intact, and there is nothing extra to do beyond confirming the IDs survived. This is the same reason your other outbound links move with the content, and it means the affiliate concern narrows to the specific cases that are not plain links.

The links that break are the cloaked ones. Many affiliate sites use a link-management plugin that hides long affiliate URLs behind tidy internal redirects, so a link reads as /go/product or /recommends/tool and the plugin redirects it to the real affiliate URL with your ID. That redirect is plugin behavior, not content, so when the plugin is gone, the cloak points nowhere and the click dies, which is exactly the kind of broken link a migration can introduce if unaddressed. You have two clean options: rebuild those redirects on the new platform so each cloak still resolves to the correct affiliate URL, or replace the cloaked links in your content with the direct affiliate URLs. Either way the click must reach the merchant with your ID attached, or that commission is lost.

Two details decide whether a surviving link still pays and still complies. First, the tracking ID: the commission attributes only if your affiliate or associate ID is present and correct in the URL, so confirm the IDs came across unchanged rather than being stripped or altered in the rebuild. Second, the link attributes: Google asks that affiliate and paid links be qualified with rel=sponsored, or at least nofollow, so preserve those attributes on migrated links and apply them to any you rebuild. A migration is a good moment to verify both, since a rebuild that quietly drops tracking IDs would break earnings invisibly, and one that drops rel=sponsored would leave your outbound links unqualified. Both are easy to keep when checked deliberately.

Earnings follow traffic, so protect the rankings

The largest lever on affiliate income is not the links at all; it is the traffic. Affiliate earnings are roughly your traffic times how well it converts times the commission, so the pages that rank and bring visitors are what actually generate income, and protecting their rankings protects your earnings, just as it does for AdSense revenue. Keep your URLs the same where you can, 301 the rest, and treat the migration as a careful site move so rankings hold. Since traffic and therefore commissions concentrate on a minority of pages, as the Ahrefs study shows, identify your top earning pages and make sure their URLs, redirects, and affiliate links are all correct first. The platform itself is not a ranking factor, per the Backlinko analysis, so a faithful rebuild keeps both the rankings and the income.

Verify the money path end to end after launch

Because affiliate income is easy to break invisibly, test it deliberately after launch. Pick your highest-earning pages and click their affiliate links, confirming each one reaches the merchant with your tracking ID in the final URL, not a broken cloak or a stripped ID. Check that any rebuilt cloak redirects resolve. Watch your affiliate dashboards in the days after the move for a drop in click-throughs, which would flag a broken link you missed. This end-to-end check is the affiliate equivalent of confirming a form submission arrives: the link can look fine on the page and still fail to pay if the ID or the redirect is wrong, so following the actual money path is what proves the migration preserved your earnings.

Steps to protect affiliate earnings in a migration

  1. Carry plain affiliate links across with their tracking IDs unchanged.
  2. Identify cloaked links from any link-management plugin.
  3. Rebuild cloak redirects or replace them with direct affiliate URLs.
  4. Preserve rel=sponsored or nofollow on affiliate links, and on rebuilt ones.
  5. Protect rankings: keep URLs, 301 the rest, prioritize top-earning pages.
  6. Test the money path after launch: real clicks reach the merchant with your ID.

Worked example: a review site that kept its commissions

Consider a product-review site earning through Amazon and other programs, using a link cloaker so every recommendation went through /go/ URLs. Migrating off WordPress, the team knew the cloaks were plugin redirects that would break, so they rebuilt each /go/ redirect on the new platform to point at the correct affiliate URL, tracking IDs intact, and confirmed rel=sponsored was preserved. They kept every page URL the same so rankings held, prioritizing the reviews that earned the most. After launch they clicked the top reviews’ links and watched them land on the merchant with the ID attached, then checked the affiliate dashboards for steady click-throughs. Commissions continued uninterrupted, because both the cloaked links and the traffic behind them had been protected.

Limitation: programs and disclosures are separate concerns

It is honest to bound this. A clean migration preserves the links, tracking, and traffic you have, but it does not manage the affiliate programs themselves: a program’s terms, your standing in it, geo-targeting features like regional link localization, and required disclosures are separate matters that the move does not touch. So keep your affiliate disclosures in place on the new site, confirm any region-localization features are reconfigured if you used them, and handle program-level issues directly with each network. The migration’s job is to make sure your existing, working affiliate setup does not break in the move; it is not a substitute for managing the programs, which remain your responsibility on the new platform as they were on the old.

Key points

A migration does not have to affect your affiliate earnings, but it can through two oversights: cloaked links and lost traffic. Plain affiliate links move with your content and keep paying if their tracking IDs and rel=sponsored attributes are preserved, while cloaked links from a link-management plugin are internal redirects that break unless you rebuild them or swap in the direct URLs. Earnings track traffic, so preserving rankings, keeping URLs and 301-ing the rest, protects commissions, and the platform itself is not a ranking factor. Verify the money path end to end after launch by clicking your top links and confirming they reach the merchant with your ID, and keep disclosures and program-level settings in order separately.
