Managing affiliate links without losing attribution

Why affiliate URLs are shaped the way they are

An affiliate link carries your identifier and often a sub-identifier for the placement, plus a redirect through the network so the click can be recorded and a cookie set. Every one of those components is load-bearing. Shortening the link is safe; rewriting or trimming any part of it is not, and a missing sub-id means a commission that cannot be traced back to the content that earned it.

Put the full affiliate URL as the destination and change nothing

The correct pattern is a short link whose stored destination is the complete, unmodified affiliate URL including every parameter. Do not strip parameters you do not recognise. Do not add your own parameters that might collide with the network's. The short link becomes a stable public handle; the messy URL stays private.

The advantage is being able to change the network later

Affiliate programmes end, terms change, and networks migrate. If every mention across two years of content points at a raw affiliate URL, changing programmes means editing every article. If they point at short links, it means editing a destination per product. This is the single strongest operational reason to route affiliate traffic through your own domain.

Sub-identifiers are where the learning is

Most networks accept a free-form sub-id parameter that comes back in their reporting. Use it to encode the placement: the article slug, the newsletter issue, the video. Without it you know you earned commission; with it you know which piece of content earned it, which is the only information that changes what you make next.

Disclosure and nofollow still apply

Wrapping an affiliate link in your own domain does not change your disclosure obligations, and it does not hide the relationship from anyone who looks. Keep disclosures visible and honest. On the technical side, mark affiliate links appropriately in your markup, and consider excluding the short-link path from indexing so search engines do not treat your redirect paths as content.

Test that the cookie is actually set

The failure mode is silent: the click works, the page loads, the visitor buys, and no commission appears because a redirect stripped a parameter or a browser blocked the network's cookie. Test a full purchase path yourself at least once per programme, and again whenever you change how links are built.

Watch for links that die quietly

Product pages get discontinued and affiliate URLs return errors or redirect to a generic home page, which usually pays nothing. Run a periodic check on every affiliate destination's final status code and final URL, and prioritise fixing the ones that still get clicks.
