Short Links for Affiliate Marketing: A Practical Guide

Affiliate links are the least attractive links on the internet. They're long, they carry an ID and a sub-ID and a click token, they change when the program changes, and they live in places you can't easily edit — three-year-old video descriptions, old posts, printed inserts. A short link in front of each one fixes the appearance, gives you a click count per placement the network doesn't provide, and turns "the program changed" from an afternoon of hunting through old content into one edit.

This guide is the practical setup, the measurement that actually tells you which placements earn, the maintenance that keeps years-old links paying, and the compliance rules that don't change because the link got shorter.

How the pieces fit#

The reader taps your short link. The shortener counts the click and redirects to your full affiliate URL, exactly as the network gave it to you — ID, sub-ID, tracking parameters and all. The network's own tracking runs at the destination, unchanged. Two counts result: clicks, which you own, per short link; and sales, which the network reports, per affiliate ID or sub-ID. Put them side by side and you have earnings per placement, which is the number the whole business runs on.

Nothing about this alters the network's tracking. The short link is a door; the affiliate URL is behind it, unchanged.

Setting it up#

1. Use your own domain#

go.yourname.com/camera reads as a recommendation from you. A random code on a generic shortener reads as a trap, and on some platforms is filtered as one. A custom domain is one DNS record and it does more for click-through than anything else on this page.

2. One short link per placement#

Not per product — per placement. The same camera gets /camera-yt for the video description, /camera-blog for the review, /camera-nl for the newsletter, /camera-ig for the bio. Same affiliate URL behind all of them (or a different sub-ID per placement, if the network supports it — see measuring, below).

This is the same rule as every other channel, and it's the only way a click count means anything.

3. Name them so you'll find them in three years#

Old affiliate content keeps earning long after you've forgotten making it. Aliases in plain words — /camera-yt, not /c1 — and a description on each link ("Sony a7 · YouTube review · March 2026 · Amazon") mean the day the program changes, you can search for every placement of that product and fix them in minutes. The naming guide has the conventions.

4. Test one end to end#

Before scaling, click a short link, complete a test path at the merchant if the program allows it, and confirm the click shows up in the network's reporting. Most problems — a stripped parameter, a program that forbids redirects — show up on the first link.

Measuring: clicks you own, sales they report#

Networks tell you sales, sometimes clicks, per affiliate ID. What they don't tell you is which of your placements sent the sale, unless you use a sub-ID (called SubID, sid, tag, ref or similar depending on the network) — a value you append to the affiliate URL that comes back to you in the report.

The clean pattern is to make the sub-ID match the short link's alias:

go.yourname.com/camera-yt   →  network.com/?id=YOU&subid=camera-yt
go.yourname.com/camera-blog →  network.com/?id=YOU&subid=camera-blog

Now the shortener's statistics show clicks per placement, and the network's report shows sales per placement, and the two join on the alias. Earnings per click, per placement, without a spreadsheet of lookups.

What the shortener's numbers add that the network's don't:

• Clicks by hour and day. A video's link spikes at upload and decays; a search-ranking review's link is steady for years. That shape tells you where to put effort.
• Country and device. If half your clicks are from a country the program doesn't pay for, you've found a leak — and a reason to re-point those readers to a program that does.
• Bot filtering. Preview crawlers and scanners are removed before counting; the number is people. It'll be lower than a raw count and it'll be right.
• Destinations you don't control. The merchant's page is theirs; the click is yours anyway.

Visitor IPs are never stored by Xlyl, which matters for an affiliate: you get the per-click detail — which placement, which country, which device — with no address in the database to leak, and nothing to reconcile with privacy rules beyond the disclosure you already make.

Maintenance: when programs change#

They always do. The product is discontinued, the commission drops, the network switches, the merchant leaves. With a raw affiliate URL in three hundred places, each is now a dead or non-paying link until you find it.

With a short link per placement, the fix is one edit per placement — or one edit total, if a group of placements points at the same alias. The video description from 2024 still says go.yourname.com/camera; today it goes to the current camera on the current program. Editable destinations are the single largest reason affiliates use a shortener.

Some habits that make this painless:

• Re-point, don't delete. An old link that 404s loses the click and the trust. Point it at the replacement product, or at your current recommendation in that category.
• Set an expiry only on links that should die — a launch bonus, a coupon with an end date. Expiring links free the alias and stop the click cleanly.
• Keep a link for each product category (/best-camera) in addition to the per-placement links, and point it at whatever you currently recommend. It's the link you'll paste when someone asks.
• Review the top-clicked links quarterly. They're where a broken program costs the most.

Compliance: what doesn't change when the link gets shorter#

Shortening a link changes how it looks. It changes nothing about your obligations.

Disclose the relationship where the link appears. Consumer-protection rules in most countries — and every major platform's own rules — require that affiliate relationships be disclosed clearly and close to the link, in language a reader understands. The US Federal Trade Commission's disclosure guidance for creators is the clearest plain-English statement of what "clear and conspicuous" means, and most other regulators land in the same place. "Affiliate link" or "I earn a commission if you buy through this link" in the post, the video description, the newsletter. Not in a footer, not behind the link, not on another page. A short link with no disclosure is the same violation as a long one with none.

Follow the program's link rules. Most networks allow redirects; some forbid "cloaking" (hiding the affiliate URL), some require their own link format, some ban certain placements (paid search on the merchant's brand is a common one). The program terms are the authority. If a program forbids redirects, use its links directly for that program.

Don't obscure the destination from the reader. A short link is fine; a short link whose surrounding text pretends the destination is something else is not. Say what it is: "the camera I use (Amazon, affiliate link)".

Keep the short link honest in social bios and stories — the platforms' own disclosure tools (paid partnership labels, #ad) apply to affiliate content on many of them.

None of this is onerous, and all of it is easier with links that say what they are: go.yourname.com/camera next to "affiliate link" is clearer than a network URL with a token in it.

Where short links help most, by placement#

The social guide covers each platform's handling of links; the QR guide covers the printed ones.

A setup you can finish this afternoon#

1. Add your domain on the domains page and check its DNS.
2. Pick an alias shape: /[product]-[placement].
3. For your ten best-earning placements, make a short link each, with the sub-ID matching the alias and a description naming the product, placement, date and network.
4. Replace the raw affiliate URLs in those placements with the short links. Test one.
5. Next month, put the shortener's clicks per link beside the network's sales per sub-ID.

If you have hundreds of placements, the API creates the links from a spreadsheet in a few lines.
