Your Partner Tag and Marketplace

Docs › Getting started

These are the two smallest fields in the plugin and the two that decide whether a click earns anything. Every link the plugin builds — from the API, from a third-party provider, from free no-API mode — is assembled from the tag and marketplace saved here.

In one lineAffiliate Pro → Amazon API. Partner tag is your Associates tracking ID, like yoursite-20. Marketplace is the Amazon domain that tag belongs to. They must match each other.

The partner tag

Your partner tag — Amazon calls it a tracking ID — is the string appended to every product link as ?tag=. Without it a link still works, still sends the visitor to Amazon, and pays you nothing.

Find it in Amazon Associates under your account name in the top right, or in the sidebar of the Associates dashboard. It looks like a site name, a hyphen and a number:

yoursite-20      ← US
yoursite-21      ← UK
yoursite-0e      ← Germany

The numeric suffix is not decoration. It encodes the marketplace, which is why a US tag on a UK link is a link that tracks nothing.

You can create more than one tracking ID in Associates and use a different one per site or per section. That is the cleanest way to know which property is actually earning, because Amazon reports by tracking ID. The plugin uses one tag per install.

The marketplace

The marketplace is the Amazon domain your links point at. Nineteen are supported:

Region Marketplaces
Americas amazon.com (US), amazon.ca, amazon.com.mx, amazon.com.br
Europe amazon.co.uk, amazon.de, amazon.fr, amazon.it, amazon.es, amazon.nl, amazon.pl, amazon.se, amazon.com.be
Asia Pacific amazon.co.jp, amazon.com.au, amazon.sg, amazon.in
Middle East amazon.com.tr, amazon.sa

Pick the one your Associates account and partner tag were issued for. This is not a guess about where your readers live — it is a statement about which Amazon programme you joined.

Every link, whatever produced it, comes out in this shape:

https://<marketplace>/dp/<ASIN>?tag=<partner-tag>&linkCode=ll1

So with a marketplace of www.amazon.co.uk, a tag of yoursite-21 and ASIN B08N5WRWNW:

https://www.amazon.co.uk/dp/B08N5WRWNW?tag=yoursite-21&linkCode=ll1

Change either field and every link on the site changes with it, immediately, including ones in posts published years ago. That is the point of storing them centrally rather than in each shortcode.

Checking it worked

  1. Publish a product box on any page — see publishing your first product box.
  2. Hover the button and read the URL in the browser status bar. Confirm the domain is your marketplace and tag= is your tracking ID, spelled exactly.
  3. Click it. On the Amazon page that opens, the tag should survive in the address bar.
  4. Check Associates reporting the next day. Clicks appear against the tracking ID within about 24 hours.

A tag that looks right but reports nothing is usually one of nine causes, and only two of them are the tag itself. Work through the nine causes in the order to check them rather than guessing.

Visitors from other countries

A UK reader clicking a .com link usually lands on a page they cannot buy from, and Amazon’s own redirect does not carry your tag. Sending each visitor to their own marketplace with a tag that works there is a separate feature, and the reasoning — including why redirecting alone earns nothing — is in localising Amazon affiliate links by country.

Common questions

Where exactly do I find my tracking ID?

In Amazon Associates, top right under your account name, or in the dashboard sidebar. If you have several, the one shown by default is your primary. Any of them works, and using a distinct one per site makes reporting far easier to read.

Can I change the tag later without breaking old posts?

Yes. Links are assembled at render time from the saved setting, so changing it updates every product box on the site at once. Plain HTML links you typed by hand are the exception — those carry whatever tag you typed.

What if my tag is right but the marketplace is wrong?

Links point at the wrong Amazon and your tag is not valid there, so clicks are not attributed. Fix the marketplace field; nothing else needs editing.

Does the plugin add rel=”nofollow” and open links in a new tab?

Both are settings on the Display tab, applied to every generated link. Affiliate links should carry a sponsored or nofollow relationship — that expectation, and the disclosure that goes with it, is covered in disclosure requirements.
