How to add your tag to Amazon.ca links

A practical walk-through of Amazon Associates Special Links on amazon.ca: the tag parameter, ASINs, messy product URLs, and a faster way to build the link. Not affiliated with Amazon.

If you are in the Amazon Associates programme for Canada, a product URL only pays you when it carries your tracking ID. That ID is the “tag” (sometimes called a store ID) you were issued in Associates Central. A typical ID looks like yourstore-20 — the placeholder used here is an example, not a live account.

The shape of a clean Amazon.ca Special Link

The shortest reliable form is:

https://www.amazon.ca/dp/ASIN?tag=yourstore-20

Replace ASIN with the product’s 10-character identifier and yourstore-20 with the tracking ID from your own Associates account. That tag= query parameter is what associates the click with you, provided the rest of the link stays a valid Special Link under the programme rules.

Find the ASIN

On a standard product page the ASIN appears in the URL after /dp/, /gp/product/, or a mobile path such as /gp/aw/d/. It is also listed in the product details section. An ASIN is exactly 10 letters and numbers. If you only have a search-result URL, open the product page first so the address contains one of those paths.

Short links such as amzn.to or a.co hide the ASIN. Open them once, then copy the full amazon.ca address — or use a retag bookmarklet on the product page.

Add the tag without breaking the URL

• If the URL has no query string yet, append ?tag=your-id.
• If it already has a ? and other parameters, add &tag=your-id (or replace an existing tag value so only your ID is credited).
• Do not use someone else’s tracking ID. Do not ship a “default” tag that is not yours.

Example, starting from a plain product URL:

https://www.amazon.ca/dp/B08N5WRWNW
https://www.amazon.ca/dp/B08N5WRWNW?tag=yourstore-20

You can also start from the ASIN alone and build the link from scratch. That is usually cleaner than keeping a long title slug and a pile of tracking parameters you do not need.

A faster way: use the TagLink Kit demo

Hand-editing is fine for one link. For a stack of ASINs it gets slow and easy to typo. The free TagLink Kit demo on this site is an Amazon.ca affiliate link generator that runs in your browser:

1. Enter your own Associates tracking ID (saved only in this browser).
2. Paste an ASIN or a full amazon.ca product URL.
3. Copy the tagged link. Optionally add UTM parameters for your own analytics.

The demo also builds up to three bulk ASINs. The downloadable kit (CAD $19) unlocks unlimited lists, CSV/TXT import, and Markdown or HTML export, and it works offline after you open the local file.
