# Set your affiliate tag

> The one setup step that decides whether your published pages earn anything.

<Warning>
  Read this before you publish your first page. A review page with the wrong tag looks
  completely normal, ranks normally, and gets clicked normally. It just pays somebody
  else, or nobody.
</Warning>

## What an affiliate tag is

Your Amazon Associates tracking ID. It usually looks like `yourname-20`. Amazon uses it
to work out which clicks came from you, and therefore which commissions are yours.

Every product link Guino puts on your page carries this tag. If it is missing or wrong,
the click still works and the customer still buys, but the sale is not attributed to you.

## Why this page exists

New Guino accounts are created with a placeholder tag called `example-20`. It is a
stand in, not a real Associates ID, and it belongs to nobody.

This means a brand new account can run the whole pipeline, produce a genuinely good
review page, publish it successfully, and earn nothing. Nothing about the page looks
broken, because nothing about the page is broken.

## Set it

<Steps>
  <Step title="Find your tag in Amazon Associates">
    Sign in to your Amazon Associates account. Your tracking ID is shown in the top
    navigation, and in **Account Settings** under **Manage Tracking IDs**. Copy it
    exactly, including the number on the end.
  </Step>

  <Step title="Add it in Guino">
    In Guino, open your affiliate tag settings and paste it in. Save.
  </Step>

  <Step title="Confirm it took">
    Open any review page you have already published and click one of your product
    links. The address you land on should end with your tag, like
    `amazon.com/dp/B0XXXXXXX?tag=yourname-20`.
  </Step>
</Steps>

## Pages you already published

Changing your tag does not rewrite pages that are already live. If you published
anything while the placeholder was still set, open each one in the
[Review Editor](/studio/review-editor) and publish it again. Publishing regenerates
the links with your current tag.

<Note>
  Guino also runs a readiness check right before you publish, and a missing or
  placeholder tag is flagged there as a blocker. That check is your safety net, but it
  only helps on pages you publish from now on.
</Note>

## Multiple tracking IDs

Amazon lets you create several tracking IDs so you can tell campaigns apart, for example
one for your blog and one for your YouTube channel. Guino uses one tag per account at a
time. If you switch, the change applies to pages you publish after the switch.

## What the links look like

Guino only ever writes plain, direct Amazon product links in this shape:

```
https://www.amazon.com/dp/PRODUCTCODE?tag=yourtag-20
```

No redirect chains, no link shorteners, no cloaking. Amazon requires affiliate links to
be direct and to be marked as sponsored, and Guino does both automatically. See
[Compliance](/reference/compliance).
