> How to add @codeqr/analytics to your WordPress site
With `@codeqr/analytics`, you can track lead and sale conversions on your WordPress site, enabling you to measure the effectiveness of your marketing campaigns.
You can add the `@codeqr/analytics` script to your WordPress website same way you would add Google Analytics script or any other JavaScript code.
Follow these steps to add the script to your site:
* On your WordPress dashboard, navigate to the **Theme Editor** section under the **Appearance** menu.
* Open the **Theme Header (header.php)** file on the right column.
* Paste the CodeQR analytics script in the header area.
* Click on the **Update File** button to save the changes.
```html theme={null}
```
If you're using [CodeQR Partners](/partners/quickstart) for affiliate management, you will also need to set up the `data-domains` property to enable [client-side click-tracking](/sdks/client-side/features/client-side-click-tracking).
```html theme={null}
```
Read the [client-side click-tracking guide](/sdks/client-side/features/client-side-click-tracking) for more information.
You can **verify the installation** with the following tests:
1. Open the browser console and type in `_CodeQRAnalytics` – if the script is installed correctly, you should see the `_CodeQRAnalytics` object in the console.
2. Add the `?cq_id=test` query parameter to your website URL and make sure that the `cq_id` cookie is being set in your browser.
If both of these checks pass, the script is installed correctly. Otherwise, please make sure:
* The analytics script was added to the `` section of the page
* If you're using a content delivery network (CDN), make sure to purge any cached content
## Concepts
You can pass the following props to the `@codeqr/analytics` script to customize its behavior:
The base URL for the CodeQR API. This is useful for [setting up reverse
proxies](/sdks/client-side/features/reverse-proxy-support) to avoid
adblockers.
The attribution model to use for the analytics event. The following
attribution models are available:
* `first-click`: The first click model
gives all the credit to the first touchpoint in the customer journey.
* `last-click`: The last click model gives all the credit to the last
touchpoint in the customer journey.
Custom properties to pass to the cookie. Refer to
[MDN's Set-Cookie documentation](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie) for
all available options.
Specifies the value for the `Domain` Set-Cookie attribute. This is useful
for cross-domain tracking. Example: `.example.com`
Specifies the `Date` object to be the value for the `Expires` Set-Cookie
attribute. Example: `new Date('2024-12-31')`
Specifies the number (in days) to be the value for the `Expires`
Set-Cookie attribute.
For example, to set the cookie window to 60 days (instead of the default 90 days), you can add the following to your script:
```html theme={null}
```
Specifies the value for the `Path` Set-Cookie attribute. By default, the
path is considered the "default path". Example: `/`
Configure the domains that CodeQR will track. The following properties are available:
The CodeQR custom domain for [referral program client-side click tracking](http://d.to/clicks/refer) (previously `data-short-domain`).
Example: `refer.codeqr.io`
The CodeQR short domain for tracking site visits.
Example: `site.codeqr.io`
An array of domains for cross-domain tracking. When configured, the existing `cq_id` cookie
will be automatically appended to all outbound links targeting these domains to enable
cross-domain tracking across different applications.
Example: `"codeqr.link, git.new"`
The query parameter to listen to for client-side click-tracking (e.g.
`?via=abc123`).
