Conversion Tracking

Conversion tracking lets you measure the actions visitors take on your site after clicking a Wortise ad — purchases, sign-ups, or any custom event you care about.

This page covers the standard JavaScript tag setup, alternative integration methods (image pixel and server-to-server), and the cookie used to attribute conversions.

Quick Start

Add the global snippet to ALL pages

Place this snippet in the <head> or at the top of the <body> on every page of your website:
```
<script async src="https://cdn.resources.wortise.com/sdk/wtag.js"></script>
<script>
  window.wDataLayer = window.wDataLayer || [];
  function wtag(){wDataLayer.push(arguments);}
  wtag('config');
</script>
```
This does two things:
- Loads the tracking script asynchronously (non-blocking).
- When a visitor arrives via a Wortise ad click, captures the click ID (wclid) from the URL and stores it in a first-party cookie.
Track conversions

On the page where a conversion happens (e.g., order confirmation, sign-up thank-you page), add:
```
<script>
  wtag('event', 'conversion', {
    type: 'purchase',
    value: 29.99
  });
</script>
```
Parameter Type Required Description
type string No Conversion type (e.g. purchase)
value number No Monetary value of the conversion

Parameter	Type	Required	Description
`type`	string	No	Conversion type (e.g. purchase)
`value`	number	No	Monetary value of the conversion

How It Works

A user clicks a Wortise ad and is redirected to your site with a ?wclid=xxx parameter in the URL.
The SDK detects this parameter and stores it in a _wcl first-party cookie (30-day expiry, scoped to your root domain).
When the user completes a conversion, the SDK reads the cookie and sends a request to the Wortise conversion endpoint.
The cookie works across subdomains (a click on www.example.com is tracked on checkout.example.com).

Alternative Integration Methods

Image pixel

For simple tracking without JavaScript:

<img src="https://delivery.wortise.com/log/conversion?wclid=CLICK_ID&type=purchase&value=9.99"
     width="1" height="1" style="display:none" />

Replace CLICK_ID with the wclid value from the URL.

Server-to-server (S2S)

Your backend can call the conversion endpoint directly:

GET https://delivery.wortise.com/log/conversion?wclid=CLICK_ID&type=purchase&value=9.99
