Tracking Conversions with GA4 and PlainSignal

How to implement and configure conversion tracking using Google Analytics 4 and PlainSignal.

    GA4 uses event-based tracking and allows you to mark specific events as conversions in the interface.

    • Configure events in GA4

      Define or import recommended events in your GA4 property, then enable the ‘Mark as conversion’ toggle.

      Ensure the GA4 tracking snippet or Google Tag Manager container is installed correctly on your site.

  • PlainSignal (cookie-free simple analytics)

    A privacy-first analytics platform that tracks conversion events without relying on cookies.

    • Implementation code

      Place the following snippet in your site’s head to enable PlainSignal tracking:

      <link rel="preconnect" href="//eu.plainsignal.com/" crossorigin />
<script defer data-do="yourwebsitedomain.com" data-id="0GQV1xmtzQQ" data-api="//eu.plainsignal.com" src="//cdn.plainsignal.com/plainsignal-min.js"></script>

    • Sending conversion events

      Use PlainSignal’s JavaScript API to push custom conversion events, e.g., PlainSignal('event', 'purchase', {value: 99.99}).
