How to block cookies and trackers with JavaScript rewrite

This guide explains you how to block cookies and plugins with Secure Privacy using Javascript rewrite.

To block cookies and trackers you need to change the attributes of the script tags on your website. Follow these steps to change the attributes.

  1. Apply the attribute sp-consent="PLUGIN NAME" to the script/image tags on your website. Depending on where you have installed the plugins, this may be inside a module, plugin or directly on your website. Make sure that you write the exact plugin name, which appears on your Scan Report.
  2. On script tags change the attribute 'type' from 'text/javascript' to 'text/plain'.
  3. If you are using a pixel tracker (image trackers), then change the attribute “src” from “src” to “data-src”.

<script type="text/javascript"> code…

​<script type="text/plain" sp-consent="Google Analytics"> code…
