VWO (Visual Website Optimizer)

VWO offers both Asynchronous and Synchronous code that you can add to your web site. You can choose either one and simply need to change the <script tag.


Change the type and add the data-consent attribute so that it looks like this:

<script type="text/plain" data-consent="analytics">


Change your code from:

<!-- VWO One Smartcode (Replace <ACCOUNTID> with your VWO account id) -->
<script src="https://dev.visualwebsiteoptimizer.com/lib/<ACCOUNTID>.js"></script><br>


<!-- VWO One Smartcode (Replace <ACCOUNTID> with your VWO account id) -->
<script type="text/plain" data-consent="analytics" src="https://dev.visualwebsiteoptimizer.com/lib/<ACCOUNTID>.js"></script><br>

Flickering issue

Some of our users have experienced issues when implementing VWO with CookieHub causing the browser view to show a white page for a fraction of a second after all elements have been loaded and rendered. To avoid this add the following CSS code to your web site to make sure VWO can't change the opacity of the body element:

body {
  opacity: 1 !important;
  filter: none !important;
