​

Using a Tag Manager to insert the Mida tracking code on a page is not the best option because the script loads after the page has finished loading, which causes delay until the experiment changes are applied.

​

Users may experience a flickering effect, seeing the original page before the changes to the variation content are displayed.

​

We do not recommend using any Tag Manager (e.g., Google Tag Manager, Tealium) to insert the primary tracking code on a page.

​

However, if you don't have easy access to your site's source code to add the Mida script, you can use Google Tag Manager (GTM) to inject it.

​

If you experience a flickering effect after GTM installation, adding Mida’s anti-flickering script to the HEAD section of your experiment page can help improve user experience.
