If you have a Wix account with a custom, connected domain - you can install Gist on your Wix website.

Gist can be installed on websites built with Wix via their "Tracking Tools & Analytics". It allows Wix users to embed third-party tracking code to their site.

NOTE: Connecting Gist will only work for sites on Wix with connected domains.

Here are the steps, as told by the Wix reference article:

To add your custom code to your site:

  1. Go to Settings in your site's dashboard.
  2. Click the Tracking & Analytics tab under Advanced Settings.

  1. Click + New Tool and select Custom from the dropdown. 
  2. Set up your custom code:
    1. Enter your custom code.
    2. Select the relevant domain.
      Note: This option will appear only if you have multiple domains.
    3. Enter a name for your custom code. 
    4. Add Code to Pages: Select which pages to add your code to:
      • All Pages: Click the dropdown to select an option:
        • Load code once.
        • Load code on each new page. Click here to learn more about this option. 
      • Choose specific pages: Begin typing the name of the relevant pages and then click the checkbox next to the relevant page. 
    5. Place Code in: Select where the code snippet should be placed in your site's code:
      • Head
      • Body - start
      • Body - end
        We recommend choosing Head. However, Gist will work even if you select any of the other two options.
  3. Click Apply.
