For Optimizely servers to supply personalized content to your site, you need to include a link to the Optimizely Recommendations JavaScript integration code in all pages of your UAT and live websites.

When you first configure your site to use JSON, include the following tag on all pages of your UAT site (including [Checkout page](🔗) and [Order page](🔗) :

## UAT domains

### Standalone clients

### Native clients

📘

Note

Ensure that the UAT script is placed on your UAT site.

## Production domains

• United Kingdom cluster – _\<sitename>.peerius.com _

• Sweden cluster – _\<sitename>.peerius.episerver.net_

• United States West cluster – _\<sitename>.uswe01.productrecs.episerver.net_

You need to add the production version of the script to your live site in the same way:

The `clientname` element is provided by Optimizely.

📘

Note

Do not add the above script inside <div> tags, because it may cause Internet Explorer to crash.

Position this tag just above the </body> tag, before any Google Analytics scripts or slow-loading social media tags.
