This snippet allows a content users in OU Campus to add different variations of content to test. On page load, the javascript (via jQuery) chooses a variation at random to display to the user. If Google Analytics is loaded on the page it will set custom dimension 1 to the variation number.
This project is very much a work in progress and will probably change as time goes on. Don't trust this will production data yet, this is still in development.
Create a custom dimension in Google Analytics. Currently the script is hardcoded to dimension 1.
Publish js/ab-test.js to your webserver. Import xsl/snippet-abtest.xsl into an existing stylesheet and change link to ab-test.js to go to your published version of the file. Add snippet-abtest.html to your sinppets directory (probably /_resources/ou/snippets) and register the snippet with OU Campus.
