Add a Multivariate Project

Multivariate testing rotates HTML page elements to determine what combination creates the most effective page display. It is best used to determine what content or creative changes result in the greatest number of conversions.

  1. From the navigation menu, click Laboratory.
  2. Click New Project.
  3. Enter a name, description, and select Multivariate as the project type. Click Next.
  4. Click Browse and select a project page that you added earlier. Or, click New and add a new page for this project.
    Note: A page can be used by one project at a time.
  5. Determine the percentage of page traffic (Traffic Throttling) to be presented with testing or targeting content. Any remaining traffic is presented with default content. It is often useful to lower throttling on high traffic pages in order to limit consumption of Optimize Events. To change the current value, click the percentage and enter or select a new number. 0.1 is the minimum. Traffic throttling can be changed at any time.
    Note: By default, Optimize reevaluates returning visitors to the test or target page as new visitors and uses the current throttling percentage to determines what type of content to present. To present returning visitors with the same content they viewed in previous visits, clear the Reset project throttling cookie check box.
  6. (optional) Click Project Alias and change the generated alias. The project alias is used to uniquely identify a project. For coding purposes, it is assigned to a project before you select a project page; however, you can change the alias here.
  7. Add one factor for each HTML element that you want to test.
    1. Click New Factor and enter a factor name and description. Enter a friendly factor name as it will appear in your test results.
    2. Enter the element ID that identifies the factor on the test page. The element ID must match the ID of the HTML element in the web page you want to test. The ID must be unique within the test, begin with a letter (A-Za-z) and may be followed by any number of letters, digits (0-9), hyphens "-", underscores "_", colons ":", and periods ".".
    3. Select Script Only (Advanced) if the factor will be comprised of JavaScript only. All content for script-only factors must be script only as well.
  8. Select the mathematical method you want to use to present experiments to page visitors.
    Note: Testing methodology only applies to multivariate project types with three or more factors.
    • Fractional Factorial displays a subset of all factor combinations (experiments). This method uses predictive analytics to provide results faster than full factorial tests.
    • Full Factorial displays all possible factor combinations (experiments) and can take longer than the fractional method.
  9. Click Add a Conversion Event and select the type of conversion event you want to associate with this project. There are four event types: On Page Load, On Click, Time On Page, and Custom.
  10. Enter an event name and description for the conversion. You can also change the conversion event ID.
  11. Click Browse and select an Optimize test page that you added earlier. Or, click New and add a new test page for this conversion.
  12. For On Click events:
    1. Enter the element ID that identifies the HTML element that will trigger a conversion when clicked by a visitor. The element ID must match the ID of the HTML element in the web page you want to test.
    2. (optional) Click + to add another element ID. When you add multiple HTML elements, each one counts toward the conversion event when clicked. Click - to remove an element from the conversion event.
  13. For Time On Page events:
    1. Enter the minimum visit time duration, in seconds, that must be exceeded in order to trigger the conversion event.
  14. For Custom events:
    1. Enter the script event name that will trigger the conversion event. All W3C standard JavaScript events are supported. User-created, custom browser events are also allowed.
    2. Enter the element ID of the HTML element that will trigger a conversion when clicked by a visitor.
    3. (optional) Click the + button to add another script event and element ID pair to the conversion event. You add multiple script event/element pairs when you need more than one type of script event to suit different HTML elements. A conversion is recorded each time a script event is triggered by the visitor and counts toward the conversion event. Click - to remove a script event/element pair from the conversion event.
    4. Click Save.
  15. Click Finish.
