Introducing the Website Optimizer Experiment Management API

Today at the eMetrics conference in Washington DC we announced the new Website Optimizer Experiment Management API. The API allows for the creation and management of experiments outside of the Website Optimizer interface.

If you're not familiar with Google Website Optimizer, it's a free tool for running A/B and multivariate experiments on a website. Website Optimizer handles splitting a website's traffic, serving different variations, and crunching the numbers to find statistical significance.

Creating experiments with Website Optimizer usually involves a lot of back and forth between your website and the Website Optimizer interface. Using the API, you can integrate Website Optimizer into your platform. In short, you can create and launch experiments from whatever tool you use to edit your site.

You'll find more about the GWO API on its Google Code site: http://code.google.com/apis/analytics/docs/gwo/.

You can also join the Website Optimizer engineers for a webinar on the Website Optimizer Experiment Management API. The webinar will be held on October 28th at 10AM PDT. During the webinar, Website Optimizer engineers will walk you through how the API works. Additionally, two platforms that have already integrated using the API will demonstrate their integrations.

You need to register for the webinar, which you can do here. We'll record the webinar as well so you can reference it later.

We're very excited about the Website Optimizer API and what it means for website testing. Let us know your thoughts in the comments.


  1. Optimiser is a great tool and if it can be displayed on a custom Dashboard with the use of API's, Brilliant!!!

  2. Very exciting to see an API for Optimizer.

    I'd welcome some more general documentation on terminology such as an Experiment, Section and Variation. It can be a little confusing on first reading.

    And I'm also wondering how many HTTP requests will be required to view all variations for a single experiment - this does seem to max out the GData style of related Link elements, with a seperate Feed/Entry for each entity.

    I'd also quite like Google Analytics, and other Google Apps, to provide documented predictable/REST type URLs to their public interface ie. allow link direct to a report within Google Analytics from a CMS system, where using the Data Export API may not be appropriate.

  3. have not being on this site for while but i like this this one,

  4. is it possible to have a video version of the webminar? I think everybody will want to watch that...
