Google has released a new Website Optimizer Experiment Management API. This means developers can utilize Website Optimizer for their own applications and experiments.

Website Optimizer is a tool from Google that allows users to perform simple A/B and multivariate testing on websites to see what works and what doesn’t. WebProNews discussed the tool at length earlier this year. Here is a webinar video that will familiarize you with it as well:

"Website Optimizer handles splitting a website’s traffic, serving different variations, and crunching the numbers to find statistical significance," Google says. "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."

The API is an extension of the Google Analytics API, and is part of Google Analytics Labs. Being a labs feature means that it may not be perfect, and users may experience some bugs.

Google says that developers should look at the Google Analytics Data API Protocol document for general information about the GA feeds. The sections on Quota Policy, Audience, Getting Started, and Authentication are relevant to the Website Optimizer API.
