ClickTale, a provider of in-page analytics, and Optimizely, a global website optimization platform, have announced a partnership to integrate their complementary services into a comprehensive offering for businesses. Optimizely’s A/B testing platform, combined with ClickTale’s anonymous user session playback, heatmaps, conversion funnels and form analytics, will enable businesses to pinpoint the most impactful sections of their websites, test different versions and analyze how the changes affect customer behavior.

A/B testing is a popular method used by marketers to create different versions of their web pages and test the effect of those changes on website performance. As all marketers would agree, knowing which aspects to test has always been a challenge. Many companies still only guess which elements on their pages influence customer behavior. The integration of ClickTale and Optimizely is meant to eliminate this guesswork by providing businesses with a behind-the-scenes look at visitors’ precise online behaviors.

“By partnering with companies like Optimizely, we are able to offer our customers a complete cycle of optimization, from observing user behavior through testing a hypothesis to understanding the results of the test,” said Dr. Tal Schwartz, chairman and CEO, ClickTale. “ClickTale uncovers the insights of what to test, Optimizely provides the tools for the test, and ClickTale facilitates the understanding of the behavioral reasons behind why one version of the test was more successful.”

ClickTale’s flagship product, ClickTale Core, allows businesses to visualize online customer behavior by capturing their every mouse move, click, hover and scroll. Optimizely offers a simple editor for creating A/B tests. Both services require one line of code added to each page being tested.
