A/B Testing Simplified

Optimizely makes A/B testing second nature. Forget about rounding up technical resources or extended meetings about what test to run. Design experiments visually, define goals with a single click, and click go - Optimizely takes care of everything else, from hosting your designs all the way to the results page.

Data you can put to work

Data You Can Put To Work Right Away

Whether you're running a simple A/B test, or a multi-goal, multi-page monster, Optimizely automatically analyzes the data and transforms it into a crystal clear report. Have something to show for your testing effort - a solid roadmap of exactly how your redesigns will improve conversion rates. Even revenue tracking is supported right out of the box, so top earning variations can shine.

Goal tracking

Powerful Goal Tracking Makes Anything A Metric

Optimizely's dynamic test pages transform any element or user interaction into a source of data. Whether you are interested in overall engagement, bounce rate, page views, sign-ups, or click goals, or you're deep in the optimization cycle, working on multi-page funnel conversions or form variations, Optimizely is the AB testing tool that gives you the insight you're after.
