A/b Testing: The Most Powerful Way To Turn Clicks Into Customers

A/B Testing outlines a simple way to test several different versions of a web page with live traffic, and then measure the effect each version has on visitors. Using A/B testing you can determine the most effective way to increase conversion rate—the rate at which visitors convert into customers. The average conversion rate across the web is only 2%. That means 98% of visitors to most websites don't end up converting. Using A/B testing, companies can improve the effectiveness of their marketing and user experience and in doing so can sometimes double or triple their conversion rates.

In the past, marketing teams were dependent on IT and engineering to implement A/B tests, and that proved to be a costly bottleneck. Today, the market for A/B testing is growing very fast, in no small part due to this transition from IT to marketing.

DAN SIROKER is the cofounder and CEO of Optimizely. The inspiration for Optimizely came from Dan's experience as the Director of Analytics for the 2008 Obama Presidential campaign. Optimizely is the product Dan wishes he had back then to make it easy for anybody to do A/B testing. In 2012, Forbes named Dan one of the Top 30 under 30 in Technology. Dan was formerly a product manager for Google Chrome and AdWords.

PETE KOOMEN is the co-founder and President of Optimizely. After earning his MS in computer science from the University of Illinois at Urbana-Champaign, Pete joined Google as a product manager where he helped launch and grow Google App Engine to more than 150,000 developers. In 2009, Pete teamed up with Dan to start their first company, CarrotSticks, an online math game for kids. Less than a year later, Pete and Dan created Optimizely during the Y Combinator winter 2010 class. In between mountain climbing adventures, Pete runs product, engineering, and design at Optimizely.
