5 Helpful A/B Testing Sites

June 4, 2013

If you want to maximize your return on investment, you should conduct A/B tests on your marketing materials. In general, an A/B test (or split test) is when you test two different versions of a specific marketing tool against one another to see which performs better. For example, you might send two different versions of a postcard to small segments of your targeted mailing list. The postcard that yields the greatest response will then be sent to your entire mailing list, with (theoretically) predictable results. Once you have a winner, you continually test it against other versions before launching full scale campaigns. Most companies have a “control,” which is their standard and proven version; and they test it against “treatments,” which are different versions. If a treatment is proven to work better, it then becomes the control. In this manner, you can continually improve your marketing materials and, over time, generate greater response and increased profits. It’s important to keep in mind that your control and treatment versions do not have to be dramatically different. Minute details, such as the position of a call to action or your headline copy, are all that should be different between versions. If you change too much, it will be impossible to know why a specific variant works better than another. The goal of A/B testing is to eliminate the guesswork over time, so you can deploy winning marketing materials that yield excellent return on investment. The following websites will help you create better marketing materials by exploring A/B testing results; the lessons learned can be transferred between marketing materials. For example, if a specific type of headline works better for a landing page, that same headline might likewise perform better than other variants on a postcard. You can save a lot of time and learn from others’ work by studying the following five helpful A/B testing sites.
