A/B Testing: Turn Hunches into Results
- Subject lines. Send your control email to one group, but swap in a different subject line on your challenger email.
- Headlines. Leave everything the same between control and challenger, except for the text of the headline.
- Body copy. Here’s where you put your copywriter to work. If your control has long copy, test shorter copy in your challenger (and vice versa). Or, if your control takes a gentle approach, test a punchy, in-your-face challenger.
- Calls-to-action. Reword your call-to-action in your challenger. Note that this does not mean you change the offer itself—only the way you drive people towards it.
- Single design elements. Let your graphic team get creative. Swap in a new banner, Download button, link color, or sidebar. Again—make only one change at a time!
- Aprimo Marketing Studio has campaign management tools to randomly split your groups for A/B testing of outbound messages. In addition you can use criteria to dynamically serve up different content in emails and microsites and monitor results through your dashboard to focus on the best results and learn for future efforts.
- Google Website Optimizer is a free Google service that lets you present different content and design options to your visitors. Google tracks the conversion results.
- SiteSpect lets you run not only A/B testing, but also multivariate testing in which you test many changes at the same time.
- Omniture Test&Target is an interface for designing and executing your tests.
- Webtrends Optimize provides a unified testing and targeting platform.
- Vertster speeds up the process of performing multivariate testing, when you’re ready to go there.
Got a gut feeling about what works and what doesn’t? Use testing to check those hunches and back them up with measurable results. You can be sure your top competitors are already doing it. So, move A/B testing to your front burner today—and make it an ongoing part of your efforts.
