A/B testing is the process of setting up two or more styles for a page, for the same piece of content. For example, let's say you had a page where you sold blue widgets and you wanted to try using a blue button versus a red button to buy the widget. What you can do is A/B test the two types of buttons against each other.
How would you handle it? That is the question asked in a WebmasterWorld thread. Honestly, I am not sure what the "best" method to handle this is. So please join the thread or comment here.
