Yesterday I stumbled upon this blog post http://www.nonlineblogging.com/blog/2010/2/11/dont-be-mr-average-why-averages-are-a-bad-bad-thing-in-digit.html and it’s right on. If you think about it, you can’t really improve conversion rates unless you start segmenting your traffic and identifying those under-performing segments. Sure it takes time but compare it to the investment you make in acquiring media and driving visitors to your website. Go the extra mile: segment your traffic, figure out which segments are not converting and target them with relevant and personalized  messages. Improving conversion rates for these segments is the only way to increase the average.
