The latest ‘MarketingExperiments’ blog post is titled “Marketing Experiment: Learn from our split testing mistakes”.

Daniel Burstein says, “We recently held a subject line experiment contest with the fine folks at Copyblogger. On Tuesday, we published the results of this experiment on the MarketingExperiments Blog to hopefully help you improve your own A/B testing.

While Tuesday’s post was exciting, today’s post is a word of caution.

Essentially, I’ll discuss what we (intentionally) did wrong so you can learn from our mistakes. By running a split test publicly for teaching purposes, we necessarily introduced some validity threats”.
