You have done all your marketing right and the customers are flocking to your site, yet, no one is signing up. What could be the problem? Why aren’t customers converting? That is where A/B testing comes in. Instead of trying to guess why your customers are not converting, use A/B testing to get data on what makes the customer convert. A/B testing is a method used by many businesses to get feedback on what version of their site or email campaigns converts more.
