Conversion optimization or conversion rate optimization (CRO) could be the method of optimizing and increasing the rate of visitants to the website who undertake some wanted action like filling out a form, buying something, or perhaps agreeing to become a customer, among other things. The entire CRO cycle deals with developing a clear understanding of exactly how a visitor moves into your site, what actions they take, and what roadblocks they face that block them from performing the desired action.
