Conversion rate optimisation (CRO or Conversion Optimisation) is the process of increasing the percentage of conversions from a website or mobile app. Conversion rate optimisation typically involves generating ideas for elements on your site or app that can be improved and then validating those hypotheses through A/B testing and multivariate testing.
