Conversion rate optimization through evolutionary computation [PDF]

open access: yesProceedings of the Genetic and Evolutionary Computation Conference, 2017
Conversion optimization means designing a web interface so that as many users as possible take a desired action on it, such as register or purchase. Such design is usually done by hand, testing one change at a time through A/B testing, or a limited number of combinations through multivariate testing, making it possible to evaluate only a small fraction
