Hi, e-commerce owners, What techniques or services do you use to engage visitors on your e-commerce sites? We at OllyBee.com are currently building a gamification app to increase engagement, so we are also interested to know what other tools or techniques you use to keep the high engagement. Thanks in advance. P.S. In a nutshell, we're developing game-driven promotion like hide-and-seek game (I hope you played at it when you were a child). You can hide graphical objects on your website and suggest visitors to seek them. If a user finds graphical objects he can get a reward for this (for example, discount on your products).
