Take yourself now. How long have you already been chatting to Charlie here to the right? Well, it's not just you. It's a proven fact visitors spend more time on websites when there are interactive characters around to talk to. And when they're done talking, they are more apt to further explore your site for other cool features, meanwhile looking at your products and services with a renewed interest. Even when they're gone, they will likely remember your site and come back at steady intervals to hear what's cooking.
