All the site owners want traffic to increase sales and profit. However, the need of active traffic is rarely desired. The active traffic is the visitor who communicates on the site by leaving comments, giving votes, reading, watching or listening to the posted content, video or advice. My two sites are ideally based on user interaction. The first one is OpenBlog for people to subscribe to article, whereas another one is a help-in-relationship site. I need to bring in more active traffic for both the site. Please recommend some method to ease my burden. Thank you very much in advance.
