A lot of successful websites depend on returning visitors to account for a major part of their traffic. Returning visitors are easier to convert into paying customers because the more often they return to a site, the more trust they have in that site. The credibility issue just melts away. Hence, keep your visitors coming back to your site with the following methods:
Start a forum, chatroom or shoutbox: When you start a forum, chatroom or shoutbox, you are providing your visitors a place to voice their opinions and interact with their peers — all of them are visitors of your site. As conversations build up, a sense of community will also follow and your visitors will come back to your site almost religiously every day.
Start a web log (blog): Keep an online journal, or more commonly known as a blog, on your site and keep it updated with latest news about yourself. Human beings are curious creatures and they will keep their eyes glued to the monitor if you post fresh news frequently. You will also build up your credibility as you are proving to them that there is also a real life person behind the website.
Conducting surveys or investigations: Polls and surveys are other forms of interaction that you should really consider adding to your site. They provide a quick way for visitors to express their opinions and get involved in your website. Be sure to publish opinion polls or surveys that are closely related to the target market your website to keep them interested to learn about the results.
Keep puzzles, games and contests: Imagine how many employees at offices delayed at work every day, and will be able to measure how many people keep visiting your site if they provide a very interesting way of entertainment or addictive. You can also hold contests for the award-winning high score to keep people continually trying to win the prize.
Updated frequently with fresh content: Update your site frequently with fresh content so that every time your visitors return, they will have something to read on your site. This is the best known and most effective way to attract visitors, but also the least paid a result of the laziness of webmasters. Nobody want to browse a site that looks even more than ten years, so keep your site updated with new bite!
