If you are planning to start a new website you need to think about the website layout and design. I had seen many sites which has got a good content but they are not able to present the data clearly to the user. If the user cannot find the information easily he will easily tend to go out from the site. So you need to be very careful in designing your website. The layout design, the color, the font and the placement of other things are very important. You need to place a very good header which the visitors can remember. You need to place buttons for email subscription and bookmarking. SO think for a while about your site design rather than just starting with a normal layout or theme.
