Remember, the more points you have the higher your site will be listed. Higher sites receive more hits which will bring you even MORE points. Maintain a quality web site for repeated visitors. If you have repeated visitors, each time they return to your site they will be building up your score. With a higher score, you will be ranked higher in the listing.
Higher ranks bring new and more visitors.
If your site is good, those new visitors will also begin returning. This process will drive your site to the top. In short, the goal is to maintain a site people will want to return to. No referrals from your site were received in a 24 hour period. Add a popup window.
