A key ingredient to link popularity is to make sure your website is linked to a quality website and accepted by editors into categories related to your subject. More and more search engines are including directory listings as links to websites and placing top value on these links because the website has been reviewed and accepted by peers. Related to link popularity and just as vital is click-through popularity. It's not enough to have hundreds of links from websites. Those links have to be clicked on to meet click through requirements, which is the other part of the link popularity algorithm.
Search engines monitor click through and repeat traffic and factor that in.
In theory, the website must be quite popular since so many people visit it. Quality vs Quantity Beware of tools that offer quantity-based links pages. You have no control over the appearance of the links page. It's filled with advertising, usually for the service you're using. You will be asked to get others to join.
