Today Google launched a publisher-oriented service called Google Related Links. By adding a few lines of code, webmasters can display relevant links, searches and news to their visitors. Information is displayed in the form of a text box with three tabs, one for each type of content. Just like Google AdSense, Related Links shows information based on the content on the page the code is placed on. Google Related Links are fully customizable to blend into an existing website as much as possible. As of now, publishers that display Google Related Links are not being paid, but there is a possibility of this changing in the near future.
So far there appears to be no real incentive for webmasters to place Related Links on their websites. It offers very little value for most websites and unless publishers wind up getting paid for displaying it, I don’t see it becoming too popular.
