Google released Related Links, a feature that lets you add to your site dynamic links to related news, searches, and pages.
Google Related Links look similar to AdSense ads, and are available in four formats:leaderboard, banner, small and large rectangle that can be customized.
If Google can't find relevant links related to your site, you'll see a Google search box.
It's important to be aware that Google Related Links aren't tied with a AdSense account and you don't receive any money for clicks.
This feature was spotted on a Googler's blog last month.
