Normally when related queries are suggested after doing a search on Google, they appear at the bottom of the search results page (SERP). I noticed this weekend Google is testing the display of other Google categories as well as related search queries above the right side column ads. (Outlined in red)
The example above shows a link to Google Products. However, other keyword queries generate links to other Google search products: Google News, Scholar, Blogs, Books, Video, etc. I am only able to create these results on Firefox using Google, not via MSIE or Opera browsers.
What does this mean for search marketers? Not a whole lot. But if Google started using the top right screen real estate to start showing links to more information, it could present secondary promotion opportunities in the same way that OneBox results do.
