Aaron Wall noticed Google is testing a new location for “related” search results. This time, the location appears to be directly under each individual search result’s URL. Here is a screen shot of it in action, from Aaron’s blog:
Aaron said he was able to see it by searching for link building while using the Opera browser.
It is also interesting to speculate how Google determines to show which related phrases for each result. If you notice, Aaron’s seobook.com result shows a related phrase for get more links and if you search in Google for that, seobook.com does rank in the number one position for that search phrase.
