Using a new Google search feature, “if you click on a search result for a forum and then go back to the search results page, Google adds a link ‘get more discussion results’, report SEL. Same feature is available if you click on "show options" and select "discussions", but it's more difficult to find. Google says “This’s indeed a new feature we started testing. It’s meant to give users who click on a result, visit a web page, then click back, the opportunity to discover more information of that same type. Think of it as us showing the user relevant search options when they click back on a result that belongs to one of the search options categories such as…’Discussions’.” When you click on a search result, Google tracks the click and uses it to adjust the order of search results. Surf Canyon is an extension that customizes your search results based on the results you've selected and shows recommendations when you click on a search result.
