Universal search: [ May 2007 google algorithm update ]
Before universal search, google displayed webpages with text content seperately, images seperately and so on.. It was framed that you gotta search everything seperately. With Universal search google got the right junction for employing most of its services such as youtube, maps, images, local, books etc.. on the search engine results page [SERP]. The previous SERP was officially declared dead (10-listing) and the new SERP took over!
The Universal search not just limited itself to the google platform. Videos, images, documents from other websites too showed up in Universal Search Engine Result page.
