You might have noticed that Google has a new look and feel when displaying your search results beginning in May 2010.  Rather than just displaying the top ranked sites for your search term, they now display in the left hand column one click search results for video, blogs, news, updates, books, images, discussion, and more to come.

Google has improved the user interface to shorten the number of “clicks” it takes to get to the type, and freshness of content that best serves the “searcher”.   They are also implementing their major overhaul of their algorithm code named Caffeine, so expect some fluctuations in your search engine placement.
