Google has simplified their home page getting rid of the ugly black menu strip that used to sit at the top of the screen and replaced it with a more attractive slimmed down version.
What does this redesign mean for search and SEO? The tabs Google left on the homepage are the Google+ (renamed +You), Gmail and Images search. Behind the apps icon are a second +You tab, a search tab, Youtube, Maps, Google Play, News, Gmail, Drive and Calendar. +You has ten of millions fewer users than the other Google products, yet it is the first tab on the redesign. This shows the importance Google is putting on +You and competing with FaceBook for a share of the social marketplace.
Google feels threatened by Facebook and as Google looks into the future it see social as a major area of growth and competition. This redesign further emphasizes the importance of +You in SEO.
