SEO in 2012 focused on mobile search, personalized search, and social search becoming more prominent. Mobile searches accounted for 41% of Super Bowl searches and 59% of holiday searches. Personalized search results were tailored based on individual user profiles and search history. Social signals from networks like Google+ and sharing became important ranking factors as search results integrated more social content. While classic SEO still applied, the future emphasized a more unified, social experience across Google's products.
