With the launch of Google+ and Google’s introduction of personalized social search results, have come new challenges and opportunities for Search Engine Optimization.
Before Google+ was Google’s +1 button. Now, fully integrated into Google+, this feature influences search results and can be used to help increase a pages rank in a Google search.
In recent months, Google has rolled out social searching, which relies heavily on Google+ to give users personalized results. Other social networks play a role in this, but Google+ is heavily favored by Google in this process.
