Facebook experienced the largest percentage growth of writers names appearing on page 1, increasing by 10 to 62 percent, but only 9 percent of all Page 1 appearances were in high visibility (1-3) ranking positions.
While Twitter was left with not much room for growth with 91 percent of writers appearing on Page 1, by June of 2012, Twitter appeared on Page 1 of the SERPs for nearly all of our writers (95 percent).

In the six months between our analyses, Twitter had the biggest growth in Page 1 appearances in high ranking positions. Put another way, Twitter is now almost always on Page 1 and at the top of Page 1 when Googling the top tech writers in the world.
When it came to changes in Google+ visibility, Google’s social network grew by the smallest percentage of all networks, increasing by 3 to 36 percent.
