ClickZ took some time at the Share13 conference on Aug. 23 to speak with Jim Yu, CEO of BrightEdge, about the SEO profession, the future of mobile, and why content is so important. "Six years ago when we started I talked a little bit about going up and down the valley and there was only a handful of people focused on earned media and SEO and now there are over a million people six years later. And I think a lot of that is because of the business impact that earned media and SEO are able to drive…That's elevating the community around search and really driving innovation," said Yu.
