From Entrepreneur magazine's coaches corner:
"We reached out to a team of SEO experts to break down how smarter content can showcase your company’s assets, boost your content quality and eventually pull your site to the top of users’ search results. Here’s what they suggest."
That sentence from Jason DeMers summarizes 3 years of Google's algorithm changes: "whereas a few years ago, it was defined by manipulative tactics, SEO in 2014 is largely defined by quality content publication."
This article captures well what the new SEO is all about: showcasing your expertise through quality content on a consistent basis.
