Say for example you have a site on German Shepherds that contains several articles that are ranked in google for their keywords, but you also want to get traffic from Pinterest. And lets also say that everything that can be said on the topic of German Shepherds has already been covered on my site. So what can you do to get traffic from Pinterest? Just create a tonne of new images linking to my already existing articles? Or would you have to keep on churning out new articles on your site for all eternity to keep the traffic coming in?
