Just saw your quote about content marketing.I would like to tell you that once upon a time in the land of Search Engine Optimization, a business could assemble a sub-par website full of carelessly written content, throw in a hefty helping of meta tags, craft a few links and they would enjoy instant search engine ranking. But those days have gone now.
