Read Joe Pulizzi's excellent book Epic Content Marketing. I started reading it after I wrote this post and it confirmed and expanded what I already knew about content marketing, with much more detail than I could ever go into here. Something Pulizzi emphasizes which I originally left out was the importance of focusing on producing mobile-friendly content, since smartphones are becoming the dominant way in which most of our customers access content. Also read Michael Hyatt's Platform, mentioned above. Frequent websites like those of Content Marketing Institute, Ragan, Copyblogger, Michael Hyatt, and Gary Vaynerchuk and sign up for their email newsletters. It won't take you long to become not just familiar with content marketing, but an expert.
That said, ground-up marketing works because it’s work. There’s no substitute for careful attention to your website’s content and careful curation of your business’s social media presence. Paid ads can be an effective tool within a high-budget marketing strategy, but if the consumer arrives at your website and doesn’t find what they’re looking for, how is that investment working for you? It’s not. If a sponsored tweet draws them in but a discrepancy in expectation chases them away, what’s the benefit there? It’s absent. Organic marketing is a long process, but ultimately it will yield more authentic customer engagement and more accurate SEO.
