I’ve been an SEO copywriter since mid-2007. When I first entered the field, I knew absolutely nothing about it beyond what SEO stood for. I didn’t know what a duplicate content penalty was (or more correctly, was not); about black hat tactics; keyword strategies; etc.
And I knew nothing about the foundation of SEO – internet marketing itself. And to my great surprise, neither did a lot of my clients.
The reality of internet marketing that’s pertinent here is twofold: (i) it is a rapidly developing medium that very few online marketers really understand; and (ii) you will have to educate your clients to sell more.
