Yes...but... There will be a learning curve. You don't have to be a technical wizard who enjoys coding sites in your spare time. But you do need to understand the SEO copywriting basics. Otherwise, you are doing your clients a huge disservice.  Not understanding SEO best practices means you'll miss important opportunities (or make mistakes) that can cost your client money. (Fortunately, SEO copywriting skills can be picked up fairly quickly.) You'll also need to learn the basic copywriting ropes. If you want to help your clients succeed (and that means helping them make sales,) it's crucial that you understand how to create conversion-oriented copy. It will help you write better Web pages, improve your email campaigns - and even help you drive more traffic to your site.
