Accredited online SEO Content Writing CourseWatch
As far as I know, there is no professional nationally or internationally recognised institution for content writing. There are good courses out there for content writing, but none that would lend to the same credibility as something you can use anywhere in the world. The field of content writing is also ever changing, so even if you do go on a university accredited course, the online environment may end up changing once you graduate.
The sort of content writing courses that I have seen mentioned and vouched for by professionals (with likely biases) are:
- Clickminded - I would personally recommend for digital marketing in general
- Content Marketing Institute
- MOZ - highly recommended for SEO
- American marketing Association
- Digital Marketer
- Canadian Marketing Association
- SEO Roadmap - SEO specifically
There are others courses by a number of non-Ivy League American universities (because they can virtually create courses on anything), but they will be accredited.
I'm currently looking into CIM's diplomas and awards, which can be the equivalent of degrees, but a lot cheaper and more professionally recognised in marketing. I don't think they have much content on SEO or content marketing though, and they don't particularly help you if you want to go into music journalism.
As far as I know, there isn't anything overly complicated or novel in content marketing or SEO in the courses. A lot of it will be common sense, but there might be a few technical things you will need to be aware of, especially in SEO which is very different from content writing.
