FREE Writers Write, a school in South Africa, has compiled a collection of its articles to teach BLOGGING at https://www.writerswrite.co.za/everything-you-need-to-know-about-blogging/
I strongly encourage you to read all the posts in the links. Especially before starting blogging. If you’ve already began, this course will help you improve your writing and blogging in many aspects.
Amanda Patterson, the instructor, wears several hats as a writer, blogger and she is everything all at once.
Rating: 5/5 stars.
