Honestly one thing that helps me save some time is remembering that the majority of articles online are going to be scanned by people, not read in-depth. This is especially true of
SEO articles. There is no need for it to be perfect as far as phrasing, as I'm not writing a poem or a book. I make sure each article has good points, correct grammar, and includes the necessary keywords, and that's it. I can usually write 2-3 an hour. It also helps to write what you know. I love writing the pregnancy/getting pregnant articles at WG, for example, because I'm experiencing all that now so I do not even have to research. Plus, it's interesting to me. It definitely takes some practice, but you will get there!
