Write down every topic that you are knowledgeable or passionate about. You'll have a much easier time making money from a blog you are interested in, rather than trying to write content you don't like because you think it will make money. Some examples are hobbies that you enjoy, your career, or some specific and miscellaneous knowledge that you have.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
