Quality content is content that people can engage with and find useful. Your content should help readers and bring them value. Your blog needs to have interesting, helpful content that people would be willing to recommend or share with their friends. The format, structure, layout (and, of course, the writing itself) will all determine the quality of your blog.
Your newsletter is all yours. Unlike social media sites, your newsletter and email subscribers are all yours, and you have their undivided attention. You don't have to worry about algorithms not displaying your content to readers, and this is because they are your email subscribers. You aren't fighting with anyone else to have them see your content.
If you are using a free blog hosting service instead of your own domain name, you must provide high quality content with a limited number of relevant links or risk being shut down. If you are only interested in writing short, quick product reviews in order to earn money, you will need to host your own blog. Be warned that low-content, high-link blogs are a less reliable, though lower effort, way to earn money.
My understanding is that you have to subscribe/pay for the business version of Word Press in order to use any of the monetizing functions. I think you should clearly state this in this article at the beginning. I think there is a degree of bait and switch here if people are just signing up for the free subscription and then finding out they have to pay for a subscription to make money. I am ok with that, it just needs to be stated up front everywhere.
Sometimes I think we just need permission to do the things we love without having to make a living at it. So I'm giving you permission. I'm telling you it's fine for you to have a blog that gives you an outlet for your creativity, allows you to talk about things that are important to you and lets you stay connected to friends and family. You don't have to try to monetize your joy.
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.
