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.
If you aren’t part of an ad network then you are constantly searching for new companies to advertise on your site. This one was always a pain in the ass for me. I wanted to spend time making my site better, but if I ignored selling my ad space then I wouldn’t have money to continue to make my site better. You can join an ad network, but that means you are giving up a percentage of the revenue. Work hard to only get 50% of the money? Bleh.
A blog is not a blog without content so once you’ve set your blog up you need to focus your attention upon creating useful content. What you choose to create will depend a little on the topic that you choose to write about (on that note, most successful bloggers have some focus to their blogging whether that be a niche or a demographic that they write for).
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.
