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.
Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
