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.
Thanks Donna for taking the time to write this excellent comment. I agree with you 100%. A blog can give you an income from offline sources and is a great way of diversifying into different areas, but again it also depends on the niche you find yourself in. I always say to people to not be too reliant on one source of traffic or one source of income, because they can vanish pretty quickly.
To all the bloggers out there…STOP sucking up to the very small, elite and narcissistic group of self-proclaimed influencers out there. If you all stop treating them like they’re special, they will not longer by special and therefore some of us who aren’t in there secret society will be seen as knowing what we’re talking about too! This isn’t High School, grow up and read someone else’s blog already!
