Most bloggers actually welcome the advance to create great content for their platform. So you shouldn’t be shy in at least trying. There’s no harm in trying. If you succeed, then it will be a big win. If not, continue to network and add value on your own, and eventually, as you build it, they will most certainly come. Just don’t expect it to happen quickly or easily.
If your answer was the former, you’re wasting your time. In fact, if you’re not starting a blog because you’re inherently passionate about whatever it is you’re blogging about, it truly is a lost cause. Why? Because building a blog to any semblance of an audience is an astronomical feat. I don’t tell you that to scare you. Only to prepare you for what’s to come.
However, aside from that, you can always opt to generate small amounts of cash flow by doing other things such as creating articles that will lead people to courses or audiobooks that you've developed, or building out video tutorials that will ultimately sell some big package or system that will help to teach people whatever it is that you're really good it.
Selling private ads can come in the form of banners, buttons, or links. You can even make money writing sponsored posts where you write about or give a review of an advertiser’s product or service. Another option is to write an underwritten post or series, which is where you can write about any topic, but the advertiser pays for a “Brought to you by” mention in the content.
