Some people will argue that you shouldn't start a blog in a niche that isn't too popular. For example, if you want to write about something like crocheting or playing a specialized instrument, understand that the appeal of the blog can only be as large as the total global audience in your prospective language. Some things simply don't have a large audience.
Keep in mind that making money from your blog takes time. After all, there is a reason that learning how to make money from a blog is the last step in my guide. You need to make sure you have followed all the previous steps perfectly in order to give yourself the best chance of earning a substantial income from blogging. This will not happen overnight, but most bloggers find that the work itself is rewarding enough to continue on the journey.
What is your ”spin”? To set yourself apart from the crowd, you’ll need to do something different and interesting with your content. Will you have an interactive focus? Focus on bizarre day-to-day news events instead of celebrity dish? Whatever you choose to blog about, make sure that you have ways to approach it creatively and that you can consistently offer new, exciting content.
Thankfully, you needn’t be tech savvy to start a blog (we certainly aren’t). You don’t need to know how to code or design to build your blog (we still don’t). You don’t need much money to create a blog (you can get a free domain and host your site for just a few bucks a month). And you don’t need to spend a ton of time setting up your blog, either (you can set up your blog in less than an hour).
The next step in building a blog that will actually make you money somewhere down the road is to purchase a domain name. If you’ve decided what you’ll blog about, then you need to find a domain name that’s going to be harmonious with that. Pick a name that’s short enough to be easily remembered, but also keyword-rich enough to be applicable to your content.
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.
You'll want to track these influencers down and start sharing their content and becoming active in their communities to start gaining their attention. You may have luck by simply messaging them out of the blue, but it's not likely. Once you think you have their attention, you can try to reach out to them by asking them to promote something on social media, publish your post on their blog or link to a post of yours on their site.
PS: my answer to this question is always… “the better question is… how can my blog help me build a profitable business?” Most of the profits from blogging are not made on your blog, but that’s okay. I don’t believe blogging about making money per se, but about branding yourself and positioning yourself within your niche market as an authority and leader. Once that is established, there are so many ways to move people into your money making enterprises. Email marketing, as you pointed out, is one of the best ways to do this. Sending people to your membership sites, services, info products and coaching programs are all great things to route people into as well.
