Affiliate marketing is my absolute favorite way to make money blogging. I love it because it can feel quite passive. You can create just one blog or social media post, which can potentially still earn you money years down the line. Now, you will have to maintain the post and keep generating traffic to it. Still, affiliate marketing allows me to relax a little and enjoy life more, all while knowing that I am earning a great living by promoting products that I use and enjoy.
If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog. 

Search for blogs that cover similar topics. Use a search engine and the search bar on blog hosting sites to find blogs that cover your topic or related topic. Read a few blog posts from the most popular ones, that show up high on the search ranking, have the most comments, or display a readership of 20,000 or more.[7] Get an idea for how much interest and competition there is.
It’s dependent on traffic. Traffic goes up and down and you never know when it is going to do a major dip. Most advertisers pay based on the number of views their ad will get. This turns you into a traffic monster. You start to look for creative ways to get any kind of traffic, no matter if it’s good traffic or not. This can easily lead to your site becoming another junk site that you try to avoid.

At the time of this writing, I’ve been blogging for only 1 1/2 years. And most of that time I spent on my podcast and writing my book – not blogging. And yet one day I realized – hey, I can make money blogging! The last time I published my monthly online income, my blog made $40,560.20.  You can find out more reading my income reports. And I don’t say that to brag, but to show you, you can do it.
Google Blogger supports advertising through Google AdSense, PayPal links, and limited affiliate links. If you use excessive affiliate links, fail to add relevant content when including affiliate links, or get paid to increase someone's search engine ranking, Google will move your blog much lower in the search rankings, greatly decreasing your audience traffic.[11][12]
Consider a free blogging service. Many people opt to create a free blog using popular services such as WordPress.com or Google Blogger. This is a good option for people who aren't familiar with web design, don't want to pay for their own hosting, or enjoy the ease and stability that comes with these services. These services do have limitations on how you can make money using them, however, so make sure your blog won't break the terms of service.
With the free version of WordPress, you don’t really have that much freedom to make changes to your site. Plus, WordPress actually owns your site if you use the free version (meaning, your site is technically not even yours). With the free version of WordPress, your website link even looks unprofessional; instead of a .com ending, your site will look like “yourwebsite.wordpress.com”.
Lets say, for example, that you refurbish and resell used smartphones out of your home. You could use a blog to attract visitors to your website where you list your current phones for sale. Your blog might cover topics about DIY refurbishing. On one level, it seems counterintuitive because you want people to buy your phones, but it also helps you build a brand and gain recognition.
