Perhaps the most popular way to earn a passive income is by launching your own blog. It only takes a couple of minutes to set up and is cheap to start - just purchase your domain name and pay for hosting.
After that, start creating amazing content that people would be interested in reading or sharing. For example, if you’re an accountant that has helped small business owners with their taxes, then that could be your blog. I personally have my invoicing blog to help customers know everything there is to know about invoicing. This draws thousands of signups a month.
Make sure the topics you write about are popular. If you still love your pet rock, I doubt there would be enough people visiting your our site to monetize it. But, you never know.
Once you’ve gained a following, you can start making money from of your blog by:
Earning commissions as an affiliate. This is where you push other people’s products or services on your site. Make sure these products or services are relevant to your blog. For example, that accounting blog could become an affiliate for accounting or invoicing software. Once you find an affiliate partner you’ll be given a unique code so that whenever a visitor clicks that link on your site you’ll earn your commission.
Sell advertising. If your site has the traffic to become an affiliate, then it may also be good enough for advertisers to purchase ads on your site. You may start off small, like making under $20 per ad. But, you may eventually be able to charge triple digits. Again, your site must be quality.
Find sponsors. This is slightly different from just selling ads on your site. Sponsorships may be a one-off piece of sponsored content or permanent logo embedded in your footer.
