This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.
​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.
Actually, yes. I have created a new problem solving model called C.U.R.E Problem Solving ™ 4 Easy Steps found at me site and I was planning on using it to address a new niche site for me on nutrition.

There are plenty of websites on the internet that offer digital marketing courses for free. You can sign up on those sites and learn digital marketing through various courses and programs. Those courses can help you develop the understanding for the field and get a certificate as well, but they are not as authenticated as professional certificates and tend to have low completion rates. These free courses don’t usually offer any interactive projects, practical hands-on learning, or live lectures. Although some of these free courses can help you get your feet wet, if you’re serious about learning digital marketing, you’ll need professional training with a certified online education program. As the old adage goes, you typically get what you pay for.
How to Monetize: Affiliate marketing works well when you discuss products on your blog. For our fish tank blog, we would link to all the things you need to buy for an aquarium and then when people click on that link and buy that item (and other items they purchase with it with some exceptions) you get a percentage of the purchase. Amazon Associates is the best-known affiliate marketing program, but there are others like Impact Radius, ShareASale, Commission Junction, ClickBank and Rakuten too.
I just started getting into dirt bikes.  They are SOO much fun!  Unfortunately, I’ve found it difficult to find good answers to the things I’m searching for  on newbie dirt bike topics.  For example, “How many CCs should I get for a kids bike?”  Or “What protective gear do most kids wear for dirt biking” or “What is the best beginner adult dirt bike?”  If you can answer those questions and create a helpful site answering them, it could be quite profitable.

3. I’ve seen this with a lot of product ideas. Including one that I have launched myself, where some of my competitors are selling a similar item at a much lower price. It’s useful to know this because if you are going to launch with a higher priced product then it needs to be a higher quality product and you need to be able to show that in the product listing. In my case, I am selling a higher end sleeping bag that has added features, better fabrics and more warmth than the budget versions.

Type of site: Just make this a niche site for the first several years.  Don’t waste a ton of time making a podcast and an in-depth youtube channel.  Make a few videos to show some setups but mostly just write blog posts.  If you create a podcast episode today, nobody will listen to it again after a few months.  Write blog posts that will last.  There is no competition here, so don’t get bogged down with social media and crap.  Just write!

"Create your own products and services," financial blogger and life coach Michael Tamez tells Bustle. "Any company you could ever work for can replace you at any time. However, your individuality can never be replaced! I encourage you to explore your creative talents and abilities more. What are you good at? How can you monetize that talent and perhaps even build a business out of it? Have you experienced something extraordinary in your life, and because of it, have tons of knowledge and wisdom to share? ... Creating your own products and services can create steady streams of residual income, which pays you continuously, even when you're not working. Essentially, you bust your ass once and get paid for the rest of your life — even when you're sitting on the beach, sipping coconut rum. Just remember this: When you invest in your creative abilities, you become irreplaceable!"

My goal with this site is really only to write about 25-30 pages with information as I learn about boats and do customizations to my boat.  I’m also adding a forum.  Forums seem to be very popular with boat owners so I’m anxious to have others generate content for me.  I don’t have huge plans for this site, but I’m sure it will bring in a few thousand a month if I don’t fizzle out.  This is going to be my fun project for the next little while.
