There’s no limits to the number of affiliate programs you sign up for so applying for one today will not prevent you from picking another one later on.  In fact, being a member of more affiliate programs simply gives you more options in terms of products to promote plus they’re pretty much all free to join.  You can always leave a program if it’s not working out for you or there are no products you want to promote.
Airbnb is a concept that has only been around for a few years, but it has exploded around the globe. Airbnb allows people to travel all around the world and to stay in accommodations that are a lot less expensive than traditional hotels. They do this by staying with participating Airbnb members who rent out part of their homes to travelers. By participating in Airbnb, you can use your residence to accommodate guests and earn extra money just for renting out space in your home.
The Coinbase Referral Program allows content creators (or anyone online) to earn a bonus for each successful referral registered to their account. Referrals are powered through links and require the new customer to sign up for a Coinbase account. If the referred individual initiates a buy or sell of $100, within 180 days of the account opening, both receive $10.
The exciting part with this hands-on class is that you not only get to hear about ways to grow your professional persona using social media, but you will actually do it! “What Is Social” is the first in a six-course specialization offered by Northwestern University (a top university in the United States). Once you finish this first course, you can continue on with the next steps of the track: Social Media Marketing: How to Profit in a Digital World. (The first course is free; the full track costs $426.) 

Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.
Clickfunnel has a great affiliate program that pays anything from $30 to $500 per sale and one of the great features of it is the fact that it pays lifetime commissions. This means that you will earn commissions on every customer you refer as long as they are a Clickfunnels customer and buy their products. For example, if one of your customers that you referred a year ago bought a new program today, you’ll still earn a commission from that sale. Lifetime commissions are a great way to build a passive income source.
For example, you can design digital products, like animal clipart or a downloadable wedding poem that could be printed by the customer. Your design could be resold thousands of times without needing to create each item or ship it. Once you create your digital product and list it on a site like Etsy or Ebay, the revenue flows in with little oversight.
