You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low. You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
So, I put together a free master course for you to take that spreads out all of the work involved in starting a blog, into a series of action-packed lessons. My free course breaks the entire process of starting a blog down into an incredibly simple 7-day process for going from 0 to publishing (and promoting) your first blog post in just 1 week. I can't recommend it enough.
Tradedoubler was founded in 1999 by two young Swedish entrepreneurs. They have offices in the UK and multiple countries throughout Europe, including Sweden, Germany, France, Poland and Spain. Their focus has always been to provide smarter results for both clients and affiliates through technology. In 18 years, they’ve amassed an army of 180,000 active publishers, connecting them to over 2,000 merchants in Europe and the UK. Many of these merchants are household names.
Shopify has three different account types as well as standalone third-party products like themes and apps. Commissions are paid for sales of any of these products, including users who sign up for a 14-day free trial and then convert to a paid account. Shopify also has a wide range of blog posts, webinars, and video tutorials that can be linked to with the standard commission paid on any sales that are generated.
JVZoo was founded in 2011 and has since rocketed to near the top as one of the most popular affiliate programs out there. JVZoo is unusual in that there are no upfront costs for either publishers or merchants (advertisers). JVZoo’s income is exclusively from charging fees (to both the merchant and the affiliate) after a sale has been made. It is also unusual in that it pays commissions “instantly” via PayPal rather than once a week/fortnight/month like other affiliate programs.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent.

If you're ready to enter the ecommerce fray, you could sell your own stuff. Of course, along with selling your own stuff on your own website comes a whole slew of both responsibilities and technical configuration and requirements. For starters, you'll need a website and a hosting account. You'll also need a merchant account like ones offered by Stripe or PayPal. Then you'll need to design that site, build a sales funnel, create a lead magnet and do some email marketing.
So actually, the reason I personally signed up for Wealthy Affiliate is likely much different than the reason YOU want to sign up. Chances are, you want to learn about how to make money online legitimately, learn how to build a website, how to blog, and more importantly, how to earn money from that blog. I wasn’t looking for that. I already knew how to do all that stuff. Instead, I signed up as a way to vet the training, tools, and resources provided by Wealthy Affiliate because I wanted to see if it was something I could promote on this very website you’re reading.
Check if you need a model release. Photos of people can only be sold for commercial use if they've signed a 'model release' that gives you permission to use their image (children need a parent/guardian to sign). Without a release, these photos can still be sold for editorial use, as long as they were taken in a public place – eg, if you submitted a 'breaking news' shot with people in the background. If there's any doubt, always ask permission.
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.
