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.
The one thing to be aware of with WordPress Amazon affiliate plugins is that you don’t want to use one that offers link cloaking. This is a method used to protect affiliates from a threat known as affiliate link hijacking. However, Amazon expressly forbids the cloaking of their links, so you’ll want to avoid plugins that do that or always be sure to disable that functionality if they give you the option.
Affiliates discussed the issues in Internet forums and began to organize their efforts. They believed that the best way to address the problem was to discourage merchants from advertising via adware. Merchants that were either indifferent to or supportive of adware were exposed by affiliates, thus damaging those merchants' reputations and tarnishing their affiliate marketing efforts. Many affiliates either terminated the use of such merchants or switched to a competitor's affiliate program. Eventually, affiliate networks were also forced by merchants and affiliates to take a stand and ban certain adware publishers from their network. The result was Code of Conduct by Commission Junction/beFree and Performics,[35] LinkShare's Anti-Predatory Advertising Addendum,[36] and ShareASale's complete ban of software applications as a medium for affiliates to promote advertiser offers.[37] Regardless of the progress made, adware continues to be an issue, as demonstrated by the class action lawsuit against ValueClick and its daughter company Commission Junction filed on April 20, 2007.[38]
Once you’ve set up your account, do note that Amazon requires you to use product links and generate income from at least three of them within 180 days. If you fail to do so within that time, they will close your account. If you are able to satisfy that requirement, Amazon will review your account as well as your usage of affiliate links once the first sale is complete.
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar. 

A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.[24]
I insist my writers actually read the books, test the cameras and use the software products they are reviewing. I encourage them to be as genuine and unbiased as possible, to point out both the pros and cons of the product. While there’s some temptation to hype up a product and only talk about its positive points, a real review will help your reader relationship over the long haul and I find actually helps promote sales.

During November 1994, CDNOW released its BuyWeb program. With this program CDNOW was the first non-adult website to launch the concept of an affiliate or associate program with its idea of click-through purchasing.
Analytics are limited. Unlike with conversions made directly on your WordPress site, you’ll be limited in terms of what you can learn about the people making purchases through your affiliate links. While Amazon does provide you with details about clicks and sales, you won’t get deep insights into who the consumer was and what they did on your site before they got to that point that you would with Google Analytics.
