Just like to add 1 additional "CON" to the list of Pros and Cons of Clickbank. Their rule on paying out the commissions earned. You must have 5 sales all from different credit card accounts before they will pay you what you have earned. That flat out sucks!. Affiliates work hard to get even 1 sale and because of Clickbanks rule, lose that money over time if they cannot get another 4 sales, the commission keeps reducing steadily if 4 more sales are not forthcoming. Clickbank has got to change that rule, which many feel is illegal!. A sale, is a sale, and the commission must be paid out. Basically, Clickbank is "Ripping-Off" affiliate marketers.
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
Affiliate marketing is an ideal solution for those looking to gain control of their own income by focusing on performance-based revenue options. Working in tandem with a seller, a motivated affiliate marketer will be able to achieve a passive income from the comfort of their home without worrying about producing their own product or service. Although the success of the job does depend on the affiliate’s marketing skills, it can prove to be an effective way to meet your income goals as either a primary career or a profitable second job.
Considering that you have a finite amount of time, passive income should make up a large part of your work. And if you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Simply this. Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income?
Don't sacrifice morals for a quick buck — At the outset, you'll want to do all sorts of things to make money online, but don't sacrifice your morals for a quick buck. Not only will you put people off, but you'll lose Google's trust. You also shouldn't concern yourself with things like Adsense or other ads on a blog before you have around 100,000 visitors per day. Yes, per day. 
Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes. But many successful apps, particularly those in the Apple and Google stores, are created and marketed by individuals and small businesses. In fact, independent developers made $20 billion in the App Store in 2016 alone.
