Clickbank U. was seriously lacking in their affiliate training course. That's not unexpected though! Their affiliate training course seemed like a side project, instead of a main course. For serious affiliates, I recommend joining the top affiliate training center online. They've been training successful affiliates for over 15 years now, including myself (six-figure income earner).
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. 
I think Drop shipping is the best way that can help you make money online. It is the only way that allows you to start an online business without investing capital in inventory, warehouse and to buy products individually from a wholesaler and ship them directly to your customer. Moreover, with my drop shipping experience, you will learn key strategies that you won’t learn anywhere else to help your online business grow and thrive.
I would not bother boosting Facebook posts. That does not perform well. The best strategy is to create a custom audience of your visitors and email list. You may want to use that to create a look-alike audience as well. Then have a sales funnel and email campaign. For instance, you are going to get much better conversion rates from a warm lead who has already received some great free content.
While it often takes a significant amount of time and hard work to build up your affiliate income, if you have the ability to regularly publish high quality content that drives in targeted traffic to your website, this online revenue source can become quite substantial. Follow along with my experiment growing two completely new blogs—one finance blog MoneyTalk and one called SmartWP about WordPress, into additional revenue streams for my business.
Paid traffic, such as PPC or banner advertising, is usually more controllable and scalable. If what you're doing is working, you can spend more to grow your traffic. It also has the advantage of being able to start very quickly, if not immediately. The main disadvantage of paid traffic is that it can be quite expensive and requires a lot of supervision to avoid losing money. Paid advertising platforms such as Google AdWords can also have strict requirements regarding advertisers and ads, so be sure to pay close attention to all rules and warnings.
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
Just be sure to put a lot of care into your product listings. Everything from the titles you use, to how effective the description is at convincing potential buyers your product is better than the rest, and even taking care to shoot high quality product photos can have a dramatic impact on your sales. I recommend using photo editing tools like Fotor, which gives you the ability to edit your images, create captivating graphic designs and more.
Tip: Aim for products with reasonable commission. No lower than let’s say 40 percent, to make your efforts worthwhile. Also, you should note that ClickBank deducts transaction fees from a sale. Here’s a calculator to help you calculate your actual commission. More so, you need to remember to disclose all your affiliate links and mark them as nofollow. Here are a few reasons as to why you need to do this.
