Running a coupons website can be very lucrative. Find a coupon niche, select a WordPress coupon theme, and then display relevant coupons on your site. When your audience uses the coupon codes or discount links, you will earn an affiliate cut for example you could set-up a site dedicated to iHerb Coupons or add a page to your website with Web Hosting Promo Codes. Coupon websites are quite high maintenance as they need to be constantly updated with new offers. However, if you build up an engaged audience and allow them to post coupons and discounts they have found themselves, then quite quickly your workload will reduce.
Now as to your comment on traffic it is true, traffic is important. But the truth is, acquiring traffic is easier than converting it. Plus we have many posts dedicated to traffic generation on this blog. Simply check this post, this post or this post. But must importantly, the reason why people struggle with traffic is that they try to promote a sales page or a heavily biased piece of content. Nobody wants to share that, nobody wants to link to that, and as a result you don't get traffic and blame your lack of success on traffic (like you did in your comment above).
Signing up with Google AdSense will enable you to make money from advertising on your blog. Google AdSense will place relevant ads around your site, and if your site visitors click on these ads, you will earn a fee. Although each click only amounts to small change, if your blog has high levels of traffic, this will quickly amount to a reasonable sum.
Tools & Resources: I’ve written a pretty comprehensive guide on the best web design software that covers both free and premium software packages. If you’re serious about becoming a web designer, then I recommend purchasing the full Adobe Creative Cloud Suite. At $49.99 per month, this is probably a bargain considering what you can achieve with this set of tools.
Contact the company directly. If you use a product or service and want to recommend it but you can’t find evidence of an affiliate program, consider approaching them and asking if they are willing to set one up (maybe with your help). Highlight your audience and the value of your recommendation. Explain that an affiliate program is simply rewarding happy customers (you!) for promoting, and they don’t have to pay until a sale is made.
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.
2. Finding the correct products to promote – If you’re promoting crap products, no one is going to buy them. No matter how good you are at marketing. Finding the correct merchant is one of the most important steps on your affiliate journey, you need to be promoting attractive products that people want to buy. That way, half the work is already done for you!
Epic post! I've been hunting around various sites like Pat Flynn's and others, but they never put everything together as you have. Now it starting to make sense for once. So, I'm a newbie and don't even know the different between internet marketer and digital marketer or what this type of business is even called. I just want to learn this business and create a small passive income online in any niche. Because I know very little, I was actually planning to use this very same Sales Funnel in your diagram and all the tools mentioned to make my first couple of bucks online.
