There’s a good reason why ClickBank is still a strong contender, however it does tend to focus more on digital products which may be of questionable quality. Yes, the review process is more professional these days, but it’s still primarily focused on selling digital products, especially “how to make money” courses and the like. That being said, there are some genuinely high-quality products on offer, and few affiliate programs are bigger than ClickBank, especially in selling (primarily digital) books.
The site has a lot of links, and the long form content that the site showcases is one of the reasons why it ranks so well.  Most of the content on the site is extremely focused, and very informative.  It's pretty typical that an article on this site is over 2,000 words.  While longer content doesn't always mean better, Google does base some of its ranking factors on how much content is on the page that covers the topic in its entirety.  The more in-depth the article, the more likely the user is to find the answer they were looking for, which is why this website has so many articles that rank very well.  Each article is very complete and provides great information on the topic.  If I had to guess, the site is probably making over $20k per month based on traffic estimates.
Affiliate Marketing is based on revenue sharing and is a type of incentives program. The goal of marketing is to build an alliance with a brand, product, service, or company, and market these services to people online. The Affiliated Marketing consultant shares in a percentage of the company’s profits in exchange for bringing them valued business and gained exposure. The same marketing advertising concepts used in television and print ads are applied here, only the platform that is used to entice and attract the consumers is on the internet.
Have relatable products to the content on the site. Don't advertise the latest video games for sale on a site that's about fishing. The traffic coming to your site is full of potential customers which have clicked on your site for a reason; the site content. Having products which relate to that content can dramtically increase your amazon affiliate earnings.
The thing I like the most about the site is the way it feels.  All of the Amazon affiliate links are extremely well integrated, and they've done some custom design work to make some of their images feel interactive.  Another trend here is that the owners of this site, own similar sites in several other niches.  You can tell which sites are owned by the owners of this site when you look at the bottom of the site and notice that they link internally to their other web properties.  This is becoming a popular trend, with the folks over at DigitalMarketer.com doing the same thing with some of their projects, like SurvivalLife.com and DIYReady.com.  It's hard to estimate the total revenue for this site, but because the call-to-actions on the site are so good, it would not surprise me if this site was doing over 70K per month in Amazon Affiliate income every month.
As you can see the two types of programs are different. Even so, there are some similarities. The biggest one, as you can guess, is that incentives drive people to promote. Whether it be promoting a link in a piece of content, like in affiliate marketing. Or sharing a referral link with a friend, as with referral marketing. The incentive isn’t the only thing on the line, however…

generic keywords tend to have high search volumes, but they also tend to have high competition or low buyer intent. They're good to target as part of your overall strategy (just don't try to compete on PPC campaigns). Long-tail keywords, like "Fat loss for mothers" are generally more specific, have higher buyer intent and could be effective drivers of traffic to your site. =) They should be the primary focus for your SEO and marketing.
Be sure to check what kind of customer support you can expect from your affiliate program once you have signed up. Do your research online and if possible, speak to other sellers using the program to get their thoughts. Can you speak to someone via phone or Skype or do you have to wait 72 hours for email responses? Be clear on this because trust me, you will need support at one point or another. 

File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you. 
This site is an example of what many sites are doing these days.  They are “niched down” into brackets of certain products, and creating an online multimedia experience in the form of an online magazine style site.  There's lots of large pictures, some videos, and it looks like a true media property.  Chances are that you'd need to hire a designer to get a similar look and feel for your own website if you were to attempt it.  From a revenue perspective, this site is more than likely doing more than six figures in total revenue if I had to take a guess, just based on their organic traffic numbers.
Sometimes, individual entrepreneurs with great products are worth a look, although you should check them out first and do some research. Entrepreneurs or companies may run their own affiliate program and you can apply directly to them to promote their products and services. Finally, Amazon is always an option as you can be an affiliate for just about any type of physical product on their network.
Flexoffers is another huge affiliate marketing network. They pay you (the affiliate) a lot faster than others in the industry. It has more than 10 years of experience in the field. While they do not offer anything that is neither groundbreaking nor revolutionary, they do provide a solid array of tools and features that will surely aid you in your campaigns. In addition to the fast payouts, Flexoffers lets you choose from thousands of affiliate programs to promote, offers various content delivery formats, and more. 

Affiliate marketing should be viewed as a long term business, so give careful thought to your affiliate marketing niche before you start developing a website and building a mailing list. The subject should be something you enjoy and have some interest in, or running the business could become a chore. Remember that the goal is to make money, so avoid any ‘vanity projects’ where there are little or no profits to be made.
TheSpruce.com is an interesting website for several reasons.  It started taking off in early 2017, specifically as a kitchen + food website.  The traffic growth is massive, and the website now ranks for millions of rather competitive keywords.  They have a small staff, and early on, focused on producing recipes, with high quality pinnable images (Pinterest) and even some very detailed videos that showcase how to cook or decorate parts of your home.  They accept contributor posts, but not unsolicited guest posts – and because of the domain authority, I'm sure there are food bloggers lining up to provide them extremely valuable content for free as long as they are featured on the site.
JVZoo’s strength is that it allows experienced marketers to gain access to product launches and a huge range of online courses while setting up sales funnels and customized landing pages. It’s definitely not for someone who wants to monetize a blog or earn money by having users click through and buy physical products. If you’ve carved out a strong presence online in the marketing space, JVZoo might be a perfect fit.
Despite its older origins, email lists are still a viable source of affiliate marketing income. Some affiliates have email lists they can use to promote the seller’s products. Others may leverage email newsletters that include hyperlinks to products, earning a commission after the consumer purchases the product. Another method is for the affiliate to cultivate email lists over time. They use their various campaigns to collect emails en masse, then send out emails regarding the products they are promoting.

This twice-monthly publication is apparently full of "informative articles, a question and answer section, site updates and more." This affiliate will probably use this e-zine either as an additional place to promote affiliate products or to get his readers back to his website by providing snippets of new articles with a "read more" link. By getting readers back to his site he's able to expose them to more promotions.
For example, if I talk about how cool a product is, and then you find out that I’m an affiliate for them, wouldn’t you as a conscientious observer become skeptical as to whether my information is biased, if perhaps I’m only saying how cool something is because I can get paid for it? Wouldn’t that make you question my integrity with other things I say as well?
