If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
Although it may take a long time to increase your affiliate marketing income, it is completely possible to do. You will need to be willing to invest time and effort into building your audience and perfecting your affiliate marketing process. Even if you never reach the amazing levels that these bloggers have reached, you can still make a good income.
The first thing to do is to join an affiliate program then select the products you intend to sell. The owners of the products would provide you with an affiliate code you can use for referring traffic to the main site. Also, you will be offered banners, text links and several forms of creative copies in which you just copy and paste the code on your own site to refer traffic. Any interested customer who clicks on the links from your website will be redirected to the main site where the product is sold and if they pay for the product or subscribe to a program/service and indicate you as the referral, you get a certain percentage as commission.
Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.

It is important to realize that it is possible to earn an income with affiliate marketing, but it not easy to earn an income with affiliate marketing. It will take hard work and dedication to build a lucrative affiliate marketing website. You will need time to build your audience and gain their trust before you are able to perfect your affiliate marketing strategy.

If you’re a skilled worker in a specific niche, like marketing, design, or software development, there are specialty marketplaces that cater just to you. These are amazing places to make money online as you know that the people visiting them are looking specifically for the skills you have. Check out places like 99Designs or Dribbble for designers, Cloudpeeps for marketing and SEO professionals, and TopTal, Crew, or Gigster for high-level software developers. Once you've built up your development skills, you can begin building a brand for yourself as a higher-value consultant and start charging brands for larger projects like implementing an entire WordPress security overhaul or migrating a website from http to https.

19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.

Obviously, around Christmas period, people tend to buy more, therefore, post recommended products before this period to take advantage of sales that will go on on Amazon affiliate marketing. It is better to start creating a seasonal schedule for your blog posts early enough. There are several holidays, so you can plan ahead of them to make more sales and earn your commission. 
_{Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.}

Amazing and thorough breakdown of how it all works! Thank you so much for sharing! a group of 3 friends myself + 2 are about to start affiliate marketing together. Since many advertising rules have changed with affiliate marketing (facebook ads etc.) and many articles have not been updated since, weʻd love any advice or suggestions you have for 2018!

Target 1-2 Keywords Per Article – until you can successfully rank for 1 keyword for an article, don’t try targeting 2. Once you get the hang of it and are ready to write an article around 2, choose a secondary keyword that is a synonym of your primary keyword. An example would be “Slow WordPress Site” and “Why Is WordPress Slow.” Then craft your article title/SEO title/meta description to mention individual words of each – while making them read nicely.
At the time, I had a ton of people reaching out wanting to hire me (I ranked my self #1 in Google for WordPress SEO Consultant, WordPress SEO Expert, many other good keywords). Unfortunately I struggled with basic things you need to run a service-based business… keeping track of clients, time management, and making sure I was charging clients for my time (and getting them to create content which often seemed impossible).
Dog watching. One of the best jobs for stay at home moms who love their four-legged friends.  Rover.com matches dog owners who need pet sitting with pet lovers who want to help. Create your profile and set your prices. Must be in a city populated enough to find business, but the potential to earn hundreds of dollars per month is there. (Heather in Seattle nets $500 to $1000 per month this way.)
Once you have the affiliate links you need, it is time to present them to your audience. As you start using affiliate marketing to talk about products, you need to be aware of how your audience perceives you. If your website appears to be only after their money through an overwhelming amount of affiliate links, then they are more likely to simply leave your site.
