Become an Amazon Associate and then use Keyword planner to find an in-demand niche: With more than a million different products to choose from and up to 10% commission the sales you drive, Amazon’s affiliate program is a great place to get started. Browse their available products and see what connects with you. Or take it a step further and use Google’s Keyword Planner to quickly check how many people are searching for a specific term. With affiliate marketing, the more relevant traffic you can pull in, the more you’ll make off your site.
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.
If you are a fast reader and have a good grasp of grammar and language then editing may be a good freelance role for you. Editing is a great way to quickly make money online, and there are always editing jobs available on the freelance job sites. Editor’s usually get paid per word, so the faster you can check through work the more money you will make per hour.
If you are building a site that has the potential for information that will never age and remain useful for your audience, you have the opportunity to create what is known as evergreen content. It's important to carry out extensive keyword research before planning any evergreen content for a site like this, as your site could hugely benefit from the proper usage of keywords within such content. 
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
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.
If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.
If you offer freelance services or have a physical services business, then creating a blog is a must. On your blog you can write about the services you offer and how they will benefit your clients. Importantly you can add a ‘Services’ page, outlining the services you provide, what they include, and any other important information potential clients may need. This is an effective way to promote your services, generate leads, and increase your revenue.
If you already have a website or blog, look for vendors that offer related but noncompeting products and see if they have an affiliate program. Stick to familiar products and brands—they're easier to sell. To promote them, place simple text or graphical ads in appropriate places on your site, include in a blog, discussion forum, or mailing list links to purchase products that you review or recommend or create a dedicated sales page or website to promote a particular product.
Ideally, you will already have a website that contains articles and other affiliate offers similar to the ClickBank products you want to promote. If you haven't set one up yet though, don't worry. WordPress is a great free content management system that you can use to start a website and begin publishing articles immediately. Use your articles to draw readers in, then present your ClickBank affiliate offer within the article. You may also want to develop a newsletter for your own website and use it to promote your ClickBank offers to your audience as often as possible. (See: How To Monetize Your Website.)

Pretty Nice Article Gael. This is much better than playing the waiting game of 4-6 months for the site to rank in Google. Much faster to test the funnel right away with paid traffic and get leads in your funnel for future marketing as well. These funnels might take time to build initially but once set they are truly source of passive income unless offer is taken off.
