First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.
Retain some control. If you upload photos of yourself, or friends/family with consent, it's worth going for the 'rights managed' licence option – otherwise you'll have little to no control over how your images are used (eg, you could star in an ad for haemorrhoid cream). See Alamy's page on understanding stock image licensing for more on the different types of licences.
Write pitches. If you have located a client for whom you want to write, send pitches, which are topic ideas for articles. Write pitches that not only show your expertise, but also demonstrate your enthusiasm for the topic. First, read the publication to which you are sending pitches to familiarize yourself with what they publish. If applicable, identify a specific section and send our pitch to the appropriate editor. Also, include a brief summary of who you are.
If the above locations do not yield information pertaining to affiliates, it may be the case that there exists a non-public affiliate program. Utilizing one of the common website correlation methods may provide clues about the affiliate network. The most definitive method for finding this information is to contact the website owner directly if a contact method can be located.
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online.
Two-tier programs exist in the minority of affiliate programs; most are simply one-tier. Referral programs beyond two-tier resemble multi-level marketing (MLM) or network marketing but are different: Multi-level marketing (MLM) or network marketing associations tend to have more complex commission requirements/qualifications than standard affiliate programs.
For example, when I first started back in 2009, I learned from a service called Solo Build It. I knew absolutely nothing about building an online business, let alone what “affiliate marketing” even meant. However, they changed my life and taught me how to build money-making websites online, which is what I’ve been doing with my life ever since. This is another great service to consider and you can read my review of Solo Build It here.
I’ve noticed that a lot of people who sign up for Wealthy Affiliate are those who are in dire need of financial help. They may have lost a job or may have suffered some other financial setback such as medical issues. The thing is, there’s no reason these people should stay away from Wealthy Affiliate, but many of them have this expectation that they can create a full-time income in a matter of weeks or even a few months. That is NOT the case. Remember, it takes an average business 3 years to profit. Fortunately, it will not take that long with an online business, but it will take considerable time and effort. If you need an income source fast, Wealthy Affiliate is not the place to provide that. Instead, Wealthy Affiliate teaches you how to build a real, sustainable online business over a period of time that will also last a long time.
One big difference between SkimLinks and VigLinks, however, is that once you’re approved by the company, you can choose to work with any merchant or program on its platform. SkimLinks has also published a white paper discussing its partnership with Buzzfeed, giving SkimLinks a lot of credibility. SkimLinks also has a higher tier of vetted merchants called “Preferred Partner” and “VIP” that both pay higher commissions than standard merchants.
In 1994, Tobin launched a beta version of PC Flowers & Gifts on the Internet in cooperation with IBM, who owned half of Prodigy. By 1995 PC Flowers & Gifts had launched a commercial version of the website and had 2,600 affiliate marketing partners on the World Wide Web. Tobin applied for a patent on tracking and affiliate marketing on January 22, 1996, and was issued U.S. Patent number 6,141,666 on Oct 31, 2000. Tobin also received Japanese Patent number 4021941 on Oct 5, 2007, and U.S. Patent number 7,505,913 on Mar 17, 2009, for affiliate marketing and tracking. In July 1998 PC Flowers and Gifts merged with Fingerhut and Federated Department Stores.
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. 
Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
