What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
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. 
•The website has no contact information. A legitimate business has a way for you to reach them. Look for an "About" page that offers information on the company or CEO, along with a phone number, address, or contact email. (Try calling the number to see if anyone answers.) A website with only a contact form and no other way to get in touch with an actual human is suspicious.

Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
Tools. You don’t need much to work as a home-based freelance writer, but there are some tools that you must have. The most important will be your computer. Get the fastest Internet access that you can afford. It doesn’t matter what kind of computer you get. Just make sure you’re comfortable enough to spend a lot of time with it. Most clients will request that you submit your work as a Microsoft Word document, so make sure that whatever programs you use are compatible. In addition, because you’ll be spending so much time at the computer, make sure that you have a good work area with proper lighting. Some clients will want to be able to reach you by phone or Skype, so have both set up and accessible. You’ll need an invoicing program, such as Freshbooks, and a good bookkeeping system to keep track of sales, orders, and accounts receivables.
The Nielsen Global Connected Commerce Survey conducted interviews in 26 countries to observe how consumers are using the Internet to make shopping decisions in stores and online. Online shoppers are increasingly looking to purchase internationally, with over 50% in the study who purchased online in the last six months stating they bought from an overseas retailer.
Outsourcing is the new and dominant wave of the business world. As businesses shed employees, they increasingly turn to independent contractors to supply what in-house staff used to do. One of the ways they do this is through virtual assistants. These are people who provide certain tasks online. Businesses can use virtual assistants as much or as little as they need to. If you can make yourself available to multiple businesses, you might have plenty of work without ever leaving your house.
An influencer is an individual who holds the power to impact the purchasing decisions of a large segment of the population. This person is in a great position to benefit from affiliate marketing. They already boast an impressive following, so it’s easy for them to direct consumers to the seller’s products through social media posts, blogs, and other interactions with their followers. The influencers then receive a share of the profits they helped to create.
Forms of new media have also diversified how companies, brands, and ad networks serve ads to visitors. For instance, YouTube allows video-makers to embed advertisements through Google's affiliate network. New developments have made it more difficult for unscrupulous affiliates to make money. Emerging black sheep are detected and made known to the affiliate marketing community with much greater speed and efficiency.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
