Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.[citation needed]
Recycle items at the local recycling center if they accept collections. Many recycling sites will pay a small fee per pound of recyclable items. Go around your neighborhood collecting things like glass bottles, soda cans, newspapers, cereal boxes, and milk jugs. Have your parents drive you to the nearest recycling center and turn in your haul in exchange for money.[17]
When I used to write product reviews, I used to include just one affiliate link. For some reason, I thought that a single link would be enough and I didn’t want to run the risk of annoying readers with more links. However, one day it struck me that the reviews I was writing were quite long and by the time people got to the end of them, the link to Amazon was no longer visible.
Mow lawns in the summer if you can safely operate a lawn mower. Push mowers are safe for 12 year olds whereas riding mowers should only be used by teens who are at least 16 years old. Before you start mowing, ask your neighbor what height they’d like the grass, what parts of the yard you should cut, and if they have any special instructions (like not to mow too close to the flowerbed).[8]
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.[citation needed]
Tutor students. Many families prefer the flexibility of using an online tutor. Depending on your background, you could be simply helping a child with homework or providing college-level support. You need to have your own computer and high speed internet. Experience required differs among companies. Some require “strong experience,” while others require a specific educational background. However, most companies do require a college degree.
Test websites. Remote usability testing means getting paid to navigate a website for the first time and giving feedback to the website owner. Most tests take approximately 15 minutes, and you can get paid up to $10 for each test. A test involves performing a scenario on the client’s website and recording yourself doing it. For example, you might be asked to go through the process of selecting and purchasing an item on a retailer’s website.[1] 

If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
