I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
If you live in an area where Uber or Lyft operate, why not become a driver? If you're looking to make some short-term cash, you can definitely rake it in by working for one of these popular car-hire apps. As long as your vehicle fits within the specifications of their program, and you have a clean license, you could do this on the side, especially if you're in a crunch for cash.
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.
It is important to note, however, that StudioPress is now a subsidiary of WPEngine which is the company that actually does the web hosting on which StudioPress’s Genesis framework runs. The affiliate program only works with choosing the StudioPress framework and themes, not the actual hosting on WPEngine. WPEngine has a separate affiliate program for its hosting services, which yes, is a bit confusing.
StudioPress is a WordPress hosting service and framework that is designed to make setting up and running a WordPress site much simpler and easier. StudioPress comes with its own unique themes and SEO tools, collectively known as the “Genesis framework.”. Their affiliate program is solely for referrals to pay for a StudioPress framework account or buying a StudioPress theme. Previously, the affiliate program also included web hosting, but this is now managed separately by StudioPress’s owner, WPEngine.
Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".
