Websites generally make money in 1 of 3 ways. They sell their own products. They sell advertising space, or they enter affiliate agreements. Affiliate agreements are a way for website owners to earn a commission from sales made on other sites. I use affiliate agreements.
For example, I have an affiliate agreement with Amazon.com, so if you click on this link–Amazon–and then buy something at Amazon, I will get a small commission. This never ever increases your purchase price–not even one penny!
These commissions help me pay for things like web hosting services, web-design products, graphic designers, etc. If I’m lucky, I even have a few dollars left over for myself. Thanks so much for your support. It is you the readers who keep this site alive!
