How to Promote an Affiliate Product on a Site

Promote products that directly relate to your website's content. You will have better luck earning money from an affiliate that relates to the copy on your site. Advertising a new phone probably won't earn you much money if your site is about dogs, for instance.
Try to promote the product by incorporating it into your website's text. This is most easily done if you have a blog. You can write a quick product review or personally recommend a product.
Use graphic links that work with the design of your site. If you just slap a banner ad at the top of your page, it's less likely to get click-throughs than a smaller ad that works within the design.
Start an opt-in email list to send emails to prospective buyers. This is a good chance to personally recommend a product with links to your site or to the affiliate.
Pick ads that offer a discount or freebie. Some affiliate programs let you set a special coupon price, while others offer the same discounts to all affiliates. The more exclusive your offer seems, the more likely a visitor is to click on the link.
Consider using outside ad programs, like Google Adwords, to promote your affiliate link. Be sure this type of marketing is allowed by the terms of the affiliate program.
Remember to utilize search engine optimization (SEO) tools to get your site listed with the major search engines. You must build a strong customer base. Without customers, all of your advertising will be for nothing.

How to Earn Supplemental Income

Earn additonal income by establishing your own niche website. While it won't happen overnight, if you can add a page or two a day you will see results quickly. Try Site Build It! for a complete website service that includes hosting, training and support. (See link under Resources, below, for information.)
Earn extra money by freelancing online as a writer, web designer, graphic designer, or tech support. Check out RentACoder, eLance and other job bidding sites.
Get a second job nearby. Look for jobs at schools and hospitals, rather than retail outlets and restaurants, to improve job security. A night job as a hospital security guard or school janitor will be low-key and bring in extra supplemental income for your family.
Offer your talents or skills for hire as a musician, mechanic, baker, landscaper or handyman. Many services are still in demand, especially since many people will repair what they have instead of buying new.
Find ways to build up a passive or semi-passive income stream. The possibilities are numerous, including a rental business of paid-for items (houses, apartments, equipment, bikes, cars, farm tools), fruit orchard, or even more passive, residual income from online writing and websites.
Produce and sell food or necessary goods. As fuel and food prices rise, people are looking for local products and local solutions. From selling chickens and eggs, to raising beef for local sale, you can be part of the solution and earn supplemental income at the same time.
