1. Build a website. Blogger and Wordpress offer free blogs, and you can buy a domain if you don't want the 'blogspot' or 'wordpress' sub domain name added.
2. Choose A Niche You Want To Promote. It is easier to get sales an products that you know something about. Use your website to promote products similar to your niche and it will be easier to convert leads into sales. Many advertisers make the mistake of promoting a wide range of products when it is easier to sell when you are viewed as reputable.
3. Choose Quality Products That Have High Conversion Rates. Having the most expensive products doesn't mean people will buy it. The more inexpensive the product, and the better the quality and conversion rate, the higher the chance they will buy. Search around for sites and other affiliate programs that have the right type of products you want.
4. Promote your website. Make accounts with YouTube, Myspace, Stumbleupon, Digg, and Facebook and invite users to check out your website. Make videos on youtube talking about your website and interact with others in the community. Some people will promote you if they find your website helps them, and that leads more people to your page, leading to more views for the product you sell.
5. Consider making a free members area. If people are interested in your website they will join and you can add them to your mailing list and offer them products occasionally. Don't spam them though. You want to build trust and actually offer them helpful items.
6. Keep Working At It. There are many ways to make a quick buck, but they can not compare to the lasting effect of building traffic and interest in your site. Keep working at optimizing your website and fine tuning the products you sell. Mess around with features and bring freshness to your page and you will benefit. You too can have success with affiliate marketing if you work at it.
