I'll just run through a quick list of some solid ways to generate income on the web:
- Build a web site that offers a valuable service, and run AdSense on it.
- Build a web site with high Page Rank (PR) and Alexa rank, and sell Text Link Ads on it.
- Build a decent web site or blog and sell it.
- Start a blog and sign up with pay-to-blog programs. Each paid post will get you around $5 at the least, and much more if your blog has good traffic, subscriber numbers, PR, Alexa rank, and Technorati authority.
- Get paid to write content for other web sites, blogs, and eBook sellers.
- Write your own eBook and sell it.
- Sign up with an affiliate program like Amazon or ClickBank and advertise their products.
- Buy domain names with proven traffic and park them with a site like Sedo that pays you for every click an ad on your page gets.
- Sell your stuff on eBay.
- Sell your web design or coding skills on a job-by-job basis.
- Trade stocks or currencies (Forex) online.
