How to Monetize a Blog

I've heard the question over and over: "How do I monetize my blog?"
There are several ways. Here are some ideas: 

• Become an Amazon Associate 
• Add Infolink, AdBrite or Chitika
• Try a pay-per-post service
• Join Commission Junction
• Give the Google Affiliate Network a try

I've tried a few of these with my blogs. It takes some testing and waiting to see what works. I'd recommend which ones work well for me, but ever blog is different. Give one or two a try.
