Easiest way to rank fast with free SEO?

Hello,

What's the easiest way to rank fast with free SEO? I have read a lot about backlinking but most of people say you have to buy old Web 2.0's or that kind of stuff. I'm living in a country what currently doesn't have a service with expired web 2.0's. Are there other ways to rank fast with free SEO? Can I create web 2.0's by myself for fast rankings?
