1. Find a medium through which to publish online — one that will allow you to run Adwords ads. The obvious and simplest choice is to start a blog, something of which Google is very fond. Start a Blogger or Wordpress blog for free and start creating content.
2. Use the Adwords keyword tool in order to help you earn the most amount of money online. There's two ways this tool will help you. The first is is finding keywords that receive high search volume. If you write your content around themes that don't receive any searches, you won't make money. Get high search volume topics, such as health or personal finance, and write around those central themes.
3. Secondly, use the Adwords keyword tool to find keyword phrases that have high cost per click. If advertisers are paying several dollars for each click, you will earn more money every time someone clicks those ads.
4. Sign up for Google's AdSense advertising program and insert the given code to run the ads on your website. Google will browse your site to run ads that are related to the keywords you are using. These are inobtrusive, relevant ads that blend right in with your website. Every time someone clicks one of those ads, you'll make money.
