Increase how well the Ads pay

Your option will be limited with an established sites because you have to keep web pages relevant to the site theme, but you can create new sites to cater to more expensive keywords. You can do this by going to Google AdWords and see what advertiser are paying per click (you do not have to sign up to do this). For example, these are some words and recommended bid:

• Well, you get the idea.
  • $1.56 - "webmaster"
  • $20.00 - "web hosting" WOW!!!
  • $0.62 - "forums"
• Create web pages relevant to your site, but optimized to the selected keywords.
• Avoid the use of low paying words that may confuse Google AdSense.

I hope this basic tutorial will give you a good foundation and allows you to become a more successful advertisment publish, that is, to make more money with Google AdSense.
