How can I earn more from my adsense?

Question

Hi,
I have ads in my website following system

    * 120x600 image ads (in each page)
    * 728x90 image ads (in each page)
    * 728x15 Ad links (only in internal pages)
    * adsense for search

Do I use the right ads for my site (type and size)?
Do the ads fit the color of the site?
Are the ads positioned correctly?
What else can be improved so I will earn more?

You will earn more from adsense only if you promote your site through various source like directory submission service, various forums, social networking etc.
