Use white space, so that the AdSense panel catches the eye.

Stick to only one topic per page – that should make it easier for Google to serve up highly relevant ads on your pages.

If you want to target certain high-priced keywords, use them in the file name, in the heading on the page, and in the first paragraph – in other words, use search engine optimization techniques.

If only a small number of pages on your site are displaying Google ads, try placing the AdSense code on more pages, especially those rich in text-based content

Try to keep your filter list small

Don't cheat and Ask Google if you have a question

lastly don't cheat! Cheating will get you nothing, sooner or later your account will be terminated and all your money will be gone, so play fair. It is illegal to place texts like "Please support us and click on the ads".
