Adsense Ad Size - Which size to use ?

I have tried using a lot of different ad size for my websites and blogs.

The one that generates the most clicks are the LARGE RECTANGLE 336 x 280 .

Placing the ad in between your content will generate more clicks for you provided your content is relevant.

Placing the ad at your main page just after your introduction content works well too.

Try it.

Please do give your comments.
