Blogoscoped has some great Adsense tips here.

Most interesting is this part:

"When it comes to context sensitive targeting, you can increase or lower the importance of certain parts of your page. "

which you can direct Adsense's attention to parts of your page.

Enjoy.

Those are some great tips. Again, common sense stuff. But thanks for the link.

Practical knowledge is good knowledge. Thanks for the post. Though common sense stuff, strangely it's not common knowledge stuff for many.
