now I can only add these ads on my post directly.

You Can add ads through this plugin : http://wordpress.org/extend/plugins/adsense-manager/

 

You may also want to look at

Lots of options with this one

 

I got an immediate Threat Detection when I visited your blog. you may want to check into that.

 

You can put the adsense code in a text widget and it will show up on the homepage!!

 

Just add a text widget, then add whatever code you want to it .... no actual coding required, you can just cut and paste from any affiliate program ...
