for me i just click the customize this Page  then drag then drag the Custom Text/HTML widget anywhere of the Section of the Page I want my GOOGLE ads to appear then Copy & Paste the  google adsense code

It works for Adsense.

It will take some time for Adsense ads to show if you are using adsense in the site for first time with a new ads code.

The adsense finally replied they said i have less content .

i have not activated forum or blog plugin. i get only 1000visits/day..

what should be the problem no post like blog or forum or less traffic?

Both is the problem. Many ads network look for sites with more content and more traffic. They do this to stop using the ads network just for revene.

The best way is to create a free blog site with more content, get the account approved and then use it in other sites.

The main Adsense TOS is that data content should be there. Its not necessary that blog or forum is there. But some textual contents.

Thanks purus.
