Adsense not showing real ads on my homepage

hi evererybody, nice to see you all here.

Ok people, i'd installed mod Ad Management on my site base of SMF (named Forum Informatika AKA ForumIF : http://if.web.id )

The adsense show its real ads in any place of my site except index.

Can any of you explain this problem, why the adsense just show public service ads in my homepage.

My keywords, descriptions, or titles or anything, is it wrong?

Thanx for your attention.

Hi..

First :
Try to put a real description in your meta description.
with this google will not understand what kind of website you have.

- Add more content in your home page.
Then Be patient.. GG takes maximum 48 Hours to show ads with the theme of your website, if it takes so long, then optimize your home page like I said.

Good luck.
