Ads not coming up on main page

Showing on all pages except main page

[isthebest]

Everything was working fine till today,

I got one 120x240 vertical ad on my sidebar. Suddenly, the ads are showing on all pages except the index.

I can see the Google ads perfectly fine on

http://example.com/top.php
http://example.com/submit.php

but

http://example.com/index.php

is the only page that is without Google ads and only PSA.

Why is this happening? I didn't touch anything prior to this.

I hope you guys can understand what I'm trying to put across.

Thanks.

Maybe crawler found some "stop word", like terrorism, etc.

Could it have anything to do with the fact that my website actually encourages refreshing over and over again?

I begun to see the same a couple of days ago.

www.mysite.com/index.php shows adds SOMETIMES.
www.mysites.com shows ONLY PSAs.

I hadn't done any changes to the home page when this happened. Had since but no change.

By the way my site if very season deppendent and the main season just finished. I thought that might be the case, but plenty of adds are showing in all other pages.

What do you mean by "my website actually encourages refreshing over and over again"? Are you forcing page refresh every NNN seconds/minutes? If yes then such behavior may get you banned for generating invalid impressions.

No, it's the nature of the web site where my visitors will want to refresh over and over again.

Is that the problem here? I've seen another similar website and it's doing fine with adsense.
