http://www.rumbleradio.net/new/ The ad on the right is taking up space...but it's not showing up. I just implemented them, so it might take a couple minutes? Who knows?
Why is the page language de? Shouldn't it be en. That might be the problem. Also noticed typo in your keywords, and everyone of the nav links come back a 404 (not found) except for your sponsers. You need to make all those nav links work before you worry about the ads. It's not a new trick to have nonworking nav links and forcing the user to click an ad out of frustration will get you banned pretty quickly.
Great points corinaw. The OP's site is a great example of a site with worthless content. Why would anybody want to revisit a site like that? All the links go to the same page. Ridiculous. Stop being lazy and write content.
Second and third ad units can sometimes day a day or two to show up, just one of those weird AdSense quirks.
Ok, I edited things up a little bit. The links are dead because I'm not ready to go live with the site yet... However, I just wanted to get my main template setup.
Adsense needs content, if it's often updated and fresh it would be better. NewToAllThis is right: you have to start writing content.
The others are right- You are very slim on content. I can't read the ad topic as it is in another language, so I can't tell **what** subject google thinks your site is about. Looking at your meta keywords, (wrestling related) vs on page text, there is a disconnect as there is not even one mention of wrestling on the visible text. So if you want wrestling ads, make sure the visible text is there for the user- If I could not determine the topic, how do you think google will figure it out? Another issue is when my ads have been messed up, I've noticed after I fix them the google media bot can take a week or so to come back and start serving approp ads. Which is why your ad is still in another language. To see if your change corrects the problem immediately, save that test file to a new name on your server and you will force a new refresh of ads being delivered. I hope that helps.
