This happens when if your site is new..or you just put ad in a page..it will take around 24 hrs to display sometimes.
Can't you see any ads at all? It sometimes happens, hit reload a few times and check it the ads appear.
I could see the ads too....well lets discuss this further a bit why you could not see your ads besides the inputs above by others member of this forum - if you have more than 3 ads campaign on one page, then you will only see these three. the rest will not appear. - if you have copied wrongly the ads code, then it will not show either. Is all the places where you pasted the ad codes does not show adsense ads, or is it certain places only? Check them... - make sure your check your email... did Google just banned you? I think not as I just saw your ads.. Learn online business models and how to start them on my site....
Sorry, but your answer makes no sense whatsoever. I have several sites. All have adsense. None are against the rules. I can't see the Adsense ads on my own sites ever. I can go to someone else's computer and see them immediately. Even if I put up a new site, the ads appear instantly. Doesn't matter if the site is new or not. My Firefox pop-up blocker is disabled. I also can't see my ads in IE. This is a widespread problem that so far has no answer. The problem is that we can't see if our ads fit the page correctly and if the ads are targeted to our site. Everything has to be done blindly and that's no good.
Nope, wrong answer. I can't see my own ads at all but I can go to my neighbor's computer and see all my ads with no problem. In the world of Google adsense, the term "stale ad" doesn't even make sense. And no, refreshing is not the answer.
