I somehow got impressions all last month (I didn't even think I even have adsense running anywhere, so who knows how I earned $1.19) anyrate, when I went on a couple days ago since I finally bought some sites I wanted to put Adsense on (cause I rarely use it anyways) and when I placed the ads, they just show up white boxes (no ads). I checked and didn't see any messages saying I was banned or anything (not even a notice saying I'm inactive or whatever). So any idea what it could be?
It may be because Google hasn't found any ads relevant to your ads yet. Give it some time to let it crawl your site to determine what niche you're in... they should be showing relevant ads soon.
may be its site ban, or account ban, or they didnt find an ad to put, or your page has some illegal wordings on it. or it is because you put more than allowed number of adds.
Ok finally got a response from Google, and they said that they don't have the time to figure it out so they suggested I look at some forums and a bunch of useless links.
