Only 1 Ad Unit out of Three is Showing

What Would Cause that to Happen?

[Ghazz]

I just got approved last night for one of my sites. I have a vertical 160x600 that shows up fine. I have another at the top of the page and at the bottom, but neither are showing up. Is this possily because I just got accepted last night? If thats the case, why does the ad on the left show up, but not on top and bottom of page? Any advice would be appriciated. The code is correct, doesnt have anything to do with that.

It could be a lack of good inventory for the page. As I understand it, AdSense will fill one adblock with ads that are at least a broad match, but not additional blocks. It will only fill additional blocks if there are close matches to the keywords on your page.

Targeting MAY improve and you may start seeing more ads, but it's possible you would be better off with only one adblock. Then your visitors see fewer ads, and they only see the best-paying.

Sometimes less is more.

That's weird, the topics on my page are pretty popular, I would think they would have plenty of adds for it. But okay, I guess that makes sense.

I also see different ads when the page is refreshed, so there seems to be plenty...

What you are seeing more of are the broadly-matched ads. AdSense can be very specific.

Give it a few days, if you like, to see if more ads show up. That can happen. But you might be better off with just one adblock, as I said before.
