down to one ad block ???

I've recently created a new site and a couple of new pages on old sites and have noticed that if I put more than one ad block on the page only the first one shows up. It's almost as if google doesn't have enough ads to fill in the other ad block, but if you check shawn's sandbox page it is full of ads. Has anyone else experienced this recently? I'd prefer to have two ad blocks on each site.

 

I switched back to one ad block just because the ctr and the return was higher with only one block than with two or three.

 

I've also reverted to one ad block and I'm seeing similar results to mopacfan.

In my case my first ad was a single ad block, and I had a 4 ad banner at the bottom. Often the 4 ad banner didn't show (due to the single ad block). After removing the single block 4 ads turned up in the banner.

 

That happens a lot, sometimes if you refresh, then the other ad blocks show up. I have 2 on most of my site, but since the competition is lower for the keywords, maybe i should just have one block and see if my epc goes up.

 

CTR and CPM can easily get lower if you have more than one ad block, purely because each page view now counts as two or three ad impressions, instead of just one ad impression.

But, what you should really worry about is your average earnings (or daily earning). As long as these go up, the rest of the stats should not make any difference.

I have recently (yesterday, in fact) started experimenting with more than one ad block (even three) with my site on pages that have a lot of text and Google seems to be able to find enough spots to fill the blocks.

In your case, it could be possible that Google either doesn't have enough ads to fill the spots due to your specific market category OR there isn't enough content on your pages for Google to find relevant ads for your page.

 

is this true only when the ads do show up or when public service ads show up as well? in other words, do public ads (or alternate url displays) count as ad impressions?

 

Public service ads do I beleive, and clicks on them do to, you just don't get paid for them.

btw, this thread made me revisit my pages with more than one block (there is only one page actually). looking closer i realized that adding a second block made my epc go down significantly. so i removed the second block. more than half the time my sencond block would display public service ads anyway
