Only one ad block allowed?

[cedmond]

I thought I used to be able to do this but now I can't. I have a wid skyscraper on the side of my blog and when I add a half-banner or something small to be display with each post, the skyscraper goes away? Is there something I'm missing here?

I am no expert, but my common sense tells me that your page you are displaying these ads on does not have enough content on it to draw in the ads based on the keywords on the page. I may be wrong, but that's what I have noticed on some pages of mine that are limited in content.

My site is content oriented, so for the most part I don't have problems displaying multiple ad sections, but at times on particular pages only 1 or 2 of the ad spaces will be filled correctly. But when they do not display I have a nice replacement ad to display.

I see this happening on my site starting today. I have a ton of content, but only one ad is showing per page.

I find it odd because I never had this problem before.

It may be advertisers turning off content ads. This means no advertisers want to show ads on anything but search results. This is due, at least in part, from scraper sites. There are several threads around webmasterworld.com where advertisers talk about turning off content ads because of this problem.

Did you set an alternative color to your ads such as white if Google could not find enough ads? This may be why they seem to dissapear.

I am new to this forum so apologies if I get it wrong.
I run several sites and have exactly the same problem. I have a skyscraper on the right. Add another ad block anywhere and that one disappears.
The pages are content heavy - more than 1,000 words each - and deal with travel places which attract heavy destination-specific advertising. Depending on the search term you use some of the pages have the top ranking in Google.
I therefore doubt that the reason the advertisements are not appearing is due to a lack of attraction. It something I have screwed up in coding the pages - I am not a total beginner but close.
The link provided in an earlier answer clarifies the Google position on this - it is all for multiple ads up to a maximum of three on a site - but it does not address my problem. Any suggestions, advice, pointers received with pathetic gratitude. I have been struggling with this for weeks.

the previous link was helpful but it seems more like enabling one, turns off the other. If a put in the per post half banner, the wide skyscraper disappears. No matter how I change the colors on either one, if the per post ads are there, the skyscraper is gone.

There seriously appears to be some mystery here. I have tried taking out any Javascript in my site in case that was causing the problem but the result is still the same. I had a friend of mine, much more experienced than I, have a go and he got nowhere.

found out what the problem was. it was exactly what the previously mentioned link suggested it was. were i was putting the half banner was inside the code that dynamicall displays the posts on my blog. it would display ads for the first 3 posts, thus hitting the three ad limit. Moving the ad out of the code to dynamically show the posts, fixed the issue...for me at least :)
