Adsense - 1 Ad Group Only?

Some trick to getting more to show up?

[cabbagehead]

I've been trying to embed 2 and three adSense ad units on a single page and it doesn't seem to work. Only one ad unit ever seems to show up. Is there some trick to enabling more than one? I've seen this done on other sites! And, is there some finite limit I should keep in mind?

Thanks.

The number of ad-units that shows up depends on your content (how much, what kind of content) and the number of advertisers that is currently bidding. So if you have little content on a page or if there are only few advertisers available, Adsense might only display one unit.
Perhaps you are in a very special niche with only few advertisers?

Sorry - I guess I should define what I mean by an ad unit.

If I have a 160x600 tower it would usually have 4 ads. That entire tower is what I'm referring to as an ad unit. So, if I have a long article and I would like to stack 5 towers on top of each other, I am pasting in the AdSense javascript 3 times....yet only one tower shows up. :(

I think we are talking about the same thing.

Ouch, you mean as in the no-can-do section of the TOS?

[google.com...]
"Up to three ad units may be displayed on each Web site page"

I still think we are talking about the same thing. If you paste the Adsense javascript 3 times (wich is allowed) only one ad-unit might actually show up. It depends on your content and the number of advertisers. If there are only 2 advertisers for your niche, how could Google possibly display 3 ad-units?

If there are no ads to show , you will get nothing in the towers..

I use leaderboards, they seem to work O.K. ..At times the same ads are displayed two - three times in diffn. positions .. that fills up the space..

Ouch - I can't see it but it hurts my eyes already :)

Having loads of blocks on one page might be more detrimental than having just one and an adlinks unit. You need to consider ad blindness, and if all of the units (even if they did display ads) actually work for you.

[cabbagehead]

The idea was that I want 1 block of ads (e.g. 1 ad tower for example) to always be in frame. With a long article, the user will scroll down to read the article and then 75% of the time spent reading they will see no ads!

It seems that the reason more ads aren't showing is because I"m in my dev environment (e.g. localhost). as soon as I deployed to Stage the other ad units started to show. :)

You could always use CSS to keep that one ad block on the screen at all times.

Actually, I just setup my own default ad banner to display when ads aren't available and so now I can see where things should be during Dev. So, I guess I'm good to go!

Thanks.
