I've tested an enormous variety of layouts using two and three AdSense units. The layouts with three AdSense units consistently outperform the layouts with two AdSense units.
I have not seen a niche with a shortage of of advertisers in quite some time. If there were a real shortage of advertisers, the third ad block might not get filled with ads.
One mistake that often trips people up when adding multiple ad units is making sure that the ad code in the HTML source is in the best order. For example, if you have a simple layout with a content ad and a footer ad and you add a banner ad to the top of the page, you can completely screw your CPM. Why? Because if you are not very careful, the simple thing to do is to put the top banner ad code first in the HTML source. This means that AdSense will place the best performing ads in the banner spot -- which is a low-CTR spot. Instead, you want to use CSS to make sure that the best-performing ads appear in the highest-CTR slot -- the center ad. You can still have a top banner ad, you just need to make sure it loads last in the HTML source.
Thanks for answering Will, I'm trying to work this out in the context of my current pet website, Ronda Today, a resource for tourists and expat residents, which is a standard 2 column design with header, sidebar/content, footer layout. At present I've only got AdSense on the pages that seem to get the most search engine traffic, and I've only got a single large rectangle.
The AdSense on the pages that have it is inserted into a div after the page header, and before the content, and wraps around the content using CSS, and is first in the HTML source, for example Using British Electrical Appliances in Ronda, Spain
If I add a banner ad to the page I simply add the code at the bottom of the content, and reposition to the header using CSS which is easy, and this would be second in the HTML source.
But where do I put a third block of Adsense, if I put it in the sidebar, it will be either first or third in the HTML source, but I'm not sure if this is a good location anyway. Your thoughts?
That's a nice web site. I just linked it from Expat Spain.
You'll get better performance from the 336x280 rectangle than from the 250x250 square.
You will also see significantly improved CPM by adding a 336x280 at the bottom of the article. Or, if you're sharp, putting them both inside the content.
Adding another column with a skyscraper will give you another small bump, but only a small one. It may not even be worth the effort for you. A banner ad in the header would be even less of a bump.
Hmmm... now I'm thinking... I want more in-content ads on my own pages. :D
My trouble is that my pages are variable length, and some are just too short to hold three in-content ads.
Thank you very much, I've bookmarked (delicious) your page so I can return to it later.
That is easy to do. I'm using RapidWeaver with the stacks plugin so I can add two AdSense blocks easily enough, not sure if I have enough content on all the pages, might have to do some more writing. When you say inside the content, what is a good position, say after the first paragraph (above the fold) and maybe before the penultimate paragragh?

So on a longer page, like for example my Ronda history page, maybe throw in three of the big rectangles?
