Now that sounds like a good idea, and I'm all in favor of what he earns more. It is the second part of the process that bothers me: When I was out the other ads, one ad in Google expands to fill the remaining space that remains.
Because it breaks the golden rules of successful Adsense statement that the ads blend into the page. Google provides a complete set of tools that you can use to make your ads match the rest of the page: If you have already used and should be used, and then your hard work will be ruined. Same applies to any pictures or anything else that you can be placed next to the ad units to capture the reader's eye, without notes, they are pulled into one of the ads.
I may be wrong, and Google say they only need to use this system when they see it increases CTR. But at the same time, I think it's a good idea to keep a close eye on your site, as well as your stats to make sure that all of your pages look the way you want to look, and not so, Google makes it look.
You can read about this new change in the Internet. If you have not already checked it out, and I highly recommend it. It's a great resource. You not only get the news, but unlike a blog about (which is definitely worth reading too) you can be sure that any changes that we know you read the actual article here. Any rumors and stories are not. Facts directly from Google.
