How to switch between different AdSense formats

depending on the screen resolution

[Philarmon]

Hello!

I am curious if it is possible to display various formats depending of the user's screen resolution. In particular, i want to show a 468x60 ad to the users with 800x600 resolution and the leaderboard to all others.

I mean, i know how to detect the resolution with javascript and display the ads depending on that, but then i would have to modify the AdSense code a bit (enter an "if" statement in the second part of code) what is a no no according to Google.

Is there any way?
Thanks!

I don't think you would be modifying the adsense code - you would just have 2 (original) blocks of code of which only one would be shown.

The only way to be sure is to ask Google. I've thought about doing this myself (though I can't get the CSS working), so I'd be interested to know what they say.

I would like to have an example of how this would work?
I have found scripts that detect screen resolution, but I'm not adept enough to know how to apply it to two different Google ads.

Thanks.

It's probably not screen resolution you care about, but browser window width. So something as simple as

if (window.outerWidth < 900 ¦¦ document.body.clientWidth < 900) {
# set variables for banner
} else {
# set variables for leaderboard
}

But CHECK WITH GOOGLE THAT THIS IS ALLOWED. Arguably it's within the spirit but not the letter of the rules.

I have asked Google about that and got a response today:

"While we can answer specific questions about the AdSense ad code, we are unable to provide support for general HTML or other scripting questions."

Hmm, very helpful :) Now what?
