Just received an email from google saying they've rolled out a new feature for advertisers, that lets them only target ads that appear above the fold.

i was wondering how this works. i know you can pick an ad location when you set up a channel, but i doubt that google would rely on just that because it would be open to abuse.

they must have some way of checking where the ad appears. but what happens if you've got the ad code right at the bottom of your HTML, but still make it appear near the top with CSS? would google realise that the ad still appears above the fold?

maybe we should all start moving the ad code to the top of the HTML to be safe.
