Is it Ok To Display Google Adsense Ads inside Fix Div?
Is it ok to put Google Adsense ads on a Fix Div in My website or is it illegal?
As far as I know You can't put google ads inside fix div. This is what google says.
Drawing unnatural attention to ads includes placing Google ads in a floating box script that causes the ad to appear in a “sticky" position on the page as the user scrolls down. This type of ad implementation is not permitted.
