Ahsan Sana has developed an interesting way of displaying adsense vertical ads on your website. Adsense Float allows you to place 160×600 outside of your website design by floating it to the left hand side of the page. It was designed for 120ÃƒÆ’—600, 160ÃƒÆ’—600 and 120ÃƒÆ’—240 vertical ad formats.
This is a useful option for those of you who don’t want to place large banner ads within your main design. In the latest versions Ahsan has improved the plugin so that ads do not overlap the content or scroll down the page when you you scroll.
Ahsan claims that click through rates dramatically increase when using Adsense Float though Brad from Stitch Kingdom made a good point when he noted that any increase was probably due to people trying to close the ad.
I personally prefer to keep all ads within the main content area though if you think differently I recommend you check Adsense Float out :)
