The problem is that when viewed on a mobile device, the ads overhang the content to the right side. In other words, when I load a post up on my iPhone, the 336px ad is not centred on the screen, it overhangs to the right so you only see 4/5th of the ad. This has meant my ctr is well down.
Is there a way to make the ad sit nicely in the middle when viewed on an iphone? I use Best Adsense plugin to show ads.
