With the growth in popularity of high-end mobile phones with full (HTML) Internet browsers, like the iPhone and phones running Android, advertisers are increasingly extending their campaigns to mobile devices. Because these devices offer a rich content experience similar to desktop, advertising on them is a natural extension for many advertisers.

Today we’re launching a new feature for AdSense mobile publishers that will allow you to take advantage of the high-end mobile phone browsing experience. This feature offers publishers the ability to run larger AdSense ads visible on high-end phones. Before this launch, AdSense mobile publishers were only eligible to serve smaller text and image ads on their website content.

We’ve done this by introducing a new JavaScript snippet that is easy to implement and specifically optimized for mobile to reduce latency on high-end mobile phones. Furthermore, this new snippet will allow publishers to select additional ad unit sizes from common AdSense formats.

However, if you’re targeting all mobile devices, or if you’re unable to make changes to your website, you don’t have to update your AdSense code in order to enable larger AdSense ads to show on high-end devices. We’ll automatically detect if the user is browsing with a high-end phone, and instead of serving a smaller mobile WAP ad, we’ll return a larger ad optimized for high-end mobile devices.
