According to a recent study, iPads are driving more web traffic than iPhones—a trend that organizations should keep in mind when thinking of interesting ways to reach out to more constituents using the devices they seem to be using.
Optimizing websites for mobile consumption is a good first step. Because of the iPad’s larger screen size, it’s more conducive to reading text, viewing images on larger scale, and watching videos than the iPhone, so including this type of content on the mobile site (while keeping it simple, as is customary with mobile sites) is a good idea.
Also, if a large portion of web traffic is coming through the iPad, apps are another feature organizations can consider. Apps that may not work on the iPhone because of its small screen size may be better suited for the iPad, so you can get creative when it comes to thinking about presenting your information in a more visual way.

Be sure to consider not only the content that you put out in the Internet ether, but also how your viewers and readers are accessing that information.
