The
mobileUrl property is provided for specific situations in which data consumers need to determine whether one of several provided URLs is a dedicated 'mobile site'.
To discourage over-use, and reflecting intial usecases, the property is expected only on
Product and
Offer, rather than
Thing. The general trend in web technology is towards
responsive design in which content can be flexibly adapted to a wide range of browsing environments. Pages and sites referenced with the long-established
url property should ideally also be usable on a wide variety of devices, including mobile phones. In most cases, it would be pointless and counter productive to attempt to update all
url markup to use
mobileUrl for more mobile-oriented pages. The property is intended for the case when items (primarily
Product and
Offer) have extra URLs hosted on an additional "mobile site" alongside the main one. It should not be taken as an endorsement of this publication style.
