According to OpenTable, more diners are turning to mobile devices to find information about restaurants and reservations. However, not many restaurant websites are designed for mobile use.

The online restaurant reservation service has partnered with DudaMobile, a DIY mobile website builder. Together, they have launched a free service that makes it easy for you to optimize your restaurant’s website for mobile devices.

In the second quarter of 2012, reservations booked on mobile devices accounted for 28 percent of the 28 million diners OpenTable seated in North America. Since its launch in 2008, the company has seated more than 30 million diners through mobile reservations.

If your mobile website results a blank page due to flash, or a full desktop page that isn’t formatted properly, it could be a huge turn off for potential customers. Now, anyone subscribed to used OpenTable’s software will be able to sign up to have a mobile website built for no additional cost. The only catch is that you must claim your website before February 1, 2013.

If you sign up before the deadline, you will continue to enjoy the service for free, as long as you’re an OpenTable customer. If you sign up after January 31, 2013, you will be charged an additional monthly fee for the mobile website service.
