This is a recent change we made to the submission form. Some of our local search partners require the business description to meet a certain character limit. The business listing you published before has been distributed successfully to our network of local partners. However, if you want to make changes to your business listing and your business description does not meet the required character limit, you will be required to append it. As always, your latest changes will be syndicated to our local search partners, including a longer and, hopefully, more informative description of your business. Another benefit of providing a longer business description is to further optimize your business listing for the search engines that look for rich content that includes pertinent keywords.
