Listing Distribution is a continual process that maintains and builds your web presence over time. Once the data aggregators have your correct business information, the rate at which sites reference this information varies. To ensure the widest span of information and amount of listings created, Listing Distribution needs to be activated for an extended period of time.
Even if your business information is correct, listings can be eroded over time by user-generated content and other incorrect data. As long as your subscription is active, Listing Distribution refreshes your information with the data aggregators every week. Without this, there is a risk of allowing the current public data to change all of the value already established.
