Your best source of new members, is current members.
They are connected within the industry, and they already know, like and trust you.
Furthermore; people want to buy, but they don’t want to be sold to.
So what your members say about you, to a prospective business owner/manager, will always be more valuable than what you say about yourself.
Your job is to both arm existing members with the language to use to communicate the value of a membership, and provide an incentive to introduce new businesses to your Destination Marketing Organisation.
