IDEA: Advertise to those waiting in your lobby with plenty of new product literature and flyers.
Give visitors literature in the lobby while they wait. Advertise new products, answer questions about problems they may incur and how to solve those problems. Have brochures describing all of the benefits of the company products or services and have plenty of fully answered FAQs to read and take with them.
Put a ‘call to action’ next to the literature, “Take these today and call us for a free quote!”
