Cassie Roberts from Saffire discusses strategies for maximizing revenue through online sales and ecommerce. She emphasizes that while only 1-2% of website visitors typically make purchases, various tactics can improve conversion rates. These include clear calls to action, allowing purchases from any page including photo galleries, detailed product information, early merchandising announcements, bundling related items, mobile responsiveness, and utilizing email marketing which has high open and purchase rates. She encourages attendees to think creatively about new ways to sell online and leverage various channels to reach more potential customers.
