You can only set a lead capture page as your main website URL since the system is designed as a lead generation sales funnel. Customers are encouraged to opt-in to learn more information about the Helo, allowing you to capture their information and market to them in the future (improving the likelihood of them becoming a customer). The lead capture pages give minimal information for that reason. The system is designed to be a lead capture page that redirects to a tour page with further information once a lead opts-in. That is why you can only set a lead capture page as your main website URL.
