I am a inspirational speaker living with type one diabetes. My show, The Sugar Free Shawn Show, is an on line show that serves the diabetes community of healthcare providers and patients.
Advertisers are going to want to see stats: page views and any demographics about the viewers like where they are coming from so there can possibly be targeting. Anything that can be see as a media extension, like social media follower numbers would help you prove to advertisers why they might want to spend money with your show. If you can package that together in an easily digestible way, that is easier.
Creating a beautiful visual deck that shows the branding of the company, prior successes and of course core numbers on who your target audience is, how broad the reach is and how that creates benefit for the sponsor is key!
