Ask yourself these 9 key questions before selecting a new webcast or webinar tool:.
1. What is your webinar or webcast objective?
2. How many events will you hold per month and how many people will attend?
3. Will you generally use a phone bridge or will you be pushing sound out to attendees through their computer speakers?
4. What is your total budget for your webinars?
5. Who is your audience and what technology requirements do they have, (if any)? How familiar with webinars is your audience?
6. How familiar are your event support people and presenters with webinars?
7. How important are recordings? Will you need to provide CE credits or capture polling data from the recordings?
8. Will you be serving video, sharing applications or desktops, or require deep interactions with your audience?
9. Do you want to do a webcast or web video, with little interaction from your audience?
Note: I have listed those technologies which I have recently worked with and feel confident in recommending. Not all solutions are right for each individual application. Nor is this meant to be an exhaustive list.
