A webinar is an interactive online event that is viewed over the web. Webinars can be delivered by one presenter or they may be hosted and co-presented. They typically focus on a topic for usually no more than an hour.
The webinar can include video of the presenter talking, slideshows, or other visual elements. The presentation is usually followed by a Q&A session, during which time the audience can ask questions. You may also want to consider an offer or bonus materials at the end to help keep people watching and generate leads.
