3. Don’t make them long. It is important to be considerate of your audience when deciding how long to host your lunch & learns. The general rule of thumb is 30-60 minutes, but again, it depends on the type of audience. For example, if you are targeting busy business professionals, then 30-45 minutes may be sufficient. Take about five minutes to introduce yourself, your company, and the topic of the webinar. This will give attendees a few extra minutes to join if they are running late. The next 20-30 minutes should be used for your presentation. Don’t forget to dedicate a few minutes at the end of the presentation for a question and answer session and lead capture. Generally speaking, webinars should last no longer than one hour. This gives you enough time to present and interact with the audience without them becoming bored and disengaged.
