Keynote speeches typically range from 30 to 90 minutes, with the duration determined by the speaker’s expertise, the event’s agenda, and audience preferences. Keynote speeches often include a combination of inspirational stories, practical insights, and actionable advice tailored to the event’s theme or objectives.
The scale of the event and audience size can indeed impact a speaker’s fee. Larger events with a broader reach or higher attendance may command higher fees due to increased exposure and demand. Conversely, smaller events or niche audiences may offer opportunities for more flexible pricing arrangements.
