How to conduct a large online meeting for 300+ people

August 11, 2025

Online meetings for a large audience can have many purposes. However, they are mainly organized for education and training and have particular characteristics:

• Participants are strangers to each other
• Participants are often muted by default
• Controlled participation via raised hands, chat, or Q&A
• Carefully planned with a specific agenda
• Limited direct interaction
• One-to-many communication (speaker to audience)
• Pre-event registration or invitations
• Post-meetings follow-ups and meeting recording

Thus, for every large meeting you are going to host, you need to create a detailed plan and checklist. Unlike meetings for small teams, large online conferences require thorough planning, perfect timing, and clear goals.

Checklist for large online meeting

Any large meeting has three stages: the preparation stage, the meeting itself, and the after-meeting follow-up.

The planning stage is very important. It starts several weeks or even months ahead and should include the following:

• Thorough planning: meeting goals and agenda, the tools to support a large number of participants, meeting format, generating the invitation link, and registration page setup.
• Team preparation: decide who is going to be the host, moderator, presenter, responsible for technical support, and user assistance.
• Technical setup: presentation creation, test cameras, and collaboration features such as chat or screen sharing.
• Rehearsal session: when all materials are ready, test everything with your team to avoid confusion and be prepared to face various challenges. Ensure that your microphones are working properly and test your recording settings.
• Pre-meeting reminders: several days before the meeting, send attendees reminders, share instructions, technical, and etiquette tips.

On the day of the meeting, organizational and technical issues should not distract you, as they should have been taken care of during the preparation stage. Thus, here is the checklist for the meeting day:

• Wake up in a good mood and avoid stress. The meeting itself, especially the large one, is a big stress. Thus, there should be as few irritating situations as possible. Just stay calm and organized. This will help you address unexpected situations faster during the meeting and keep everything under control.
• Run final check 30-60 minutes before the meeting. Just make sure everything is up and running, you can easily connect, and your speakers and microphone work fine.
• Start your meeting with a welcome message, introduce yourself and speakers, explain how to use chat or Q&A, provide clear instructions about interactions, and start the recording.
• Stick to the agenda and timing. It is important to have everything on time and according to the announced agenda.
• Monitor chat and Q&A box for questions or issues from participants.

The final stage includes not only thank-you words, but also past-meeting communication:

• End the sessions smoothly and thank attendees and assistants.
• Share meeting materials: slides of your presentation and recording link or file.
• Feedback and follow-up. Ask for feedback and send after-meeting follow-up emails that include a meeting summary, thank-you words, and meeting materials.
• Review analytics of attendance and engagement.

Tips for working with a large audience

You will never know the tech skills of your attendees. Still, you can make the meeting engaging, interesting, and easy to participate in. You can get the most out of your conferencing tool: use screen sharing, polls, chat rooms, and file sharing options. All these small from the first sight things, make the meeting unique and engaging.

The meeting is not only the work of the speakers, it's the work of the whole team. While the presenter is speaking, co-hosts are answering questions in chats and warming up the audience with polls.

A detailed meeting plan, a strong team, and a reliable conferencing tool are everything you need to make your large online meeting a success.
