How to Use Zoom: Host and Participant Guide

Zoom is the video conferencing platform that became a verb during the pandemic, and despite competition from Microsoft Teams and Google Meet, it remains the most widely used dedicated video meeting tool in the world. Most people know how to join a meeting, unmute themselves, and share a screen — but that barely scratches the surface of what the platform can do. For a broader walkthrough, our Complete Guide to Software and Apps is a good next read.

Learning to use Zoom effectively means understanding the host controls that keep meetings orderly, the collaboration features that make discussions productive, the audio/video settings that most people leave at defaults, and the advanced capabilities that most participants never discover.

Audio and video setup — get this right first

Poor audio ruins meetings more reliably than any other factor. Before any important meeting: Zoom → Settings (gear icon) → Audio → test your microphone and speaker. The microphone level should respond when you speak; the playback test should produce sound from your chosen speaker.

Noise suppression is one of the most impactful settings for home or shared office environments. Settings → Audio → Suppress background noise:

• Auto: Zoom decides dynamically — good starting point
• Low: suppresses consistent background sounds (fans, HVAC)
• Medium: reduces variable noise like typing
• High: aggressive suppression — useful in very noisy environments, but can make voice sound slightly processed

The “High” setting eliminates most keyboard typing sounds — something participants in quiet offices particularly appreciate.

Video settings: Settings → Video → check “HD” video if available, enable “Touch up my appearance” for a subtle smoothing effect, and — critically — check “Adjust for low light” if you’re in a poorly lit environment. The software brightening produces visibly better results than sitting in front of a dim background.

For genuinely good video without software processing: position a window or lamp in front of your face (not behind you), place the camera at eye level rather than looking up at a laptop screen, and use a dedicated webcam rather than a built-in laptop camera. Background blur (Settings → Video → Background & Effects) handles distracting environments without any physical setup changes.

Step-by-step meeting controls for hosts

1. Schedule correctly. Zoom app → “Schedule” → fill in name, date, time → enable “Meeting ID: Generate Automatically” (prevents reuse) → enable the Waiting Room → set a password → choose whether to require video. Schedule through the Google Calendar or Outlook Zoom add-in to create a calendar event with meeting details automatically embedded.
2. Start the meeting and manage the Waiting Room. Participants who join before you arrive wait in the Waiting Room — you see a notification at the top of the meeting screen. Click “Admit” for individuals or “Admit all” when everyone has arrived. The Waiting Room is the most important security control available — it prevents uninvited participants from entering an ongoing meeting.
3. Use the Security controls. “Security” button in the meeting toolbar → lock the meeting once all expected participants have joined (no new participants can enter after locking), control who can share their screen, enable/disable chat, remove participants.
4. Manage participant audio. “Manage Participants” → hover over any participant → “Mute” to silence a specific person. “Mute All” at the bottom silences everyone simultaneously — critical for large meetings. Uncheck “Allow participants to unmute themselves” if you want to control who speaks in a structured session.
5. Use Reactions for non-verbal communication. The Reactions button provides raise hand, thumbs up, clapping, and other emoji that appear on the participant’s video tile without interrupting the speaker. The raise hand reaction creates a visible queue so the host can manage who speaks next without chaos.
6. Share your screen correctly. “Share Screen” → choose a specific application window rather than your entire screen — this prevents participants from seeing notifications, other browser tabs, or sensitive information. “Optimize for video clip” only when sharing a video file specifically.

Breakout rooms, polling, and collaboration

Breakout rooms are the most transformative collaboration feature for workshops, training sessions, and large meetings. A meeting of 50 people is a listening session for 49 of them at any given moment; breakout rooms of 4–6 participants create genuine small-group discussion. Create them: Breakout Rooms button → choose auto-assignment (fastest) or manual → set a timer → broadcast a message to all rooms when it’s time to report back.

Settings most users never find

Beyond the basic settings, Zoom’s web portal (zoom.us → Settings) controls features not available in the desktop app:

• Enable non-verbal feedback: Settings → In Meeting (Basic) → Non-verbal feedback → On. This activates the raise hand, yes/no, slow down, and speed up reactions that participants can use without interrupting the speaker.
• Focus mode: a host-controlled mode where participants can only see the host’s video and shared content — they cannot see each other’s video, reducing distraction in training sessions. Settings → In Meeting (Advanced) → Focus Mode.
• Spotlight multiple speakers: right-click any participant’s video → “Spotlight for all” — their video fills the main view for every participant, replacing the default “active speaker” view. Use this to ensure a panelist or sign language interpreter is always visible.
• Custom waiting room: Settings → In Meeting (Advanced) → Waiting Room options → customise the waiting room with your organisation’s name and logo. Adds professional polish to client meetings.
• Authentication for meetings: require participants to be signed into a Zoom account (or a specific Zoom account domain) before joining. Settings → Security → “Only authenticated users can join.” Useful for internal meetings that should never have external guests.
• Smart Gallery: uses AI to create an individual video panel for each person in a conference room, making hybrid meetings more equitable for remote participants. Requires a Zoom Rooms setup.

Zoom vs the competition — when to use which

The question comes up regularly. A short practical guide:

• Use Zoom when: meeting with people outside your organisation (it’s the most universally compatible); when you need breakout rooms, polling, or webinar features; when high video quality is important (Zoom’s video compression is generally better than Meet’s at the same bandwidth)
• Use Microsoft Teams when: the meeting is entirely internal and you’re in a Microsoft 365 environment; you want to continue the conversation in a channel after the call; documents are being co-edited before, during, and after the meeting
• Use Google Meet when: everyone is in a Google Workspace environment; you need a quick ad-hoc video call without scheduling; you want zero installation requirements for participants

One practical Zoom habit that separates effective meeting hosts from the rest: end every meeting with a 2-minute action item review before anyone leaves. Zoom makes it easy to see the recording transcript immediately after closing (for Pro accounts), which surfaces everything discussed — but the brief in-meeting recap ensures every participant leaves knowing specifically what they’re responsible for. Good meetings create momentum; great meetings capture it.

Zoom for webinars — different from regular meetings

Zoom Webinars (a paid add-on) operates differently from Zoom Meetings and is worth understanding if you host presentations to large audiences:

• Meetings: participants are attendees who can see and interact with each other; everyone can unmute (unless muted by host); two-way communication is the default
• Webinars: attendees are view-only by default; they cannot see each other; they communicate through Q&A and chat panels; only the host and designated panelists have video. Better for large presentations where you want structured interaction rather than open discussion.

For most use cases under 100 people, a regular Zoom meeting with the Waiting Room enabled, mute-all active, and a structured Q&A period using the raise hand feature replicates most webinar functionality without the additional licence cost. Our guide on How to Use Chrome Profiles covers an adjacent issue.

Recording and transcripts — getting value after the meeting ends

Zoom’s cloud recording (Pro and above) does more than just save a video file:

• After the meeting, the cloud recording generates an automatic transcript searchable in the web portal
• Recordings are shareable via link directly from the web portal — no need to download and re-upload to another service
• The transcript identifies different speakers and timestamps every statement, making it straightforward to find specific moments in a long recording
• The Q&A and polling data from the meeting is also saved and exportable from the web portal

For teams that record regularly: establish a consistent cloud recording folder structure in the Zoom portal from the start. Recordings accumulate quickly, and the default organisation (by meeting name and date) becomes hard to navigate after a few months. Setting up a logical folder structure early — by team, by project, or by meeting type — makes the archive genuinely useful rather than a growing pile of unlabelled video files.

Mobile Zoom — what works and what doesn’t

The iOS and Android apps cover the core meeting experience well, but with some limitations worth knowing:

• Breakout rooms: participants can join and leave breakout rooms on mobile; hosts can manage them on mobile from Zoom 5.7+ but with a less complete UI than desktop
• Screen sharing on mobile: works well for sharing the phone screen; sharing a specific app is possible on iOS and Android but the workflow is different from desktop
• Background blur/virtual backgrounds: available but more CPU-intensive on older phones; if the meeting feels laggy, disable the background effect first
• Polling and Q&A as a participant: works fine on mobile
• Hosting complex meetings (breakout rooms, spotlight, co-host management): better on desktop where the full host control panel is available

Zoom’s consistent cross-platform availability — desktop, mobile, browser — is one of its key advantages for external meetings where you can’t predict what device a participant will use. The desktop app provides the best host experience; the web client (no installation required) is the most accessible for one-off participant access; the mobile app handles everything a participant needs on the go.
