Basics

What is a webinar?

A plain-English definition of the webinar, with examples and the main types, so you know exactly what the format is and when to reach for it.

The short answer
A webinaris a live or pre-recorded online presentation, broadcast over the internet, where one or a few presenters teach, demonstrate, or sell to an audience in real time. The audience watches the screen and interacts through chat, polls, and Q&A rather than appearing on camera. Businesses use webinars to generate leads, sell products, demo software, and onboard customers.

How a webinar works

A webinar follows a simple path. You publish a registration page where people trade their email for a seat. They get reminder emails leading up to the event. At the scheduled time (or, for an evergreen webinar, whenever they register) they join a room, watch a presentation built around slides or a live demo, and interact through chat and polls. Near the end, the presenter usually makes an offer or points the audience to a clear next step.

The reason the format works is leverage. One presenter can teach, build trust, handle objections, and sell to hundreds of people in a single sitting. That is the whole funnel, compressed into one hour.

The main types of webinars

Not all webinars do the same job. These are the formats you will run most often, and what each one is best for.

Live vs evergreen (automated) webinars

A live webinarhappens once, at a set time, with a real audience. It converts well because the energy and the Q&A are real, but it does not scale on its own. An evergreen webinar is a recorded session played on a schedule, so a new registrant can attend almost any time. Honest evergreen still uses real per-registrant deadlines and labels the recording as a replay; it never pretends a recording is live.

How is a webinar different from a meeting?

A video meeting is many-to-many and conversational: everyone can talk and share video. A webinar is one-to-many and presentation-led: a small number of presenters broadcast, and the audience participates through chat, reactions, polls, and Q&A. That structure is what lets a webinar hold a large room and still feel interactive.

Why businesses use webinars

Four jobs come up again and again: generating qualified leads, selling courses and coaching and services, demonstrating software to drive trials, and onboarding new customers to first value. In every case the webinar is doing the same thing: earning attention, building belief, and pointing to one clear next step.

What you need to run one

At minimum: a clear promise and topic, a registration page, reminder emails, a room to present in (live or evergreen), and a single call to action. You can assemble that from separate tools, or run the whole thing in one place with an all-in-one webinar platform that bundles the registration page, reminders, the live or evergreen room, and checkout together. Our step-by-step hosting guide walks through each piece.

Frequently asked

Most selling webinars run 45 to 90 minutes: roughly 5 to 10 minutes of intro, 30 to 50 minutes of teaching, and 15 to 20 minutes for the offer and live Q&A. Shorter product demos can land in 20 to 30 minutes.
Vendor benchmark reports place live show-up rates roughly in the 35 to 50 percent band of registrants for a general audience, and higher for warm or B2B lists. A strong reminder cadence is the single biggest lever for moving that number.
Yes. A webinar gives you synchronous attention and the chance to shift beliefs and handle objections live, which is why it still converts better than most one-way formats for considered purchases. The format matters less than the structure behind it.
A meeting is many-to-many and conversational. A webinar is one-to-many and presentation-led: one or a few presenters broadcast to an audience that interacts through chat, polls, and Q&A rather than on camera.
You can start free with tools you already have. Dedicated platforms that bundle the registration page, reminders, live or evergreen room, and checkout (such as Webinly) are designed to be more affordable than stitching four separate tools together.
