Webinar topic ideas
Webinars are the easiest registration in marketing, 75% of buyers will sign up for one, the top of any gated format per Demand Gen Report's 2024 survey, and the hardest room to fill: only a third to half of registrants actually show up, per Livestorm's and Goldcast's benchmarks. The topic decides the gap, because people attend problems, not subjects. Below are 55 webinar topic ideas that lead naturally into an offer, plus a free generator and the checklist.
Runs in your browser, free, no signup. Pick the topic that sits one step upstream of your offer and promises a result inside the hour.
Webinar topic ideas, grouped by shape
Each idea below is a topic shape with a worked example: keep the shape, swap in your subject, and read the note for why the shape fills seats. One rule sits over the list: a webinar is a class that sells, so every topic here promises a specific problem solved and leaves your offer standing one step downstream as the obvious way to go further.

Registrations measure the promise; attendance measures whether people believed it. Five checks before you schedule.
- Promise a problem solved, not a subject covered. Registration is the easy part, Demand Gen Report's 2024 survey found webinars are the format buyers will most readily register for, at 75%, but only a third to half of registrants attend (Goldcast 33%, Livestorm 51.3%, ON24 57%). A topic shaped like 'fix this specific thing in an hour' survives the gap; a topic shaped like a conference track doesn't.
- Sit one step upstream of your offer. The webinar teaches the decision or the first mile; the offer handles the rest of the road. The research backs teaching as selling: a Conductor study found consumers 131% more likely to buy right after consuming a brand's educational content, and Edelman-LinkedIn found 75% of decision-makers research products they weren't considering after strong thought leadership. Pick the topic whose natural last slide is your offer.
- Design for the first 26 minutes. Livestorm's 2026 benchmarks put average watch time at 26 minutes of a 68-minute session. Front-load the promised payoff, keep one thread instead of seven tips, and use the room: Livestorm's data shows the average webinar runs polls and fields about 20 questions, and a session that asks things holds people longer than a slideshow that recites things.
- Let the topic do the promoting. Livestorm's data shows 49.6% of registrations arrive in the final week, so a long runway rescues nothing. Two to three weeks of promotion is plenty when the topic names its audience; and pair the webinar with a lead magnet on the same problem so the registration page converts twice.
- Plan the replay before you go live. Nearly half of ON24's webinar attendance is on-demand, and Livestorm found ungated replays average almost four times the views of gated ones. Choose evergreen topics that replay well, cut the recording into clips, and let one live hour feed a month of content. The pitch works after the event too: ON24 recorded a threefold rise in meetings booked during webinars.
The show-up test
Two webinars promoted to the same list, same week.
The vague topic actually won registrations: 'everything' sounds generous, and signing up costs nothing. Then the week passed, and only the specific promise survived the calendar. That's the benchmark spread in miniature, show-up rates run from 33% to 57% across Goldcast's, Livestorm's, and ON24's data, and the topic is the variable you control. A webinar row of empty seats isn't a promotion failure; it's a promise nobody needed kept.
