How to Choose a Webinar Topic: 5 Tips to Find Ideas

Key takeaways:

• The best webinar topics solve one specific problem for one clear audience, and they come from real questions rather than guesswork.

• Questions and chat messages from earlier webinars are the richest source: on average 31% of viewers interact during a webinar, and every question is a possible next topic.

• The webinar's purpose shapes the topic. Internal sessions keep 82% of their viewing time on average, while sales webinars hold 60%, so focused topics matter most when the stakes are highest.

The strongest webinar topics start from a problem the audience is dealing with right now, framed for a group of people specific enough to recognize themselves in the title. The quickest way to find one is to collect real questions from customers, colleagues and past webinars, then pick the one with the clearest problem and the strongest fit with the webinar's goal.

That sounds simple, yet topic choice is where many webinars quietly lose their audience before the first slide. A broad or vague topic gets fewer sign-ups and more early drop-offs, while a sharp one does half the promotion work on its own. Below are five reliable tips for finding ideas, followed by a quick check to make sure a topic will hold up.

What makes a good webinar topic?

Strong topics tend to share four traits, whatever the webinar type:

• A specific problem. "Email marketing" is a subject. "How to write a reminder email people actually open" is a topic.

• A clear audience. The title should tell a new HR manager, a SaaS marketer or a first-year teacher that this session is meant for them.

• A fit with the purpose. A training session, a product demo and a community event each need a different kind of topic (more on that below).

• A promise the content can keep. If the title promises five steps, the session delivers five steps, not three steps and a sales pitch.

Purpose matters more than it might seem. According to the WebinarGeek Benchmark Report 2027, viewers of internal communication webinars watch 82% of the session on average and customer onboarding sessions hold 80%, while sales and conversion webinars hold around 60%. When attendance is voluntary and attention is contested, a tightly focused topic is what keeps people watching.

5 tips to find webinar topic ideas

1. Ask the audience and the people who talk to them

The people a webinar is for usually know exactly what they are stuck on. A short survey of three to five questions, sent through a newsletter, a customer email or a LinkedIn post, is enough to surface recurring problems. Tools such as Google Forms or SurveyMonkey make this a ten-minute job. Open questions tend to work better than multiple choice here. "What is the one thing about X that takes you the most time?" brings in language that can later be reused almost word for word in the title and registration page.

Support, customer success and sales teams are a shortcut to the same insight, since they hear the same questions every week. A quick conversation, or a look at the most common support tickets, shows which topics cause confusion. This works just as well internally: HR and IT teams know which policies and tools generate the most questions from colleagues.

2. Mine questions from past webinars

Every webinar produces a list of questions, and most of them never get a full answer in the time available. On average, 31% of viewers interact during a session through chat, questions, polls or upvotes, so even a mid-sized webinar generates plenty of material. Questions that come up repeatedly, or that collect many upvotes, are strong candidates for a dedicated follow-up session.

Reviewing the chat and question list after each session, and noting the ones that deserve more time, builds a ready-made list of future topics.

3. Check blog and webinar analytics

The content that already performs well is a strong signal of what the audience wants more of. Look at the most-read blog posts, the most-downloaded resources and the pages with the longest time on page. For webinars, compare registrations, live attendance and average watch time per session. A topic that kept people watching to the end is worth revisiting from a new angle or at a deeper level.

Webinar analytics also show where viewers dropped off, which often points to the part of a topic that deserves its own session.

4. Follow search data and online conversations

Search engines reveal the exact questions people type when they have a problem. Search the core subject on Google and note the "People also ask" box and related searches at the bottom of the page. Free tools such as Google Trends show whether interest in a subject is rising or fading, and AnswerThePublic groups questions by theme. The phrasing found here is useful twice: once to choose the topic, and again to write a title that matches how people actually search.

LinkedIn comments, Reddit threads, Slack communities and industry forums add the context search data lacks. Threads where people disagree or ask for help signal a topic with real tension, and timely subjects such as a new regulation, a tool change or an industry report tend to attract registrations because people want help making sense of them quickly. To keep track without checking every channel daily, set up Google Alerts for key terms in the field.

5. Brainstorm with AI, then validate

AI assistants are good at turning a broad subject into a long list of angles. A prompt such as "List 20 webinar topics for [audience] who struggle with [problem], each with a specific promise" gives a useful starting point in seconds. The catch is that AI suggests what sounds plausible, not what this particular audience needs, so treat the list as raw material and check it against the tips above.

How do I know a webinar topic will work?

Before committing to a date, run the topic through a few quick checks:

• Narrow it down. Start wide, then cut until the topic fits comfortably in the session length. If the outline needs more than three or four main sections, the topic is probably two webinars.

• Write the title first. If a clear, specific title with a concrete promise does not come easily, the topic is not sharp enough yet.

• Let the audience vote. Share a shortlist of two or three options in a poll, a newsletter or a post at the end of a previous webinar. The winner comes with a group of people already interested.

• Check the competition. Search the topic and see what is already out there. An existing webinar or guide is fine, as long as the new session offers a different angle, more depth or a more specific audience.

One note on early signals: low sign-up numbers two weeks out are not necessarily a bad sign. The Benchmark Report 2027 shows that almost two thirds of registrants sign up in the final week before a webinar, and 44% register between one and seven days ahead. Judge a topic on final registrations and attendance, not on the first few days of promotion.

Match the topic to the webinar's purpose

The same subject can become very different webinars depending on the goal. A topic about onboarding software, for example, could be a training session for new customers, a product demo for prospects or a Q&A for existing users. Deciding the purpose first makes it much easier to choose the right angle, length and format.

Frequently asked questions about choosing a webinar topic

How do I choose a webinar topic?

Start with real questions from the audience, collected through surveys, past webinar Q&A, support teams or search data. Pick the question that describes a specific problem for a clear group of people, check that it fits the purpose of the webinar, and test it by writing a concrete title. If the title is easy to write and easy to understand, the topic is usually ready.

How specific should a webinar topic be?

Specific enough to fit the session length without rushing. A 45 to 60 minute webinar typically covers one problem in three or four main sections. "Social media marketing" is too broad, while "How to plan a month of LinkedIn posts in one afternoon" gives both the presenter and the audience a clear goal.

Should I reuse a topic that worked before?

Yes, as long as there is something new to add. A topic that drew strong attendance is proof of demand, so a follow-up with a deeper level, a different audience or updated examples often performs well. Recordings of the original can also keep working on demand: in the Benchmark Report 2027, 11% of all sign-ups watched the replay.
