Almost Nobody Runs a Webinar in July. 43% of Them Land Between Now and November.

Summer is the emptiest room in webinar marketing. Only 5% of webinars are hosted during the summer months of July and August. Almost everyone else is fighting over the same two windows.

That's the finding buried in Univid's 2026 webinar report, published in the last couple of weeks. Around 43% of webinars are hosted in spring (March–May), and 43% in fall (September–November).

Do the math on your own launch calendar. If you're planning a live webinar between now and Thanksgiving, you are sharing the inbox with nearly half the year's total volume, compressed into about twelve weeks.

The report's own warning is the interesting part

Vendors usually publish stats that flatter the behaviour they're measuring. Univid didn't. The report notes that when you look at attendance rates, popular also means a lot of competition for the audience's attention.

That's the tension nobody building a fall funnel wants to sit with. September through November feels like the serious season — budgets are alive, people are back at their desks, the out-of-office replies have stopped. It's also when every competitor, every adjacent creator and every SaaS company in your niche reached the same conclusion.

The registration page is not the bottleneck. The calendar slot is.

What actually converts once you get them in the room

Length matters more than most creators assume. Webinars running 60 minutes converted highest on attendee-to-CTA-click at 26%, with 45-minute sessions close behind at 25%.

That five-minute-per-percentage-point trade is worth noticing. You get essentially the same CTA performance from a session that asks for a quarter less of someone's afternoon — which, in a month where their calendar is already stacked with other people's webinars, is a real acquisition advantage.

Most hosts are still defaulting to the long version. Most webinars run between 30 and 60 minutes, and the single most popular length is 60 minutes, at 37% of all sessions.

For context on what "good" looks like at the offer: Univid's data puts the average CTA button conversion rate in webinars at 22%, and the platform cites the same 22% figure as the average across its dataset. A 45-minute session landing 25% is above the line, not a fantasy number.

Attendance holds up better than the doom narrative suggests. Across the 2,000+ webinars in the 2026 report, the average attendance rate was 49% — and most of those webinars were B2B.

Read the fine print before you rebuild your Q4

This is platform data, not a census. The 2026 report analyses over 2,000 webinars hosted on Univid between January 2023 and August 31, 2026, across SaaS, B2B software, professional services, education and events.

Two caveats that change how you should use it. The dataset is 70% European, 20% US and 10% other regions. And it's made up of external-facing webinars, the majority being B2B sales and marketing sessions.

European B2B has a summer shutdown that American consumer course audiences simply do not. August in Sweden is not August in Scottsdale. A creator selling a $297 course to freelancers may find July audiences perfectly awake — and competing against almost nobody.

Which is the actual opportunity hiding in the seasonality chart. Everyone reads "43% in fall" as confirmation they picked the right season. The more useful reading is that two-thirds of the calendar has been quietly abandoned by the people you're competing with.

If your fall webinar underperforms this year, the content may have been fine. There were just forty-two other invitations sitting above yours.
