Last updated: March 2026 · Reading time: 16 min
A webinar platform is software that enables live or pre-recorded video presentations to an online audience, typically including registration pages, attendee engagement features, and analytics.The global webinar market reached $4.2 billion in 2025 and is growing at 14.3% annually (MarketsandMarkets, 2025). B2B marketers rank webinars as their #2 content format for lead generation behind only blog posts, with 73% of B2B marketers saying webinars produce the highest quality leads (DemandGen Report, 2024).
“We’ve tested dozens of webinar tools. The difference between a good platform and a great one isn’t the feature list. It’s the attendee experience. If your audience has to download software, troubleshoot audio, or refresh their browser three times, your content doesn’t matter. The best platform is the one your audience doesn’t notice.” Hardik Shah, Founder of ScaleGrowth.Digital

The average webinar attracts 148 registrants and sees a 44% attendance rate (ON24, 2024). For your first webinar, expect 50-100 registrants if you promote to an existing email list of 1,000+ contacts. Cold audiences (paid ads, social promotion) typically register at 2-5% of impressions. Focus on delivering value to whoever shows up rather than chasing a target number.
45-60 minutes performs best for most B2B webinars. That breaks down to 35-40 minutes of content and 15-20 minutes for Q&A. Webinars under 30 minutes feel too short for the registration commitment. Over 90 minutes, drop-off rates spike above 50%. The sweet spot is 45 minutes: long enough to deliver real value, short enough to fit in a lunch break.
Free plans work for small, internal events. For lead generation webinars, pay for a platform. The differences that matter are custom registration pages (brand trust), email automation (attendance rates), analytics (ROI tracking), and CRM integration (lead routing). A $50-80/month platform that generates 10 qualified leads per webinar pays for itself immediately.
Riverside is the best option for dual use. It records each participant locally at studio quality, making recordings suitable for both webinar replays and podcast episodes. StreamYard also works for both, though recording quality is lower. For most teams, separate tools for webinars and podcasts will give better results since the workflows and audience expectations differ.
Tuesday, Wednesday, and Thursday between 10-11am in your primary audience’s time zone consistently produce the highest attendance rates. ON24 data from 2024 shows Wednesdays at 11am produce 26% higher attendance than Friday webinars. Avoid Mondays (inbox overload) and Fridays (early weekend mode). If your audience spans time zones, 1pm ET works as a reasonable compromise for US audiences.
