## Questions owners ask

**What is a webinar funnel?** The path from an ad or post to a free live session to a paid offer at the end: people register, some attend, and some attendees buy.

**What share of registrations usually attend?** ON24, a webinar platform, reported that 60% of registrations became attendees across webinars on its platform in 2025, up from 57% in 2024. That counts people who watched the recording later, and it is mostly business-to-business events, so expect a lower live show-up for a free consumer workshop. Your own last session is the best number to use.

**Which number should I work on first?** The one furthest below what you expect. Each one multiplies the others, so a better show-up rate is worth as much as a better buying rate. Show-up usually depends on reminders and on how soon after registering the session runs.

**What does value per registration tell me?** Revenue divided by registrations: the most a registration can cost in ads before the session stops paying for itself, before your own time and other costs.
