How to double your webinar audience with partner hosting

Executive overview

Most webinars struggle to grow because they rely on the host's existing audience alone. Co-hosting with a complementary brand can double or triple reach without extra ad spend.

The fastest way to grow a webinar audience is to share it with a partner who has a different but overlapping customer base.

The four-step partner webinar framework

1. Find a partner with a similar but not identical audience — overlap in interest, not in product (e.g. SEO agency + e-commerce platform)
2. Create a promotional schedule — align on timing, design aesthetic, and brand voice before promoting
3. Run a practice session — confirm platform access and technical setup before the live event
4. Define a post-webinar strategy — plan how you'll convert attendees and follow up with no-shows

Promoting to a larger audience

• Use tools like Restream to simulcast the webinar live across all social channels simultaneously
• Don't just post a text announcement — go live so followers engage in real time
• Email is the top channel for webinar registrations; conversion rates run ~27% higher than average

Post-webinar follow-up

• Email non-attendees the recording — many registrants don't attend on the day
• Email registrants who signed up but didn't show — they expressed intent and are worth re-engaging
• Pitch products and services inside the webinar only after delivering genuine value
