Key takeaways

Webinar promotion social media cost in the UK is typically £300–£1,000 per event for 4 to 10 hours of posts, graphics, ads set-up and reminders, plus a media budget. Promote for two to three weeks. Reminders matter as much as sign-ups, because many registrants do not attend.

• £300–£1,000 per event is the indicative fee for webinar promotion.
• Promote for two to three weeks before the date.
• Reminders on the day lift attendance as much as new sign-ups.
• Clips from the recording extend the value afterwards.

How much does webinar promotion cost?

Promoting one webinar takes about 4 to 10 hours of posts, graphics, event set-up, ads and reminders, which is £300–£1,000 at the £75–£100 an hour implied by typical UK retainers. The media budget is separate. These are indicative figures, not a GBL price list.

• Announcement and speaker posts.
• Event listing and registration ads.
• Reminder sequence before and on the day.
• Media budget: separate, often LinkedIn for B2B.

• LinkedIn ads management costs in the UK

How do you turn sign-ups into attendees?

Send reminders a day before, an hour before and at the start, by email and on social. Keep the title specific about what people will learn. Offering the recording to registrants who cannot attend keeps them engaged and gives you a reason to follow up.

What happens after the webinar?

The recording becomes content. Short clips of the best answers, a summary post and a few quote graphics can run for weeks. Follow up attendees quickly with a clear next step. Most of the value of a webinar comes after it ends.

• Podcast clips for social media: what editing costs

When is paid webinar promotion not worth it?

Paid promotion is not worth it when the topic is too broad, when you have no follow-up offer, or when a few emails to existing contacts would fill the session. Start with your own audience, and add ads only when you need more of the right people.

What does this look like in practice?

A pattern we see with UK B2B and training clients: plenty of sign-ups but low attendance and no follow-up. Global Bridge Labs (GBL) plans the reminder sequence and the post-webinar clips as part of the promotion, so each session keeps producing content and conversations afterwards.
