How to Write a LinkedIn Post About an Event

Writing a LinkedIn post to promote your event can feel like a high-stakes task, as you need to move beyond simply announcing it and actually persuade people to give you their time. A great event post transforms a simple announcement into an engaging invitation that drives registrations and builds a community. This guide walks you through a complete strategy - before, during, and after your event - to turn your LinkedIn into a powerful tool for event marketing.

Before the Event: Building Excitement and Driving Registrations

The work starts long before your event goes live. Your goal is to build a steady hum of anticipation that grows into a roar of sign-ups. This isn't about spamming your network, it's about a strategic sequence of posts that inform, excite, and persuade. Treat this period as a mini-campaign with distinct phases.

1. The Big Announcement Post

This is your starting line. The goal of this first post is to clearly communicate what the event is, who it's for, and why they absolutely cannot miss it. Keep it scannable and value-focused.

What to include in your announcement post:

• A Killer Hook: Start with a question or a bold statement that speaks directly to your target audience's pain points or aspirations.
• The "What" and "Why": Clearly state the event name and the main benefit. What problem will you solve? What will attendees learn?
• The "Who": Mention any key speakers or special guests. Why are they the right people to listen to on this topic?
• Key Details: Include the date, time, and whether it's virtual or in-person.
• Visuals: A well-designed event banner or a short, energetic video is non-negotiable.

Include a clear link to the registration page. Use phrases like "Save your spot" or "Register for free."

2. The Speaker Spotlight Series

Your speakers are one of your biggest assets. They add credibility and bring their own audiences. Dedicate individual posts to each key speaker in the weeks leading up to the event.

How to structure a speaker spotlight post:

• High-Quality Headshot: Use a professional photo of the speaker.
• Introduce Them: Mention their name, title, and a few impressive accomplishments. What makes them an expert on their topic?
• Tease Their Session: Give a sneak peek into what they'll be talking about. Frame it around the problem they'll solve for the audience.
• Why they are excited: If possible, get a quote from the speaker about why they are looking forward to the event. This adds a personal touch.
• Tag Them and Their Company: This is a must. It notifies them of the post (prompting a reshare) and exposes your event to their network and company followers.

3. Share Behind-the-Scenes Content

People love seeing the process. Behind-the-scenes (BTS) posts make your event feel more real and your brand more human. It shows the effort you're investing and builds a connection with your audience.

Behind-the-scenes post ideas:

• A short video of your team during a planning session.
• A photo of the venue being set up (for in-person events).
• A screenshot from a tech run-through with one of the speakers (for virtual events).
• A post asking your audience what questions they want a specific speaker to answer.

Keep these posts casual and authentic. The goal is to make your followers feel like insiders.

4. The Countdown and 'Last Chance' Posts

As the event date approaches, use urgency to your advantage. Countdown posts create a sense of anticipation, while "last chance" posts push fence-sitters to finally register.

• One Week Out: Post a rundown of the agenda or the top 3 reasons to attend.
• Three Days Out: Share a testimonial from a past event attendee or a quick video from a speaker saying they can't wait to see everyone.
• 24 Hours Left: This is your "Last Chance to Register" post. Keep the copy short and the CTA very clear.

During the Event: Turn Attendees into Advocates

Your job isn't over once the event starts. Posting during the event keeps the conversation going, engages remote followers, and generates valuable social proof. Create a simple content plan ahead of time so you can post quickly without missing a moment.

1. "We're Live!" Kick-Off Post

Start with a high-energy post the moment the event begins. Use a photo from the stage or a screenshot of the opening speaker on the webinar. This signals that the event has started and gives last-minute attendees one final nudge to join.

2. Share Real-Time Bites and Key Quotes

Capture powerful quotes, surprising statistics, and "aha" moments from your speakers. You can share these as simple text posts, but they work even better as quote graphics you’ve prepared in a template beforehand.

This provides immediate value to your entire network, not just your attendees, and showcases the quality of your event content.

Example text:

"Stop chasing algorithms and start building community. That's the only competitive advantage you can sustain." - Powerful opening from Julia Pham at #ModernMarketersPlaybook

So much insight being shared already. If you're here, what's been your favorite takeaway so far? 👇

3. Encourage and Reshare User-Generated Content (UGC)

Your attendees are your best marketers. Before the event, make sure you promote a unique event hashtag (e.g., #ModernMarketersPlaybook). During the event, encourage attendees to share their biggest takeaways, photos of their setup, or their thoughts using the hashtag.

Keep an eye on the hashtag feed and reshare the best posts. This creates a sense of community and provides authentic testimonials in real-time.

After the Event: Keep the Momentum Going

The conversation doesn't end when the curtains close. The post-event phase is your opportunity to reinforce key messages, deliver more value, and build your audience for the future. Don't let the buzz die down.

1. The Big "Thank You" and Recap Post

Within 24 hours of the event's end, post a heartfelt thank you. Acknowledge your speakers, sponsors, your team, and everyone who attended.

What to include in your recap post:

• Express Gratitude: A genuine thank you goes a long way.
• Share Key Numbers: Highlight impressive stats like the number of attendees, countries represented, or questions asked. This provides social proof of the event's success.
• Post the Best Photos/Screenshots: Create a carousel post with candid photos of attendees networking, speakers on stage, or screenshots of lively chat from a virtual event.
• Ask for a Favorite Moment: End with a question like, "What was your main takeaway?" to restart the conversation in the comments.

2. Share Session Recordings and Resources

This is arguably your most valuable post-event asset. A few days after the event, share a post announcing that the session recordings, presentation slides, or other resources are now available. This serves two purposes:

1. It provides tremendous value to those who attended and want to revisit the content.
2. It acts as a powerful lead magnet for those who couldn't make it. You can gate the recordings behind a simple email capture form to grow your newsletter list.

3. Keep the Conversation Going with Takeaways

Don’t post the recap just once. You can repurpose content for weeks. Create individual posts that highlight one key idea or takeaway from each speaker or session. You can create a graphic, a short video clip (an audiogram or a video snippet from the session), or even a short article. This continues to provide value, showcases the depth of your event, and gives you more opportunities to tag your speakers again, extending the reach of your event well beyond the day it happened.

This extended "content echo" ensures your single event fuels your LinkedIn strategy for weeks or even months.

Final Thoughts

A successful event promotion plan on LinkedIn is a thoughtfully sequenced campaign that provides value at every stage. By moving beyond a single announcement post and adopting a before, during, and after strategy, you can build genuine anticipation, engage your audience deeply, and extend the life of your event long after it’s over.

Planning this multi-post sequence ahead of time is critical to avoiding last-minute stress. After mapping out our entire promotion timeline, we love loading all the "before" and "after" posts into the visual content calendar inside Postbase. This allows us to see the whole campaign at a glance and schedule everything in one go, freeing up our team to focus on community engagement as the big day approaches.
