How far in advance should I start promoting an event on LinkedIn?

Two to three weeks of substance-first posts works for most webinars and launches. Start by posting the ideas the event will cover, not the date. The registration push in the final week converts because the earlier posts already proved the content is worth the time.

Should I put the registration link in the post or the comments?

Comments, in most cases. LinkedIn tends to suppress reach on posts with external links in the body, so leading with the substance and dropping the link in the first comment usually reaches more of the right people.

How do I promote an event without annoying my audience?

Make the promotional posts useful on their own. If each post teaches something even to people who never register, the audience doesn't experience it as spam. The reminder-only countdown is what wears people out, because those posts give nothing back.

Goal

Fill a webinar, launch, conference talk, or community event with the right people, using content that builds interest instead of just broadcasting a date.

Founders, marketers, and community leads running webinars, product launches, meetups, or speaking slots who need registrations from a B2B audience.

What to write about

+Post the substance early. Share one genuinely useful idea from the event's topic a week or two out, then mention the event covers more of it.
+Introduce the people. A post about who's speaking and why their perspective is worth an hour does more than the speaker's headshot on a banner.
+Frame the specific problem the event solves, and who should care. Vague "join us to learn about growth" loses to "if you're stuck at the same MRR for two quarters, this is for you."
+Share a preview that stands alone. A single slide, stat, or framework from the talk gives people a reason to want the rest.
+Keep promoting after it ends. A recap post with the key takeaways reaches everyone who missed it and seeds the next one.

Example post

Running a session next Thursday on pricing for early-stage SaaS. Here's one thing we'll get into: almost every founder I talk to discounts too early, usually out of fear, and it quietly trains the whole market to expect the discount. We'll cover how to hold the line without losing the deal. Link's in the comments if that's a problem you're sitting with right now.

How to know it's working

→Registrations attributable to your organic posts, not just paid or email.
→Show-up rate, since people who registered off useful content tend to actually attend.
→Quality of attendees, measured by whether the right roles and companies registered.
→Engagement on the pre-event posts, which previews whether the topic is landing.
→Post-event inbound, like replies and DMs referencing what you covered.
