Most event organizers overspend on paid ads. See how LinkedIn peer sharing through Attendir delivers higher-quality registrations at a fraction of the cost.
The paid ads problem
Event organizers routinely spend thousands on LinkedIn and Facebook ads to fill seats. But the economics are brutal: LinkedIn Ads cost €5-12 per click, and only 2-5% of those clicks convert to registrations. That means you are paying €100-600 per registration from paid channels.
For a 500-person event, a paid ads budget of €10,000-50,000 is common — and much of that spend reaches people with no connection to your brand or industry. There is a better way.

Why peer sharing beats paid ads
LinkedIn impressions
For a 500-person event at 20% share rate, that is 100 sharers × 500 connections = 50,000 organic impressions from trusted sources — not cold ad placements.
Lower cost per registrant
At €990/mo for Unlimited, if 100 attendees share to 500 connections each, that is 50,000 impressions. At a conservative 0.1% conversion, that is 50 registrations at €19.80 each — vs €100-600 from paid ads.
