Methodology

This report combines data from three sources: (1) Attendir platform analytics from active campaigns, (2) published industry research including Snoball's Event Advocacy Benchmark Report, and (3) LinkedIn engagement data from 360Brew and industry publications.

We update this report quarterly. All data points are sourced and cited. Where sample sizes are small, we note ranges rather than precise figures. Benchmarks are based on B2B events with 100–5,000 attendees unless otherwise noted.

Our goal is transparency. If you have campaign data to contribute, we welcome anonymized submissions to strengthen these benchmarks across event types and industries.

Sharing Rate Benchmarks by Event Type

Event Type	Avg Share Rate	Top Quartile	Bottom Quartile	Key Factor
B2B Conferences (500+ attendees)	22–28%	35%+	10–15%	Professional motivation
Tech Summits & Startup Events	25–35%	40%+	15–20%	Tech-savvy, active LinkedIn
Trade Shows & Expos	15–22%	28%+	8–12%	Exhibitor/sponsor sharing
Professional Networking Events	20–28%	32%+	12–18%	Social signaling
Virtual & Hybrid Events	25–35%	42%+	15–22%	Immediate digital access
Corporate Internal Events	12–18%	25%+	5–10%	Less public motivation

Share rates above 30% typically indicate strong incentivization (raffle or prize), optimal timing (share prompt within 5 minutes of registration), and branded card design quality. For tips on maximizing your share rate, see our case studies from TEDAI Vienna and ViennaUP.

Channel Distribution

Channel	Share of Traffic	Avg CTR	Best For
LinkedIn	58–65%	3.2–4.8%	B2B conferences, professional events
Dark Social (WhatsApp, Slack, private)	20–25%	Higher (trusted context)	Peer-to-peer referrals
X (Twitter)	5–8%	1.5–2.5%	Tech events, startup community
Email (forwarded links)	5–8%	2.0–3.5%	Corporate events, internal sharing
Facebook	2–4%	1.0–2.0%	Consumer events, community events

LinkedIn dominates B2B event advocacy traffic, but dark social (WhatsApp, Slack, private messages) accounts for over a fifth of all shares and often converts at higher rates due to the trusted, one-to-one context. Tracking dark social requires UTM parameters on shared links.

Click-Through & Conversion Rates

Metric	Attendee Advocacy	LinkedIn Ads	Google Ads	Email Marketing
Avg CTR	3.2–4.8%	0.4–0.8%	2–5%	1–3%
Landing → Registration	31.9%	5–10%	2–5%	1–3%
Cost Per Registration	€2–5	€25–50	€15–40	€1–3
Trust Signal	Very High (peer rec)	Low (ad)	Medium (search intent)	Medium (opt-in)
Scalability	Viral (network effects)	Budget-limited	Budget-limited	List-limited

The 31.9% landing-to-registration conversion rate for advocacy traffic is remarkably high compared to other channels. This is because advocacy-driven visitors arrive with a built-in trust signal: a peer they know is already attending. Use our ROI calculator to model these numbers for your specific event.

LinkedIn Engagement Benchmarks for Event Content

Post Type	Avg Engagement Rate	Reach Multiplier	Notes
Carousel/Document posts	24.42%	3–5× vs text	Highest reach in 2026 algorithm
Image posts (sharing cards)	8–12%	2–3× vs text	Attendir default format
Video posts	6–10%	1.5–2× vs text	Resource-intensive
Text-only posts	4–6%	1× (baseline)	Declining reach
Link posts	2–4%	0.5–0.8× vs text	Algorithm penalizes external links

LinkedIn algorithm update (2025): The 360Brew algorithm update decreased overall organic reach by approximately 50% and penalizes AI-generated content by 47%. Saves and Sends now outweigh Likes for distribution. Carousel posts achieve the highest reach at 3–5× text posts. This is why authentic peer sharing through advocacy tools now outperforms brand-generated content for event promotion.

Cost Comparison: Advocacy vs Paid Marketing

Channel	Monthly Cost	Avg Registrations	Cost Per Reg	ROI (€200 ticket)
Attendir (Unlimited)	€990/mo	85–200	€2–5	17–40×
Attendir (Lite)	€390/mo	30–50	€8–13	5–10×
LinkedIn Ads	€2,500/mo	50–100	€25–50	2–4×
Google Ads	€2,000/mo	50–130	€15–40	2.5–6.5×
Email Marketing	€200/mo	20–60	€3–10	4–20×
Manual sharing	Free	5–15	€0 (but 8–15 hrs/event)	Infinite (time cost)

ROI calculations assume a €200 average ticket value, which is typical for mid-market B2B conferences. For events with higher ticket prices, the ROI multiplier increases proportionally. See our pricing page for current plan details, or use the ROI calculator to model your specific scenario.

Year-over-Year Trends

2024

Attendee advocacy emerged as a category. Early adopters reported 15–20% share rates. Tools were primarily enterprise-focused with lengthy onboarding cycles and high price points.

2025

LinkedIn algorithm changes reduced organic reach by 50%. Advocacy became essential to cut through noise. Share-to-registration conversion data was published (31.9%). Self-serve tools like Attendir made advocacy accessible to smaller events.

2026

AI-generated content penalized by LinkedIn (47% lower reach). Authentic peer sharing via advocacy tools now outperforms brand content. Carousel and document posts achieve 3–5× higher reach. Gamification drives 48% engagement increase.

Industry Takeaways

1

Attendee advocacy costs 5–10× less per registration than paid ads. At €2–5 per advocacy-driven registration versus €25–50 for LinkedIn Ads, the economics are compelling for events of any size. Compare tools →
2

LinkedIn remains the dominant channel for B2B event sharing (58–65%). Despite algorithm changes reducing organic reach, peer-shared event content consistently outperforms brand posts because it carries authentic social proof.
3

Timing is everything. Share prompts delivered within 5 minutes of registration maximize conversion. Delayed prompts see significantly lower share rates as the moment of excitement passes.
4

Gamification (raffles, leaderboards) increases sharing rates by up to 48%. Adding a raffle or competitive element turns passive attendees into active promoters. Even simple prize draws meaningfully lift participation.
5

Virtual events see 25–35% higher share rates than in-person events. Immediate digital access removes friction. Virtual attendees are already at their devices and can share in one click without context-switching. Learn how to measure ROI →

Frequently Asked Questions

What is a good share rate for an event advocacy campaign?

A good share rate is 20–30% of registered attendees. Top-performing campaigns with strong incentivization (raffles or prizes), optimal timing (share prompts within 5 minutes of registration), and high-quality branded sharing cards can exceed 35%. Tech summits and virtual events tend to see the highest rates at 25–35%, while corporate internal events typically fall in the 12–18% range.

How does attendee advocacy compare to paid advertising?

Attendee advocacy costs roughly 5–10× less per registration than paid advertising. Advocacy-driven registrations cost approximately €2–5 each, compared to €25–50 for LinkedIn Ads and €15–40 for Google Ads. Advocacy also benefits from higher trust signals since recommendations come from peers, and it scales virally through network effects rather than being limited by ad budgets. See the full cost comparison in our ROI calculator.

Which event types get the highest share rates?

Virtual and hybrid events see the highest share rates at 25–35%, followed closely by tech summits and startup events. B2B conferences with 500+ attendees average 22–28%. The key factors are audience tech-savviness, professional motivation to share, and how easy it is to access sharing tools immediately after registration. See detailed breakdowns by event type in the use cases section.

How often is this benchmark report updated?

This benchmark report is updated quarterly with the latest data from Attendir platform analytics, published industry research, and LinkedIn engagement studies. Each update includes new data points, trend analysis, and revised benchmarks to reflect changes in social platform algorithms and attendee behavior patterns.

Can I contribute data to this benchmark?

Yes, we welcome contributions from event organizers who want to share anonymized campaign data. Contributing data helps make these benchmarks more accurate and representative across different event types and industries. Contact us to discuss sharing your campaign data.

Where does the 31.9% conversion rate come from?

The 31.9% share-to-registration conversion rate comes from Snoball's Event Advocacy Benchmark Report, which analyzed conversion data across attendee advocacy campaigns. This figure represents the percentage of people who, after clicking a peer-shared event link, completed registration. It is one of the most cited data points in the attendee advocacy space and reflects the high-trust, high-intent nature of peer referral traffic.
