Challenges come in four distinct flavors, each designed for different engagement outcomes. Pick the right format and your community will naturally engage the way you intended. Pick wrong, and you’ll be fighting against the mechanics.

The Four Challenge Formats

Knowledge Challenges

Quiz-based challenges that teach, verify understanding, and certify competency. Perfect for onboarding, training, and education.

Community Challenges

Activities that drive interaction within your platform. Great for building relationships and engagement.

Creative Challenges

User-generated content campaigns where members create and share. Ideal for showcasing community talent.

Social Challenges

External sharing and amplification on social platforms. Perfect for viral campaigns and brand advocacy.

Knowledge Challenges

Teach something, test understanding, certify learning. People prove they know their stuff. Example: Product Training Challenge
  1. Watch embedded training video (Rich Media)
  2. Answer quiz questions (Multiple Choice, Specific Answers)
  3. Earn badge/certificate on completion
Example: Certification Program
  1. Read learning materials (External Links)
  2. Complete assessment (Multiple Choice with correct answers required)
  3. Pass with 80%+ to unlock certificate
Example: Onboarding Knowledge Check
  1. Quick video intro (Rich Media)
  2. True/False warm-up (2-option Multiple Choice)
  3. Specific answer questions about key concepts
  4. Final multiple choice assessment
Completion rates vary: mandatory certifications hit 65-85%, voluntary learning hits 40-50%. The difference? One you have to do, the other you want to do.
Knowledge challenges work best when the content is actually valuable to users, not just compliance theater. People can smell the difference.

Community Challenges

Pull members into interaction with each other. Someone posts, another comments, a third reacts—suddenly there’s momentum and belonging. These challenges weave people together. Example: Onboarding & Connection
  1. Introduce yourself in a post (Platform: Create Post)
  2. Comment thoughtfully on 2 other introductions (Platform: Comment)
  3. Like 5 posts from the week (Platform: Like)
  4. Optional: Recommend a new member to connect with (manual or automated)
Example: Peer Learning & Help
  1. Share something you learned recently (Platform: Create Post)
  2. Help answer someone’s question (Platform: Comment)
  3. React with encouragement to 3 others (Platform: Like)
Example: Feedback & Listening
  1. Answer a community poll (Platform: Vote)
  2. Comment with your perspective (Platform: Comment)
  3. Read responses from others and react (Platform: Like)
Easy social challenges hit 50-70% completion. Ones requiring more effort drop to 30-45%. Frame participation as helping, not as tasks. People move mountains for community but resist busywork.
Community challenges work best when they feel natural, not forced. “Help someone solve a problem” beats “participate in discussion.”

Creative Challenges

Ask members to make something and share it. A photo, video, design, testimonial—something that required their hands, brain, or voice. These create ownership and pride. Example: User Testimonial Campaign
  1. Record a short video: “Why I love [product]” (Rich Media: Video Upload)
  2. Optionally share on LinkedIn (Social: LinkedIn Share)
  3. Optional: Vote on favorite testimonials (Platform: Vote on submitted content)
Example: Photo Contest
  1. Take a photo related to your community (Rich Media: Image Upload)
  2. Rate & comment on 3 other entries (Platform: Comment & Rate)
  3. Top 5 get featured + bonus XP
Example: Creative Showcase & Feedback
  1. Submit your creative work - design, art, writing, etc. (Rich Media: File Upload)
  2. Leave constructive feedback on 2 submissions (Platform: Comment)
  3. React with appreciation to 5 pieces (Platform: Like)
Simple uploads hit 40-60% completion. Requiring real creativity drops to 25-40%. Specific, inspiring prompts beat generic ones. “Share a photo of how you use our product in your daily life” gets way more engagement than “share anything related to our brand.”
The prompt is everything. Specific, inspiring prompts get better responses than generic “share anything” requests.

Social Challenges

Ask members to share on their personal social accounts—Twitter, LinkedIn, TikTok, wherever they already live. You’re borrowing their reach and their credibility with their networks. Example: Product Launch Amplification
  1. Share the launch announcement on LinkedIn (Social: LinkedIn Share)
  2. Optional: Tweet about it (Social: Twitter Share)
  3. Optional: Share on Instagram Stories (Social: Instagram Share)
Example: Brand Advocacy
  1. Share a customer success story (Social: LinkedIn Share)
  2. Personalization: Add your own experience (optional text)
  3. Complete when shared and visible
Example: Event Promotion
  1. Share the event link on Twitter (Social: Twitter Share)
  2. Tag 2 colleagues who should attend (Social: Twitter Share with mentions)
  3. Optional: Share on LinkedIn for broader reach (Social: LinkedIn Share)
Example: Thought Leadership
  1. Share an article from your blog (Social: LinkedIn Share)
  2. Add personal commentary (optional text field)
  3. Complete when posted
Completion rates are naturally lower (20-40% for easy valuable shares, 5-15% if it requires effort or feels risky) because members must leave your platform. But that’s exactly why it works—they’re sharing with their people who trust them, not marketing messages. Make the share valuable for them, not just for you. “Share this article about industry trends” gets traction because it helps their professional reputation. “Promote our company” doesn’t.
Your members’ credibility is on the line. Make sure whatever they’re sharing is actually valuable to their audience, not just yours.

How to Choose Your Format

The decision is usually obvious once you know what you actually want to happen. Teaching? Knowledge. Relationship building? Community. Getting member content? Creative. Reaching beyond your platform? Social. That’s it. If you’re torn between two, they probably layer well together anyway.

Pro Strategies for Combining Formats

Layer formats for depth. Knowledge + Community is powerful: “Learn this skill, then help someone else learn it.” Learning gets verified and reinforced through teaching. Engagement doubles because each format feeds the other. Stack them over time. Social → Knowledge → Community → Creative is a natural progression. Start easy (share our launch on LinkedIn), build involvement (learn how to use the product), deepen relationships (help onboard new members), then celebrate (show what you built with it). People move through progressively, each step earning the next. Different audiences, different formats. New members respond to Community (belonging) + Knowledge (context). Active members are ready for Creative (express themselves) + Social (advocate). Power users can handle all formats with increasing complexity.
