In a community, your words are your “User Experience.” A well-written challenge can feel like a game; a poorly written one feels like homework. This guide helps you strike the right tone and structure your content for maximum engagement.
Time to Read: 6 minutes Goal: Increase challenge completion rates by improving your copy and imagery.

​
1. The Power of the Hook (Titles)

Your title is the only thing a user sees before they decide to click.

​
2. The “Hand-Holding” Description

Once they click, don’t overwhelm them. Use the 3-S Rule:
  • Short: Keep descriptions under 200 characters if possible.
  • Specific: Tell them exactly what to do. “Watch the video and answer the 3 questions below.”
  • Social: Use “We” and “You.” “We’d love to hear your thoughts on this!“

​
3. Imagery: More Than Just Decoration

A custom image gives a challenge a far better chance of being clicked than the default treatment.
  • Use faces: Humans are biologically wired to look at faces. Use photos of your team or community members.
  • Avoid generic stock: A real photo of your office is better than a high-res photo of a generic office.
  • Brand colors: Use your primary brand color in the background of your images for consistency.
  • Meme responsibly: A well-placed meme can drive huge engagement, but use them sparingly so they don’t lose their “spark.”

​
Image sizes

Each entity crops to its own aspect ratio, so there is no single correct size:
Challenge images are locked to square. The challenge cropper does not let you change the aspect ratio, so a 4:3 upload gets cropped to 1:1 whether you want it to or not. Compose challenge art square from the start, and keep anything important away from the edges.

​
4. Structuring Action Steps

If a challenge has multiple steps, order them by increasing difficulty:
  1. Step 1 (Easy): “Click here to see the new feature.” (Get them committed).
  2. Step 2 (Medium): “What is your favorite part about it?” (Get them thinking).
  3. Step 3 (Harder): “Record a 30-second video of you using it.” (The big win).
Getting someone through an easy first step is the best thing you can do for your completion rate. Once they’ve started, they’re far more likely to see it through. Reorder steps by dragging the handle on each action in the challenge’s Actions list. The order you set is the order members see.
Save the challenge before reordering. On a challenge you haven’t saved yet, the list will appear to reorder but the new order isn’t persisted.

​
5. The completion screen

When a member finishes the last action, Nudj shows a completion screen with their reward. Your community uses one of two versions:
  • Immersive (the default): a multi-step sequence covering stats, points, XP, leaderboard position, rewards, and any badge earned.
  • Classic (opt-in): a single screen instead of the multi-step sequence.
None of the completion copy is per-challenge. There is no success-message field on a challenge, so you can’t write a bespoke celebration for one of them. Everything below is community-wide.
What you can actually change:
  • Colors, via Experience -> Settings -> Common Branding, then open Challenge Complete Screen. This is a community-level setting, so every challenge in the community shares it. Two challenges can’t have different completion colors. Until you set a value here the community inherits the organisation default from Org Settings -> Brand Defaults -> Branding. These colors only reach the immersive version; the classic screen ignores them.
  • Wording, via Org Settings -> Advanced -> Languages, then Edit on a language and change the challenges.complete.* keys. These drive both versions. challenges.complete.title (“Challenge Complete!”) and subtitle (“Congratulations on your achievement!”) are the immersive screen’s opening heading, and badge_unlocked (“Badge Unlocked!”) heads its badge step.
Because the celebration is fixed, put your personality in the parts you do own: the title, the description, and the reward name members see when they land there.

The Engagement Checklist

Before you hit “Live,” ask yourself:
  • Does the title make me want to click?
  • Is the first step so easy they can’t say no?
  • Is it clear what they get at the end?
  • Does the image look good on mobile?
