Reddit Carousel Ads: How to Create Them
Reddit carousel ads display multiple images or cards that users swipe through, telling a story or showcasing products in sequence. When done well, carousel ads drive higher engagement than single-image formats by inviting users to explore.
This guide covers everything you need to create effective reddit carousel ads—from specifications to strategy.
What Are Reddit Carousel Ads?
Carousel ads feature 2-6 cards that users swipe horizontally. Each card can include:
- Image
- Headline
- Description (optional)
- Unique destination URL (optional)
Users engage by swiping through cards, creating multiple touchpoints within a single ad unit.

Carousel Ad Best Practices
Tell a Story
Design cards as a sequence, not isolated images:
Story arc approaches:
- Problem → Solution → Result → CTA
- Feature 1 → Feature 2 → Feature 3 → Value prop
- Before → During → After → CTA
- Question → Answer → Proof → CTA
Users who swipe are engaged—reward them with narrative progression.
Make the First Card Count
The first card determines whether users swipe:
- Lead with your strongest visual
- Create curiosity that invites exploration
- Include clear visual indicator that more content exists
- Avoid putting all key information on card one
Maintain Visual Consistency
Cards should feel connected:
- Use consistent color palette across cards
- Maintain similar visual style and quality
- Consider cards as parts of a larger canvas
- Use design elements that span multiple cards
Optimize for Mobile
Most Reddit users browse on mobile:
- Test how text appears on small screens
- Keep headlines short (25-40 characters)
- Ensure images are legible at mobile size
- Use high-contrast text on images
Use Card-Specific URLs Strategically
Each card can link somewhere different:
Product catalogs: Link each card to its product page
Feature tours: Link to feature-specific landing pages
Sequential content: Link to related blog posts or resources
Track card-level performance to optimize URL strategy.

Optimization Signals
Use card-level data to optimize:
- High card 1 clicks, low swipes: Card 1 is strong, but not inviting exploration
- Drop-off after card 2: Cards 3+ may be weak—reorder or replace
- Most clicks on final card: Story structure is working
- Even distribution: All cards contributing value
Testing Approach
A/B test carousel elements:
- First card imagery
- Card order and sequence
- Number of cards (3 vs. 5 vs. 6)
- Headlines and descriptions
- URL strategies (single vs. per-card)
Common Mistakes to Avoid
Too Much Text on Images
Images with heavy text overlays perform poorly. Keep text minimal; use headline fields for messaging.
Weak First Card
If card one doesn't compel swiping, users won't see the rest. Invest extra effort in the opener.
No Narrative Logic
Random images without connection confuse users. Design intentional sequences.
Inconsistent Quality
One poor-quality image damages the entire carousel. Maintain consistent quality across all cards.
Ignoring Mobile Experience
Carousels that look great on desktop may fail on mobile. Always preview and test on mobile devices.

FAQs
How many cards should I use in a Reddit carousel ad?
Use 3-5 cards for most campaigns. Two cards feel incomplete; six cards risk drop-off. Test different lengths—some audiences prefer shorter carousels, others engage with longer stories. Match card count to content needs rather than using maximum allowed.
Can each carousel card link to a different URL?
Yes. You can set a default destination URL for all cards or specify unique URLs per card. Per-card URLs work well for product catalogs where each card features a different item. Track click distribution to see which cards drive traffic.
Do carousel ads cost more than single-image ads?
Carousel ads use the same bidding and pricing as other formats. Cost depends on targeting, competition, and bid strategy—not format. However, carousels may deliver more engagement per impression, potentially improving effective cost metrics.
