Reddit Conversation Ads: Complete Guide & Best Practices

Reddit Conversation Ads place your advertising directly within active discussion threads—the heart of what makes Reddit unique. Unlike feed ads that appear while scrolling, conversation ads integrate into the comment sections where genuine discussions happen.

This format offers exceptional engagement potential, but it demands a fundamentally different creative approach. Here's everything you need to know about Reddit Conversation Ads in 2026.

What Are Reddit Conversation Ads?

Conversation Ads are a Reddit advertising format that places your promoted content within comment threads rather than the main feed. When users click into a post to read and participate in the discussion, your ad appears alongside organic comments.

Key Characteristics

Feature	Conversation Ads	Feed Ads
Placement	Within comment sections	Main scrolling feed
User Context	Active discussion mode	Passive browsing mode
Engagement Type	Part of conversation	Standalone content
Headline Limit	100 characters	150 characters
User Interaction	Comments enabled by default	Comments optional
Ideal Tone	Conversational, helpful	Promotional acceptable

Why Conversation Placement Matters

Users reading comments are in a different mental state than those scrolling the feed:

• Higher intent: They clicked into a post, showing active interest in the topic
• Discussion mindset: They're prepared to engage with content and comments
• Trust context: They're reading peer opinions and recommendations
• Longer dwell time: Comment sections encourage deeper engagement

When your ad appears in this context, it benefits from the trust and attention users bring to discussions.

How Conversation Ads Work

Understanding the mechanics helps you create more effective campaigns:

Placement Logic

Reddit's algorithm places conversation ads based on:

• Subreddit targeting: Ads appear in threads within your targeted communities
• Interest relevance: Content matching between ad and discussion topics
• User behavior: Engagement patterns and community participation
• Auction dynamics: Bid competition for premium placements

Visibility Positioning

Conversation ads typically appear:

• Within the top portion of comment sections
• Labeled as "Promoted" to maintain transparency
• Styled similarly to organic comments (but clearly marked as ads)

User Interactions

Unlike some ad formats, conversation ads fully enable:

• Upvotes and downvotes: Users can vote on your ad
• Comments: Users can reply directly to your ad
• Saves and shares: Standard Reddit engagement features

This interactivity is both an opportunity and a responsibility—you need to monitor and respond to engagement.

Conversation Ad Specs & Requirements

Technical specifications for creating conversation ads:

Headline Requirements

Specification	Requirement
Character Limit	100 characters (shorter than feed ads)
Best Practice	Under 80 characters for full visibility

Important: The 100-character limit is stricter than feed ads (150 characters). Plan your headlines accordingly.

Creative Specs

Conversation ads use the same image and video specifications as other Reddit ads:

Image Ads:

• Dimensions: 1080×1080 (1:1), 1080×1350 (4:5), 1920×1080 (16:9)
• File types: JPG, PNG
• Maximum size: 3 MB

Video Ads:

• Dimensions: Same as image
• File types: MP4, MOV
• Maximum size: 1 GB (512 MB recommended)
• Duration: Up to 15 minutes (15-30 seconds optimal)
• Thumbnail: 400×300 px, JPG/PNG, max 500 KB

Targeting Options

Conversation ads support standard Reddit targeting:

• Subreddit targeting
• Interest targeting
• Keyword targeting
• Device and location targeting
• Custom audiences and retargeting

Best Practices

Making conversation ads work requires understanding Reddit's discussion culture:

1. Match the Conversation Tone

Your ad appears in a discussion context. Corporate-speak stands out negatively.

Do:

• Use natural, conversational language
• Ask questions that invite response
• Share genuinely helpful information
• Acknowledge that you're an advertiser (Reddit users respect transparency)

Don't:

• Use aggressive sales language
• Lead with your product features
• Ignore the discussion context
• Post generic promotional content

2. Add Genuine Value

The best conversation ads feel like they belong in the discussion.

Value-adding approaches:

• Share useful tips related to the discussion topic
• Provide educational content users can apply
• Offer resources that help with common problems
• Present interesting perspectives or data

Example: Instead of "Buy our project management software today!" try "Struggling with team deadlines? Here are 5 tips that helped our clients cut missed deadlines by 40%..."

3. Enable and Monitor Comments

Conversation ads get comments. This is expected and healthy.

Comment management strategy:

• Respond to questions within hours (not days)
• Engage constructively with criticism
• Thank users for positive feedback
• Never argue or get defensive

Pro tip: Assign someone to monitor conversation ad comments during business hours. Ignored comments look bad; thoughtful responses build trust.

4. Use Shorter Headlines

With only 100 characters, every word counts.

Headline optimization tips:

• Lead with the benefit or hook
• Remove unnecessary words
• Focus on one clear message
• Test multiple variants (3-5 recommended)

Example headlines:

• ✅ "Cut your meeting time in half with async video updates" (52 chars)
• ✅ "Why 73% of developers switched to this code editor" (50 chars)
• ❌ "Discover how our revolutionary software platform can transform your workflow and save you time" (93 chars—too long and too promotional)

5. Match Content to Communities

Conversation ads should feel native to each subreddit's culture.

Customization approach:

• Research the subreddit's typical discussion style
• Note common terminology and in-jokes
• Understand what content types perform well
• Create subreddit-specific creative variants

A conversation ad in r/programming should sound different than one in r/smallbusiness, even for the same product.

Examples of Great Conversation Ads

What successful conversation ads look like in practice:

Educational Content Approach

Brand: SaaS company targeting r/entrepreneur Headline: "The pricing mistake that almost killed our startup" Creative: Video sharing a genuine story of pricing lessons learned Result: High engagement, positive comments, leads to case study content

Why it works: Honest, educational, relevant to the community's concerns

Problem-Solution Approach

Brand: Productivity tool targeting r/productivity Headline: "How I finally stopped forgetting follow-ups" Creative: Image with simple tip that mentions (but doesn't push) the tool Result: Comments sharing additional tips, organic product interest

Why it works: Addresses real pain point, provides value before selling

Question-Based Approach

Brand: Cybersecurity company targeting r/sysadmin Headline: "What's your biggest security headache in 2026?" Creative: Simple branded image inviting discussion Result: Comments generate insights while driving awareness

Why it works: Invites participation, feels like genuine discussion

Data-Driven Approach

Brand: Marketing agency targeting r/marketing Headline: "We analyzed 1,000 ad campaigns. Here's what actually works" Creative: Infographic with key findings Result: Saved and shared widely, drives traffic to full report

Why it works: Provides unique value, positions brand as expert

When to Use Conversation Ads

Conversation ads aren't right for every campaign. Here's when they excel:

Best Use Cases

1. Brand Building & Trust

• When you need to establish credibility in a community

When to Avoid Conversation Ads

1. High-Volume Lead Generation

• Feed ads typically drive more clicks

2. Time-Sensitive Promotions

• Limited-time offers need broader reach
• Feed placement reaches more users faster

3. Products Requiring Less Explanation

• Simple consumer products may not need discussion

4. Brands Unable to Respond to Comments

Performance Comparison: Conversation vs. Feed

How do conversation ads perform compared to feed placement?

Engagement Metrics

Based on advertiser reports and case studies:

Metric	Conversation Ads	Feed Ads
CTR	Lower volume	Higher volume
Engagement Rate	Higher	Lower
Comment Volume	Significantly higher	Lower
Brand Sentiment	Often more positive	Neutral
Cost Per Engagement	Often lower	Varies

Example Performance Data

One advertiser shared comparative data with similar spend:

• Conversation placement: 217 engagements, higher quality interactions
• Feed placement: Higher impressions, lower engagement rate

Strategic Implication

Conversation ads optimize for quality over quantity. They work best when:

• Engagement value exceeds raw traffic value

Frequently Asked Questions

What's the difference between conversation ads and feed ads?

Conversation ads appear within comment sections when users click into a post to read discussions. Feed ads appear while users scroll the main feed. Conversation ads have shorter headline limits (100 vs. 150 characters) and receive more direct engagement (comments, votes).

Should I enable comments on conversation ads?

Yes, comments are core to the conversation ad experience. Users expect to interact with content in discussion threads. Disabled comments look unusual in this context. The key is actively monitoring and responding to comments.

What headline length works best for conversation ads?

While the limit is 100 characters, aim for 80 characters or fewer for full visibility across all devices. Lead with your hook or value proposition, and cut unnecessary words.

How do conversation ads affect brand perception?

When done well, conversation ads significantly boost brand trust because they demonstrate willingness to engage directly with the community. However, poorly executed ads (ignored comments, aggressive sales language) can damage perception.

Are conversation ads more expensive than feed ads?

Costs vary by targeting and competition, but CPM/CPC rates are often comparable. Conversation ads typically deliver fewer impressions but higher engagement rates, so cost-per-engagement can be lower.
