What This Reddit Ads Mockup Generator Does
A Reddit ads mockup is a visual preview of how your promoted post or organic content will appear in the Reddit feed. It simulates the exact layout, text truncation, voting controls, awards, and CTA buttons that real Reddit posts display — without requiring you to launch a campaign or spend any budget.
This free tool lets you preview and customize every aspect of your Reddit ad, including:
- Post Title — up to 300 characters, displayed in semibold
- Post Body — up to 500 characters with automatic truncation and "read more" link
- Subreddit Name — set the community context (r/subreddit format)
- Username — displayed as u/username in the post header
- Media Image — upload an optional image for visual posts
- CTA Button — customizable call-to-action for promoted posts
- Engagement Metrics — upvotes, comments, awards, and time posted
- "Too Salesy" Warning — flags promotional language that may turn off Reddit users
Promoted Posts vs Organic Posts on Reddit
Understand the key differences between paid and organic content on Reddit and when to use each.
Promoted Posts
- Appear in feed with a "Promoted" badge
- Targeted by subreddit, interest, location, and device
- Include a CTA button (Learn More, Shop Now, etc.)
- Charged per impression (CPM) or per click (CPC)
- Best for brand awareness, traffic, and conversions
Organic Posts
- Regular community posts without promotion badge
- Ranked by Reddit's algorithm based on engagement
- No CTA button — engagement drives visibility
- Free to post, but require community trust
- Best for community building and authentic engagement
Why Subreddit Context Matters for Ad Performance
Reddit is a collection of thousands of niche communities, each with its own culture, tone, and expectations. Matching your ad copy to the subreddit context is critical for performance.
Community-First Messaging
Reddit users respond best to ads that feel native to their subreddit. A post in r/technology should sound different than one in r/smallbusiness. Use our Quick Fill presets to set the right context and tone.
Avoid the Downvote Risk
Overly promotional language can backfire on Reddit. Enable the "Too Salesy" warning in our tool to check your copy for phrases that commonly trigger negative reactions from Reddit's famously skeptical user base.

Reddit Advertising Glossary
Key terms you should know when creating Reddit ads.
Promoted Post
Reddit's native advertising format. Promoted posts appear in users' feeds alongside organic content, labeled with a 'Promoted' badge. They support targeting by subreddit, interest, location, and device.
Subreddit
A community on Reddit focused on a specific topic (e.g., r/technology, r/marketing). Each subreddit has its own rules, moderators, and culture. Ads can be targeted to specific subreddits.
Karma
Reddit's point system based on upvotes and downvotes. Karma reflects a user's contributions to the community. Higher karma can indicate credibility, though it's not directly tied to ad performance.
Awards
Virtual badges that Reddit users can give to posts and comments they find valuable. Awards like Gold, Silver, and community-specific awards increase post visibility and perceived quality.
Native Advertising
Advertising that matches the form and function of the platform it appears on. Reddit promoted posts are native ads because they look and behave like regular Reddit posts.
Brand Safety
Measures to ensure ads appear in appropriate contexts. Reddit offers subreddit-level targeting and blocklists to control where your ads appear and avoid controversial content.
Community Guidelines
Rules set by subreddit moderators and Reddit itself. Ads that violate community norms or guidelines risk negative engagement, downvotes, and user backlash.
Downvote Risk
The potential for Reddit users to downvote your ad, reducing its visibility and perceived quality. Overly promotional, off-topic, or low-quality ads are most at risk of being downvoted.
