How to Run UGC Video Ads on Reddit Ads in 2026

Reddit is one of the most underused paid channels for ecommerce brands running UGC video ads. While TikTok and Meta dominate the conversation, Reddit's community-first structure gives you something rare: a platform where users are actively researching purchases, comparing products, and trusting peer recommendations. Running UGC video ads on Reddit Ads taps directly into that mindset — if you get the creative and targeting right.

This guide covers how to set up, target, and optimize UGC video ads inside Reddit Ads Manager, with specific advice on creative formats, specs, and what actually moves the needle.

Why Reddit Deserves a Spot in Your UGC Ad Strategy

Reddit's user base is intent-driven in ways most social platforms aren't. People browse subreddits to solve problems, find recommendations, and research purchases before buying. A well-made UGC video ad — one that feels native to the feed — can intercept that research phase rather than compete with it.

Reddit also offers subreddit-level targeting, which means you can place a UGC ad directly inside communities where your ideal buyer is already active. Selling running gear? Target r/running. Selling a productivity tool? Hit r/productivity or r/entrepreneur. That granularity is hard to replicate on other platforms.

The tradeoff is real: Reddit's audience is one of the most ad-skeptical communities on the internet. Pushy, polished creative gets scrolled past or downvoted. Authentic, lo-fi UGC video — the kind that could plausibly have been posted organically — outperforms brand-produced content by a significant margin here.

Setting Up a Reddit Ads Campaign for UGC Video

Reddit Ads uses a three-tier structure: Campaign → Ad Group → Ad.

At the campaign level, choose your objective. For UGC video ads, the most relevant options are:

• Video Views — optimizes delivery toward users likely to watch
• Conversions — optimizes for downstream actions like purchases or signups (requires the Reddit Pixel installed on your site)
• Traffic — sends users to a landing page, useful for top-of-funnel or retargeting flows

Install the Reddit Pixel on your site before launching conversion campaigns. Without it, Reddit has no signal to optimize against and your cost-per-action will be unpredictable. At the ad group level you define targeting, schedule, and budget. At the ad level, you upload your creative and write the headline and caption copy.

Which UGC Video Formats Work on Reddit

Not every UGC format translates equally to Reddit. The platform rewards content that feels like something a real person would genuinely post or recommend in a thread.

Reaction and testimonial-style videos

A person speaking directly to camera about a product problem they solved mirrors how Redditors write recommendation posts. This format is low-barrier and high-trust. If you're producing these at scale without coordinating real creators, AI-generated reaction-style video ads replicate this format efficiently across multiple creative angles.

Tutorial and how-to videos

Reddit communities deeply value practical, educational content. A short video that shows exactly how a product works — step by step — fits the cultural expectation of subreddits built around shared knowledge. Tutorial-style video ads built with AI are a scalable way to produce this format across multiple subreddit audiences with different vocabulary and pain points.

Storytime and narrative formats

"I tried X for 30 days" or "Here's what happened when I switched to Y" stories perform well because they mirror the personal anecdote posts that get traction organically on Reddit. Keep them under 30 seconds and front-load the tension.

What to avoid

Heavily produced, brand-polished video. Ads that feel like TV commercials stand out immediately as paid content, and Reddit users disengage fast. If it looks like something a brand filmed in a studio, it won't survive the feed.

Reddit Video Ad Specs

Before uploading, confirm your UGC video meets Reddit's current technical requirements:

• File format: MP4 or MOV
• Max file size: 1 GB
• Recommended length: 15–30 seconds
• Aspect ratios: 1:1, 4:5, 9:16, 16:9 — 1:1 and 9:16 take up more mobile feed space
• Sound: Off by default — captions are not optional

The sound-off default matters. If your UGC ad relies entirely on spoken audio, a large share of viewers will miss the message. Burn captions directly into the video file, or engineer a strong visual hook in the first two seconds that communicates value without any audio.

Targeting Strategy: Subreddits vs. Interests vs. Keywords

Reddit gives you three primary targeting levers:

Community (subreddit) targeting

The most precise option. You choose specific subreddits where your audience congregates. Communities must meet a minimum size threshold to be targetable, so very small niche subreddits may not be available. Research where your product category gets discussed organically — check what subreddits appear in Google searches for your product type or problem keywords.

Interest targeting

Broader than subreddit targeting. Reddit groups users by behavior across categories like Shopping, Technology, or Health & Fitness. Use this to scale once subreddit targeting has validated a winning creative — don't start here.

Keyword targeting

Targets users based on keywords they've recently engaged with in posts or comments. Useful for intent-based targeting: someone who just commented in a thread about "best protein powder" is a warmer lead for a supplement brand than a general fitness interest audience.

For most DTC brands starting on Reddit, subreddit targeting is the right entry point. Match the tone and language of each subreddit in your ad copy — the same UGC video that works in r/fitness may need different framing for r/keto or r/loseit.

Budgeting, Bidding, and Creative Volume

Reddit's CPMs are generally lower than Meta or TikTok for comparable audiences, but the platform has less optimization infrastructure, so don't expect the same algorithmic efficiency from day one.

A practical starting framework:

1. Start with a $30–$50 daily budget per ad group to accumulate enough data to optimize
2. Use CPM bidding initially to understand impression costs and video view rates
3. Shift to conversion bidding once you have a proven creative and sufficient Pixel data
4. Run at least 3–4 UGC video variants per ad group to give Reddit's system options and identify which creative angle resonates

Testing multiple creative variants quickly is as important on Reddit as on any other paid channel. Maintaining high creative testing velocity lets you identify which UGC angles work for specific subreddit audiences before committing significant budget to scale.

Measuring Reddit UGC Ad Performance

Reddit's native reporting covers impressions, video views, view rate, clicks, and — with the Pixel set up — conversions and ROAS. But last-click ROAS gives you an incomplete picture on Reddit, where users frequently research and then convert through a different channel days later.

Also track how Reddit traffic behaves on-site: time on page, pages per session, and add-to-cart rate give you a fuller signal on whether your UGC creative is attracting the right buyer intent. For a broader framework on evaluating creative effectiveness across channels, measuring UGC ad performance beyond ROAS covers the metrics that actually indicate whether a creative is working — not just whether it closed last-click.
