Reddit Ads Guide
Reddit Ads Examples: All 9 Types, Specs & What Works
Most pages about Reddit ads examples show five screenshots and call it research. This one covers all nine official ad formats, each with a campaign I could actually verify. The full 2026 spec reference is here too, pulled from Reddit's help center in July, plus a section nobody else writes: ads that failed and why. It's the creative chapter of my full Reddit advertising guide, for the day you stop reading about Reddit ads and start building one. I've run these campaigns and shipped a Reddit marketing product, so where a format is overpriced or overhyped, I'll say so.
What do Reddit ads look like?
Reddit ads look almost identical to regular Reddit posts. They show up in the feed and inside comment threads, marked with a small "Promoted" label where a username and subreddit would normally sit. Everything else matches organic anatomy: headline, media, vote buttons, and, if the advertiser allows it, a live comment section.
That "Promoted" tag is the only reliable giveaway, and it's doing a lot of work. Redditors scan for it reflexively. There are two placements, per Reddit's ad unit specs: feed (Home, Popular, and community feeds) and conversation (inside comment threads, catching people who arrive from Google). Reddit recommends running both, and for once I agree with the platform's upsell.
The design consequence is blunt. Ads that inherit post anatomy (plain headline, native-feeling image, comments on) get read; ads that look like display banners dropped into the wrong website get scrolled past. Your creative isn't competing with other ads here. It's competing with someone's favorite shitposts.
The 9 types of Reddit ads (with examples)
Reddit's official format list breaks down into self-serve formats anyone can buy in Ads Manager and managed formats that require a Reddit sales rep and a serious budget.
1. Promoted Posts
The original format: take an existing organic post and pay to push it into more feeds. Jack Daniel's ran native-style promoted content in r/cocktails and r/country, recipes and whiskey culture rather than product shots, and Recho's brand roundup credits the approach with $5 million in incremental holiday sales. One wrinkle from Reddit's own docs: they now recommend building free-form ads in Ads Manager instead of promoting posts directly, because promoted posts have thumbnail display issues. The upside they don't mention is that a promoted post keeps its existing upvotes and comment history, which no other format gets.
2. Image ads
Start here. Every account I've run began with image ads, and most never needed to graduate past them. The format itself: one image, one headline, one destination URL, optional comments. Alchemy, a streaming platform that tested formats relentlessly, found plain images beating their video creative, with Recho's roundup putting their acquisition cost about 50% below their other paid channels. Screenshots outperform studio photography here, mostly because a cropped product screenshot with a specific claim reads like a post while lifestyle photography spends its 3 MB saying nothing.

3. Video ads
Feed videos autoplay muted, so the first three seconds carry the whole ad. The reference campaign is OREO's Star Wars collaboration: snappy 6- and 15-second branded cuts that treated the fandom like an audience, not a target, driving a 10.2-point ad awareness lift per Reddit's success stories. For direct response, I'd validate the message with a cheap image ad before commissioning any video. Specs allow 2 seconds to 15 minutes; ignore the ceiling, since Reddit itself recommends 5–30 seconds and even that's generous for a muted feed.
4. Carousel ads
Two to six swipeable images under one headline, each card carrying its own destination URL and an optional 50-character caption. Static cards go up to 20 MB (GIFs cap at 3 MB), and Reddit strongly recommends one aspect ratio across every card.
5. Conversation ads
Technically a placement, not a creative type: your ad appears inside comment threads, where people land from their feed or straight from a Google search. Lenovo's conversation placement delivered, per Search Engine Land's coverage, a 40% lower CPA than its 2023 campaign average and a 30% year-over-year improvement. Reddit's own data in the same piece claims feed-plus-conversation campaigns see 83% higher brand awareness than feed alone. It's a checkbox in campaign setup, and I check it by default.
6. Dynamic Product Ads
Reddit's catalog format: upload a product feed, install the pixel, and Reddit assembles ads automatically for retargeting or prospecting. Tushbaby used DPA with AI-generated creative variants from Genus to retarget parenting-subreddit browsers, a campaign Reddit turned into an official case study (Genus AI writeup) alongside their reported +84% ROAS in Reddit's success stories. OnlineLabels hit 13x ROAS with retargeting on the same page. E-commerce only, and only useful once you've uploaded a catalog feed and the Reddit pixel has collected some browsing data.
7. Free-form ads
The format closest to an actual Reddit post: a headline plus up to 40,000 characters of rich body text, 20 images, and 5 videos, per Reddit's free-form specs. This is the one I'd push B2B advertisers toward, because a well-written free-form ad is functionally a promoted essay, and Reddit is among the last places on the internet where people voluntarily read. Brands almost never publish free-form case studies, so filter the Ads Inspiration Library by format to see live ones instead of trusting anyone's screenshots, mine included.
8. Takeover & Category Takeover
Managed placements where you own a surface for a day: the front page, or every community in a content category. OREO's Star Wars push combined auction ads with a Sci-Fi, Horror & Comic category takeover to own the exact fandom the cookie launch targeted, and it's the sharper way to buy this format, since a category is a self-selecting audience rather than a demographic guess. Skip, the Canadian food delivery service, went broader and bought the front page outright, pairing the takeover with carousel creative for a 9.8-point brand awareness lift per Superside's examples roundup. Pricing starts around $100K+ per day, according to Recho's pricing guide, and the banner components carry their own tight specs, 150 KB files at 300x600 or 300x250. If you have to ask whether it's worth it, it isn't yet.
9. First View
Reddit's premium reserve format: your brand gets the first ad impression of a user's session on the Home and Popular feeds, sold through the managed ad-types lineup. I couldn't find a single named, verifiable First View case study with public numbers, which tells you something about who buys it and how they measure it. It exists for movie premieres, console launches, and CMOs with awareness OKRs. Fine. Just don't benchmark your $2K test budget against it.
Reddit ad specs: complete 2026 reference
Every number below comes from Reddit's official spec pages on business.reddithelp.com, checked July 2026. One universal rule first: headlines allow 300 characters, but Reddit recommends staying under 100, or 80 if truncation worries you. It should. Truncation depends on device and font size, and a headline that dies mid-sentence looks broken.
Text limits (all auction formats)
| Element | Limit | Notes |
|---|---|---|
| Headline | 300 characters | Recommended ≤100; safer ≤80. Required |
| Destination URL | 268 characters | Per carousel card for carousels |
| Display URL | 100 characters | Must match destination domain |
| Carousel caption | 50 characters | Optional, one per card |
| Free-form body | 40,000 characters | Feed shows 3–6 lines of plain text |
| Call to action | Preset list | 23 options, from "Apply Now" to "Watch Now" |

Takeover components (top banner, sticky banner, vertical video, video spotlight) carry separate managed-buy specs, mostly 150 KB banners and 9:16 videos of 5–30 seconds; they're in the same ad unit spec doc if you've got the budget that makes them relevant.
Where to find more Reddit ad examples: the inspiration library
Reddit quietly ships the thing people search "reddit ads library" hoping to find: the Ads Inspiration Library, a browsable collection of the platform's most successful active ads from the past year. It lives at Creative > Ads Inspiration Library inside Ads Manager, and anyone with a free Reddit Ads account can open it, per Reddit's documentation.
You can filter by industry (sixteen categories, from Tech B2B to Gambling), budget tier, format, and objective. Each ad shows its details plus AI-generated notes on the three tactics it used, and, the genuinely useful part, a live link to the actual post so you can read the comments and vote counts.

Two caveats. It only shows winners, so you'll learn nothing about what bombed. And "successful" is Reddit's label with no performance numbers attached — you can't tell a 2% CTR from a 0.2% one.
What makes a Reddit ad feel native (good vs bad teardown)
Take two real patterns you'll see in the wild within five minutes of scrolling.
The good one looks like Alchemy's winning approach or half the Tech B2B tab in the inspiration library: a plain-language headline with a specific number ("We cut our stripe disputes 70%, here's the dashboard"), a cropped product screenshot for a thumbnail, comments on, and a founder replying to the skeptics within the hour. The headline sounds like a person. The screenshot proves the claim. The comment replies convert the fence-sitters, because on Reddit the comments ARE the landing page.
The bad one you already know. Title-case slogan, exclamation point, stock photo of people laughing at a laptop, comments disabled. Each choice fails separately: the slogan signals "ad" in the first four words, the stock photo has no information in it, and killing comments tells redditors you expected to lose the argument. They notice. Tone-deaf promoted posts get screenshotted and reposted for mockery, and the repost usually travels further than the ad did.
I keep the complete checklist, targeting included, in my Reddit ads best practices guide.
Reddit ads that failed (and why)
Three failure patterns, with receipts.
The minimum-bid trap. Two weeks and $100 at Reddit's $0.20 minimum CPC bought Moss Technologies exactly one conversion, a case documented in Zapier's Reddit ads review. Minimum bids buy leftover impressions from placements nobody else wanted. Compare Animoto in the same piece, paying $1.58 CPC at a $6.23 CPM and renewing the budget anyway.
Underfunded broad tests. A game developer's r/gamedev post-mortem of $250 spent over two weeks is required reading. Broad targeting spread a small budget across audiences that never got enough frequency to matter. Oddly, the write-up itself did fine; the post now ranks in Google for Reddit ads queries, ahead of several agency guides.
Corporate-speak creative. The most Reddit-specific failure. Ad copy that would be fine on LinkedIn gets downvoted, mocked in comments, or brigaded, and Reddit's ad system doesn't hide vote counts on promoted posts with comments enabled. When your ad's top comment is a takedown with 400 upvotes, you're paying CPM rates to distribute criticism.
Mock up the organic version first
Here's the cheapest QA process in advertising: before you spend a dollar promoting a post, strip the Promoted tag off in your head and ask whether it survives as a regular submission. If honest-you says it gets downvoted or ignored, the paid version fails too; the tag only lowers its odds. Test it concretely with our free Reddit post mockup tool: drop in your headline and creative, look at it rendered as a plain post, and let the cringe reflex do its job.
That test points at the bigger issue with paid. Ads rent attention: the day the budget stops, so do the impressions, while a decent organic thread keeps ranking in Google for years — Reddit shows up in roughly 37% of top-10 results — and keeps getting quoted by AI assistants answering buyer questions. The $250 gamedev post-mortem above is the working proof, still outranking the agency guides it embarrasses.
FeedHeat is our attempt to automate that side. The agent watches for subreddit threads where your buyers already are (someone asking "best baby carrier for bad backs?" in a parenting sub, say) and drafts a native-sounding reply — approve each one in review mode, or let the agent handle it. Tracking is built in, so you can see which threads keep collecting upvotes and climbing Google weeks later. If the organic math above made sense to you, it's worth twenty minutes of a demo.
Ads look native. Agents are native.
FeedHeat's agents write posts and comments that blend into each community, in real browser sessions on human-looking schedules — full autopilot, or review mode if you want eyes on every draft.
Frequently asked questions
What sizes do Reddit ads need to be?
For image ads, Reddit recommends 1440x1080 px (4:3) as the safest cross-device size, with 1080x1080 (1:1), 1080x1350 (4:5), and 1920x1080 (16:9) also supported. Max file size is 3 MB for images (JPG, PNG, or GIF). Carousel cards allow up to 20 MB for static images. Any aspect ratio technically works, but off-spec ratios get letterboxed, which looks terrible in the feed.
How long can Reddit video ads be?
Reddit video ads can run anywhere from 2 seconds to 15 minutes, per Reddit's official video specs. Nobody should use that ceiling. Reddit itself recommends 5–30 seconds, and in my experience the first 3 seconds decide everything because feed videos autoplay muted. Files must be MP4 or MOV (no ProRes), 1 GB max, at up to 30 FPS.
Can Reddit ads have comments?
Yes. Comments are optional on image, video, carousel, and free-form ads; you toggle them per ad. Most advertisers switch them off out of fear, which redditors read as a confession. If your product is solid and someone will actually reply within a few hours, leave comments on. An advertiser answering blunt questions in their own ad thread is the most convincing creative Reddit offers.
Where can I see examples of Reddit ads?
The fastest source is Reddit's own Ads Inspiration Library, found under Creative > Ads Inspiration Library in Ads Manager. Anyone with a free Reddit Ads account can browse it and filter by industry, budget, format, and objective, then open the live post to see real comments and votes. Beyond that, just scroll r/all logged out and note every post marked Promoted.
