The Complete Guide to Reddit Ads: What Works, What Doesn’t, and How to Use the Platform Effectively

Reddit has been unusually loud lately and not because of another chaotic AMA or a rogue meme. It’s because the platform is actively trying to reposition itself as a serious advertising opportunity. You might even have seen their own ads appear on Instagram, YouTube, or TikTok. Yes… Reddit advertising about advertising.

It’s easy to scroll past the noise, but if you’re running paid media, you shouldn’t. Behind the chaos, cat gifs and legendary comment threads sits a platform that’s quietly evolving into one of the most interesting opportunities for brands that want real conversations, real engagement, and genuine community insight.

This guide breaks down what makes Reddit different, the formats that actually work, how to approach the platform without panicking, and whether it deserves a place in your media mix.

What Makes Reddit Different

Reddit isn’t your typical social media platform. It’s built around tens of thousands of micro-communities (subreddits) where people gather around specific passions, coffee, skincare, DIY, crypto, fitness, gaming, spreadsheets… the list goes on.

These aren’t passive “likes.” Subreddits are deep rabbit holes where users debate, compare, review, and recommend with brutal honesty you simply won’t find elsewhere.

On Meta or TikTok, you target people based on who they are, demographics, behaviours, algorithm-predicted interests.On search engines like Google, Bing or Perplexity, you target what people want their active intent.

Reddit sits comfortably in the middle. You target people based on what they’re obsessing over right now, inside communities where they’re already discussing your category with strangers.

Instead of “25 - 45-year-olds who like coffee,” you can appear directly inside r/Coffee, where users are passionately debating grinder burrs and water ratios.

It’s not demographic-first.

It’s not pure intent-first.

It’s interest-first, in the most literal sense.

And when you show up in the right subreddit at the right moment, your ads stop feeling like ads, they become part of the conversation.

Why Reddit Ads Matter Right Now

Reddit has quietly levelled up and most advertisers haven’t caught on yet. While Meta is juggling signal loss and Google is reinventing search every quarter, Reddit has been rebuilding its ad ecosystem into something far more powerful, targeted, and community-driven.

The Ad Manager is cleaner and easier to use. Targeting is smarter, with AI helping you reach users who behave like your ideal subreddit audiences, even if they’re not visibly active there. New formats prioritise authenticity and contextual fit rather than interruption.

Retail and eCommerce brands now have access to Dynamic Product Ads, full catalogue support, and SKU-level personalisation. And Reddit is already testing interactive formats , quizzes, playable elements, mini-experiences, designed for an audience that loves participating, not just scrolling.

Here’s the real opportunity: 

Reddit is still massively under-used compared to its cultural influence.

While other platforms fight for shrinking attention, Reddit remains one of the few places where ads can still feel human, helpful and genuinely native.

Brands who show up now gain three major advantages:

• Lower competition

• More authentic engagement

• Honest, high-signal feedback you cannot buy anywhere else

But, as with anything on Reddit, the format you choose matters. Get it wrong and you’ll stand out for all the wrong reasons. Get it right and you blend straight into the community.

The Ad Formats You Actually Need to Know About (And What Works)

Reddit offers far more creative flexibility than many advertisers expect, but each format behaves differently, and understanding the basics is essential before you even think about creative.

Here’s what each format actually is and how it’s used.

Promoted Posts

What it is:

A paid post that looks almost identical to an organic Reddit post. It appears inside subreddit feeds and the Home feed, marked subtly as “Promoted.”

Where it appears:

• Subreddit feeds

• Home feed

• Desktop and mobile

How users interact:

Upvote, downvote, comment, share, save, just like a normal post, unless comments are disabled.

Why it works:

It blends in. When written in a Reddit-native tone, it feels like part of the community, not an ad.

Watch-outs:

If it sounds like “brand speak,” Redditors will either ignore it or call it out.

Image & Video Ads

What they are:

Single image or short video placements that appear natively within Reddit feeds.

Where they appear:

• Subreddit feeds

• Home feed

• Popular feed

• Occasionally in search

How users interact:

Click-through to your landing page. Videos autoplay silently.

Why they work:

Clean, flexible and scalable. Ideal for awareness, demos and simple value propositions.

Watch-outs:

Overly polished creative feels off on Reddit, authenticity wins.

Carousel Ads

What they are:

A swipeable sequence of 2–6 images or videos, similar to Meta carousel ads.

Where they appear:

• Subreddit feeds

• Home feed

How users interact:

Users swipe horizontally before clicking through.

Why they work:

Redditors love detail. Carousels let you tell a story or compare products without overwhelming a single frame.

Watch-outs:

Every card needs value, avoid filler content.

Conversation Ads

What they are:

Promoted posts designed specifically to encourage replies and participation.

Where they appear:

• Subreddit feeds

• Home feed

How users interact:

They comment, often at length.

Why they work:

Reddit’s superpower is conversation. If your goal is insight or messaging testing, they’re incredibly effective.

Watch-outs:

You must moderate. Don’t run these if you won’t engage.

Product Ads & Dynamic Product Ads (DPAs)

What they are:

Ads generated from your product catalogue. Reddit dynamically shows the most relevant items based on behaviour and context.

Where they appear:

• Subreddit feeds

• Home feed

• Certain shopping surfaces

How users interact:

Clicks go directly to individual product pages.

Why they work:

Highly relevant for DTC brands with product ranges.

Watch-outs:

Categories with active subreddit communities perform best.

Takeover Formats

What they are:

Premium, high-impact placements that dominate the homepage or key categories.

Types include:

• Front Page Takeover

• Category Takeover

• Trending Takeover

Why they work:

Huge reach and visibility, perfect for launches.

Watch-outs:

Expensive. Definitely not subtle.

Interactive Ads (in testing)

What they are:

Playable, quiz-style or mini-experience ads currently rolling out to select advertisers.

Why they matter:

Redditors love participation. This format will likely become a standout performer.

Watch-outs:

Availability is still limited.

Who Reddit Works For (And Why)

Reddit isn’t the right platform for everyone, and that’s exactly what makes it valuable. It performs best when the audience, product and creative align naturally with Reddit’s culture and conversation style.

Strong fit

Brands with niche or enthusiast audiences

Gaming, tech, wellness, pet care, hobbyist products - if people already gather in subreddits about your category, you’re in the right place.

Products that spark curiosity or debate

If your product invites comparison, research or active discussion, Reddit becomes a high-quality discovery engine.

Brands with personality or a strong POV

If your brand voice is honest, transparent and has character, Redditors respond positively.

DTC brands with substance

USPs, founder stories, data-led value props, strong reviews - Reddit rewards depth and detail.

Struggles

Broad, mass-market “everyone” brands

Reddit thrives on specificity. Broad targeting dilutes results.

Highly polished or corporate brands

Anything that feels overly branded or formal stands out negatively.

Advertisers chasing last-click conversions

Reddit often influences mid–upper funnel behaviour, not immediate ROAS.

Brands unwilling to shift tone

You can’t copy/paste Meta creative. Reddit needs a different approach.

The Good, The Bad & The Downvotes

Reddit has huge upsides, but it comes with its own quirks. Understanding both helps you avoid surprises and set realistic expectations.

The good

High-intent, high-curiosity audiences

Users actively look for reviews, opinions and comparisons.

Lower competition

Ad inventory is far less crowded than Meta or Google.

Comments that actually mean something

Reddit provides honest, high-signal feedback no other platform offers.

Creative formats that reward authenticity

Ads that sound human perform significantly better.

The challenges

You need cultural awareness

Reddit has its own humour, norms and expectations.

Some subreddits are small

Scale varies. Relevance > reach.

Attribution isn’t straightforward

Expect influence across the journey, not last-click results.

Comments can be direct

It’s honest, sometimes blunt. but extremely useful.

Why this matters

If you embrace Reddit for what it is, a community-first platform, it can outperform traditional social channels for engagement and insight.But if you treat it like standard paid social and hope your Meta ads work here, you won’t get far.

How to Test Reddit Ads Without Panicking

Testing Reddit isn’t about throwing budget at it and hoping. It’s about understanding the culture, matching your tone and learning quickly.

1. Treat Reddit like research before ads. Study how people talk. Look at top posts. Understand humour, norms and expectations.

2. Match your format to your goal.

• Conversation > Promoted Posts

• Reach > Image/Video

• Comparisons > Carousel

• Retail > DPAs

• Launch > Takeover

  
  

3. Start with a meaningful test budget.

£200–£500 is enough to understand fit without overspending.

4. Write like a Redditor.

Human. Helpful. Honest.If your copy reads like an ad, rewrite it.

5. Expect comments & treat them as insight.

Reddit gives feedback other platforms hide.

6. Let campaigns settle.

Optimisation is slower than Meta. Assess trends, not day-one spikes.

7. Iterate lightly.

Small tweaks work best (headline, subreddit selection, image swaps).

8. Measure beyond last-click.

Reddit often influences:

• Branded search

• Session depth

• Repeat visits

• Community discussion

Don’t judge it as pure performance media, it’s broader than that.

🔹 Final Thoughts

Reddit isn’t the right platform for every advertiser and that’s exactly why it works so well for the brands that fit. When you respect the culture, align your creative with the community, and choose formats thoughtfully, Reddit becomes a powerful place to build trust, gather insight and start real conversations.

If your audience sits in a niche, if your product sparks discussion, or if your brand has a point of view worth sharing, Reddit is absolutely worth testing. Start small, learn fast and let the community guide what resonates.
