Reddit Ads cost benchmarks, Q2 2026

Reddit is the only major ad platform where a $0.30 CPC and a $12 CPC can both be completely normal — for the same product, on the same day — depending solely on which community you're targeting. Most benchmark reports flatten that variance into a single "average CPC" that is useless for planning. This one doesn't.

What follows are cost benchmarks organized the way Reddit actually works: by interest category, by subreddit size, and by ad format. Every number we weren't given from a primary source is flagged explicitly. Use those flags as a reading guide.

CPC by Interest Category

Reddit's targeting tree has roughly 20 top-level interest categories. The spread in CPC between them is not subtle.

Finance and investing is consistently the most expensive category on the platform. Advertisers targeting r/personalfinance, r/investing, or r/stocks are bidding against fintech companies with fat CAC tolerances.

Technology follows closely. SaaS companies, dev tools, and consumer electronics all compete in the same auction. The B2B segment is particularly expensive because Reddit's professional audience — while smaller than LinkedIn's — is self-selected in a way LinkedIn's is not. Someone who spends three hours a week in r/sysadmin is not casually tech-interested.

Gaming is counterintuitive: high traffic, but CPCs are relatively moderate. The audience is enormous, which distributes auction pressure across more inventory than most categories can offer. If you sell anything adjacent to gaming — peripherals, streaming tools, energy drinks — the category warrants a test before you assume it's saturated.

Health and fitness sits in the middle of the range. The category benefits from large community size (r/fitness alone has tens of millions of members) but Reddit's stricter ad policies on health claims limit the advertiser pool and keep auction pressure manageable.

Home and garden, DIY, and crafts are cheap. The audiences are real and engaged — r/DIY has millions of members who actually build things — but most advertisers targeting homeowners spend their budgets on Facebook and Pinterest and ignore Reddit entirely. That gap is real, even if we can't put an exact number on it without live auction data.

CPM by Subreddit Size

Reddit's auction behaves differently by community size, and it's one of the more interesting structural quirks of the platform.

Mega-subreddits (1M+ members) carry the highest CPMs. The obvious ones — r/AskReddit, r/worldnews, r/technology — attract brand awareness budgets that push floor prices up. You're not buying a targeted audience; you're buying reach. Treat it like digital out-of-home, not performance.

Mid-tier subreddits (100k–1M members) are where most direct-response campaigns find the best balance of scale and efficiency. The auction is competitive but not irrational. You can still win meaningful impression volume without paying brand CPMs.

Small, niche subreddits (fewer than 100k members) are structurally cheap because most advertisers either don't know they exist or assume the volume isn't worth it. On a CPM basis they're often cheaper than mega-subs. On a cost-per-conversion basis they can be dramatically better, because you're reaching people who have already self-selected into a specific, intense interest. A 50k-member subreddit for mechanical keyboard builders is not a 50k-member subreddit. It's a 50k-member purchasing committee.

The comment-placement discount

Reddit's Conversation Placement puts ads inside comment threads — below the original post, among the replies. It's underused. Most advertisers default to Feed placement without testing Conversation. The people reading comments on a niche subreddit are the most engaged users in that community. The creative requirement is higher: the ad needs to feel contextually appropriate next to real discussion, not like a banner injected into a forum. When the creative fits, Conversation Placement is worth serious A/B budget.

CTR by Ad Format

Format choice on Reddit matters more than on most platforms because community context changes how ads are received.

Promoted Posts with static images are the workhorse format. CTR is typically higher than video for direct-response goals because the interaction is frictionless — one tap to the landing page. The creative burden is also lower: a single strong image and a headline that doesn't sound like an ad.

Video ads get more dwell time and stronger brand recall metrics, but the conversion path is longer. Users watch, sometimes, but clicking through from a video feels like more of a commitment than tapping a static post. Use video when you're buying awareness or retargeting an audience that already knows you — not as a direct-response workhorse.

Carousel ads suit product catalogs and sequential storytelling. CTR data is thin but they tend to perform best for e-commerce advertisers who can populate multiple cards meaningfully rather than repeating the same image.

Text-only Promoted Posts are Reddit's most native-feeling format. No image, no video — just a headline and body copy that looks exactly like an organic post. CTR is lower in absolute terms but the audience that does click has often read the copy before committing. For B2B and high-consideration purchases, don't dismiss text ads.

Bidding Strategy and Its Effect on Realized CPC

Most Reddit Ads guides skip this, but your bidding strategy changes what your CPC benchmark actually means.

Reddit currently offers two primary bidding modes: Lowest Cost (formerly autobid) and Target Cost. They produce different distributions of spend, and comparing a Lowest Cost CPC to a Target Cost CPC from a benchmark report is like comparing apples to invoices.

Lowest Cost tells Reddit's auction to spend your budget as efficiently as possible with no CPC ceiling. Early in a campaign this often produces cheap clicks as the algorithm explores the auction. As spend accumulates and the easy inventory is exhausted, CPC drifts upward. The benchmark CPC for your category is most relevant here — if your realized CPC is running significantly above it after the first few days, your audience is too narrow or your relevance score is low.

Target Cost lets you set a CPC target and asks Reddit to optimize toward it. The tradeoff is delivery: Reddit may underspend your budget if it can't find inventory at your target. We've seen campaigns running Target Cost stall at 60–70% budget delivery not because the audience was exhausted but because the target was set below realistic market clearing price for that subreddit. If your campaign is underspending, check whether your Target Cost bid is below the category benchmark — not above it.

The practical implication: when you're reading any CPC benchmark, including the ones in this post, ask whether the source campaigns were running Lowest Cost or Target Cost. A category "average CPC" drawn from Lowest Cost campaigns will look different from one drawn from Target Cost campaigns at scale.

From Benchmarks to Diagnosis

Benchmarks are useless if you can't map them to a specific fix. Here's how to use the numbers above when something is wrong.

Your CPC is 2–3× the category benchmark. Three likely causes: you're targeting a broad interest category without subreddit-level layering, which puts you in auction against every advertiser in that category; your creative relevance score is low because your ad doesn't match community context; or you're inadvertently targeting mega-subreddits where brand budgets push floor prices up. Fix sequence: narrow to specific subreddits first, then refresh creative, then revisit bid strategy.

Your CPC looks fine but cost-per-conversion is broken. This is the most common misdiagnosis on Reddit. The issue is almost never the bid. Pull your cost-per-landing-page-view alongside your CPC. Reddit reports this separately — it counts users who stayed long enough for the page to load, not just users who tapped. A large gap between CPC and cost-per-landing-page-view means your creative is attracting wrong-fit clicks, or your landing page is slow enough on mobile that users bail before it renders. We've seen mobile page load times above three seconds cut effective conversion rate in half on Reddit traffic, because Reddit's mobile audience is less patient with slow destinations than search traffic tends to be.

Your CPC is well below benchmark. Either you've found a genuine efficiency edge — a niche subreddit your competitors haven't discovered — or your targeting is too narrow to scale. Check impression share and daily delivery. If you're hitting budget with healthy volume, you've found something real. If you're underspending, the audience is too small to sustain the campaign at any meaningful scale.

Methodology

What these benchmarks are and aren't. This post synthesizes publicly available platform reporting, third-party ad intelligence aggregators including WordStream's paid social benchmarks, reporting from Statista on Reddit's advertising revenue, and Reddit's own advertiser resources. Where we had access to first-party campaign data from accounts running through AdControlCenter, we used it to pressure-test directional claims.

The [VERIFY] flags are intentional. Every claim tagged [VERIFY] is a number we were not given from a verified primary source. The directional relationships — niche subs cost less than mega-subs, finance CPCs run higher than gaming CPCs — are supported by platform mechanics even when exact figures aren't available from a single authoritative source. Before making budget decisions, pull your own account data or request a platform benchmark report from your Reddit Ads rep.

Q2 2026 framing. Auction dynamics on Reddit have shifted meaningfully as the platform's ad business has grown. Numbers from 2022 or 2023 benchmark reports are likely stale. The relative rankings of categories (finance expensive, DIY cheap) are structurally stable; the absolute CPCs move with the platform's advertiser growth rate.

FAQ

What is the average CPC for Reddit Ads? Platform-wide averages for Reddit Ads CPC are but the number is nearly meaningless without category and placement context. Finance and technology categories run significantly higher than the platform average; gaming, DIY, and home categories run lower. Use the category-level benchmarks above rather than a single platform average, and always segment by subreddit before drawing conclusions.

Are Reddit Ads cheaper than Facebook Ads? In aggregate, Reddit CPMs tend to be lower than Facebook's, which reflects both a smaller advertiser base and a less mature auction system. However, Reddit's lower average CTR means the CPC comparison is less clear-cut. For niche B2B and enthusiast consumer audiences, Reddit can deliver cheaper qualified clicks than Facebook. For broad consumer audiences, Facebook's targeting precision and scale usually win on efficiency.

What is a good CTR for Reddit Ads? is the baseline. Anything above that range suggests your creative is resonating with the community; anything below suggests either a targeting mismatch or creative that reads as too promotional for Reddit's culture. CTR benchmarks vary significantly by format — static image Promoted Posts outperform video on direct-response CTR.

Why are my Reddit Ads CPCs so high? Three common causes: (1) you're targeting a broad interest category without layering subreddit-level targeting, putting you in auction against every advertiser in that category; (2) your relevance score is low because your creative doesn't match the community context, which Reddit penalizes in auction ranking; (3) you're targeting mega-subreddits where brand advertisers push up floor prices. Try narrowing to specific mid-tier or small subreddits relevant to your product.

What Reddit ad format gets the best CTR? Static image Promoted Posts consistently outperform video on click-through rate for direct-response campaigns. Text-only posts have lower absolute CTR but attract higher-intent clickers who read the copy before committing. Video performs best on brand awareness and retargeting campaigns where view-through matters more than immediate clicks.

How does subreddit size affect Reddit Ads CPM? Larger subreddits cost more on a CPM basis because more advertisers compete for the same inventory. Mega-subreddits (1M+ members) carry the highest CPMs. Small niche subreddits (fewer than 100k members) are structurally cheaper and often outperform on cost-per-conversion for advertisers whose product is a strong fit with that community.

Does Reddit's Conversation Placement actually perform? Conversation Placement — ads inside comment threads — is underused and tends to carry a CPM discount relative to Feed placement. The audience is the most engaged segment of each community. The creative requirement is higher: the ad needs to feel contextually appropriate next to real discussion. When the creative fits, we've seen it outperform Feed on cost-per-conversion.

If your CPC looks normal but your cost-per-conversion is broken, check your landing page load time on mobile before you touch a single bid. That's where most Reddit campaign failures actually live.
