Reddit Ad Targeting: Complete Guide to Audience Options (2026)

Reddit's advertising platform has quietly become one of the most powerful targeting engines in digital marketing.

With 110.4 million daily active users spread across 100,000+ communities, Reddit offers something most platforms can't: audiences self-organized by interest, passion, and intent.

But here's the thing: Reddit ad targeting works differently than Facebook or Google.

The platform offers five distinct targeting methods—community, interest, keyword, custom audiences, and lookalike audiences—each with unique strengths. And recent 2025-2026 updates have made automated targeting 11% more effective at 10% lower cost per acquisition.

This guide breaks down every Reddit ad targeting option, shows you which delivers the best ROAS for different campaign goals, and gives you step-by-step instructions to set up high-converting campaigns.

Types of Reddit Ad Targeting Options

Reddit's advertising platform offers five core targeting methods that work independently or in combination:

Community (Subreddit) Targeting lets you place ads directly in specific subreddits where your audience already gathers. This is Reddit's most precise targeting option—and often the highest-converting.

Interest-Based Targeting reaches users based on their browsing behavior across Reddit's 152 interest categories. Reddit expanded from 66 categories in 2024 to capture more granular audience segments.

Keyword Targeting shows ads when users view posts containing specific terms. According to Reddit's internal data, keyword targeting increases click-through rates by 29.6% compared to interest targeting alone.

Custom Audiences let you retarget website visitors, upload customer lists, or engage users who interacted with your Reddit content. Retargeting on Reddit typically costs $2-5 per click versus $30+ on LinkedIn or Google.

Lookalike Audiences find new users who resemble your best customers. Reddit's lookalike modeling works exceptionally well because user behavior data is incredibly rich—every upvote, comment, and subreddit subscription signals intent.

Here's how these targeting types compare:

Targeting Type	Precision	Scale	Best For	Avg. CPC
Community (Subreddit)	Highest	Low-Medium	Niche products, high intent	$0.50-$3
Interest-Based	Medium	High	Broad awareness, discovery	$0.75-$4
Keyword	High	Medium	Intent-driven campaigns	$1-$5
Custom Audiences	Highest	Low	Retargeting, conversions	$2-$5
Lookalike	Medium-High	High	Scaling proven winners	$1-$4

Most successful campaigns layer multiple targeting types. For example, targeting r/entrepreneur (community) + "startup funding" (keyword) + business interests creates a highly qualified audience.

Let's break down each targeting method in detail.

Community (Subreddit) Targeting

Community targeting is Reddit's superpower—and the reason reddit business strategies work so well compared to other platforms.

Why it works: Subreddits are self-selected communities organized around specific interests, problems, or passions. When you target r/fitness, you're not guessing if users care about fitness—they've proven it by joining that community.

How to Set Up Subreddit Targeting

Setting up community targeting takes three steps:

Research relevant subreddits using Reddit's search or the Ads Manager's subreddit suggestions. Look for communities with 10,000+ members and active daily posts.
Add communities to your campaign in the Ads Manager under "Community targeting." You can add up to 100 subreddits per ad group.
Set your targeting radius to include similar communities. Reddit's "Expand" option automatically includes related subreddits with similar audiences.

Reddit's Ads Manager shows you subscriber count, growth rate, and user demographics for each subreddit before you add it. This data helps you prioritize communities with the right audience size and engagement.

Best Practices for Community Targeting

Start with 3-5 high-relevance subreddits rather than casting a wide net. Rise Vision, a digital signage company, used this approach to achieve 6x ROAS and a 77% reduction in cost per lead by targeting only r/smallbusiness, r/entrepreneur, and r/restaurantowners.

"We tested 20+ subreddits and found that three specific communities drove 85% of our conversions. Focusing budget on those three dropped our CPL from $42 to $9.50." — Rise Vision case study, Reddit for Business

Layer community targeting with other methods for better performance. Community + keyword targeting typically delivers 20-35% higher conversion rates than community targeting alone.

Monitor subreddit quality monthly. Communities can change rapidly—what was high-intent in January might be meme-filled by March. Use the analyze your Reddit profile tool to understand audience behavior patterns.

Avoid overly broad communities like r/AskReddit or r/funny unless you have massive budgets. These subreddits have huge reach but poor conversion rates because audiences aren't there with purchase intent.

Community targeting works best for niche products, B2B services, and any offer where audience passion drives conversion. If your product solves a specific problem a subreddit discusses daily, this is your highest-ROI targeting option.

For broader audience reach, interest-based targeting offers more scale.

Interest-Based Targeting

Interest targeting reaches users based on browsing behavior across all of Reddit, not just subreddit subscriptions.

Reddit's algorithm analyzes which subreddits users visit, which posts they engage with, and which topics they upvote to assign users to one or more of 152 interest categories.

How Reddit's Interest Categories Work

Interest categories span 15 major verticals including:

Business & Finance (investing, entrepreneurship, cryptocurrency, real estate)
Technology (programming, gaming, software, AI, gadgets)
Health & Fitness (nutrition, bodybuilding, mental health, running)
Entertainment (movies, music, television, books, anime)
Lifestyle (fashion, food & drink, travel, home improvement)

Reddit expanded interest categories from 66 to 152 in 2024 to capture more granular audience segments. According to Social Media Today, this expansion improved campaign precision by allowing advertisers to target "cryptocurrency investors" separately from "cryptocurrency news readers."

Each category has sub-interests. Under "Technology," you can target:

Software development
Artificial intelligence
Cybersecurity
Gaming hardware
Mobile apps

Targeting tip: Select 3-5 closely related interests rather than 10+ loosely related ones. Tight interest clusters deliver higher relevance scores, which lower your CPCs.

Interest Targeting vs. Community Targeting

Interest targeting offers 10-50x more scale than community targeting but with slightly lower precision.

If you target r/entrepreneur, you reach ~3 million subscribers. If you target the "Entrepreneurship" interest category, you reach 15+ million users who've shown interest in entrepreneurship content across dozens of subreddits.

Use interest targeting when:

Your product has broad appeal across multiple communities
You need volume for the top of your funnel
You're testing new audience segments
Relevant subreddits are too small (under 50,000 members)

Combine interest and community targeting for audience expansion that maintains quality. Start with high-performing subreddits, then layer in related interests to scale without sacrificing conversion rates.

Automated Interest Targeting

Reddit's newest feature, Automated Targeting, uses machine learning to optimize interest selection based on performance data.

According to Reddit for Business, automated targeting delivers 11% more conversions at 10% lower CPA compared to manual interest selection.

Here's how it works: You set campaign goals (traffic, conversions, video views), and Reddit's algorithm tests interest combinations, learns which drive results, and reallocates budget automatically.

Automated targeting works best for campaigns with:

Daily budgets above $50
At least 50 conversions per week (for optimization data)
Broad targeting goals (awareness, consideration)

For complete Reddit ads guide coverage, we recommend starting with manual interest targeting to learn which categories convert, then switching to automated targeting once you have performance data.

Keyword targeting takes precision even further by showing ads based on the exact content users are viewing.

Keyword Targeting on Reddit

Keyword targeting displays ads when users view posts or comments containing specific terms.

This is intent-based targeting at its finest—you're reaching people at the exact moment they're engaging with content about your topic.

How Reddit Keyword Targeting Works

Unlike Google Ads keyword targeting (which matches search queries), Reddit keyword targeting matches post titles, post content, and comment threads.

When someone browses a post titled "Best project management software for remote teams," your ad appears if you've targeted keywords like "project management software," "remote teams," or "collaboration tools."

Reddit offers three keyword match types:

Broad match shows ads when posts contain your keyword or close variations. Targeting "running shoes" also matches "marathon footwear" or "best sneakers for runners."

Phrase match requires posts to contain your exact phrase in order. Targeting "email marketing" matches "email marketing automation" but not "marketing through email."

Exact match shows ads only when posts contain your precise keyword phrase. Targeting "budget gaming laptop" matches only that exact phrase.

Start with phrase match for the best balance of reach and relevance. Broad match often triggers on tangential content, while exact match limits scale too much.

Setting Up High-Performing Keyword Campaigns

Reddit's keyword targeting increases CTR by 29.6% compared to interest targeting alone—but only when you select the right keywords.

Follow this process:

1. Start with 10-15 high-intent keywords. Focus on terms that signal buying intent or problem awareness, not generic browsing. "CRM for sales teams" beats "customer relationship."

2. Use Reddit's search function to preview which posts your keywords trigger. Search for your keyword, look at the top posts, and ask: "Would my ad be relevant here?"

3. Add negative keywords to prevent wasted spend. If you sell premium software, add "free," "open source," and "crack" as negatives.

4. Layer keywords with community or interest targeting. Targeting "vegan protein powder" + r/veganfitness performs better than keywords alone.

5. Monitor search term reports weekly. Reddit shows you which post titles triggered your ads. Pause keywords generating irrelevant impressions.

"We tested 50+ keywords for our B2B SaaS product and found that long-tail keywords like 'sales automation for small business' outperformed generic terms like 'CRM' by 3x on conversion rate." — Sprout Social Insights

Keyword targeting works exceptionally well for problem-solution products, software, courses, and high-consideration purchases. If your customers actively research solutions before buying, keyword targeting captures them at peak intent.

For remarketing to engaged users, custom audiences deliver the highest conversion rates.

Custom Audiences and Retargeting

Custom audiences let you target people who've already interacted with your brand—whether on your website, in your customer database, or through your Reddit content.

This is where Reddit advertising targeting becomes incredibly cost-effective. Retargeting costs $2-5 per click on Reddit versus $30+ on LinkedIn or Google Display Network.

Types of Custom Audiences on Reddit

Reddit offers four custom audience types:

Pixel-based audiences track website visitors using the Reddit Pixel (a JavaScript snippet you install on your site). You can retarget all visitors, specific page visitors, or users who completed specific actions.

Customer list audiences let you upload email addresses or mobile advertising IDs to target existing customers or leads. Reddit matches lists and creates targetable audiences.

Engagement audiences include users who upvoted, commented on, or clicked your Reddit ads or organic posts. This is powerful for reaching people who've shown interest in your content.

Video view audiences target users who watched your video ads for specific durations (25%, 50%, 75%, or 100% completion).

Setting Up Reddit Pixel Retargeting

The Reddit Pixel is your foundation for custom audiences.

Here's how to set it up:

1. Generate your pixel code in Reddit Ads Manager under "Pixels" in the Events Manager section.

2. Install the base pixel in your website's <head> section. If you use Google Tag Manager, Shopify, or WordPress, Reddit provides one-click installation options.

3. Set up event tracking for key actions like page views, add-to-cart, purchases, and sign-ups. Use Reddit's standard events or create custom events.

4. Create audiences based on pixel data. You can retarget users who visited specific URLs, took specific actions, or visited within specific time windows (7, 14, 30, 60, 90, or 180 days).

Retargeting strategy tip: Create funnel-based audiences with different messaging:

Users who viewed product pages but didn't purchase → highlight benefits and social proof
Users who added to cart but abandoned → offer limited-time discounts
Users who purchased → cross-sell complementary products

According to Reddit for Business, retargeting campaigns typically achieve 3-8x higher conversion rates than cold traffic campaigns while maintaining lower CPCs.

Customer List Targeting Best Practices

Customer list targeting works when you have at least 1,000 emails or mobile IDs. Reddit requires minimum audience sizes for privacy reasons.

Upload lists to:

Suppress existing customers from acquisition campaigns
Cross-sell new products to existing customers
Re-engage churned customers with win-back offers
Target high-value customer segments with premium products

Privacy note: Reddit hashes email addresses before matching, and you never see which individual users matched. You'll see audience size but not individual member data.

Combine custom audiences with organic reddit marketing services for a full-funnel approach. Use organic content to build engagement audiences, then retarget engaged users with conversion-focused ads.

To scale beyond your existing audiences, lookalike audiences find new high-potential users.

Lookalike Audiences on Reddit

Lookalike audiences (Reddit calls them "Lookalike Expansion") find new users who resemble your best customers.

Reddit's lookalike modeling is exceptionally powerful because user behavior data is so rich. Every upvote signals interest. Every comment reveals engagement patterns. Every subreddit subscription shows affinity.

How Reddit Builds Lookalike Audiences

You provide a source audience of 1,000+ users—typically your best customers, high-value pixel audiences, or engaged users—and Reddit's algorithm analyzes:

Which subreddits they visit
What content they engage with
Their commenting and posting patterns
Their upvoting and downvoting behavior
Demographic similarities

Reddit then finds new users who exhibit similar behavioral patterns across these dimensions.

Creating High-Performing Lookalike Audiences

The quality of your lookalike audience depends entirely on your source audience quality.

Follow these guidelines:

Use your best customers as the source. Upload a list of customers who've made multiple purchases, have high lifetime value, or have the lowest churn rates. Don't use all customers—use your best 10-20%.

Segment by behavior, not just conversion. Create separate lookalikes from "customers who purchased in first 7 days" versus "customers who purchased after 60+ days." These represent different user psychology.

Start with small lookalike sizes. Reddit offers 1%, 3%, 5%, and 10% lookalike audiences (% of total Reddit user base). Start with 1% for highest similarity, then expand as you prove performance.

Refresh lookalikes monthly. As your customer base grows and changes, rebuild lookalike audiences to reflect current customer patterns.

Layer lookalikes with interest or community targeting. A lookalike audience + "Technology" interest targeting performs better than lookalikes alone because you're adding topical relevance.

Lookalike audiences work best when you have:

At least 1,000 source users with similar characteristics
Conversion pixel data with 50+ conversions per month
Proven product-market fit (don't use lookalikes for unvalidated products)

Combine lookalike audiences with proven ad creative from your custom audience campaigns. If a message converts retargeting audiences, it'll often convert lookalikes as well.

Now let's put all these targeting methods together with proven best practices.

Best Practices for Reddit Ad Targeting

The most successful Reddit advertisers don't pick one targeting method—they orchestrate multiple methods across different campaign stages.

Here's the proven framework:

The Reddit Targeting Funnel Strategy

Top of funnel (awareness): Use interest-based targeting or automated targeting with broad interest categories. Goal: reach new audiences at scale and identify high-potential segments.

Middle of funnel (consideration): Use community + keyword targeting to reach users actively researching solutions. Goal: drive engagement and pixel users for retargeting.

Bottom of funnel (conversion): Use custom audiences (pixel retargeting, engagement audiences) and 1% lookalikes. Goal: convert high-intent users at lowest CPA.

Allocate 50-60% of budget to bottom-funnel retargeting, 30-40% to middle-funnel community/keyword campaigns, and 10-20% to top-funnel testing.

Advanced Targeting Combinations

Layer targeting types for precision without sacrificing scale:

Community + Keyword: Target r/entrepreneur + "startup funding" to reach entrepreneurs actively discussing funding (not just browsing casually).

Interest + Keyword: Target "Real Estate Investing" interest + "rental property" keyword to reach serious investors, not casual browsers.

Community + Custom Audience Exclusion: Target r/fitness while excluding pixel audiences who already converted. This prevents wasting budget on existing customers.

Lookalike + Interest: Build lookalikes from your best customers, then add interest targeting to focus lookalikes on relevant topic areas.

Testing and Optimization Framework

Run structured A/B tests to identify winning targeting combinations:

Week 1-2: Test 3-4 targeting methods independently (community vs. interest vs. keyword) with identical creative and offers. This isolates targeting performance.

Week 3-4: Test combinations of your best-performing methods (best community + best keyword, etc.).

Week 5+: Scale winners, cut losers, and test new audience segments using lookalikes or automated targeting.

Key metrics to track:

CTR (Click-Through Rate): Indicates ad relevance to the audience. Target 0.5%+ for cold traffic, 2%+ for retargeting.
CPC (Cost Per Click): Compare against benchmarks. Under $3 is good for most industries.
Conversion Rate: The ultimate measure. Track by targeting method in Reddit's conversion reporting.
ROAS (Return on Ad Spend): Revenue generated per dollar spent. Retargeting should deliver 3-8x, cold traffic 1.5-3x.

Reddit's Ads Manager provides detailed performance breakdowns by targeting method, community, interest category, and keyword—use this data to double down on winners.

Common Targeting Mistakes to Avoid

Mistake 1: Targeting too broadly. Selecting 20+ interests or 50+ subreddits dilutes your message and prevents optimization learning. Start narrow, expand gradually.

Mistake 2: Ignoring audience size warnings. Reddit shows "too small" or "too large" warnings in campaign setup. "Too small" means you'll struggle to spend budget; "too large" means you're not focused enough.

Mistake 3: Not using negative targeting. Exclude irrelevant subreddits, interests, or keywords to prevent wasted spend. If you sell B2B software, exclude student-focused communities.

Mistake 4: Treating Reddit like Facebook. Reddit users hate obvious ads and respond poorly to hard selling. Your targeting might be perfect, but if your creative feels like an ad, you'll get downvoted and lose relevance score.

Mistake 5: Not refreshing audiences. Subreddit quality changes. Interest behaviors evolve. Rebuild custom and lookalike audiences monthly to maintain performance.

The best way to optimize reddit advertising audience performance is to continuously test new targeting combinations while scaling proven winners.

FAQ

How accurate is Reddit ad targeting?

Reddit ad targeting is highly accurate for intent-based campaigns because users self-select into communities around specific interests. Community (subreddit) targeting is the most precise option, followed by keyword targeting. Interest targeting is less precise but offers more scale. According to Reddit's internal data, keyword targeting delivers 29.6% higher CTR than interest targeting alone, indicating better audience-to-message match.

What is the minimum audience size for Reddit ads?

Reddit requires minimum audience sizes of 1,000 users for most targeting methods. Custom audiences (pixel retargeting, customer lists) need at least 1,000 matched users. Subreddit targeting works with any community size, but communities under 10,000 members may not spend budget efficiently. Lookalike audiences require source audiences of 1,000+ users.

Can you target competitors' subreddits with Reddit ads?

Yes, you can target any public subreddit with Reddit ads, including communities focused on competitor products. This is a common strategy for challenger brands. However, Reddit users are highly skeptical of competitor advertising and will downvote obvious competitive ads. Approach competitor subreddit targeting with value-focused creative, not direct comparisons.

How much do Reddit ads cost with different targeting options?

Reddit ad costs vary by targeting precision. Community targeting typically costs $0.50-$3 CPC for niche subreddits, $2-$5 for competitive communities. Interest targeting averages $0.75-$4 CPC. Keyword targeting runs $1-$5 CPC depending on competitiveness. Custom audience retargeting costs $2-$5 CPC but delivers higher conversion rates. These are significantly lower than LinkedIn ($30+ CPC) or Google Display ($5-$15 CPC).

Should I use automated targeting or manual targeting on Reddit?

Use manual targeting initially to learn which communities, interests, and keywords drive results for your specific offer. Once you have performance data (ideally 50+ conversions), switch to automated targeting to scale. Reddit's automated targeting uses machine learning to optimize audience selection and delivers 11% more conversions at 10% lower CPA according to Reddit for Business, but it needs conversion data to optimize effectively.

How do I find the best subreddits to target for my product?

Start by searching Reddit for topics related to your product, then analyze which subreddits appear in results. Use the Ads Manager's subreddit suggestion tool (under Community targeting) to discover related communities. Look for subreddits with 10,000+ members, active daily posts, and on-topic discussions. Check our guide on how to target ads on reddit for step-by-step subreddit research strategies. You can also browse reddit ads examples to see which communities successful brands target.
