Reddit Advertising Targeting: All Options Explained

Reddit's targeting options allow you to reach specific audiences based on their interests, communities, behaviors, and demographics. Understanding these options is essential for creating effective campaigns that connect with the right users. This guide explains every targeting method available on Reddit in 2026.

Community (Subreddit) Targeting

Community targeting is Reddit's most powerful and distinctive targeting option. It lets you place ads in specific subreddits where your target audience participates.

How It Works

When you target a subreddit, your ads appear to users who view or engage with that community. Reddit has over 100,000 active communities spanning virtually every interest and topic.

Best Practices

Research before targeting: Spend time in potential target subreddits to understand community culture, language, and what content resonates.

Start specific, then expand: Begin with 5-10 highly relevant subreddits rather than hundreds. Test performance before broadening.

Group similar communities: Create ad groups that combine subreddits with similar audiences for efficient learning.

Use exclusions strategically: Exclude communities where your brand may not fit the culture or conversation.

When to Use

• You know exactly which communities your audience frequents
• Your product/service aligns with specific interest groups
• You want maximum relevance and engagement
• You have creative that matches community culture

Interest Targeting

Interest targeting reaches users based on their broader interest patterns across Reddit, not just specific subreddits.

Available Interest Categories

Reddit offers interest targeting across major categories:

How It Works

Reddit identifies user interests based on:

• Subreddits they subscribe to and visit
• Content they engage with (upvotes, comments, saves)
• Time spent in different topic areas
• Search behavior within Reddit

Best Practices

Combine with other targeting: Layer interests with location or device targeting for precision.

Use for broader reach: Interest targeting casts a wider net than subreddit targeting.

Test interest groupings: Different interest combinations may reach distinct audience segment segments.

Keyword Targeting

Keyword targeting shows your ads when users search for specific terms on Reddit or engage with content containing those keywords.

Types of Keyword Targeting

Search Keywords: Target users actively searching for specific terms within Reddit.

Contextual Keywords: Target based on content and conversations users engage with.

Building Keyword Lists

Effective keyword lists include:

• Product terms: Names of products/services you offer
• Problem terms: Issues your product solves
• Competitor terms: Alternative solutions users might consider
• Industry terms: Broader category language

Match Types

Reddit uses broad matching by default, meaning your ads may appear for variations and related terms. Be specific with keywords to maintain relevance.

Best Practices

• Start with 20-50 relevant keywords per ad group
• Monitor search terms report to identify winners and add negatives
• Separate high-intent keywords into their own ad groups
• Update keywords based on actual search query performance

Location Targeting

Reach users based on their geographic location.

Available Options

How Location Is Determined

Reddit identifies user location through:

• IP address analysis
• Device location signals (when enabled)
• Account settings

Use Cases

• Local businesses: Target city or metro areas
• National campaigns: Target specific countries
• Regional offers: Target states/provinces with different promotions
• Geo-exclusions: Exclude regions where you don't operate

Device Targeting

Reach users on specific devices and platforms.

Device Options

Platform

• Desktop (web browsers)
• Mobile Web (mobile browsers)
• iOS App (Reddit mobile app on iPhone/iPad)
• Android App (Reddit mobile app on Android)

Platform Considerations

Best Practices

• Analyze performance by device and adjust bids accordingly
• Consider device when choosing creative (video works well on mobile)
• Separate campaigns by device for granular optimization
• Desktop often converts better for B2B and high-consideration purchases

If you're running reddit ads for b2b campaigns, device targeting becomes especially important for optimizing conversion paths.

Custom Audiences

Create audiences based on your own customer data and website visitor behavior.

Website Custom Audiences (Pixel-Based)

Using the Reddit Pixel, create audiences from:

• All website visitors: Anyone who visited your site
• Page viewers: Visitors to specific pages
• Event completers: Users who took specific actions
• Purchase audiences: Past customers

Lookback Windows

Customize how far back to include visitors:

• 7 days (recent, high-intent)
• 30 days (broader, still relevant)
• 60 days (wider reach)
• 180 days (maximum reach)

Customer List Uploads

Upload email lists to create audiences:

• CRM customer lists
• Newsletter subscribers
• Past purchasers
• High-value customer segments

Reddit matches your data against its user base while maintaining privacy through hashing.

Lookalike Audiences

Create audiences that resemble your best customers:

1. Start with a seed audience (pixel or upload)
2. Reddit identifies users with similar characteristics
3. Target these lookalikes to find new customers

Lookalike audiences work best when your seed audience is substantial (1,000+ users) and clearly defined. Properly tracking these conversions requires robust reddit ads conversion tracking implementation.

Audience Expansion

Reddit offers audience expansion options to increase reach beyond your core targeting.

How It Works

When enabled, Reddit may show ads to users beyond your specified targeting who are likely to respond positively based on performance data.

When to Use

• You have strict conversion goals and sufficient data
• MAX Campaigns (automated expansion built in)
• Learning phase for new campaigns

When to Avoid

• You need precise audience control
• Brand safety is a top concern
• Testing specific targeting hypotheses

AI-Powered Targeting (2026)

Reddit's MAX Campaigns introduce AI-driven targeting that automates audience optimization.

How MAX Targeting Works

MAX Campaigns analyze Reddit Community Intelligence—over 23 billion posts and comments—to:

• Identify high-converting audience segments automatically
• Shift budget toward best-performing targeting
• Discover new audiences you might have missed
• Optimize in real-time based on conversion signals

Top Audience Personas

MAX Campaigns reveal which audience segments drive results through Top Audience Personas—showing you the communities and interest patterns of your converting users.

When to Use MAX

• Conversion-focused objectives
• Sufficient budget ($50+/day) for learning
• Willingness to let AI optimize
• Desire for broader reach with efficiency

Combining Targeting Options

Layer multiple targeting options for precision:

Effective Combinations

Targeting Hierarchy

When multiple options are combined, Reddit uses AND logic—users must match all criteria to see your ad. This narrows your audience but increases relevance.

Frequently Asked Questions

What'S the Minimum Audience Size for Reddit Targeting?

Reddit recommends targeting audiences of at least 50,000-100,000 users for effective delivery and optimization. Smaller audiences may result in limited delivery or higher costs. If your targeting is too narrow, broaden by adding subreddits, interests, or expanding location parameters.

Can I Target Specific Users or Usernames on Reddit?

No, Reddit doesn't allow targeting individual users by username. The platform protects user privacy by only allowing aggregate targeting based on interests, communities, and behaviors. Custom audiences based on email lists are matched anonymously.

Which Targeting Option Performs Best?

Performance varies by advertiser and objective. Generally, subreddit targeting delivers highest relevance and engagement for brands that understand their communities. For scale and efficiency, interest targeting or MAX Campaigns often perform well. Test multiple approaches and let data guide your strategy. If you need expert guidance, working with a reddit advertising agency can help optimize your targeting strategy.

How Often Should I Update My Targeting?

Review targeting performance weekly during active campaigns. Make adjustments when you have sufficient data (typically after 7-14 days or several thousand impressions per targeting option). Avoid constant changes that reset learning; instead, make strategic adjustments based on clear performance patterns.
