Best TikTok Targeting Options for Apps (2025)

Broad targeting on TikTok delivers 15% lower cost per acquisition and 20% higher conversion rates compared to narrow audiences.

This contradicts conventional wisdom from Facebook and Google, where precise targeting often wins. But TikTok's algorithm works differently—it's exceptionally good at finding converters within large audiences.

Here's which targeting options actually drive efficient app installs and when to use each.

The Broad Targeting Advantage

TikTok defines "fairly broad" audiences as reaching 80% or more of users in a given country.

Data from TikTok's own analysis shows these broad campaigns consistently outperform narrow ones.

Why broad targeting works on TikTok:

TikTok's algorithm optimizes delivery based on user behavior, not just demographic or interest signals. When you give it a large audience, it has more data to identify patterns in who converts.

Narrow targeting (specific age ranges, niche interests, hyper-local geos) restricts the algorithm's ability to find converters outside your assumptions.

When to use broad targeting:

• New campaigns with no historical data
• Apps with broad appeal (productivity, social, entertainment)
• When you want to discover unexpected audience segments
• Budgets over $50/day (enough to give the algorithm learning data)

How to implement:

• Target an entire country or major region
• Set age range to 18-55+ (unless your app has age restrictions)
• Enable Smart Targeting
• Let the algorithm identify converters

Smart Targeting: Let TikTok Expand Your Audience

Smart Targeting is a feature that allows TikTok to deliver ads beyond your specified targeting if it detects better performance.

How it works:

You set baseline targeting (interests, demographics, etc.). If TikTok's algorithm identifies users outside those parameters who are likely to convert, it expands delivery to include them.

Example:

You target "fitness enthusiasts" for a workout app. Smart Targeting notices that users interested in "meal planning" also convert well, so it expands to include that segment automatically.

When to enable Smart Targeting:

Almost always. The only exception is if you have hard constraints (like age restrictions for an app targeting minors or specific compliance requirements).

Performance impact:

Campaigns with Smart Targeting enabled often see 10-20% lower CPIs as the algorithm finds high-intent users you wouldn't have manually targeted.

Interest Targeting: When Specificity Matters

Interest targeting delivers ads to users based on the content they engage with on TikTok.

Available interest categories:

• Business & Industry
• Education
• Family & Parenting
• Fashion & Beauty
• Fitness & Wellness
• Food & Beverage
• Gaming
• Hobbies & Activities
• Home & Garden
• News & Entertainment
• Pets
• Sports
• Technology
• Travel

When interest targeting works:

• Apps with clear audience affinities (meditation app targets "Fitness & Wellness")
• Niche apps serving specific communities (recipe app targets "Food & Beverage")
• When you want to test whether specific segments outperform broad audiences

When to avoid it:

• Apps with universal appeal where interests don't predict usage
• Low budgets that can't support multiple interest-based ad groups
• When you're still in early testing and don't know your ideal user

Best practice:

Run broad targeting and interest targeting simultaneously in separate ad groups. Compare CPIs after 7-14 days to see if the added specificity improves or hurts performance.

Behavior Targeting: Finding App Downloaders

Behavior Targeting focuses on in-app actions users take on TikTok, such as video interactions or creator follows.

Most relevant behaviors for app campaigns:

• App install behavior: Users who frequently download and engage with apps
• Video interaction patterns: Users who watch videos to completion, engage heavily
• Shopping behavior: Users who interact with e-commerce content (for transactional apps)

Why this works:

Behavior signals predict future actions better than demographics. Someone who downloads apps frequently is more likely to install yours, regardless of their age or interests.

When to use behavior targeting:

• Apps competing in crowded categories (finding users willing to try new apps)
• After you've validated broad targeting (layering behavior for refinement)
• Retargeting campaigns where you want highly engaged users

Lookalike Audiences: Modeling Your Best Users

Lookalike audiences find new users similar to your existing converters.

How they work:

You provide a seed audience (installers, purchasers, engaged users). TikTok analyzes their characteristics and behaviors, then finds similar users.

Lookalike audience sizes:

• 1% lookalike: Most similar to your seed audience (highest quality, smallest scale)
• 3-5% lookalike: Moderately similar (balance of quality and scale)
• 5-10% lookalike: Broader match (maximum scale, lower similarity)

When to create lookalikes:

Once you have at least 100 converters in your seed audience. Smaller seeds produce unreliable lookalikes.

What to seed with:

Don't just use all installers. Seed with your highest-value users:

• Users who completed registration (not just installed)
• Users who made a purchase
• Users with 7-day retention
• Users who completed key in-app events

High-quality seeds produce high-quality lookalikes.

Testing lookalike sizes:

Run 1%, 3-5%, and broad targeting in parallel. Often, 1% lookalikes drive the best CPIs, while broad targeting drives the most volume. Use both.

Custom Audiences: Retargeting Engaged Users

Custom audiences let you retarget users who interacted with your brand but didn't convert.

Custom audience types for apps:

1. TikTok engagement audiences

Users who:

• Watched your video ads
• Clicked on your ads
• Liked, commented, or shared your ads
• Visited your profile

2. App activity audiences

Users who:

• Visited your app store page (via TikTok tracking)
• Opened your app
• Completed specific in-app events

3. Customer file uploads

Email lists or user IDs from your CRM to retarget existing users or create exclusions.

Best retargeting strategies:

Retarget ad clickers who didn't install:

These users showed intent but didn't convert. A reminder ad often pushes them over the edge.

Retarget app store page visitors:

They made it to the store but didn't install. Address objections (price, skepticism) in retargeting creative.

Exclude existing users:

Upload your user database and exclude them from prospecting campaigns to avoid wasting budget on people who already installed.

Demographic Targeting: When It Matters

Age, gender, and location targeting are table stakes, but they rarely drive performance improvements on their own.

When demographics matter:

• Age restrictions (apps for minors or adults only)
• Gender-specific apps (period tracking, pregnancy apps)
• Regional apps (food delivery, local services)

When demographics don't matter:

• Apps with universal appeal (productivity, finance, education)
• When you're testing and don't know your ideal user

Best practice:

Start broad on demographics unless you have a clear reason to narrow. Let conversion data tell you who your users are rather than assuming.

Geographic Targeting: Countries vs. Regions

You can target by country, state/province, city, or even postal code.

Optimal geographic approach for apps:

• Tier 1 markets (US, UK, Canada, Australia): Start here if you want high LTV users and can afford $3-5 CPIs
• Tier 2 markets (Western Europe): Good balance of volume and LTV
• Tier 3 markets (Southeast Asia, Latin America): Lower CPIs ($1-2) but also lower LTV

Multi-country vs. single-country campaigns:

Test single countries first to understand performance by market. Once you have winners, you can combine similar-performing geos into regional campaigns.

Don't over-narrow:

Targeting a single city or postal code limits scale and often increases CPIs due to auction competition. Stick to country or state-level targeting unless you have a local service app.

Device and OS Targeting

You can target by:

• Operating system (iOS vs. Android)
• Device type (phone vs. tablet)
• Connection type (WiFi vs. cellular)

When to separate iOS and Android:

If your app economics differ significantly by platform (iOS users have higher LTV), run separate campaigns for each. Otherwise, target both.

WiFi vs. cellular:

Some advertisers restrict to WiFi-only to encourage immediate installs (users more likely to download large apps on WiFi). Test this if your app is over 100MB.

Targeting Strategy by Campaign Stage

Your targeting should evolve as campaigns mature.

Stage 1: Launch (Week 1-2)

• Broad targeting with Smart Targeting enabled
• Single country or region
• Minimal demographic restrictions
• Goal: Find any conversion signal

Stage 2: Testing (Week 3-6)

• Add interest-based ad groups
• Test 1% lookalikes seeded with installers
• Layer behavior targeting
• Goal: Identify which targeting approaches drive lowest CPIs

Stage 3: Scaling (Week 7+)

• Double down on winning targeting methods
• Expand to 3-5% lookalikes for volume
• Add retargeting for engaged non-installers
• Goal: Scale efficient channels while maintaining CPIs

Targeting Checklist

When setting up TikTok app campaign targeting:

• Have you started with broad targeting (80%+ of country) and Smart Targeting enabled?
• Are you testing interest and behavior targeting in separate ad groups?
• Have you created lookalike audiences if you have 100+ converters?
• Are you retargeting engaged users who didn't install?
• Have you avoided over-narrowing demographics unless necessary?

FAQs

Should I use broad or narrow targeting for TikTok app ads?

Broad targeting outperforms narrow targeting on TikTok. Campaigns reaching 80%+ of users in a country achieve 15% lower CPAs and 20% higher conversion rates compared to narrow audiences. TikTok's algorithm is effective at finding converters within broad parameters.

What is Smart Targeting on TikTok?

Smart Targeting allows TikTok to deliver ads beyond your specified targeting settings if it improves performance. When enabled, TikTok's algorithm can expand to untargeted audiences that show strong conversion potential based on behavior patterns.

When should I use lookalike audiences for app campaigns?

Create lookalike audiences once you have at least 100 converters (installs or in-app events). Start with 1% lookalikes for quality, then test 3-5% for scale. Lookalikes work best when seeded with high-value users, not just any installers.

Should I target iOS and Android separately?

Only if your unit economics differ significantly by platform. If iOS users have 2x the LTV of Android users, separate campaigns let you bid more aggressively for iOS. Otherwise, targeting both simplifies management.

How often should I refresh my targeting strategy?

Review targeting performance every 14 days. If certain ad groups consistently underperform, pause them and reallocate budget to winners. Don't change targeting more frequently—give the algorithm time to optimize.
