Google App Campaigns vs Meta vs TikTok: Which to Pick (2026)

Apple Search Ads gets covered separately because it's a category of its own (in-store, highest intent). But for indie devs growing paid acquisition beyond ASA, the three big channels are:

• Google App Campaigns (UAC)
• Meta (Facebook / Instagram)
• TikTok

This is the honest comparison.

TL;DR

• Google App Campaigns: best for broad reach + Android-heavy targeting. Hands-off (Google's AI handles most optimization).
• Meta: best targeting precision. Strongest for premium/niche audiences.
• TikTok: cheapest for many categories. Best creative platform for visually-driven products.

Start with one. Add channels as you validate ROAS.

Google App Campaigns

How it works

Google App Campaigns (formerly UAC) is a fully-automated bidding platform. You provide:

• Target CPA or target ROAS.
• Daily budget.
• Up to 5 headlines + 5 descriptions.
• Up to 20 image assets.
• Up to 20 video assets (or YouTube uploads).

Google's AI mixes assets dynamically across Search, Display, YouTube, Discover, and Play Store ads.

Strengths

• Reaches Play Store directly. Heavily favored for Android user acquisition.
• Discovery + YouTube reach for upper-funnel.
• Automation — Google optimizes within your target CPA.
• iOS support also strong via SKAdNetwork.

Weaknesses

• Lower control. You can't see per-creative performance reliably.
• Limited targeting. You can suggest interests, but Google decides.
• Optimization phase lag. New campaigns take 5-15 days to ramp.

CPI (2026 US median)

• Casual games: $3-$8
• Productivity: $4-$8
• Health & Fitness: $5-$12
• Photo & Video: $4-$10
• Finance: $8-$20

Best for

• Android-heavy targeting.
• Teams with limited time for hands-on optimization.
• Apps with broad audience.
• Apps with multiple creative variants ready.

See Google App Campaigns UAC guide 2026 and Google Ads mobile app campaigns guide 2026.

Meta (Facebook / Instagram)

How it works

You build ad sets with:

• Targeting (audience, geo, age, interests, custom audiences).
• Creative (image, video, carousel, dynamic).
• Placement (Facebook feed, Instagram feed, Stories, Reels, etc.).
• Bidding strategy.

Meta's algorithm optimizes within your targeting.

Strengths

• Best targeting precision. Custom audiences (lookalikes), interest targeting, geo targeting.
• Most creative formats. Image, video, carousel, dynamic, collection.
• Multiple placements: Facebook, Instagram, Messenger, Audience Network, Reels.
• Mature attribution + reporting.

Weaknesses

• High CPI in many categories (Meta is the most-bid platform).
• iOS attribution loss post-ATT — still painful for iOS-heavy apps.
• Creative fatigue fast. Need new creative every 2-4 weeks.

CPI (2026 US median)

• Casual games: $5-$12
• Productivity: $5-$10
• Health & Fitness: $6-$15
• Photo & Video: $5-$12
• Finance: $10-$25
• Dating: $10-$30
• Subscription apps (in general): $8-$20

Best for

• Premium apps with high LTV.
• Apps with strong demographic targeting (specific age / interest groups).
• Apps with rich creative library.
• Brands with email lists / custom audience seeds.

TikTok

How it works

You build ad groups with:

• Targeting (interest, behavior, geo, age).
• Creative (vertical video required, native to TikTok format).
• Bidding (CPM, CPC, or oCPM optimized for installs).

TikTok's algorithm pushes performant creative to broader audiences.

Strengths

• Lowest CPI for many consumer categories in 2026.
• Best for short-form video creative.
• Younger audience (18-35).
• Strong organic + paid synergy — UGC-style ads work.

Weaknesses

• Older audiences underrepresented.
• Creative production can be intensive (vertical video, native style).
• Attribution still maturing.
• Brand safety considerations in some categories.

CPI (2026 US median)

• Casual games: $2-$5
• Productivity: $1-$4
• Health & Fitness: $3-$7
• Photo & Video: $2-$5 (excellent fit)
• Finance: $5-$12 (regulated category, slower)
• Dating: $5-$15

Best for

• Consumer apps with younger target audiences.
• Visually-driven products (photo/video, food, fashion).
• Apps that work well with UGC-style creative.
• Cost-conscious indie teams.

The "start with one" approach

Don't run all three at $100/day each. You'll get noisy data on all of them.

Start with one channel at $50-$200/day. Run for 2-3 weeks. Measure ROAS rigorously. Either:

• Scale that channel.
• Pivot to the next channel and repeat.

Once you've validated ROAS on one channel, layering a second is sane.

ROAS expectations by channel

Median D30 ROAS for indie subscription apps in 2026:

• Apple Search Ads: 60-100% (highest intent)
• Google App Campaigns: 40-80%
• Meta: 30-70%
• TikTok: 35-75% (high volatility)

Top quartile is 1.5-2× these numbers. If you're below median, fix the funnel (onboarding, paywall, listing) before scaling.

Creative refresh cadence

TikTok especially: stale creative is the #1 reason TikTok ROAS dies. Plan creative production cadence accordingly.

Attribution differences

All three channels report through their own dashboards + SKAdNetwork for iOS:

• Google: First-party referrer (Android) + SKAN (iOS).
• Meta: First-party (Android via Facebook SDK) + SKAN.
• TikTok: First-party + SKAN.

Cross-channel attribution overlap is real — sum your channel-reported installs and you'll exceed actual installs by 20-50%. Use an MMP for deduplication at scale.

See MMP comparison and attribution explained.

Common mistakes

• Running all three from day 1. Noisy data, poor optimization.
• Same creative across channels. Each platform has format requirements.
• Comparing CPI without accounting for LTV by channel. Lower CPI ≠ better channel.
• No creative refresh schedule. Especially TikTok dies fast on stale creative.
• Skipping iOS SKAN configuration. Wastes performance data.
• Setting wrong target CPA. Calculate max CAC first (see CAC guide).

Run unit economics first

Before scaling any channel, model your funnel in Ad Analytics Calculator. Know your max CPI before bidding. Otherwise you'll burn budget waiting for clarity.
