The Challenge

A new pet app had built something pet owners genuinely loved.

The problem?

Not enough of them knew it existed.

Previous paid campaigns had generated underwhelming results at CPIs consistently above $3.00.

Creatives were not stopping the scroll. There was no structured testing process to identify what worked.

And without a clear framework for scaling, every dollar spent felt like a gamble.

The goal was clear: build a Meta Ads management system that could drive real install volume at a cost that made growth sustainable.

Three objectives drove everything we did:

Generate high-volume app installs from genuine pet owners
Bring Cost Per Install down to a commercially viable level
Build a repeatable, scalable paid growth system for the long term

Our Solution

We rebuilt the campaign from scratch with a focus on two things: creative that converts and a campaign structure built for scale. No guesswork. No wasted spend.

1. Creative Testing Framework

Creative is the most powerful lever in any Meta campaign, and it was exactly where the previous efforts had fallen flat. We launched a structured creative testing matrix across multiple ad formats to find what actually resonated with pet owners:

Creative Format Performance Table

Creative Format	Performance	Role	Priority
Video (UGC-style)	Highest CTR; drove majority of installs	Primary	High
Static carousel	Strong for feature showcasing	Secondary	Medium
Story / Reel format	Low CPI; used for retargeting	Supporting	Low

Every creative ran in its own isolated ad set for clean, reliable data. Winners were scaled fast.

Underperformers were cut within 48 to 72 hours. This tight iteration cycle compressed the learning phase and drove CPI down quickly.

2. Campaign Structure and Bidding Strategy

We structured campaigns using Meta's App Install objective with Advantage+ placements to maximize delivery efficiency across Facebook, Instagram, Stories, and Reels.

A target cost cap bidding approach kept CPI locked in throughout scale-up, preventing runaway spend as budgets increased.

Campaign 1: Broad prospecting with active creative testing
Campaign 2: Lookalike scaling from 1 to 3% LAL based on top users
Campaign 3: Retargeting warm audiences who engaged but had not yet installed

3. App Store Listing Optimization

Paid ads get users to the door. The App Store listing has to close the deal. We audited the apps's listing and identified conversion friction at the point of install.

Updates toscreenshot sequencing, preview video content, and keyword-optimized descriptions ensured the messaging matched what users had just seen in the ad, reducing drop-off at the final step.

Thirty days. One channel. Over 4,000 installs at a CPI that beat industry benchmarks by nearly half.

Key Performance Metrics

Campaign Metrics Table

Metric	Result
Total App Installs	4,000+
Cost Per Install (CPI)	$1.10
Campaign Duration	30 Days
CPI vs. Industry Benchmark ($2.00 to $4.00)	45 to 72% Below Average
Primary Channel	Meta (Facebook and Instagram)

Performance Highlights

CPI of $1.10, well below the mobile app industry average of $2.00 to $4.00 for iOS and Android
4,000+ installs generated in a single month, creating a strong foundation for continued scale
UGC-style video creative drove over 60% of total installs across the campaign
Retargeting campaigns converted warm audiences at a CPI 22% lower than cold prospecting
App Store listing improvements reduced install drop-off and increased conversion at the final step

The results exceeded everything we expected. We had been struggling to get installs at a reasonable cost for months, and within 30 days we had over 4,000 new users on the app at $1.10 each. The team understood our audience and built creative that actually resonated with pet owners.

Mobile Security App

Strataigize reignited growth for a stalled security/VPN app by fixing cross-platform data discrepancies and reorienting Google Ads around clean purchase signals rather than unreliable value metrics. They added diagnostic-only funnel events, refined geos toward high-intent, revenue-producing markets, and reset messaging to filter out low-quality traffic before install. This data-first, intent-led strategy traded empty volume for efficiency, unlocked the first paid conversions after stagnation, and was reinforced by ASO gains. Key takeaway: reliable, aligned data is the foundation for scalable, revenue-driven acquisition.
