Reinforcement Learning for Apple Ads

Apple Ads auctions change constantly. Competition, user behavior, and seasonality shift daily. Reinforcement learning continuously adapts to these changes, learning from every interaction.

What is Reinforcement Learning?

A machine learning paradigm where an agent learns optimal behavior by trial and error, maximizing cumulative rewards over time.

Bidding Strategy Learning

Pre-trained through millions of simulated auctions, the model learns optimal bidding strategies before deployment.

When activated on your campaigns, it's already optimized and ready to perform, fine-tuning only to your specific goals.

Reward Over Time

Reward represents performance relative to your goals (CPA, ROAS).

During pre-training in simulations, early exploration yields low rewards. As the model discovers better strategies, performance improves steadily, ready for deployment.

Why Traditional ML Falls Short for Apple Ads

Apple Ads auctions are dynamic systems where static models quickly become obsolete.

The Challenge

  • Dynamic Competition: Bids and prices shift hourly
  • Seasonality: User behavior changes constantly
  • Budget Constraints: Keywords compete for limited daily spend

Exploration vs Exploitation

Traditional models only scale what works (exploitation). RL balances scaling proven strategies with testing new opportunities (exploration).

Exploitation

Scale high-performing keywords

Exploration

Test new keywords and bid levels

How Our RL System Works

Purpose-built for Apple Ads optimization, trained on campaign-specific data.

What It Observes

  • • Performance metrics
  • • Budget status
  • • Competition signals

What It Controls

  • • Bid adjustments
  • • Keyword priority
  • • Budget allocation

What It Optimizes

  • • CPA minimization
  • • ROAS maximization
  • • Incremental growth

Two-Phase Training

Offline simulation for training, online fine-tuning to adapt to your specific goals.

1

Offline Pre-Training

Trained on millions of simulated auctions. Learns general bidding strategies without risking budgets.

2

Online Fine-Tuning

Adapts to your real campaign data. Learns app-specific patterns and optimizes for your goals.

Proven Results

Every flagship model is validated through backtesting and A/B testing before deployment.

Backtesting

Historical campaign replay validates performance improvements

A/B Testing

Control vs RL comparison provides clear metrics

Incrementality

Ensures conversions are truly incremental, not cannibalized

Real Case Studies

Measurable results across multiple industries

What the RL System Does

Autonomous optimization, every day.

1

Observes Performance

Pulls latest campaign data daily

2

Analyzes Patterns

Identifies winners, losers, and shifts in conversion rates

3

Adjusts Bids

Calculates optimal bid for each keyword

4

Explores Opportunities

Tests new keywords and bid levels

5

Manages Budget

Ensures optimal pacing and allocation

6

Learns & Adapts

Updates strategy based on outcomes

What Makes It Different

Apple Ads-Specific

Purpose-built for ASA auction dynamics, not adapted from other platforms.

Millions of Training Scenarios

Pre-trained on far more auction environments than any single client generates.

Incrementality-Aware

Optimizes for real growth, not organic cannibalization.

Never Stops Learning

Continuous updates as market conditions evolve and data accumulates.

Private & Isolated

Each client gets a dedicated model. Your data stays yours.
