The Platform Problem
Core Premise: LinkedIn, Meta, and Google are designed to extract maximum spend from advertisers. Their algorithms, defaults, and recommendations serve their revenue, not your results.
The Adversarial Relationship
Every major advertising platform runs an auction. The platform's goal is to maximize revenue per impression. Your goal is to minimize cost per customer.
These goals are fundamentally opposed.
The Auction Tax
The Auction Tax is the premium you pay when your demand generation fundamentals are weak.
The Auction Tax can represent 40-70% of demand spend. Companies with weak fundamentals pay double for the same audience access.
| Advertiser | Relevance | Engagement | Effective CPM |
|---|---|---|---|
| Strong Fundamentals | 8/10 | 2.5% | $30 |
| Weak Fundamentals | 4/10 | 0.8% | $75 |
Same platform. Same audience. 12.5x cost difference.
Platform-Specific Extraction Tactics
Audience Expansion (Default On): Expands beyond your targeting. Disable on every campaign.
LinkedIn Audience Network: Shows your B2B ads on mobile games. Disable unless proven effective.
Engagement-Optimized Bidding: Optimizes for cheapest result, not best result.
Meta
Advantage+ Audience: Expands to find cheap conversions that often mean consumers, not B2B buyers.
Advantage+ Placements: Distributes to cheap, low-quality inventory.
Broad Match Defaults: "B2B marketing software" triggers ads for "marketing degree programs."
Performance Max: Black box that burns budget with no visibility.
The Platform Defense Playbook
Defense 1: Default Distrust - Audit every default setting. Disable expansions.
Defense 2: Manual Control - Manual bidding, specified audiences, selected placements.
Defense 3: Independent Measurement - Do not trust platform-reported conversions.
Defense 4: Creative Velocity - Launch new creative before decay. Test continuously.
Defense 5: Portfolio Diversification - No single platform should exceed 60% of spend.
