Bidding Wars: When to Compete on Price and When to Walk Away
In a bidding war, the "winner" often just pays the most for traffic that used to cost less. Here's how to compete strategically.
Understanding Bidding Wars
A bidding war occurs when competitors continuously raise bids to win the same auctions. CPCs escalate, margins compress, and often nobody wins except Google. The first step is recognising when you're in one.
Signs of a bidding war: CPCs rising faster than seasonality explains, impression share declining despite budget increases, and competitors consistently appearing in top positions.
The Game Theory
Bidding wars are prisoner's dilemmas. Everyone would be better off with lower bids, but no one wants to reduce first and cede volume. Breaking the cycle requires strategic thinking beyond "bid higher."
When to Fight
Compete in a bidding war when you have structural advantages:
- Higher margins: You can afford CPCs that competitors can't sustain
- Better LTV: Higher customer lifetime value justifies higher acquisition costs
- Superior conversion: Your conversion rate means lower cost per acquisition at same CPC
- Strategic necessity: The traffic is essential and alternatives don't exist
Without at least one of these advantages, competing directly is likely to destroy value.
When to Retreat
Walk away from bidding wars when:
- Margins are equal: No competitor has an advantage; everyone just loses
- CPCs exceed breakeven: You're paying more than the traffic is worth
- Better opportunities exist: Other campaigns or channels offer better returns
- Competitor has deeper pockets: You'll run out of budget before they do
The Ego Trap
Don't compete because "we can't let them win." That's ego, not strategy. The goal is profit, not impression share. Letting competitors overpay for traffic is often the winning move.
Alternative Strategies
Ways to compete without matching bids:
- Long-tail focus: Compete on specific queries where competitors aren't bidding aggressively.
- Time-of-day shifting: Compete during hours when competitors are budget-constrained.
- Audience layering: Focus on audiences with higher conversion rates where you can afford higher CPCs.
- Quality score investment: Higher quality scores mean lower CPCs for the same position.
- Channel diversification: Build traffic from sources competitors aren't contesting.
Defensive Positioning
Protect yourself from being drawn into wars:
- Set POAS floors: Never bid above a level that destroys margin
- Diversify traffic sources: Don't depend on contested auctions
- Build brand: Direct and organic traffic isn't contested in auctions
- Develop unique advantages: Products or services competitors can't match
The Long Game
Competitors who win bidding wars often lose the business war. They deplete cash, damage margins, and train algorithms on unprofitable traffic. Patience is often the best competitive strategy.
Next Steps
Review your highest-CPC campaigns. Are you in a bidding war? If so, do you have the structural advantages to win it profitably?
