When to Ignore Competitors
Competitor spend is an external pressure, not an internal constraint. We optimise for your bank balance, not their ego. Sometimes the winning move is to let them win the auction while you keep the margin.
The "Envy" Approach
Dangerous: Match Impression Share at Any Cost
Strategy: Match competitor impression share
CPC Impact: +45% (uncapped)
Result: Negative contribution
"We're #1 on the page, but losing £5 per order."
The Commercial Approach
Profitable: Protect Payback & Cash
If a competitor wants to buy customers at a 180-day payback when your limit is 60, let them. They are degrading their own liquidity.
You keep the cash. They keep the impression share. Time reveals who made the better choice.
When to Fold
There are specific situations where competing is mathematically wrong:
Low Incrementality
Do not fight for demand you already own organically. If you would get the traffic anyway, paying for it destroys margin without adding revenue.
Price Wars Without COGS Advantage
Matching price without a cost structure advantage is suicide. If their margin is better than yours, competing on price accelerates your losses.
Stock Risk
Why pay to accelerate a stockout on a hero SKU? Let the competitor win the auction, sell their inventory, and be there when customers come back for their second choice.
Principles of Competitive Discipline
- • Competitor spend ≠ your constraint: Just because they have VC cash to burn does not mean you should follow them over the cliff
- • Never chase CPMs into negative contribution: Winning the auction while losing money is not winning
- • Share of Voice only matters if it is incremental and financed: Otherwise it is vanity
"Voice matters only if it is Incremental and Financed. Everything else is ego spending."
Reading Auction Insights Correctly
Do not chase ego metrics. Track impression share and overlap to diagnose whether you are losing on price, creative, or pure spend:
| Signal | Status | Action |
|---|---|---|
| High Overlap + Low Outranking | Nuisance | Monitor CPCs, do not panic raise bids |
| High Overlap + High Top of Page | Threat | Check price competitiveness & offer |
| Sudden Drop in Your IS | Market Shift | Verify CPA rising. If not, let them burn cash |
Diagnose, don't just bid: If you lose impression share but price competitiveness is high, it is a budget/bid issue. If you lose impression share and price competitiveness is low, it is an offer/market issue. Ads cannot fix a bad price.
Client Talking Points
When clients push to match competitor spend:
"We are intentionally opting out of this auction spike. We optimise for contribution and payback, not envy metrics. Let them overpay for these clicks while we protect your cash runway."
"They might be spending more, but we do not know their financing. We will win where we are financed and incremental. Instead of blind matching, here are specific impression share gaps on high-intent terms worth buying right now."
