Direct answer

Search competition is a repeated allocation problem: work invested in one query, page or format has an opportunity cost elsewhere, while competitors can respond and outcomes remain uncertain.

Game-theory research offers useful intuition about incentives, change costs and instability, but its controlled models do not reveal Google’s ranking function, prove a Nash equilibrium or guarantee an outcome.

Practical steps

  1. Define a portfolio of user tasks and the evidence each existing page already serves.
  2. Estimate value, relevance, effort, change cost, overlap and volatility as explicit assumptions—not external facts.
  3. Compare balanced, value-led and stability-led allocations while enforcing a non-negotiable user-value and editorial-quality gate.
  4. Observe real outcomes over comparable periods, record competitor responses and revise without chasing every ranking movement.

Example

A team with 100 effort units may choose 45 for a high-value gap, 35 for preserving a strong but volatile page and 20 for discovery work. The allocation is a scenario, not a prediction; if a proposed change weakens the page, its allocation becomes zero.

Common mistakes

  • Copying a winning competitor’s wording or structure as if it were a stable best response.
  • Treating one query in isolation while the same page and team serve several tasks.
  • Calling an allocation formula a Google factor, Nash equilibrium or ranking forecast.

Limitations

  • Competitor intent, ranking mechanisms and future actions are only partly observable.
  • The planning weights are user-owned assumptions and require calibration against first-party evidence.
