Use this public experiment record to separate a hypothesis from an outcome and to preserve cohorts, guardrails, confounders and the exact production change.
If [change], then [metric] will [direction]
for [cohort] within [window], because [mechanism].
Usable preview
For eligible guides with impressions but low CTR, revise only titles that mismatch observed query intent. Guardrails: stable indexability and no loss of qualified conversions. Review after a predeclared comparable window.
Limitation: SEO experiments rarely isolate every external search change. Use cohorts and transparent uncertainty, not false certainty.
