1. Define one decision
Every page must answer one identifiable task: form a shortlist, verify a specific product, find an alternative for a known reason, or calculate value when adequate data exists.
2. Lock the exact variant
We record brand, model, ASIN where applicable, capacity and selected variation. Reviews or attributes are not silently moved between child variants.
3. Rank and label sources
A model-matched manufacturer page normally outranks an ambiguous marketplace attribute for technical specifications. Marketplace data remains useful for exact listing identity, captured price and availability. Conflicts remain visible.
4. Show calculations
Derived values identify inputs, formula and unit. Missing inputs produce an unknown or a reduced conclusion, not an estimated fact presented as measured.
5. Challenge the conclusion
We vary sensitive assumptions, look for disqualifying constraints and state who should not follow the recommendation. Revenue does not enter ranking or conclusions.
AI and automation
Automation may assist with extraction, normalization, calculations, consistency checks and drafting. It does not make unsupported ownership or testing claims. Material factual conclusions must remain traceable to cited evidence or visible calculations.
Updates
Identity and specification changes trigger review. Prices are snapshots unless explicitly supplied as live data. Updating a date without substantive review is not permitted.
