A shopper-first methodology built around evidence.
These principles guide Werveo's development and will be refined through live API benchmarking rather than assumptions about what data providers can supply.
Shopper value first
The winning offer should be selected on customer value and evidence. Monetization belongs downstream of the ranking decision.
Lowest price is not automatically best
Shipping, unavoidable fees, verified promotions, product condition, delivery, seller quality, returns, warranty, availability and membership restrictions can all matter.
Missing is not zero
Unknown shipping does not mean free shipping. Missing stock information does not mean in stock. A promotion that has not been checked is different from a promotion that was checked and not found.
Exact product identity matters
Different storage sizes, colors, generations, regions or bundles should not compete simply because their titles are similar. Werveo is being designed to preserve product-match confidence separately from offer-data confidence.
Evidence needs provenance
Important fields should retain their source, observation time and information state so conflicting inputs can be reconciled and stale data can be identified.
Historical context should degrade gracefully
Historical price evidence can strengthen a decision, but it is not mandatory. Werveo's final historical thresholds will be calibrated only after real provider data is benchmarked across categories and volatility levels.
Be precise about coverage
Werveo should say “best price found” and disclose the sources or retailers it checked rather than imply that every retailer on the internet was searched.
Explain the result
The final output should state why a winner wins. A customer should not have to trust an unexplained numerical score.
