We rank the completeness and decision-usefulness of evidence, not brands that pay more. Every product is a canonical entity, every offer is separate, every fact has provenance, and missing or conflicting data stays visible.
What makes a product research-ready?
A product becomes indexable only when enough first-party facts exist to answer a distinct buyer question. Core fields depend on category: electrical load, dimensions, capacity, heater or cooling system, installation, warranty, and current source identity. A brand name and marketing paragraph are not enough.
- Official manufacturer or authoritative support documentation for specifications
- Independent research for safety and physiology context
- Community discussions only for discovering recurring questions, not as proof
- A dated last-reviewed field and confidence label on each fact
How are facts normalized?
We preserve the published value, attach a source URL and verification date, and normalize concepts into comparable fields. We do not silently convert a controller setting into measured body temperature, a horsepower label into complete-system performance, or nominal capacity into comfortable user fit.
- Verified: directly supported by the cited source
- Manufacturer claim: published but performance-dependent
- Conflicting: current sources disagree
- Not published: no defensible value was found
How are rankings and comparisons decided?
Launch pages organize products by fit and constraint rather than assigning a universal winner. Comparison tables emphasize electrical work, space, filled weight, heat or cooling architecture, maintenance, warranty, and repairability. Price never substitutes for a missing safety or installation fact.
- No pay-to-rank placements
- No cross-category false equivalence
- No clinical scoring from manufacturer wellness claims
- No automatic positive score for an affiliate relationship
How are pages updated?
Stable product specifications and volatile offer data have separate lifecycles. Prices, availability, destinations, and affiliate eligibility can expire independently of a product page. A connector must pass validation, product matching, territory, and link-health checks before it can change an offer.
- Daily connector endpoint is ready for approved feeds
- Stale or broken offers are removed from commercial display
- Core product changes require source-level review
- Thin records remain noindex until complete
What does SweatFreeze not claim?
SweatFreeze does not clinically test the catalog, provide medical advice, or claim that saunas and cold immersion treat disease. Product performance varies with installation, ambient conditions, user behavior, and maintenance.
