How we choose what to publish
By Spektrum Glasses Editorial Team · Published 2026-07-18 · Updated 2026-07-20 · Facts re-checked 2026-07-20 How this page is written and checked: our editorial method · how we verify claims This knowledge base is generated by an automated pipeline with a disclosed selection policy:- Buying guides come from measured demand, not guesses. A guide exists only for a search query that real Amazon shoppers typed, with real measured search volume, drawn from Amazon Brand Analytics search-query data for our own listings. We do not invent topics to chase traffic.
- Brand-navigational queries are excluded. Searches that already name our brand get no guide — guides answer open questions.
- Out-of-scope queries are excluded. We publish nothing about products we do not sell (for example prescription or bifocal eyewear), and nothing targeting competitor brand names.
- Two disclosed exceptions: (1) a small set of curated gift guides for the GLACIAL desk line — gift intent is real buyer demand our search data cannot surface, because Brand Analytics only reports queries where our listings already appear; (2) a small set of curated lens-science pages (measured lens comparison, evening screen guide, claim-verification checklist) built directly on the laboratory data hosted on lab results. Both sets are capped and listed in the navigation — we do not mass-generate pages.
- Product pages mirror the live catalogue. Pages are created and retired automatically as listings go live or are discontinued; product facts are re-pulled from the live Amazon listing nightly and date-stamped.
- Every page passes a claims gate. Wording that states or implies a medical outcome is removed before publish — see how we verify claims.
- Numbers we cannot fetch automatically (for example Amazon star ratings, which have no public API) appear only as owner-verified facts with an as-of date and a link to the public source, and are withheld automatically once the verification is older than 60 days.
