Less noise. More signal.
Comparison methodology
Verified comparisons are one of three core Green Star trust outputs alongside verified customer reviews and evidence-backed business profiles. Comparison research is editorial and independent — it is not the same as customer review content, and appearing in research is not an endorsement or commercial participation.
- Identify businesses for a category (admin-approved).
- Fetch public sources with safety controls.
- Store structured evidence with URLs, confidence, and history.
- Generate comparisons only from stored evidence.
- Run an independent verification pass (GREEN / AMBER / RED).
- Publish only approved pages. AMBER requires human review. RED cannot publish.
Absence of evidence is not evidence of absence. If we cannot identify a feature in sources reviewed, we say so — we do not claim the product lacks it. Research has verification dates where recorded; facts come from identifiable sources.
Customer reviews are moderated and verified under a separate process. Editorial research does not invent ratings or review volume.
Facts, ratings, and analysis
Every published comparison keeps three layers separate, visually and in copy:
- Verified facts — objective information such as UK list prices and published features. Each fact has an identifiable primary source URL and an ISO date checked. We prefer vendor official pages. Missing evidence is not treated as proof that a feature does not exist.
- Customer experience — structured Green Star ratings from Green Star customers only. If there are not enough real responses for a metric, we show “Not enough Green Star ratings yet” and a way to rate it. We never invent numeric ratings and never substitute editorial stars.
- Green Star analysis — a short, labelled opinion to help someone decide. It is not a verified fact and not a rating. We do not call a product a winner unless that sentence is clearly analysis.
