# Evidence-Based Reviews

Produce product reviews and buying guides whose claims match their evidence. The method is evidence synthesis with a disclosed basis, and one rule anchors everything: never claim hands-on time that did not happen.

Most review sites fail this rule quietly. "We tested" appears above content assembled from spec sheets, and readers have learned to smell it. The honest alternative is stronger, not weaker: synthesis of owner experience at scale, verified specifications, and triangulated expert sources is demonstrable original analysis, and disclosing it builds the trust that fabricated testing destroys.

## When to use

- Writing product reviews or buying guides when hands-on access is partial or absent
- Setting up the review methodology for a new review or affiliate site
- Adding evidence disclosure to existing review content
- Auditing review content for claims its evidence cannot support
