Start with the author’s actual relationship to the product. A source-based guide, a personal-use account, a seller advertisement and a clinical study should identify themselves clearly. Problems arise when one is presented as another.
Check the original evidence
Follow a citation and read what it supports. Check whether the same formulation was tested and whether the result concerns the outcome in the headline. If a reviewer describes personal testing, look for a clear method, timing and limitations. A photograph alone does not establish a controlled test.
For star ratings, look for accessible individual reviews and a documented collection method. An impressive-looking number without the underlying records is a claim, not a verified finding.
Notice commercial incentives
Affiliate links can compensate a publisher after a purchase. That relationship should be disclosed where readers can see it, rather than hidden after a recommendation. An incentive does not automatically make every fact false, but it is relevant when assessing why a product is promoted.
This site discloses its affiliate relationship and does not claim first-hand testing. Readers can examine the sources independently of the purchase buttons.
Watch for conclusions that outrun the facts
A real product is not necessarily an effective treatment. A refund policy is not clinical evidence. A natural ingredient is not automatically safe for everyone. A study about a different intervention does not establish a result for this one.
Look for a review that states what remains unknown and what would change its conclusion. That is more useful than a dramatic universal verdict built from a handful of anonymous comments.
