3-1. Comparative Review Policy
Greenkeys strictly adheres to the following requirements when making comparisons with other companies’ products in its product reviews, based on the Consumer Affairs Agency’s ” Idea under the Act Against Unjustifiable Premiums and Misleading Representations Concerning Comparative Advertising “.
This ensures that readers are not misled and that fair and objective information is provided.
- Objective substantiation: The basis for comparison (e.g., performance figures or survey results) should be substantiated by established methods (e.g., third-party data, actual test results, etc.). Whenever possible, they will be supported by photos, spec tables, or external links. However, this does not apply to those items for which we have evaluated that not only an objective evaluation but also a subjective evaluation is necessary. (see below)
- Accurate citations: Accurately cite substantiated facts and figures and clearly state how the research was conducted. We do not arbitrarily excerpt only a portion of the data, but properly present the whole picture.
- Fair Method: Selection of comparables is not arbitrary; we choose products of comparable caliber. We clearly state not only the advantages but also the relevant disadvantages, and we do not hide unfavorable information. We strive to avoid unfair comparisons of products in different price ranges and categories.
- Violation prevention: No comparisons will be made that do not meet the above requirements and, if necessary, a note will be made in the article stating that the basis for the comparison is subjective. If a reader points out a problem, we will promptly check and correct it.
3-2. Disclosure of PR and Offerings
- In accordance with stealth marketing regulations (enforced on October 1, 2023), reviews using donated products (products provided free of charge for promotional purposes by companies, etc.) should clearly state in a prominent position in the article that the review uses donated products, such as “#PR,” “Product review” or “Conflict of interest: product provided. This will allow the reader to clearly see the advertising nature and promotional elements of the article. This will help readers recognize the advertising nature and promotional elements.
- When making comparisons within review content using the offerings, we will apply the above “3-1. Comparative Review Policy” and make every effort to avoid arbitrary expressions that may appear to favor the offeror. Evaluations will be conducted fairly, regardless of whether the offerings are provided or not.
- If affiliate links are included, we will maintain their independence so that the content of the comparison is not influenced by revenue.

- The presence or absence of advertising links is clearly indicated in the article.

Handling of Conflicts of Interest
- Any special relationship between the author and the company, such as product offerings, sponsorships, or contributions, will be clearly indicated in the article.
