YMYLとは?対象ジャンルとSEOで求められるE-E-A-Tの考え方

YMYL is not simply a label attached to a business category. Assess whether inaccurate information could cause significant harm to health, safety, financial stability, or the welfare of society. The specific claim and the action it encourages determine the evidence and editorial review it needs.

Understand YMYL through the potential for significant harm

YMYL stands for Your Money or Your Life. Google’s Search Quality Rater Guidelines describe topics with the potential for significant harm. The concept is not equally strong for every page: some topics are clearly YMYL, others are not, and some fall between those positions.

A financial website does not make every sentence carry the same risk. Examine the actual claim and decision. These guidelines provide perspectives for assessing quality; they are not a numeric ranking score assigned directly to your site.

Compare examples across health, finances, safety, and society

The following examples help plan editorial review. They are not medical, legal, or investment advice.

Topic

Potentially consequential claim

Evidence to check

Health

Information that changes treatment or care decisions

Relevant medical evidence and suitable expertise

Money

Instructions affecting investments or taxes

Jurisdiction, conditions, current primary material

Safety

Actions during a disaster

Official current advice and local conditions

Society

Statements about rights or public procedures

Current material from the responsible authority

Record the guideline version and your verification date. The sources for this article were checked on October 12, 2026. A changed document version does not establish why a particular website’s rankings moved.

Assess the actual claim rather than only the category

Within a category, risk depends on the content. A fictional worksheet for sorting household expenses differs from a recommendation to make a substantial investment. A personal record of an experience differs from a treatment instruction.

Consider the severity of a possible error, who could be affected, whether an action can be reversed, and the expertise required. The title alone is insufficient. Review the conclusion, examples, and calls to action because those are often where information becomes consequential guidance.

Distinguish personal experience from expert guidance

A person can describe what they actually experienced. That does not allow the experience to become a universal medical, financial, or legal conclusion. Expert guidance requires relevant competence and, where applicable, jurisdictional context.

The distinctions discussed in Google’s overview of quality evaluation help separate first-hand experience from expertise. Adding a qualification to an author profile does not repair an inaccurate statement. Identify who reviewed the relevant claim and what their review covered.

Check evidence, qualified review, and relevant dates

Match each consequential claim to evidence. Even an official document can be misused if it applies to another country, population, or period. When revisiting an old page, check the content and conditions rather than merely replacing the date.

If a harmful error is found, correcting it comes before improving the author box. Google’s people-first content guidance provides questions about evidence, accuracy, and trust. Presentation should make a real verification process visible, not substitute for that process.

Worked examples: general information versus consequential advice

Consider two fictional editing cases. Case A offers a blank household-expense worksheet with clearly labeled example values. It does not recommend an investment. Case B promises that a product cannot lose money and encourages a financial decision. The latter needs the unsupported guarantee removed and the remaining claims reviewed by someone competent in the subject.

In another example, a user’s account can stay within the experience actually observed instead of becoming a promise for all users. However, adding “in my experience” does not make a dangerous recommendation acceptable. Review the action encouraged and the accuracy of the information itself.

Maintain a correction and update record

A register makes responsibility and review priorities explicit.

Editorial field

Your entry

Claim and action encouraged

________

Potential harm and affected audience

________

Primary URL, jurisdiction, verification date

________

Reviewer and scope

________

Correction, publication decision, next review

________

When a substantial error is identified, communicate the correction in a way that helps affected readers. Do not promise a ranking recovery from the change. Prioritize preventing harmful misinformation and maintaining a process whose evidence and ownership you can explain.
