Definition
YMYL, short for 'Your Money or Your Life', is the term Google's Search Quality Rater Guidelines use for topics that could significantly affect a person's health, financial stability or safety, or the welfare of society. Pages on these topics get the most scrutiny, because inaccurate information can cause real harm.
The September 11, 2025 edition of the guidelines groups YMYL topics into four categories. Health or Safety covers topics that could harm mental, physical or emotional health, or any form of safety, including safety online. Financial Security covers topics that could damage a person's ability to support themselves and their families. Government, Civics and Society covers topics that could negatively affect groups of people, issues of public interest and trust in public institutions; the 2025 edition renamed this category and added election and voting information explicitly. Other covers topics that could hurt people or the welfare of society in other ways.
The guidelines add that a topic is YMYL because of its subject, not because a harmful page about it could exist. A page about the science of rainbows is not YMYL; a page about medication dosages is.
Google's helpful content guidance explains how this affects ranking: its systems 'give even more weight to content that aligns with strong E-E-A-T' for YMYL topics, and for those topics content 'must be highly accurate and consistent with established expert consensus'. The rater guidelines also distinguish when experience is enough. A first-hand account of living with a condition or using a retirement account can be valuable, while advice on dosages or investment allocation calls for expertise.
AI answers on YMYL topics tend to lean on institutional sources. In Promptwatch's October 2026 healthcare citation report, government and public health sites earned 7.06% of all ChatGPT citations for healthcare prompts and NIH and its research databases 5.46%, far more than hospitals and clinics (0.89%). Google applies its core ranking and quality systems to AI Overviews and AI Mode, and its spam policies have explicitly covered those answers since May 2026. Assistants also commonly add disclaimers or suggest consulting a professional on medical, legal and financial questions.
For publishers and brands in YMYL categories, the practical requirements are well known but often skipped:
- Content written or reviewed by qualified people, named on the page with credentials that can be checked.
- Citations to primary sources such as clinical guidelines, regulations, official statistics and peer-reviewed research.
- Visible review and update dates, with content checked when rules or guidelines change.
- Clear scope and disclaimers, for example which jurisdiction legal content applies to.
- About, contact, editorial and corrections policies that show who is accountable.
This is where E-E-A-T and author authority matter most, and where errors repeated by AI systems, a form of AI hallucination, do the most damage. Fact-check pages marked up with ClaimReview and careful sourcing help keep wrong claims from spreading.
Examples of YMYL (Your Money or Your Life)
- A telehealth company has every condition page reviewed by a licensed physician, names the reviewer with her registration number, and lists the clinical guideline each page follows with its publication year.
- A budgeting app's blog adds jurisdiction labels to tax articles after users in Canada followed advice written for US filers, and updates each article within a month of annual tax changes.
- A county elections office rewrites its voter registration page with deadlines in the first paragraph and a 'last verified' date, since election and voting information has been explicitly YMYL since September 2025.
- A supplement retailer removes claims that a product 'cures anxiety' from product pages and links instead to the specific studies behind narrower, accurate claims.
