What Is YMYL? Why Google Holds Medical Websites to a Higher StandardGoogle's own definition, the four YMYL categories, and five things a practice website should show.

YMYL stands for "Your Money or Your Life." It is Google's name for topics where bad information could harm a person's health, financial stability, or safety. Medical content is a YMYL topic. Google holds it to a higher standard than a recipe or a movie review. This guide quotes Google's own documents and shows what a practice website should do about it.

YMYL at a glance

• The term comes from Google's Search Quality Rater Guidelines. The current edition is dated September 11, 2025.
• Google lists four YMYL categories. Health or Safety is the first.
• Google says its systems "give even more weight to content that aligns with strong E-E-A-T" on YMYL topics.
• E-E-A-T is not a ranking factor by itself. Google says so directly.

What does YMYL mean?

YMYL means a topic that carries a high risk of harm. Google's rater guidelines explain that some topics could significantly affect people's health, financial stability, or safety, or the well-being of society. The guidelines state: "We call these topics 'Your Money or Your Life' or YMYL."

What are the four YMYL categories?

A condition page, a treatment page, and a medication article all fall under Health or Safety. An office-hours page does not carry the same risk.

Why does Google hold medical websites to a higher standard?

Google holds medical websites to a higher standard because wrong health information can hurt people. The rater guidelines state that Google has "very high Page Quality rating standards" for pages on clear YMYL topics. The guidelines also place medical treatment information in a category called "Information or advice best left to Experts."

Google's public guidance for site owners says the same thing in plainer words. Its systems "give even more weight to content that aligns with strong E-E-A-T" for topics that could affect health, financial stability, or safety.

What is E-E-A-T?

E-E-A-T stands for experience, expertise, authoritativeness, and trustworthiness. Google says: "Of these aspects, trust is most important."

• Experience

  The author has done the thing. A surgeon who performs the procedure writes about recovery.

• Expertise

  The author has the training. Degrees, board certification, and licenses are shown.

• Authoritativeness

  Others recognize the source. Hospitals, associations, and news sites mention the practice.

• Trust

  The page is accurate, honest, and safe. Google calls this the most important aspect.

What questions does Google ask about content quality?

Google publishes self-assessment questions for site owners. Three apply directly to a medical page.

1. "Is this content written or reviewed by an expert or enthusiast who demonstrably knows the topic well?"
2. "Does the content have any easily-verified factual errors?"
3. "If someone researched the site producing the content, would they come away with an impression that it is well-trusted or widely-recognized as an authority on its topic?"

Read each health page on your site and answer the three questions honestly. A "no" tells you what to fix.

What should a medical website show to meet the YMYL standard?

1. 1

   Name the author or reviewer

   Put a clinician's name on every health page. Google says: "We strongly encourage adding accurate authorship information."

2. 2

   Show credentials

   Link each name to a provider page with degree, board certification, and license state.

3. 3

   Cite sources

   Link clinical claims to published sources. The rater guidelines say consistency with expert consensus is important for medical advice.

4. 4

   Date the review

   Show when a clinician last reviewed the page. Update the date only after a real review.

5. 5

   Make the practice easy to verify

   Show the address, phone, and hours as text. Link the Notice of Privacy Practices in the footer.

Does YMYL matter for AI answers too?

Yes, for Google's AI features. Google says a page must be indexed and eligible for a snippet in Google Search to appear as a supporting link in AI Overviews or AI Mode. A health page that Google Search does not show cannot be cited there. Our guide to AEO for healthcare covers what Google and ChatGPT require.
