YMYL SEO: how Google judges health pages, and what to change
YMYL stands for "Your Money or Your Life": topics where a misleading page could harm someone's health, money or safety. Google holds these pages to its highest standard of trust. For a healthcare site, YMYL SEO means showing who provides the care, promising only what that care can deliver, and making every claim checkable.
What YMYL means, and why health pages are the clearest case
Google's search quality rater guidelines name a class of topics where a poor page can do real harm: health, money, safety and civic life. They call these "Your Money or Your Life" topics, YMYL for short, and ask for the most care on them. A page about the opening hours of a bakery can be a little careless. A page about whether a lump needs checking cannot.
Almost every page on a clinic, dental, aesthetic or telehealth website is YMYL. Treatment pages describe what will happen to a body. Provider pages ask a reader to trust a stranger with their health. Even a pricing page influences a medical decision. So the standard below applies to the whole site, not only to the clinical articles.
What Google looks for: trust first
The guidelines describe four qualities: experience, expertise, authoritativeness and trust, written as E-E-A-T. Trust sits at the center. A page can show expertise and still be untrustworthy if it overstates what it offers or hides who is behind it.
Two points get lost in most SEO advice:
- Quality raters do not rank pages. Their ratings help Google check whether its ranking systems are doing what they should. The guidelines are a description of the target, not a list of switches.
- There is no single trust number to raise. Google's systems use many signals that approximate these qualities. What you control is whether each page gives a careful reader, and a search engine, good reason to trust it.
Who, how and why: three questions every health page should answer
Google's own guidance on helpful content asks three questions of any page. On a health site, each has a concrete answer.
- Who wrote it, and who checked it? A named author and a named clinical reviewer, with credentials stated exactly as held and a link to a profile page. "Our expert team" answers nothing.
- How was it produced? Where the information comes from, when it was last reviewed, and what the service does and does not include.
- Why does the page exist? To help a reader understand a condition or decide on a next step. A page written to rank for a phrase, with the help added afterwards, reads that way.
The phrasing that undermines trust
Most health sites do not lose trust through what they leave out. They lose it through four habits of phrasing that make a page promise more than the care can deliver.
- Certainty. Outcomes stated as facts: "eliminates", "permanent", "guaranteed results". (FR-01)
- Superlatives without a source. "The leading clinic", "the most experienced team". (FR-07)
- Numbers nobody can check. Patient counts, success rates and review totals with no source or date. (FR-08)
- Urgency. "Book now before it gets worse" on a page about symptoms.
Treatment aims to ease back pain. Your clinician will explain what to expect in your case.
The rewrite keeps the point of the sentence and adds no new claim. It moves the promise from a certainty to an aim, and points the reader to the person who can judge their case. That is the shape of most careful rewrites on a health page.
Named authority, on the page and in the code
The single most common gap on clinic websites is that no page says who is behind it. Fix it in three places:
- On every clinical page, a short byline: who wrote it, who reviewed it, and when. (EA-01)
- On a profile page per clinician, with the credential worded exactly as on their registration, and used the same way everywhere else on the site. A headline that calls someone a specialist while the profile says otherwise is a finding in its own right. (EA-05)
- In the structured data, marking up the practice and its clinicians with the same names and titles the pages show. (EA-04)
Structure that search engines and AI assistants can read
Trust is also a matter of being easy to read correctly. Three structural habits help a person, a search engine and an AI assistant reach the same understanding of a page:
- An answer block under the main heading: 45 to 60 words that say what the page is about, for whom and where, before any detail. (ST-02)
- A bridge to the consultation: clinical detail that ends by pointing to the person who can apply it to the reader's case, rather than to a booking button alone. (ST-03)
- FAQ answers that stand alone, so that any one of them makes sense when quoted on its own.
Why AI answers raise the stakes
AI assistants such as ChatGPT, Perplexity and Google's AI Overviews answer health questions by quoting short passages from pages they consider reliable. That changes two things for a healthcare site. A careful, self-contained paragraph is more likely to be quoted, and quoted accurately. And an overstated sentence can now travel without the context around it, in an answer the reader may trust more than your page. Writing every key sentence so that it is still true when quoted alone is the same discipline YMYL asks for anyway.
What to leave to your lawyer
Some wording on a health site carries legal weight, and the rules differ by state and by country. These belong with a lawyer, not with an SEO review:
- Credentials, specialty titles and registration statements. (LR-01)
- Testimonials, reviews, ratings and before-and-after photos. (LR-07)
- Prices, offers and financing.
- Who may be treated, from where, and across which borders.
- Consent, data handling and privacy wording.
Our reviews list these separately, with the quote and the page, and suggest no wording for them.
Frequently asked questions
What does YMYL stand for?
"Your Money or Your Life". Google uses the term in its search quality rater guidelines for topics where a low-quality page could hurt a reader's health, financial stability, safety or wellbeing. Medical and health information is the clearest example.
Is E-E-A-T a ranking factor?
Not as a single number. Experience, expertise, authoritativeness and trust describe what Google's ranking systems aim to reward, and its systems use many signals to approximate them. On health topics, trust weighs the most.
Does every health page need to be written by a doctor?
No. It needs to be clear who wrote it and who checked the medical content, with credentials stated exactly as held. A named clinical reviewer on each clinical page is the practical standard.
How long do changes take to show in search?
It varies: from a few weeks for a rewritten title and description to several months for wider trust signals. Measure it in Search Console against the weeks before the change, and change one group of pages at a time.
