An electrician has just put two new pages on her website. One is called "Wallbox installation in Dortmund" and describes what her business does and how to book an appointment. The other is called "Breaker keeps tripping: what to do?" and walks readers through narrowing down the cause step by step. Same business, same domain, same author. To Google they are still two very different cases, because only the second one can get someone hurt if the text is wrong.
That is what YMYL is about. The term sounds like jargon for health portals and banks, but it applies just as much to tax advisors, physiotherapists, insurance brokers, online shops and trades businesses with a how-to section. This piece explains what YMYL means according to Google, how to judge whether a given page falls under it, and what you can actually do about it.
YMYL means: a mistake can hurt someone
YMYL stands for "Your Money or Your Life". The term comes from the Search Quality Rater Guidelines, the handbook external raters use when they assess search results for Google. The current version is dated 11 September 2025. It defines YMYL topics as those that could significantly impact the health, financial stability or safety of people, or the welfare or well-being of society.
A topic gets there in one of two ways. Either it is dangerous in itself, such as self-harm or criminal acts. Or it becomes dangerous when the content is inaccurate. For small websites it is almost always the second case. The guidelines give examples such as the symptoms of a heart attack, how to invest money, what to do in an earthquake or who is allowed to vote. The harm only comes when a detail is wrong and someone acts on it.
For context: the rater guidelines are not a ranking algorithm, and Google says individual ratings do not directly affect rankings. In its documentation for site owners, however, Google states that its systems give even more weight to content with strong E-E-A-T on such topics. What E-E-A-T is, and why there is no score for it, is covered in E-E-A-T signals.
Four categories, one of them reworded
The September 2025 version of the guidelines revised the YMYL definitions. There are now four categories:
| Category | What it covers |
|---|---|
| Health or Safety | mental, physical and emotional health, and any form of safety, including safety online |
| Financial Security | anything that could damage a person's ability to support themselves and their family |
| Government, Civics & Society | topics affecting groups of people, issues of public interest, trust in public institutions, election and voting information |
| Other | anything else that could hurt people or harm the welfare of society |
The third category is the reworded one. Most small businesses rarely touch it, though it can apply when a nonprofit explains dealings with public authorities or a law firm writes about residence permits. For practices, firms, financial services, shops and trades, the first two categories are the ones that matter.
YMYL is decided per page, not per industry
The most common mistake is to ask "Is my industry YMYL?". Google assesses topics, which means individual pages. According to the guidelines, what counts is whether the topic itself could significantly affect health, money or safety, not whether some harm could be constructed around it.
On top of that, YMYL is a spectrum, not a switch. Google distinguishes "clear YMYL", "may be YMYL" and "not YMYL" and gives paired examples. When to go to the emergency room is clear YMYL. How often to replace a toothbrush is a health topic, but one people casually discuss with friends, so it only may be. How often to wash jeans is not. According to Google, most topics are not YMYL.
That gives you two test questions for any page. Would a careful person rather ask an expert about this, because even small mistakes could cause harm? Then it leans YMYL. Would most people settle it over coffee with friends? Then it probably does not.
Back to example-electric.com. The wallbox page describes a service, and a mistake on it costs at most a job. The breaker guide invites people to do it themselves. If it does not say when to keep your hands off the consumer unit, someone could get an electric shock. Tellingly, the rater guidelines use this very trade to illustrate expertise: rewiring advice from a skilled electrician is something different from advice by an old-house enthusiast with no electrical knowledge.
Which small businesses are typically affected
The table below is an assessment derived from the four categories. Google does not publish a list by industry, and it always comes down to the individual page.
| Business | Assessment | Why |
|---|---|---|
| Doctor, dentist, psychotherapist | clear YMYL | symptoms, treatments, medication |
| Physiotherapy, occupational therapy, midwife | how-to content clear YMYL, service pages medium | health, exercise instructions |
| Pharmacy, including online | clear YMYL | health plus payment |
| Naturopath, alternative therapies | clear YMYL, especially sensitive | efficacy claims |
| Tax advisor, payroll | clear YMYL | deadlines, amounts, financial consequences |
| Insurance and financial broker | clear YMYL | retirement, cover, loans |
| Law firm | clear YMYL | legal consequences for money or liberty |
| Estate agent, property management | YMYL | major financial decisions |
| Online shop with checkout | YMYL because of the transaction | payment data, customer service |
| Electrical, gas and heating | YMYL for how-to and safety content | service pages less critical |
| Coaching | borderline | career coaching hardly, nutrition, trauma or debt clearly |
| Painter, carpenter, agency, restaurant | mostly not | exceptions: mould, asbestos, structural work, allergens |
The online shop does not become a YMYL case because of its products but because people pay there. The guidelines require extensive contact information from any site that handles payments or asks for personal data. And coaching shows how fluid the line is: the same person writes about job interviews on one page and about debt on the next.
Why YMYL pages face a higher bar
For clear YMYL topics, the guidelines call for "very high Page Quality rating standards". That shows up in three places.
Accuracy is measured against expert consensus. On informational YMYL pages, what counts is whether the content matches what is well established among experts. Personal experience is explicitly valuable, such as a patient's account of her treatment, as long as it does not contradict that consensus. Some information, according to Google, has to come from experts though, for example on medication during pregnancy, filling out tax forms or retirement planning.
Reputation is judged by experts. Raters are supposed to research what others say about a website, and for YMYL topics mainly what experts say. Recommendations from professional societies count as strong evidence. Raters are told to read a site's claims about itself with scepticism, and a bare "I'm an expert" is not enough.
Missing accountability leads straight to the lowest rating. Among the criteria for "Lowest", the guidelines list a complete lack of information about who is responsible for the website and its content, on YMYL pages and other pages that require trust. A YMYL page that is clearly written without expertise also gets Lowest, and so does one that invents qualifications.
On a page about washing jeans, a missing author is a cosmetic flaw. On a guide to drug interactions, it is a reason not to trust the page.
What this means for your content
None of this costs money, only care. None of the points guarantees rankings, but they remove the typical weaknesses of YMYL pages.
An expert reviews it, by name. Every YMYL text gets a visible line stating who wrote it and who reviewed it, with professional title and date: "Reviewed by Claudia Example, certified tax advisor, on 28 September 2026." The name links to a page that shows who this person is. How to build that is covered in author pages. You can add markup such as reviewedBy as well, but Google does not document any use of it. What readers see is what matters.
Cite sources, the original ones. Google's own self-assessment questions explicitly ask about clear sourcing. On a tax page that means the statute or the official guidance. On a health page, the clinical guideline from the professional body. Another blog saying the same thing is not a source.
Being current is a safety issue. Tax allowances, grant conditions, insurance coverage and technical standards change. A guide from 2022 can be wrong today without a single word having changed. Give every YMYL page a fixed review date and an honest "last reviewed on" line that you only change when you have actually checked it. How to find pages that are going stale is described in updating existing content.
No promises of cures, no promises of returns. "Guaranteed to relieve back pain" and "a safe five percent a year" can get you into legal trouble, and the rater guidelines take a dim view of such promises: their example of harmfully misleading content is the claim that buying lottery tickets is a guaranteed way to save for retirement. Write what a service can do, under which conditions and for whom it is not suitable.
State the limits and refer to professionals. A good YMYL text says where it stops: "These steps help you narrow down the cause. Work inside the fuse box belongs in the hands of a qualified electrician." A general guide cannot judge an individual case, so the note about when personal advice is needed belongs in the text, not in the small print. For practices and firms, that is the natural next step anyway.
Mandatory disclosures double as trust signals
The rater guidelines explicitly acknowledge that different locales have their own conventions for what information a website should provide. If you operate in Germany, Austria or Switzerland, it is reasonable to assume, though Google has not confirmed it, that a complete legal notice (Impressum) is exactly what a local rater looks for under "who is responsible". The following notes are not legal advice; your professional chamber, chamber of commerce or a lawyer is the right place for your specific case.
In Germany, the legal notice now sits in § 5 DDG. On 14 May 2024, the Digitale-Dienste-Gesetz (DDG) replaced the old Telemedia Act (TMG). The required details, such as name, address, a fast electronic way to get in touch, register entry and VAT ID, have changed little in substance. A notice that still cites "§ 5 TMG" mostly signals one thing: nobody has looked after this page in a long time.
Regulated professions disclose more. For professions such as doctors, pharmacists, tax advisors or physiotherapists, § 5 DDG additionally requires the statutory professional title together with the country that awarded it, the professional rules plus where to read them, and the professional chamber if you belong to one. Activities that need official authorisation, such as insurance brokerage or estate agency, also name the supervisory authority, and insurance intermediaries give their registration number.
These details are the cheapest form of verifiable expertise there is, because anyone can check them in public registers. That kind of evidence is what the guidelines mean when they refuse to accept self-description alone. Which registers and directories qualify is covered in website trust signals.
Health advertising has tight limits. In Germany, the Heilmittelwerbegesetz (HWG), the law on advertising medicines and treatments, prohibits misleading advertising in § 3, for instance claiming effects that do not exist or falsely suggesting success is certain. § 11 restricts advertising to the public further, including case histories and third-party statements used in an abusive or misleading way, and bans before-and-after images for cosmetic surgery. Factual information about qualifications, focus areas and services remains allowed. For food supplements, the EU Health Claims Regulation applies on top: only authorised health claims are permitted, and no food may be promoted as preventing, treating or curing disease.
Law and Google point in the same direction here: showing qualifications, method and sources is safer than testimonials, which health advertising law restricts. Austria and Switzerland have their own rules, in Austria for instance § 5 ECG and § 25 of the Media Act, in Switzerland the Unfair Competition Act for online shops.
AI text on YMYL pages: allowed, but not unchecked
Google does not penalise text because an AI helped write it. The guidelines state explicitly that using generative AI alone does not determine effort or page quality. Mass-produced pages without added value, on the other hand, count as "scaled content abuse" and get the lowest rating, however they were made.
On YMYL pages, the risk of an unchecked AI text lies in the substance. Language models can invent deadlines, mix up allowances or transfer the legal situation of one country to another. One of the guidelines' Lowest examples is an article about cancer that opens with a language model saying it has no access to real-time data, and breaks off mid-sentence.
So the rule is: AI may draft, a professional checks every figure and puts their name under it. That matches the EU AI Act, which since 2 August 2026 requires AI-generated text on matters of public interest to be labelled, unless a human has reviewed it and someone holds editorial responsibility. How far that reaches for a company blog has not been settled, and chatbots have their own disclosure duties.
What you do not need
YMYL quickly gives small businesses the feeling they have to become a media brand. You don't.
You do not need a Wikipedia entry or press coverage. The guidelines say explicitly that small websites often have little or no reputation information and that this is not indicative of high or low quality. Raters then give the other criteria more weight, and high ratings remain possible.
You do not need a doctorate for every text. For exercises against neck tension, the physiotherapist is the right expert. What counts is relevant expertise, not the highest title.
And you do not need to treat every page like an emergency guide. Service pages, directions and case studies do not need expert review with a list of references. The effort belongs where a mistake can do harm. Avoiding YMYL topics altogether would be the wrong conclusion, though: for practices and firms, a reviewed guide is often how people find them before they search for them by name.
Where to start
- List every page where you explain, advise or give instructions, and use the two test questions to mark which are clearly YMYL.
- Check whether those pages visibly show the author, the expert review and an honest review date, and add what is missing.
- Read each YMYL text asking which figure, deadline or statement might no longer be true, and back the important ones with the original source.
- Remove promises of cures or returns, and add where the text's limits are and when someone needs a professional.
- Check your legal notice against the rules where you operate, including chamber, title and professional rules for regulated professions, and ask your chamber if in doubt.
- Link from your team or author pages to public registers where people can find you.
- Set a fixed review date for every YMYL page, every six or twelve months depending on the topic.
How Traffalyzer helps
No tool decides whether a page is YMYL, and Traffalyzer cannot measure E-E-A-T, because no such score exists. The scan checks the technical groundwork your editorial work sits on.
It counts how many pages carry a publication or modification date in their metadata (article:published_time, article:modified_time) and flags modification dates that are not credible: the page reports a fresh date, but Traffalyzer has seen no change to its content in weeks. The usual cause is a theme that sets the date anew on every page view, and that devalues any honest review date. The scan also counts pages with author metadata (meta name="author" or article:author). According to its own documentation, Google does not use these tags; what counts there is the visible byline and author in Article markup. The number is still useful, as a pointer for other systems such as AI assistants, feed readers and social networks, and as an indicator of whether authors are maintained at all.
The scan also measures structured data coverage and checks HTTPS. The "Content to refresh" list suggests pages that are going stale, and with Search Console connected you can see whether rankings rise after your changes. The expert review itself stays with you.
Frequently asked questions
What does YMYL mean?
YMYL stands for "Your Money or Your Life". Google uses it for topics where inaccurate content could significantly affect people's health, financial stability or safety, or the welfare of society. The term comes from the Search Quality Rater Guidelines, currently in the version of 11 September 2025.
Is my whole website YMYL if I am a doctor or a tax advisor?
Not every page. Google assesses topics, and therefore individual pages, and YMYL is a spectrum. Guides about symptoms or tax deadlines are clear YMYL, the directions page is not. In practices and firms the share of such pages is high, though, so care pays off across the whole site.
Is YMYL a ranking factor?
Not as a value of its own. YMYL is a term from the guidelines for human raters, whose ratings do not feed directly into rankings. Google does say its systems give more weight to content with strong E-E-A-T on such topics. A lack of trust weighs more heavily on YMYL pages.
Can I use AI-written text on YMYL pages?
Yes. Google assesses quality and effort, not origin. On YMYL pages, though, every figure, deadline and recommendation should be checked by a professional who stands behind it by name. Mass-produced pages without added value count as spam, however they were created.
Do I have to show a date on YMYL pages?
Not by law, but on topics that change, a visible and honest review or update date is an important signal for readers. Google recommends a clearly labelled date such as "Updated" and the matching date in the markup. Only change it when you have actually reviewed or changed the page.
