Running a health or medical website used to mean buying a domain, uploading some articles, and waiting for search traffic. That model still works in most verticals. In healthcare, it has not worked for years. Google holds health publishers to standards that do not apply to general interest or commercial sites. A practice like Lumine Dermatology & Laser Clinic needs to signal clinical authority across every page it publishes, not just the “About” section, because the algorithms deciding whether a result is safe to surface apply stricter criteria to medical content than to almost any other category.
That stricter category is YMYL: Your Money or Your Life. A page about a procedure such as skin biopsy belongs in YMYL because a reader might make a real decision, seeking or delaying a test, based on what they read. Errors on a recipe blog carry low stakes. Errors on a cancer screening page do not. E-E-A-T, which stands for Experience, Expertise, Authoritativeness, and Trustworthiness, is the framework Google uses to evaluate whether a site meets the standard YMYL content requires.
What E-E-A-T Actually Means for Health Sites
The acronym has four components, but they do not carry equal weight. Trustworthiness sits last alphabetically and is, by most readings of Google’s Search Quality Rater Guidelines, the most important. A site can show signs of expertise and still fail the review if it has no privacy policy, vague contact information, or a checkout flow that makes users uncomfortable. Trustworthiness is a baseline filter that runs before the other signals are evaluated, which is why fixing it first makes practical sense for any health site audit.
The addition of Experience in 2022 changed what counts as a credible author. It is no longer enough to list credentials in a sidebar bio; the content should reflect firsthand knowledge. A dermatologist who has performed hundreds of procedures and writes from that clinical vantage creates something a generalist synthesizing published studies cannot replicate.
Authoritativeness describes how the broader web perceives a source, not just how the source presents itself. External links, mentions in medical publications, and citations from recognized institutions all contribute to it. Building authority takes years, which is one reason newer health sites face a steeper ranking curve than established platforms even when their content is more accurate.
YMYL Classification and What It Changes
Google has never released a fixed list of YMYL topics. The Search Quality Rater Guidelines describe the category broadly: pages that could significantly affect someone’s health, safety, financial stability, or happiness if the information is wrong or misleading. Medical content sits near the center of that definition. Symptom guides, treatment overviews, drug interactions, and diagnostic procedures all qualify, and all are evaluated under stricter criteria than general commercial content.
The practical effect on ranking is a raised floor. In most niches, a reasonably authoritative domain can carry pages with modest content quality. In YMYL health content, thin pages tend to be filtered out rather than just ranked lower. Quality becomes a prerequisite rather than a competitive advantage, which is an important distinction when planning a content strategy around a medical client or property.
Building Author Credentials Google Can Verify
The most concrete E-E-A-T improvement available to most health sites is making author credentials verifiable, not just visible. A name and headshot on an article is a start. What actually moves the needle is an author bio that links out to professional profiles: medical licensing databases, peer-reviewed publications, university faculty pages, or recognized professional associations in the relevant specialty.
For each author, MedicalWebPage or Article structured data with a reviewedBy property pointing to a known external reference makes that connection machine-readable. Sites that list medical staff prominently on their homepage but omit bylines from individual articles have the most common gap in this area. Homepage authority does not transfer to content pages automatically.
One pattern that consistently fails quality review: a detailed article on a medical procedure written by an unnamed editorial team. The content may be accurate. Without a name, credentials, and a link to a verifiable profile, quality raters cannot confirm that. Google’s guidelines are explicit that the absence of clear authorship on YMYL content is itself a trust signal, a negative one, and it tends to drag otherwise solid pages down.
Citations, Structured Data, and Outbound Links
Citing authoritative sources does two distinct things that are easy to conflate but worth keeping separate. Readers see it as a credibility signal that affects whether they trust advice enough to act on it. According to the National Institutes of Health, people evaluating online health information look first for transparency about who wrote it and what institution backs it. An article that cites nothing gives those readers no anchor for that judgment.
Crawlers read outbound links differently, as a network signal. A page that references .gov or .edu sources embeds itself in a graph of quality domains, separate from reader trust but reinforcing the same underlying quality. Placement matters here more than most webmasters realize: a citation that grounds a specific claim in the paragraph where the claim is made reads as editorial. A sources section at the foot of the page reads as an afterthought, and most content management systems make inline citation easy enough that there is no real excuse for that approach.
Running a Practical E-E-A-T Audit
Google publishes the Search Quality Rater Guidelines publicly, and the medical sections are specific enough to use as a page-by-page checklist. The fastest audit is to read ten pages from your site through those guidelines and ask, for each: who wrote this, how can a reader verify that person’s qualifications, and what happens if the information is wrong? If no good answer surfaces within 30 seconds of looking, the page has an E-E-A-T problem regardless of its keyword targeting.
The FTC’s consumer guidance on buying health products and services online notes that consumers are increasingly skeptical of medical claims they cannot trace to a clear, verifiable source. Quality raters apply the same lens. Older content that was never attributed, commercial pages making efficacy claims without clinical evidence, and mobile pages where consent banners obstruct the main content are three areas where health sites most commonly fall short.
One area worth checking separately is schema completeness. A site that has Article schema but no author credentials in the markup is leaving readable information inaccessible to crawlers. Running the Schema Markup Validator alongside a content audit surfaces those gaps. Many health sites find structural issues there that take a few hours to close but produce measurable improvements in how pages are parsed and surfaced in search results.
