Healthcare Website SEO: E-E-A-T, Access and Trust

The YMYL bar

Google's systems give more weight to strong E-E-A-T for topics that could significantly impact health, financial stability, or safety, and of those aspects, trust is most important. [Google Search Central, Creating helpful content]

Google's SEO Starter Guide states plainly that E-E-A-T is not itself a ranking factor, so the work is about genuine trust signals, not a checklist to game. [Google Search Central, SEO Starter Guide]

None of the guidance above should be read as clinical advice; it addresses marketing, advertising, privacy, and patient education only, and any clinical question should go to a licensed provider.

Accessibility as trust infrastructure

The Department of Justice has consistently taken the position that the ADA's requirements apply to all the goods, services, privileges, or activities offered by public accommodations, including those offered on the web. [ADA.gov, Guidance on web accessibility and the ADA]

DOJ notes it does not have a regulation setting out detailed technical standards, and points to WCAG and Section 508 standards as helpful guidance. [ADA.gov]

Practices that build compliance into the workflow from the outset tend to spend less time on rework later, since retrofitting consent language or claim substantiation after publication is far more expensive than designing for it up front.

• Documented barriers include poor color contrast, color-only information, missing alt text, uncaptioned video, inaccessible forms, and mouse-only navigation. [ADA.gov]
• WCAG 2.2 was published on October 5, 2023 with an update on December 12, 2024, with success criteria at levels A, AA, and AAA under the perceivable, operable, understandable, and robust principles. [W3C, WCAG 2 Overview]

Author, reviewer, citation and update conventions

Structure patient education content to answer the specific question first, then add context, and make it self-evident who wrote or reviewed it.

A visible, dated review credit from a named clinician does more for trust than any design element, since it directly answers the question a health-topic visitor is implicitly asking: who is responsible for the accuracy of what I am about to read.

Assign clear ownership for compliance review inside the marketing function itself, rather than treating it as something legal handles entirely separately, since the fastest catches happen when the person writing the content already knows the rules.

Structured data for clinics and practitioners

Structured data must match visible page content and use the most specific applicable schema.org type available for the practice or practitioner. [Google Search Central, General structured data guidelines]

Train every new hire who touches patient-facing marketing on this rulebook specifically, rather than assuming general marketing experience transfers cleanly, since the constraints in this category diverge sharply from ordinary consumer marketing practice.

Technical baseline

Google's page experience checks include HTTPS, mobile display, ad load, intrusive interstitials, and distinguishable main content, with Core Web Vitals used by ranking systems. [Google Search Central, Understanding page experience]

Keep a running file of every claim made in marketing materials along with its supporting evidence, so a compliance review or an unexpected audit can be answered quickly rather than reconstructed after the fact.

QA and governance

A clean automated accessibility report does not necessarily mean everything is accessible, so pair automated tools with manual checks on a regular schedule. [ADA.gov]

Assign accessibility QA to a named owner with a recurring calendar slot, the same way you would assign clinical content review, since without ownership this work tends to slip once the initial launch push is over.

Where guidance in this space is still evolving, as with tracking technology rules, default to the most conservative reading available rather than the most permissive one, since the cost of over-caution is far lower than the cost of a real violation.
