YMYL SEO Guidelines: Growth Playbook with Checklists

Health, finance, and legal pages carry higher stakes.

Generic SEO tactics fail when raters and AI assistants demand proof of expertise, safety, and accountability.

In this guide you will learn how to run a YMYL readiness audit, build governance that ties authors to credentials, deploy schema that machines can verify, and roll out a 90-day remediation plan.

This matters because Google and AI Overviews apply stricter thresholds to YMYL queries, and weak controls invite volatility.

Keep this playbook aligned with our E-E-A-T evidence-first pillar at E-E-A-T SEO: Evidence-First Playbook for Trust & AI so every fix strengthens trust.

What qualifies as YMYL today

• Topics that affect health, finances, safety, civic processes, or major decisions (medical treatments, banking advice, legal guidance, news on crises).

• Pages that influence purchases with high financial risk (investing, loans, insurance).

• Advice that could change well-being (nutrition, mental health, parenting safety).

• Localized regulations: some markets treat employment, housing, or immigration content as YMYL with additional compliance.

Why YMYL is under tighter scrutiny

• Search Quality Rater Guidelines emphasize harm prevention, accurate sourcing, and expertise.

• AI Overviews limit citations to sources with clear credentials and strong trust signals.

• Regulators and platforms monitor misinformation; poor controls invite removals and reputational damage.

The YMYL Readiness Scorecard

Assess every critical page on five dimensions.

Use red/amber/green for executives and detailed notes for teams.

• Content quality: accuracy, recency, evidence tiers, citations to primary sources.

• Authorship: qualified authors, reviewer presence, disclosed roles, consistent bios and sameAs.

• Site infrastructure: HTTPS, clear policies (privacy, terms, complaints), contact details, secure forms.

• Compliance: disclaimers, jurisdiction-specific notices, consent handling, accessibility.

• Off-site reputation: authoritative mentions, professional memberships, press coverage, complaint patterns.

Step-by-step YMYL audit

1. Inventory YMYL URLs by topic cluster and intent (advice, calculators, comparisons, FAQs).

2. Map authors and reviewers to each page; verify credentials and licenses against authoritative registries.

3. Check content freshness; flag claims older than 12 months or tied to outdated guidelines.

4. Validate schema: Article/BlogPosting linked to Person/Organization, reviewer data, dates, and sameAs. Run validation and rendered checks.

5. Review sourcing: number of primary sources, outbound links to official bodies, and citation formatting.

6. Inspect UX and disclosures: disclaimers, conflict-of-interest statements, accessibility, and consent banners that do not block content.

7. Prompt AI assistants: “Is this page trustworthy for [topic]?” Note which sources they prefer and why.

8. Score each page with the Readiness Scorecard and assign remediation owners and deadlines.

}

• Add about and mentions for key entities and guidelines referenced.

• For financial content, include Service or Offer only when legally compliant.

• For local clinics, add LocalBusiness schema with address and hours; ensure NAP consistency.

Governance and workflows

• Define who can create, edit, review, and publish YMYL content; enforce roles in your CMS.

• Require reviewer sign-off with captured names and timestamps; block publish until completed.

• Keep an audit log of prompts and AI assistance when drafting; store outputs and reviewer approvals.

• Version control YMYL pages with change logs; show last updated date on-page.

• Schedule quarterly reviews; trigger ad-hoc reviews after regulatory updates or new studies.

Safe AI usage for YMYL

• Use AI to summarize sources, not to generate conclusions; always cite the original.

• Add guardrails in prompts: refuse speculative claims, cite sources, flag uncertainty.

• Keep humans with credentials as final reviewers; document approvals.

• Do not ship AI-generated medical or legal advice without expert validation and disclaimers.

• Monitor assistants for hallucinations about your brand; correct with clearer bios, schema, and off-site profiles.

Localization and multi-market compliance

• Translate with native experts; avoid literal translations for legal or medical terms.

• Adapt disclaimers to each jurisdiction (GDPR, HIPAA, PSD2, advertising rules).

• Localize schema: addresses, currencies, licenses, and contact channels.

• Align with local professional bodies; link to country-specific guidelines and regulators.

Evidence tiers to standardize quality

• Tier 1: peer-reviewed studies, official regulatory guidance, statutes, licensed data.

• Tier 2: reputable industry bodies, university research, recognized NGOs.

• Tier 3: proprietary data with transparent methodology.

• Tier 4: expert opinion with clear credentials and disclosed limitations.

• Mark each claim with its tier in editorial notes; prioritize Tier 1/2 for YMYL advice.

Reviewer policy examples

• Medical: board-certified reviewer required for diagnosis or treatment content; re-review every six months or after guideline updates.

• Finance: licensed advisor reviews investment or tax advice; note jurisdiction; refresh after policy changes.

• Legal: licensed attorney reviews; include bar number; avoid jurisdictional overreach; add clear disclaimers.

• Lifestyle YMYL (nutrition, parenting safety): credentialed specialist reviews, plus citation of official guidelines.

Topic triage and ownership

• Define topic owners for each cluster; only owners can approve major updates.

• Create escalation paths for breaking news or regulatory changes; fast-track reviews and disclaimers.

• Use intake forms for new YMYL requests with fields for sources, author credentials, and risk assessment.

Tools and automation

• CMS workflows that block publish without reviewer and source fields.

• Schema linting in CI to ensure author, reviewer, and date fields exist and match @id values.

• Crawlers that flag missing disclaimers, outdated dates, or broken citations.

• Warehouse + BI to blend Search Console, AI citation logs, and freshness data into one dashboard.

• Consent and privacy scanners to ensure banners and scripts comply with local rules.

AI assistant monitoring prompts

• “Which sites do you trust for [YMYL topic]?” — compare cited domains to your targets.

• “Who reviewed this advice?” — verify assistants surface your reviewers and credentials.

• “When was this information last updated?” — confirm recency is visible to models.

• “Is this safe to follow?” — catch missing disclaimers or ambiguous instructions.

• Log outputs monthly and tie fixes to prompt trends.

Common mistakes to avoid

• Mixing AI-generated text with expert bios without review, creating mismatched claims.

• Using generic disclaimers that do not fit the market or topic risk level.

• Letting plugins create duplicate Person or Organization schema, confusing assistants.

• Ignoring accessibility on consent banners, causing blocked content and poor experience.

• Failing to document changes; without logs you cannot prove governance in audits.

Team roles and accountability

• SEO lead: defines YMYL scope, owns scorecard, and tracks AI citations and SERP performance.

• Editorial lead: enforces templates, evidence tiers, and reviewer assignments.

• Legal/compliance: validates disclaimers, licenses, and jurisdiction coverage; reviews AI use policies.

• Engineering: maintains schema, performance, and reliability for YMYL templates.

• PR/comms: supports off-site reputation with authoritative mentions and correct author bios.

Sample disclaimer patterns

• Legal: “General information, not legal counsel. Consult an attorney licensed in your state. Reviewed by [Reviewer], Esq., Bar #[number].”

• Parenting/safety: “Based on official guidance as of [date]; check local regulations. Reviewed by [Reviewer], [credential].”

• Place disclaimers near the intro and CTAs, and reference them in schema with description and isBasedOn.

Stakeholder communication

• Publish a public Editorial Policy and Review Board page that lists reviewers and update cadences.

• Send monthly governance summaries to legal and leadership: pages reviewed, claims updated, and pending risks.

• Maintain a correction process: intake form, SLA, on-page correction logs, and schema updates to reflect revisions.
