Identify YMYL content on your site

SkillCommerce & finance

ymyl-detection is an agent skill for identifying and auditing YMYL (Your Money or Your Life) content on a website. It checks pages covering health, finance, legal, safety, and similar topics against Google's Quality Rater Guidelines, flagging missing author credentials, citations, expert review, and update dates that can lower quality ratings.

Available today. Use it from your connected AI after setup.

Have a site with content in health, medicine, finance, law, safety, news, or similar fields.

Then ask your AI: use the Identify YMYL content on your site skill

What your AI can do with it

  • Identify pages covering medical, financial, legal, safety, or civic topics
  • Check YMYL pages for author names, credentials, and qualification in the topic area
  • Verify claims are supported by cited, authoritative sources and expert review
  • Flag missing trust signals such as 'reviewed by' notes and last-reviewed dates
  • Review metadata, rendered HTML, structured data, and response headers for violations
  • Explain YMYL standards and how Quality Raters assess E-E-A-T

Getting started

  1. Have a site with content in health, medicine, finance, law, safety, news, or similar fields.
  2. Add the ymyl-detection skill to the agent's available skills.
  3. Ask the agent to audit content quality for YMYL categories or investigate why high-quality-seeming content underperforms.
  4. Review the flagged pages and apply fixes such as author bylines, citations, and review notes.

What this skill tells your AI

The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/ymyl-detection/SKILL.md and read by ahel’s review.

Google's Quality Rater Guidelines require YMYL pages to meet higher E-E-A-T standards than general content — a YMYL page without visible expertise and trust signals will be rated low quality regardless of technical SEO.

Quick Reference

  • YMYL pages cover topics where inaccurate information could harm a user's health, safety, finances, or wellbeing
  • Google applies its highest quality standards to YMYL content — E-E-A-T must be demonstrably high
  • YMYL pages must display author credentials, cite authoritative sources, and be reviewed by qualified experts
  • Missing trust signals on YMYL pages can cause poor manual quality ratings that suppress rankings

Check

Identify pages covering medical, financial, legal, safety, or civic topics. For each YMYL page, check: Does it display author name and credentials? Is the author qualified in the topic area? Are claims supported by cited, authoritative sources? Was the content reviewed by a relevant expert? When was it last updated?

Fix

Add author bylines with credentials to YMYL pages. Link author names to bio pages that describe their qualifications. Add citations to primary sources (peer-reviewed research, government data, official guidelines). Add a 'reviewed by' note with the reviewer's credentials. Update outdated YMYL content with a visible last-reviewed date.

Explain

Explain what YMYL content is, why Google applies stricter quality standards to it, how Quality Raters assess E-E-A-T on YMYL pages, and what steps content teams should take to meet those standards.

Code Review

Review metadata generation, rendered HTML, structured data, and response headers related to Identify YMYL content on your site. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
