Understanding E-E-A-T and YMYL: Essential Google Ranking Factors

Have you heard of E-E-A-T and YMYL? These critical factors significantly influence how Google ranks your content in search results.

Consider this: health blogs need genuine expertise to rank well, while financial content must come from trustworthy sources to appear in top results.

This guide breaks down these important concepts in simple terms, showing you exactly what they mean and how to improve your website's rankings with practical, actionable steps.

What is E-E-A-T?

E-E-A-T represents four criteria Google uses to evaluate content trustworthiness. It's essentially a framework for assessing "who created this content" and "how reliable is the information."

  • E = Experience
    First-hand knowledge from personal engagement. For example, "My observations after staying at this hotel for 3 nights" or "What I discovered after using this camera for 2 years."
  • E = Expertise
    Specialized knowledge in a particular field. For example, dietary advice from a nutritionist or programming explanations from a software developer.
  • A = Authoritativeness
    Recognition and respect within an industry. For example, being featured in reputable publications or receiving endorsements from established organizations.
  • T = Trustworthiness
    Content reliability and transparency. For example, clearly citing sources, referencing current data, and providing comprehensive background information.

Google has officially emphasized that "Trust" is particularly important.
This is good news! Even without formal expertise, you can still rank well by documenting genuine experiences, such as "results from my actual testing."

For instance, a beauty blog gains trustworthiness by showing evidence: a receipt photo of the purchased product, before and after skin condition images, and detailed observations after one week of use.

What is YMYL?

Your Money, Your Life refers to information that could significantly impact a person's financial stability, health, safety, or well-being.

For example, inaccurate claims like "this investment guarantees profits" or "this remedy will cure your condition" could have serious consequences for readers who act on this information.

YMYL specifically covers topics where misinformation could harm people's lives or finances, including investment advice, health information, medical guidance, legal consultation, and parenting recommendations.

Google applies particularly rigorous standards to these topics because of their potential real-world impact. For medical content, articles written by healthcare professionals typically rank higher than personal anecdotes from non-experts.

The connection is straightforward: the more critical the information, the more important it is that it comes from a reliable source.

For instance, a minor error in a list of "best ramen restaurants" won't cause significant harm, but incorrect information about medication dosage could be dangerous.

This is why Google applies stricter standards to YMYL topics, where the question of "how reliable is this information?" heavily influences search rankings. Sites demonstrating strong E-E-A-T qualities naturally rank higher in these sensitive areas.

Consider this example: In content about "dietary management for diabetes," articles written by qualified nutritionists consistently outrank similar content created by non-specialists, even when covering the same information.

Industry Examples: When E-E-A-T is Crucial in YMYL

Medical/Health

Medical information directly impacts human wellbeing, requiring exceptional reliability. An article on "dietary therapy for diabetes" gains significant credibility when it includes expert validation, such as "reviewed by Dr. △△, Endocrinologist at ○○ University Hospital."

Currency of information is equally important—statements like "This article reflects the latest clinical guidelines as of October 2023" are essential because outdated medical advice can pose serious risks.

Finance/Legal

Inaccurate financial or legal information can directly affect your assets and rights. Content about "mortgage tax deductions" becomes more trustworthy when presented by a qualified professional, such as "explained by ◇◇, Certified Tax Accountant."

Highlighting recent regulatory changes is particularly crucial—for example, "The deduction rate was adjusted in the 2023 tax reform." Using outdated information for tax filing could result in financial losses or even penalties.

News

For news content, source transparency is paramount. When reporting that "The Prime Minister announced a new policy," credibility increases substantially by including a direct link to the official source: "View the complete announcement on the Prime Minister's Office website."

News outlets that publish clear editorial policies and correction procedures demonstrate valuable transparency. Readers gain confidence from specific statements like "We verify all facts through at least two independent sources before publication."

Science/Research

Scientific claims require robust evidence. A statement that "This ingredient promotes weight loss" becomes much more convincing when supported by specific research: "A □□ University study documented an average weight reduction of ○ kg across 100 participants over 8 weeks (link to published research)."

Detailed information about methodology, sample size, and measurement techniques allows readers to evaluate reliability. The difference between "tested on 3 individuals" and "verified across 1,000 participants" significantly affects credibility.

Parenting/Housing

Parenting advice and housing decisions impact crucial aspects of daily life. Content addressing "how to soothe a crying infant at night" carries more weight when it comes from demonstrated experience: "This technique has been successfully implemented by the author, a childcare professional with 15 years of experience working with over 100 infants."

Similarly, articles about "earthquake-proofing your home" benefit from visual documentation showing "before, during, and after" stages of implementation. Precise instructions like "Install this bracket at a 45-degree angle" provide actionable value for readers attempting the work themselves.

3 Steps Individual Bloggers Can Take Today

1. Document Your Experience with Evidence

When writing about using a product like "I used this shampoo for 3 months," include before and after photos of your hair to demonstrate real results.

If discussing weight loss success, add visual evidence such as scale readings or body transformation photos to make your content more convincing and trustworthy.

2. Strengthen Your Profile

For specialized content like a cooking blog, establish credibility by sharing relevant qualifications: "I worked in restaurants for 5 years" or "I hold a professional cooking license (調理師免許)."

Including a personal photo and links to your social media profiles helps readers connect with you as a real person behind the content, building trust.

3. Reference Authoritative Sources

When making claims about ingredients or products, cite reputable sources: "According to the Ministry of Health, Labour and Welfare..." rather than stating facts without attribution.

Provide direct links to official sources (like "See the Consumer Affairs Agency data here") so readers can verify information themselves, enhancing your content's credibility.

Summary

E-E-A-T represents Google's framework for evaluating content trustworthiness. It's logical that health information from a medical professional will rank higher than similar content from someone without credentials.

Particularly in YMYL fields like health and finance, vague statements like "I think this works" carry little weight. Instead, specific claims backed by data are valued: "After following this health protocol for 30 days, my blood pressure decreased by 10 points (with measurement data included)."

Begin by sharing authentic experiences supported by visual evidence and concrete metrics. Regularly update your content and, when possible, have it reviewed by subject matter experts.

Even small blogs can improve their search rankings when readers find genuine value in the content. For example, a "bread making for beginners" article might outperform content from major websites if it includes comprehensive step-by-step photos and addresses common mistakes that beginners make.
