What is Search Quality Rater Guidelines?
Learn what Search Quality Rater Guidelines means, why it matters for search rankings, and how consistent content publishing keeps your business visible in Google.
Definition
The Search Quality Rater Guidelines are a 170+ page document Google provides to human evaluators who assess search results and websites, serving as the blueprint for how Google defines and measures content quality.
What Are the Search Quality Rater Guidelines?
The Search Quality Rater Guidelines (SQRG) are a comprehensive document published by Google that instructs human evaluators — called “Quality Raters” — on how to assess the quality of search results and individual web pages.
Quality Raters do not directly influence rankings. They cannot move your site up or down in search results. Instead, their ratings help Google validate and refine its algorithms. When thousands of raters consistently rate certain types of pages as low quality, Google’s engineering teams use that feedback to train algorithms that detect similar patterns automatically.
The document is updated regularly. Major updates typically occur annually, with smaller revisions throughout the year. The most significant recent changes include the addition of E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) and expanded guidance on AI-generated content.
Why the Guidelines Matter for SEO
While raters do not control rankings, the guidelines reveal exactly what Google considers high-quality content. Every SEO strategy should align with these principles.
Key insight: Google’s algorithm updates — including Core Updates and the Helpful Content System — are designed to automatically detect the same quality signals that human raters evaluate. Understanding the guidelines helps you create content that satisfies both human raters and algorithmic ranking systems.
The Core Concepts
Page Quality (PQ) Rating
Raters assign every page a Page Quality rating from Lowest to Highest:
| Rating | Description | Typical Characteristics |
|---|---|---|
| Lowest | Harmful, deceptive, or spammy | Malicious content, scams, auto-generated gibberish |
| Low | Poor quality, untrustworthy | Thin content, no E-E-A-T, misleading information |
| Medium | Average quality | Adequate content, moderate E-E-A-T, no major issues |
| High | Above-average quality | Comprehensive content, strong E-E-A-T, original value |
| Highest | Exceptional quality | Definitive resources, recognized expertise, extensive original research |
Needs Met (NM) Rating
Raters also evaluate how well a result satisfies the user’s query:
| Rating | Meaning |
|---|---|
| Fails to Meet | Completely irrelevant or harmful |
| Slightly Meets | Marginally relevant but inadequate |
| Moderately Meets | Somewhat helpful but missing key information |
| Highly Meets | Very helpful, answers the query well |
| Fully Meets | Perfect answer, no need for other results |
E-E-A-T: The Quality Framework
The most important concept in the guidelines is E-E-A-T, which stands for:
Experience
The content creator has first-hand, personal experience with the topic. This is the newest addition to the framework (added in December 2022).
Examples of Experience:
- A product review written by someone who actually used the product
- A travel guide written by someone who visited the destination
- A recipe with photos from the author’s own kitchen
Expertise
The content creator has demonstrable knowledge and skill in the subject area.
Examples of Expertise:
- Medical advice written by a board-certified doctor
- Financial guidance from a certified financial planner
- SEO advice from someone with documented campaign results
Authoritativeness
The content creator and the website are recognized as go-to sources for the topic.
Authority signals:
- Backlinks from other authoritative sites
- Mentions in reputable publications
- Industry awards and recognition
- Social proof (followers, engagement, citations)
Trustworthiness
The page and website are accurate, honest, safe, and reliable.
Trust signals:
- Accurate, factual information with cited sources
- Secure website (HTTPS)
- Clear contact information and ownership
- Transparent about affiliations and sponsored content
- Positive reputation and reviews
YMYL: Your Money Your Life
The guidelines place special emphasis on YMYL topics — content that can significantly impact a person’s health, financial stability, safety, or well-being.
YMYL categories:
- Health and medical information
- Financial advice and investments
- Legal information and advice
- News about major events
- Information about major civic decisions (voting, government)
- Safety information (car maintenance, emergency preparedness)
YMYL content requires the highest E-E-A-T. A health article written by an anonymous author with no credentials will receive a Low or Lowest rating, regardless of how well-written it is.
Key SEO Takeaways from the Guidelines
1. Content Should Have a Clear Purpose
Every page should exist to help users. Pages created primarily to rank in search engines — with no genuine user value — receive Low or Lowest ratings.
2. Authorship Matters
Google wants to know who created the content and why they are qualified. Include:
- Author names and bios
- Author credentials and expertise
- Links to author profiles or professional pages
- Publication dates and update dates
3. Supplementary Content Should Enhance, Not Distract
Ads, pop-ups, and interstitials are acceptable in moderation. But when they dominate the page or interfere with the main content, they hurt quality ratings.
4. Reputation Research Is Part of Rating
Raters are instructed to search for reputation information about websites and authors. A site with numerous negative reviews, scam reports, or complaints will receive lower ratings regardless of its on-page content.
5. AI-Generated Content Has Specific Guidelines
The December 2023 update added explicit guidance on AI-generated content:
- AI content is not inherently bad
- AI content must be accurate, helpful, and reviewed by humans
- AI content on YMYL topics requires higher scrutiny
- Content created primarily to game search rankings is considered spam
How to Apply the Guidelines to Your Content
Before publishing, ask these questions:
- Would a user feel satisfied after reading this page, or would they need to search elsewhere?
- Is the author clearly identified with relevant credentials?
- Are claims supported by evidence, sources, or data?
- Does the content demonstrate first-hand experience or original research?
- Is the page design clean and focused on the content?
- Would you trust this page with your money, health, or safety?
If you answer “no” to any question, improve the content before publishing.
