E-E-A-T and Google Algorithm Updates: How Ranking Changes Impact Your Content

When Google releases algorithm updates, many website owners notice significant changes in their search rankings. Some sites see traffic increase, while others experience declines. Understanding how these updates connect to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) principles can help you prepare for future changes and understand what's happening when your rankings shift.

This comprehensive guide explains how E-E-A-T has evolved alongside Google's algorithm updates, which updates most heavily emphasize E-E-A-T signals, and how to align your content strategy with the direction Google is heading.

The Evolution of E-E-A-T in Google's Algorithm

E-E-A-T has been central to Google's content quality evaluation since 2014, when the Search Quality Rater Guidelines first introduced E-A-T. However, the relationship between E-E-A-T and actual algorithm updates has evolved significantly over the years.

E-E-A-T: Framework vs. Ranking Factor

It's important to understand that E-E-A-T is not a direct ranking factor in Google's algorithm. As Google states:

"E-E-A-T is a framework that helps guide how we evaluate content quality. It's used by our Search Quality Raters to assess results, but it's not a direct ranking signal in our algorithm."

However, the factors that demonstrate strong E-E-A-T – author credentials, backlinks from authoritative sources, comprehensive content, original experiences – are the same signals that Google's algorithms measure when ranking content. This means that while Google doesn't have an "E-E-A-T score" in its algorithm, websites with strong E-E-A-T signals tend to perform better in search results.

How Algorithm Updates Amplify E-E-A-T

Google's algorithm updates often refine how existing ranking factors are weighted and evaluated. When updates emphasize content quality (which most modern updates do), they're essentially putting more weight on the same signals that indicate strong E-E-A-T.

Major Algorithm Updates and Their E-E-A-T Connection

Understanding how major updates relate to E-E-A-T helps you understand what Google is prioritizing and why certain sites gain or lose visibility.

The Medic Update (August 2018)

What happened: This Core Update, dubbed the "Medic Update," significantly impacted health and wellness websites, with many seeing substantial ranking changes.

E-E-A-T connection: The Medic Update highlighted the importance of expertise and authority, especially for YMYL (Your Money or Your Life) content. Websites lacking strong credentials, author information, and medical expertise signals saw declines, while sites with clear medical credentials and authoritative sources improved.

Lessons for content creators:

• YMYL content requires especially strong expertise signals
• Author credentials matter significantly for health content
• Sites without clear expertise indicators struggled
• Medical and health content must demonstrate formal qualifications

What this means today: The Medic Update established that expertise and authoritativeness matter more for sensitive topics. This principle continues to guide how Google evaluates YMYL content.

The Product Reviews Update (April 2021, December 2021, March 2022, July 2022, February 2023, April 2023)

What happened: Multiple Product Reviews Updates refined how Google evaluates product review content, rewarding reviews that demonstrate genuine experience and expertise.

E-E-A-T connection: These updates heavily emphasized the "Experience" component (which became official in December 2022):

April 2021 focus:

• Reviews with original photos and videos from actual product use
• Detailed testing methodology documentation
• Specific product details only someone who used it would know
• Comparison with similar products

February 2023 focus:

• Reviews from "real" people, not just sites that aggregate reviews
• Evidence of firsthand product testing and evaluation
• Original images and videos of products in use
• Detailed insights about product performance

Lessons for content creators:

• Product reviews must demonstrate actual product experience
• Original photos and videos are critical experience signals
• Detailed testing processes show expertise
• Generic, templated reviews lose visibility

What this means today: Product review content must clearly demonstrate first-hand experience through original visuals, detailed testing, and specific insights from actual product use.

The Helpful Content Update (August 2022, December 2022, September 2023, March 2024)

What happened: The Helpful Content Update introduced a site-wide signal that evaluates whether content was created primarily for search engines or to genuinely help people.

E-E-A-T connection: Helpful Content aligns closely with E-E-A-T principles:

Key signals evaluated:

• Does content demonstrate first-hand experience?
• Is content written by someone with real expertise?
• Does the site establish authority in its field?
• Is content trustworthy and accurate?

September 2023 refinement:

• Enhanced focus on experience signals (matching the E-E-A-T framework)
• Better detection of content written without first-hand knowledge
• Improved evaluation of content helpfulness

March 2024 update:

• Further refined to reduce unhelpful content in search results
• Enhanced understanding of what makes content genuinely helpful
• Better recognition of authentic expertise and experience

Lessons for content creators:

• Content created primarily for rankings struggles
• Demonstrating first-hand experience is increasingly important
• Sites with strong E-E-A-T across all content perform better
• Content quality and helpfulness matter more than keyword optimization

What this means today: The Helpful Content Update system evaluates your entire site, not just individual pages. Maintaining strong E-E-A-T signals across all content is essential.

Core Updates (Multiple dates: March 2019, May 2020, December 2020, June 2021, July 2021, November 2021, May 2022, September 2022, March 2023, August 2023, October 2023, March 2024, November 2024)

What happened: Google releases regular Core Updates that broadly refine how the algorithm evaluates content quality and relevance.

E-E-A-T connection: While each Core Update has unique characteristics, they consistently refine how Google measures:

• Content quality and depth (Expertise signals)
• Website authority and recognition (Authoritativeness signals)
• Trust and reliability (Trustworthiness signals)
• First-hand knowledge (Experience signals, especially post-2022)

Common patterns in Core Updates:

• Sites with comprehensive, expert content often gain visibility
• Websites lacking author information see declines
• Content demonstrating real experience performs better
• YMYL sites without strong credentials struggle

Lessons for content creators:

• Core Updates reward sites that have systematically built E-E-A-T
• One-time improvements aren't enough – E-E-A-T requires ongoing commitment
• Sites with balanced E-E-A-T across all dimensions tend to be more resilient
• Declines often indicate gaps in one or more E-E-A-T components

What this means today: Regular Core Updates mean E-E-A-T isn't a "set it and forget it" effort. Continuous improvement and maintenance are necessary.
