The March 2025 Core Algorithm Update, the first core update of this year-is oriented toward promoting high-quality, E-E-A-T friendly content. 

In addition, user experience was further emphasized by rewarding sites according to better core web vitals such as faster load times and mobile-friendliness.

Although this is just a regular core update by Google following the December 2024 Core Update, what we need to focus on in this update is content creator visibility.

5 Major Changes in March 2025 Google Core Update

Visibility of Content Creators

Google has enhanced several factors this year for content creators, including:

Author Transparency: Clear author attribution is now more important, as content from identifiable, credible creators with verified expertise is more likely to rank higher.

E-E-A-T Signals: Creators who share real-life experiences, case studies, or expert insights will gain better visibility.

Increased Credit for Author Profiles: Enhanced author bio, as well as links to social profiles and professional credentials are used to boost content rankings.

User Engagement Signals: Google has increasingly started to weigh engagement metrics like time on page, scroll depth, and bounce rates when deciding which content to favor for real-user engagement.

User Intent Matching

The search engine now gives better results for long-tail and conversational queries, focusing on content that directly answers specific questions. 

With more advanced Natural Language Processing models, Google can recognize synonyms and related terms, making it less dependent on exact-match keywords.

This is key since most searches are informational (70%), while commercial (22%), navigational (7%), and transactional (1%) searches make up the rest.(SE Ranking)

Increased Focus on Content Authenticity and Trustworthiness

Google’s commitment to promoting trustworthy content, especially for YMYL (Your Money or Your Life) niches like health, finance, and legal topics, is reflected in its E-E-A-T Guidelines. 

The update strengthens E-E-A-T signals by:

• Boosting content with verified expert authorship
• Prioritizing sources with strong brand authority
• Devaluing AI-generated content lacking human oversight

Algorithmic Penalty for AI-Generated Spam

Google is tightening its stance on low-quality, mass-produced AI content. 

The March update introduces an advanced spam filter to detect and penalize websites over-reliant on AI-generated content without proper human curation.

Spammy AI practices targeted: Thin, repetitive, or nonsensical AI-generated pages.

AI detection algorithms: Google now uses more sophisticated machine learning models to identify and down-rank AI spam.

Core Web Vitals Update: UX Takes Center Stage

According to Ahrefs data, only 33% of websites pass Core Web Vitals, making it clear that many sites still fall short on performance standards. 

To improve user experience, This update introduces new benchmarks for these metrics, making Core Web Vitals even more important for SEO.

Interaction to Next Paint (INP): Measures responsiveness and replaces First Input Delay (FID) as a ranking factor.

Cumulative Layout Shift (CLS): Websites with unstable, shifting content will face penalties.

Page loading speed: Faster, lightweight sites are favored, especially for mobile users.

FAQs

How do the March 2025 updates affect AI-generated content?

Google comes after it, against low-quality mass-produced AI content. It is still possible to use AI content creation, but the content will have to be reviewed by a human, accurate, and valuable if it is to escape penalties.

Will smaller websites struggle to rank after the update?

Personally, I don’t see that happening. Niche authority, quality content, and a solid local SEO strategy can make small websites perform well. It’s relevance and trustworthiness, not size, that Google counts when it comes to ranking.

How can I improve my website’s E-E-A-T signals?

Display author credentials, link to credible sources, include expert reviews, ensure HTTPS protocols secure the website, and provide clear contact information.

What role does UX play in the new algorithm?

Websites with fast load speeds, stable layouts, and smooth interaction features will win rank benefits. Poor UX sites lose visibility.

How do local businesses benefit from the March 2025 update?

With accurate NAP data, good positive reviews from customers, and regionally based content, businesses can find their way to local search results by Google’s bias towards proximity and reputation.
