How Google's 2025 updates are transforming online search

In 2025, Google began a major transformation of its search engine, redefining the rules of SEO and the expectations of content creators. With increased integration of artificial intelligence, significant algorithm updates, and a stronger focus on content quality, web professionals must adapt to stay visible. Here’s an overview of the key changes shaping Google Search in 2025.

March 2025 core update: A content evaluation overhaul

On March 13, 2025, Google rolled out its first major update of the year, the "March 2025 Core Update," which concluded on March 27. Unlike previous updates that targeted specific aspects such as spam or product reviews, this one represents a systemic re-evaluation of how Google assesses and ranks web content.

Sectors like healthcare, education, and media experienced major ranking fluctuations. This update highlights the importance of E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness), now essential to appear at the top of the results.

Sites that demonstrate deep expertise, recognized authority, and strong trustworthiness are now prioritized. It is therefore crucial to produce content that aligns with search intent, is useful, original, and logically structured. Google is refining its ability to interpret the intent behind each query. From now on, the algorithm rewards in-depth, relevant analysis and moves away from overly general information.

Google penalizes abusive use of AI

Google recently clarified its stance on AI-generated content. While AI can assist in content creation, excessive or unsupervised use can lead to penalties.

Pages primarily made up of automatically generated, rephrased, or copied content with little added value are particularly at risk. The search engine also tracks content authored by fictitious "authors," lacking transparency or presenting contradictions.

However, Google does not demonize AI. The company sees AI as a tool that can contribute to a better web, but given  that the generated content is enriched, verified, and user-oriented. To stay competitive in Google Search 2025, authenticity, expertise, and content coherence must be guaranteed.

Toward a unified search experience

In a move toward standardization, Google is gradually redirecting its local domains to google.com. Results will still be localized based on user location, but this unification aims to provide a smoother experience, especially for mobile users and connected devices.

This strategy also supports the rollout of new AI-powered features, which require globally unified infrastructures for effective deployment.

AI and AI mode: A new way to search

Among the major revolutions in Google search 2025, the introduction of AI mode is perhaps the most striking. Google is experimenting with this new version of its engine, where traditional results are replaced by AI-generated summaries, accompanied by links to reliable sources.

Accessible through the Google one AI premium subscription, this feature aims to respond quickly and effectively to complex queries. AI answers are powered by the Gemini model, also integrated into Android and Google services, enabling more natural and contextual interaction.

This trend confirms Google's move toward a conversational and intelligent search experience.

To meet Google’s new expectations, here are some SEO best practices to implement right away:

1. Focus on content quality

Your content must be useful, unique, structured, and clearly address the user’s intent. Forget keyword stuffing and start prioritising user experience.

2. Strengthen your E-E-A-T signals

Showcase your authors, cite credible sources, and provide proof of authority in your field.

3. Supervise the use of AI

Use AI tools to speed up content creation, but always include human review and enrichment. Be transparent about your process.

Track Google’s testing of AI Mode and anticipate its impact on organic search by adapting your content formats and strategy accordingly.

In conclusion
