Google Core Algorithm Update 2025: Nothing works without user signals

What is the Google June 2025 Core Update all about?

Google has rolled out the update in several phases and has now completed it. As with all core updates, there are no precise details on every change, but some key trends are clearly identifiable:

• Ranking changes: Websites with high-quality, relevant content are benefiting, while less valuable content may lose visibility.
• Focus on user experience: Fast loading times, mobile optimization, and intuitive navigation are being weighted more heavily.
• Content with added value and expertise: Content created by experts that offers genuine utility is particularly relevant.
• Keeping an eye on older content: Pages that are outdated or not updated regularly may lose visibility – a signal to review your content and bring it up to date.

The core message remains: Google rewards websites that offer users clear added value and provide an excellent user experience.

User signals can not only be observed but also specifically improved using A/B testing. Yet, this is rarely done. In our analysis of 2,496 of the largest German online shops, 76 percent operate without a testing tool. In the same period, median organic visibility fell by 16.7 percent, the first decline after three years of growth. If you don't measure your user signals, you won't notice if an update has hit you, nor will you be able to take countermeasures.

What should you do now?

After a core update, proactive action is crucial:

• Review and optimize content: Ensure that your text is well-researched, well-structured, and up to date. Content should demonstrate Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T).
• Improve user experience: Optimize loading times, mobile responsiveness, and intuitive navigation. Tools like PageSpeed Insights or Lighthouse can help with this.
• Update content regularly: Even older pages can benefit from updates if they are brought up to date.
• Analyze user signals: Data such as time on page, bounce rate, or scroll depth helps identify which content truly resonates with users.

By taking these steps, you ensure that Google continues to view your site as relevant and trustworthy.

What do YMYL site operators need to keep in mind?

Websites with Your Money, Your Life (YMYL)content—such as topics related to health, finance, or legal matters—are under particularly close scrutiny:

• Trustworthiness: SSL, transparent legal notices, contact information, and reliable support are mandatory.
• Expertise: Content should be created or reviewed by qualified professionals.
• Regular updates: Especially with sensitive topics, information must be current to convince both Google and users.

Meeting these requirements strengthens E-E-A-T and leads to long-term benefits like stable rankings and satisfied users.

Conclusion

The June 2025 Google Core Update makes it clear once again: Without strong user signals, high-quality content, and an excellent user experience, SEO is no longer possible today.

The combination of technical optimization, continuous content maintenance, and E-E-A-T-compliant content is crucial for competing for top positions in search results.

If you make your users happy, you also make Google happy—securing long-term visibility, trust, and revenue.
