Key Takeaway
In 2025, SEO is being redefined by Google’s spam update, the removal of the &num=100 parameter, AI-driven search with Generative Engine Optimization (GEO), the rise of zero-click results, conversational keywords, Core Web Vitals 2.0, and the growing importance of E-E-A-T. Success now depends on combining technical excellence with authentic, experience-driven content and strong brand visibility.
SEO in 2025: A Rapidly Transforming Landscape
The SEO landscape is evolving fast. Marketing agencies and brands that rely on online visibility need to adapt quickly. Beyond regular algorithm tweaks, we now see structural shifts that redefine how websites are indexed and how users interact with search results.
Google Spam Update: A Month of Turbulence
Between August and September 2025, Google rolled out a spam update that lasted for 27 days. The update aimed to reduce low-quality content and aggressive optimization practices.
Impact on Agencies
- Agencies must focus on authentic, user-first content.
- Manipulative SEO tactics face higher risk than ever.
The Removal of &num=100: End of a Long-Time Practice
Google removed the &num=100 parameter, which allowed users to display 100 results per page.
Consequence for SEO Professionals
- Rank tracking tools and impression reporting were disrupted.
- Workflows for audits and performance monitoring must be adapted.
SEO + AI: A Unified Ecosystem
SEO can no longer be separated from AI. Website structure now feeds AI models that influence both analysis and distribution of content.
What GEO Means
- Content must be optimized for classic SERPs and AI responses.
- Proper structure is key to being cited by AI.
- Agencies must think in terms of multi-visibility: SERPs, AI Overviews, and conversational search.
Zero-Click Search: Direct Traffic Shrinks, Brand Pressure Rises
Zero-click searches are increasing as snippets, AI Overviews, and direct answers resolve user queries within the SERP.
Business Implications
- Content must boost brand recall even without clicks.
- Authority and reputation are essential for visibility.
Conversational Keywords: A Paradigm Shift
Keyword research is shifting toward natural phrasing, long-tail queries, and conversational tone aligned with AI and voice search.
Example
- Traditional search: “Italian restaurant Bucharest”
- Conversational search: “What is the best Italian restaurant in Bucharest for a romantic dinner?”
Core Web Vitals 2.0: User Experience Takes Center Stage
Google expanded its Core Web Vitals. Alongside LCP, CLS, and FID, the new Interaction to Next Paint (INP) measures responsiveness.
Key Takeaway
Site performance is now directly tied to SEO visibility, making technical optimization unavoidable.
E-E-A-T: Experience as the Differentiator
Google’s quality framework has evolved from E-A-T (Expertise, Authoritativeness, Trustworthiness) to E-E-A-T, with Experience added.
Why It Matters
- Content with real-world proof (case studies, expert insights, author credibility) ranks higher.
- Superficial or generic content loses authority and traffic.
Conclusion: SEO is Now a Balance Between Tech and Authenticity
In 2025, SEO success relies on a hybrid approach:
- Technical adaptation: Core Web Vitals, &num=100 removal
- Visibility in AI & GEO: AI Overviews and Generative Engine Optimization
- Content: authentic, conversational, and experience-driven
- Branding: strong enough to stand out even in zero-click searches
Winners will be those who see SEO as part of an integrated ecosystem, where technology and human insight complement one another.
