SEO Challenges 2025: how to turn the hurdles into opportunities for 2026

2025 made it clear that SEO is undergoing a profound transformation: AI Overviews reshaped the SERPs, core updates caused unprecedented volatility and experience metrics became decisive. We review the challenges and the trends that will take hold next year.

The impact of AI Overviews

In 2025, AI Overviews stopped being a test and became a reality across multiple markets, taking clicks away from traditional results. Media and software companies have already reported CTR drops on informational keywords.

The immediate challenge is designing content that AI cannot replicate: answering key questions with clear, structured sections, providing your own data and real cases, and enriching the material with charts, tables or studies that deliver distinctive value against automated summaries.

Constant algorithm changes and core updates

Between March and July 2025, Google rolled out multiple updates that affected sectors such as health, ecommerce and media. To cushion the impact, it is essential to set up weekly KPI monitoring routines, document lessons learned after each update, and diversify traffic sources so as not to rely solely on Google.

Core Web Vitals and experience metrics (INP, CLS, LCP)

Replacing FID with INP raised the bar for interactivity, and many sites have not yet managed to adapt. It is essential to reduce the latency of heavy scripts, optimize visual stability to avoid unexpected shifts, and prioritize the fast loading of critical elements. Improving these metrics has a direct impact on user satisfaction and conversion.

The rise of UGC and quality moderation

User-generated content —reviews, comments, forums— is gaining weight as a trust signal and a source of long-tail keywords. The challenge will be striking a balance: encouraging useful, contextual reviews, implementing hybrid moderation (AI + human review), and highlighting the most relevant testimonials on key pages.

Privacy and regulations (cookies, tracking)

The gradual phasing out of third-party cookies is already impacting measurement. 27% of users block cookies, making conversion tracking harder. Companies must bet on first-party data (newsletters, CRM forms) and implement AI-based attribution models. Communicating clearly how data is used strengthens user trust.

Content creation with reinforced EEAT

In 2025 Google doubled down on EEAT, penalizing sites without clear authorship or external references. As Juan Ignacio Retta, director of Seotronix, explains, «today EEAT is not just about showing credentials, but about building trust sustained over time».

Publishing content signed by specialists, citing trusted external studies, and maintaining complete, up-to-date author profiles are no longer differentiators: they are basic requirements to compete.

Growing competition from marketplaces and aggregators

Amazon, Mercado Libre and other marketplaces expanded their presence in the SERPs, especially in transactional searches. An effective strategy is to target underserved long-tail niches, offer more detailed comparisons and guides, and strengthen branding with solid storytelling: standing out in spaces they do not cover with the same depth.

Local SEO with hyper-personalized searches

Terms like «near me» now include time context, reviews and real-time availability. It is key to keep the Google Business Profile optimized in detail, create specific content for neighborhoods or local events, and encourage geolocated reviews with recent photos.

The role of internal linking and information architecture

Sites with clear structures and well-defined hierarchies weathered the fluctuations of core updates better. It is advisable to reinforce the building of topical silos, use descriptive and natural anchor texts, and frequently audit broken links or redirects.

Automation and AI in SEO workflows

AI automation sped up reporting, clustering and draft generation, but it also led to penalties for those who abused automated content. The key is balance: use AI for repetitive or technical tasks, manually review everything before publishing, and train teams in responsible use.

The road to 2026

The takeaway from 2025 confirms that SEO no longer depends on isolated actions, but on the ability to adapt to constant change. Every challenge is also an opportunity: improving the user experience, reinforcing authority, differentiating the value proposition, and turning SEO into a sustainable engine of growth.
