September 2026 marks a regulatory turning point for the European web. Several texts adopted in recent years, from the Digital Services Act to the AI Act, are moving from a theoretical framework to concrete actions against major platforms and artificial intelligence providers. Digital trends are no longer limited to new marketing tools or SEO tricks: they are now also reflected in the records of the European Commission.
ChatGPT classified as a search engine by the DSA: what this changes for the web
The European Commission has designated ChatGPT as a very large search engine under the Digital Services Act, alongside Reddit and Roblox, classified as very large online platforms. The decision, made public on September 4, 2026, requires these services to implement enhanced obligations for assessing and mitigating systemic risks.
Compliance is expected within four months of notification. In practical terms, a chatbot that generates responses from web sources is subject to the same transparency requirements as Google or Bing.
For digital professionals, this classification raises a direct question: how will the content referenced by a chatbot be audited? The transparency obligations of the DSA imply that ChatGPT will have to account for how it selects and presents information. Website publishers following the news on Le Petit Webmaster are measuring the potential impact on organic visibility.
In contrast, the designation of Reddit as a very large online platform follows a different logic. Reddit aggregates content generated by its users, not by a language model. The two cases illustrate that the DSA does not treat all web actors the same way, even when they influence online search.
AI Act and control of generative AI models: the operational phase
The European AI office has sent its first formal requests for information to general-purpose artificial intelligence model providers at the end of August and early September 2026. This step marks the beginning of the effective use of the control powers provided by the AI Act.
The requests focus on the safety and transparency of the models. For companies integrating generative AI into their marketing tools, customer service, or content production, the implications are concrete.
- Model providers will need to document the training data used, which could change the terms of use for consumer tools
- The transparency obligations imply stricter labeling of AI-generated content, with direct consequences for SEO content strategies
- Companies using these models are not directly targeted by the current requests, but depend on their providers’ compliance
The available data does not yet reveal which providers have received these requests or what the timeline for responses will be. The European regulatory framework progresses in stages, and this inquiry phase could last several months before producing public decisions.
Google Search and SEO in September 2026: spam update and new filters
Google has launched the September 2026 Spam Update, its fourth anti-spam update of the year, just over a month after the previous one. The pace is clearly accelerating. For SEO professionals, this rhythm means that the leeway for borderline techniques is continuously shrinking.
Another new feature on the SEO side: the Search Console now includes a filter dedicated to traffic from image searches. Searches initiated from a smartphone camera or a screenshot are now distinguished from traditional text queries. This filter provides webmasters with a more detailed view of their traffic sources at a time when visual search is gaining ground on mobile.
These two developments, taken together, depict a Google that tightens control over the quality of results while refining the measurement tools available to publishers. The open question remains the actual impact of the spam update: feedback often diverges on this point between affected sites and those that benefit.
Cyber Resilience Act and security of digital products: new obligations
The Cyber Resilience Act now imposes accelerated reporting obligations for products containing digital elements. In practical terms, manufacturers and software publishers will need to notify actively exploited vulnerabilities within tight deadlines.
For digital enthusiasts, this regulation touches on an often-overlooked aspect of web news. CMSs, plugins, WordPress themes, browser extensions: all these elements potentially fall within the scope of the text.
Companies developing online tools for their clients, or managing sites with numerous technical dependencies, will need to adapt their security monitoring processes. The text is not limited to connected objects or computer hardware; it also covers software components distributed in the European market.
Web trends 2026: beyond digital marketing
Competitors on this topic primarily focus on marketing trends: generative AI for content creation, social commerce, micro-influencers, personalization. These angles remain relevant, but they obscure a deeper movement.
The year 2026 is characterized by a convergence between European regulation and daily web practices. An SEO writer using a language model is now working with a tool subject to the DSA. A developer publishing a plugin must anticipate the obligations of the Cyber Resilience Act. A marketing manager collecting first-party data operates within a framework where the CNIL and its European counterparts have enhanced powers.
The digital trends in 2026 are not just a list of technologies to adopt. They are reflected in legal texts, classification decisions, and the first information requests sent to AI giants. Web enthusiasts who only follow product innovations are missing a structural transformation of the framework in which these products exist.
