The March 2026 Core Update has shaken up the SERP landscape in just four rollout weeks. Industry trackers reported the biggest swings in months - and those who reflexively rewrote texts and touched structures in the first few days are now likely to regret it. Cause and effect can only be separated if you first measure and then act.

Anyone who still focuses their content mainly on keyword density has missed the last two years. AI agents and Search Generative Experience have changed how content is evaluated, found and cited. Content relevance means something different today than it did in 2022.

KI browser: Atlas, Comet - the changing face of browsing?

Many users already work with a dual setup: The browser runs in one tab with dozens of open pages, while an AI tool such as ChatGPT or Perplexity, which is supposed to explain or summarize content, runs in the other tab. This is exactly where AI browsers come in and integrate this assistance directly into the browser. The pages continue to load as normal, but an integrated AI „reads“ in parallel, helps to classify, summarize and compare information and - depending on the solution - can also support simple steps on the web. The spectrum ranges from classic browsers with an additional AI function to AI-first browsers such as Atlas or Comet, which were designed from the outset so that the AI level forms the core of use.

Structured data in SEO and AI searches

Structured data in JSON-LD format - sample code for SEO and machine-readable information in modern AI browsers.

Structured data is no longer an add-on, but a central element in digital marketing. It helps machines to interpret content correctly and link it together. AI search systems can use structured data to better categorize content or check which information is reliable and to which entity it belongs. This increases the chance of content appearing in AI answers. There is no guarantee of this - quality, trust and technical stability remain crucial.

Google AI Mode is noticeably changing the search: away from individual questions and towards guided clarification with comprehensible sources. Anyone publishing content should structure answers clearly and offer internal paths to more in-depth topics. Searchers will find their way around more quickly - and retain control over the information.

Google is redesigning search. The main difference between AI Overviews and the classic SERPs lies in the way an answer is presented: AI Overviews provide a direct summary created by the AI. The classic search, on the other hand, displays a list of links to your own search. This shortens and fundamentally changes the path from the question to the answer - the user journey.

Puzzling drop in impressions in the Google Search Console

Many website operators observed a strange development in mid-September 2025: In the Google Search Console (GSC), impressions suddenly plummet, while the average position increases and the number of clicks remains stable. This discrepancy is unsettling, as fewer impressions could be an indication of poorer visibility - but organic traffic usually remains unchanged. How can this be explained?

LLM SEO is about designing content in such a way that large language models (LLMs) such as ChatGPT or Google AI not only understand it, but also use it as a primary source for their answers. Put simply, your content becomes the basis for AI-generated recommendations.

SEO for ChatGPT is about preparing web content in such a way that AI systems like ChatGPT use it as a trustworthy source of information. Instead of just optimizing for keywords for Google searches as before, the focus is on providing clear, precise and clearly structured answers. The aim is for these to appear directly in the AI's dialogs.
