The European Commission has classified ChatGPT as a Very Large Online Search Engine for the first time. Its integrated web search and at least 45 million monthly users in the European Union (EU) triggered the designation. This matters if you use ChatGPT for research or product searches, and if you want your own content to appear in answers generated by Artificial Intelligence (AI).
What changes under the EU designation?
ChatGPT remains a chatbot, but its web-search function means regulators will also treat it as a search engine. Under the Digital Services Act (DSA), a service becomes “Very Large” when it reaches at least 45 million average monthly users in the EU. The European Commission’s classification therefore brings additional oversight and transparency duties for OpenAI.
According to the reports, OpenAI has until the end of December 2026 to meet the requirements. They include assessments of systemic risks, meaning potential harms that extend beyond one individual user. The issues named in the coverage include illegal content, risks to minors, effects on elections and, according to The Verge, risks involving users’ mental health.
Other requirements include transparency reports every six months, a public advertising archive, procedures for reporting and appealing illegal-content decisions, and a crisis-response mechanism. Approved researchers are also supposed to receive access to certain data so they can examine systemic risks. Legal experts disagree on whether that access extends to training data or model weights, the numerical values an AI model learns during training.
The DSA also restricts targeted advertising to minors and the use of sensitive characteristics such as religion, ethnicity, sexual orientation, or political beliefs for advertising. Recommendation systems must become more transparent as well. The supplied reports do not yet establish what visible changes this will produce inside ChatGPT, and they do not mention changes to subscription plans or prices.
The Commission designated Reddit and Roblox as Very Large Online Platforms at the same time. Unlike ChatGPT, they are categorized as platforms because users distribute content created by other users. A short Ars Technica report frames the regulatory burden as a result of rapid growth, although its supplied summary offers no further detail.
Why is ChatGPT considered a search engine?
A conventional search engine mainly presents you with an ordered list of links. ChatGPT can search the web, combine information from several results into one response, and handle follow-up requests. For the EU, the underlying function appears to matter more than the conversational interface: a service that searches the web and responds to user queries is performing the work of a search engine.
A product search illustrates the difference. Instead of opening multiple results about clothing, household appliances, or electronics, you can ask a chatbot to organize your requirements and compare available information. This can save time, but it also shortens the path between the original source and your decision, potentially dropping context, objections, or relevant details along the way.
Switzerland’s 2026 e-commerce survey offers a concrete sign of this shift. Swiss Post and Ipsos questioned 1,050 people across all language regions. According to the analysis of product discovery in Switzerland, 1 percent of respondents used AI while shopping online in 2024, rising to 4 percent in 2025 and 9 percent in 2026.
Search engines such as Google and Bing remained the leading starting point in that survey, moving Digitec Galaxus into second place for product discovery. Younger people also begin searches more often on TikTok or Instagram. AI has not replaced conventional search engines, but it is becoming another entry point alongside search engines, online stores, and social media.
For people in Switzerland, the EU designation does not automatically turn the DSA into Swiss law. The supplied sources explicitly describe EU obligations. The development is still relevant in practice because Swiss consumers are increasingly using AI chatbots for shopping research, while much of the country’s online content is accessed through the same internationally available services.
How does AI search change content visibility?
Website owners, online retailers, and professional publishers have traditionally focused heavily on Search Engine Optimization (SEO). SEO means improving a page so that it can be found more easily in conventional search results. A strong Google position does not necessarily secure a place in an AI response, however, because the chatbot produces an answer rather than merely displaying a list of results.
The complementary approach is often described as optimization for generative search systems, or Generative Engine Optimization (GEO). It involves structuring content so a language model can identify and reuse individual claims more easily. A language model is an AI system that processes patterns in language and generates text from them.
A practical report on visibility in AI answers says these systems break documents into smaller text sections. These sections are commonly called chunks, meaning pieces of text processed separately. A model may therefore see one paragraph without receiving the complete article around it.
Consider an article explaining returns. A paragraph should not begin only with “The same deadline applies” if the product and return process are identified solely in the previous section. A more self-contained sentence would name the product category, the process, and the deadline together, provided each detail is supported. That helps both people scanning the page and systems processing the paragraph outside its original context.
The report recommends limiting each paragraph to one clear idea, using verifiable statements, and ideally keeping paragraphs below 250 words. It also says the main information should appear in the paragraph’s first sentence and early in the document, specifically within the first 350 to 400 words. These are editorial recommendations from one source, not an independently verified guarantee that ChatGPT will cite or link to a page.
This does not make SEO obsolete. The Swiss survey instead shows that traditional search engines remain central to product discovery. A more realistic approach is to treat SEO and GEO as overlapping tasks: pages must remain discoverable and understandable to people, while individual paragraphs should be clear enough to survive outside their original context.
Pros and Cons of AI Search
Pros:
- Direct responses – You receive a summarized answer and can ask follow-up questions instead of opening every result separately.
- Simpler comparisons – A single request can combine criteria for clothing, electronics, or household appliances.
- More EU oversight – Risk assessments, transparency reports, and complaint procedures add scrutiny to a widely used service.
- Another route to visibility – Clearly structured professional content may support AI answers as well as conventional search results.
Cons:
- Less visible sourcing – A ready-made answer may reduce the likelihood that you inspect original material, limitations, and competing views.
- Unclear selection – The supplied sources do not fully explain how ChatGPT chooses or names particular web sources.
- Additional dependence – Organizations may need to monitor their presence in AI systems as well as their Google performance.
- Unsettled enforcement – The scope of researcher access, regulatory audits, and user-facing changes remains unclear.
What does this mean in practice?
If you are new to AI search, start with a limited task. You could ask ChatGPT to organize the criteria for buying a household appliance, then verify prices, delivery terms, and return rules directly with each retailer. This reflects the Swiss survey, where transparent costs and straightforward delivery and return processes remain important despite changing search habits.
Do not rely only on a summary for sensitive or disputed topics. Open the cited material, check its date and original context, and deliberately look for a competing view. Stronger EU rules are intended to reduce risks, but they do not automatically make every individual response correct or complete.
If you already publish content, review existing pages one paragraph at a time. Each section should have a clear subject, a central claim that makes sense independently, and traceable support. Answers to key questions should appear early; long introductions and vague references make navigation harder for both people and language models.
More experienced publishers can compare which passages appear in conventional search results with which sources ChatGPT names for similar queries. This may reveal editorial weaknesses, but it cannot produce a reliable formula for inclusion. According to the GEO practice report, a page can rank on Google’s first page and still be absent from a ChatGPT response.
Organizations also face a maintenance task. Product information, costs, delivery conditions, and return policies should be stated clearly and kept current on their own sites. If a chatbot repeats outdated or compressed information, the convenient answer can become an additional source of errors. The supplied reports provide no reliable method for forcing a system to adopt or correct such details.
The EU is no longer treating ChatGPT solely as novel conversational software, but as a search service with broad social reach. Users may gain additional oversight without escaping the basic weaknesses of summarized AI responses. For content publishers, GEO supplements conventional search optimization, while source selection and the practical reach of the new controls remain unresolved.
