This means that ChatGPT has been classified as a 'search engine'.
Discussions on AI search regulation have entered a new phase as the European Commission designated ChatGPT as a 'very large online search engine' under the Digital Services Act on August 31, 2026. This measure can be seen as an institutional recognition that generative AI services function as a search infrastructure that enables users to find and evaluate information, going beyond simple conversational tools.
In particular, ChatGPT, EU regulations, AI search, GEO, and the Digital Services Act have become key keywords that content creators, companies, and search users alike must understand going forward. This is because standards regarding which information is exposed and what liabilities follow are becoming increasingly important as search results shift from list-based links to AI-summarized answers.

What is a 'very large online search engine' as defined in the Digital Services Act?
The Digital Services Act, or DSA, is a regulatory framework established by the European Union to manage the impact of online platforms and search services on society. This Act addresses various obligations, including illegal content, misinformation, user protection, algorithm transparency, advertising transparency, and researcher access.
Among them, 'very large online search engines' is generally known as a category referring to search services with an average of 4,500 million or more monthly users within the European Union. Previously, traditional search engines such as Google Search and Bing were the primary targets, but with ChatGPT being included in this category, AI-based information search services have also come under the scrutiny of search regulations.
Why can ChatGPT be viewed as a search engine?
Traditional search engines display a list of relevant web pages when a user enters keywords. In contrast, AI search services like ChatGPT generate answers based on various information and, in some cases, present sources or web search results alongside them. Although the format differs, from the user's perspective, it is very similar to the act of searching in that it involves "asking questions and obtaining answers."
- Users enter questions and receive summarized answers rather than navigating the website directly.
- AI synthesizes information from various sources and provides it in the form of a single explanation.
- The order of answers, selection of sources, and omitted information directly influence the user's judgment.
- As search results shift from link-centric to answer-centric, the allocation of responsibility becomes more complex.
In other words, designating ChatGPT as a search engine is not merely a change of name. It signals that the way AI arranges and interprets information can also be subject to public regulation.
Key obligations arising from DSA designation
If designated as a very large online search engine, a higher level of management obligations is imposed than on general online services. While the specific application methods may vary depending on the service structure and the Commission's supervisory procedures, the general direction is as follows.
| 구분 | Main Content | Meaning in AI Search |
|---|---|---|
| Systemic Risk Assessment | Regularly analyze the risks that the service poses to society and users | Check for false information, bias, distortion of election information, errors in health and financial information, etc. |
| Risk mitigation measures | Establish operational policies to reduce identified risks | Answer verification, source attribution, restrictions on sensitive topics, and enhanced safeguards are possible. |
| Transparency Report | Disclosure of content adjustment, algorithm operations, and risk response status | Increasing demand for explanations on AI response generation and search exposure methods |
| External Audit | Verify compliance with obligations through independent review | Expanded possibility for third-party verification of AI search quality and safety |
| Researcher approach | Providing access to certain data for public interest research | Research on the impact of AI search on the information ecosystem may become easier. |
These obligations do not mean that the government pre-censors every single answer generated by AI. The key point is that, given the significant social impact of large-scale information services, risks must be predicted, explained, and managed responsibly.
What is the focus of AI search regulation?
As AI search expands, convenience increases, but new risks arise at the same time. While traditional search allowed users considerable room to compare multiple pages and make judgments, AI search makes it easy for a single answer to appear as the 'correct answer.' This is the starting point for regulatory discussions.
1. Issues regarding the accuracy and source of the answer
Generative AI like ChatGPT excels at generating natural-looking sentences. However, just because a sentence looks natural does not mean it is accurate. Sources and timeliness are crucial, especially in fields such as law, medicine, finance, and public policy, where misinformation can lead to significant harm.
AI search regulations are evolving beyond a mere "do not make mistakes" to a direction where users must be able to verify the basis on which answers are constructed. It is highly likely that source links, explanations of answer limitations, indications of the up-to-date nature of information, and warnings regarding sensitive topics will become more important elements in the future.
2. Algorithmic Bias and Information Diversity
Search engines decide which information to display first. AI search goes a step further by summarizing and interpreting various pieces of information to create a single answer. In this process, specific perspectives may be excessively reflected, or minority opinions and local information may be omitted.
- Information from a specific language group may be given excessive priority.
- Popular sources are repeatedly cited, which may reduce information diversity.
- If commercial interests influence search responses, user trust may be undermined.
- It may become difficult to provide a balanced explanation of political and social issues.
The DSA's risk assessment obligation encourages continuous monitoring during the service operation phase, rather than treating such issues merely as retrospective controversies.
3. Transparency of Advertising and Recommendations
As AI search becomes more commercialized, the boundary between advertising and recommendations may become blurred. For example, if a user asks for a "good value laptop" and the AI recommends a specific product, it must be clear whether this is a purely informative judgment or an advertising exposure.
The Digital Services Act emphasizes transparency, ensuring that users can recognize advertisements as such. In AI search as well, there will be an increasing need to explain why specific brands, products, or services are included in the responses. This protects users' right to choose while also being linked to fair competition among companies.
4. Social risks of election, health, and disaster information
Massive search services serve as information hubs when social events occur. If incorrect answers spread in areas of high public interest, such as candidate information during elections, guidance on infectious diseases, and natural disaster evacuation procedures, the damage can be significant.
The focus of EU regulations is precisely on such systemic risk. More important than a single individual error is the structural possibility that errors are repeatedly transmitted to a large number of users. Therefore, AI search providers may be required to implement stricter verification frameworks in sensitive areas.
Why has GEO become more important?
GEO stands for Generative Engine Optimization, a strategy for optimizing content so that it is well understood and cited in a generative AI search environment. While traditional SEO aimed for top rankings on search results pages, GEO focuses on increasing the likelihood that content will be referenced as a reliable source when AI generates responses.
The news that ChatGPT has been designated as a search engine under EU regulations further amplifies the importance of GEO. As AI search becomes recognized as an official channel for information discovery, content from companies, media, and experts must possess credibility, structure, sourceability, and timeliness, rather than merely relying on keyword exposure.
The difference between SEO and GEO
| item | SEO | GEO |
|---|---|---|
| main goal | Secure a high ranking on the search results page | Secure the possibility of being referenced or cited in AI answers |
| Key Target | Search algorithms and user clicks | Understanding Generative AI, Summary, Selecting Sources |
| Content format | Keyword, title, internal link, meta information centered | Clear explanations, structured information, evidence and context-centered |
| Performance indicators | Ranking, Click-through Rate, Traffic | AI mentions, increased brand awareness, direct search, trust signals |
| Important factors | Technical SEO, backlinks, meeting search intent | Expertise, source, recency, consistent entity information |
Content Creation Principles for the AI Search Era
There is no need to resort to special tricks for GEO. On the contrary, content that helps users seeking reliable information is more likely to receive a good evaluation in AI search. However, a structure that is clearer and more verifiable than the existing one is required.
- It clearly presents the topic and conclusion. Since AI grasps the context to construct answers, the likelihood of a quote decreases if the core message is unclear.
- I will explain the rationale and limitations together. For information subject to change, such as regulations, statistics, and laws, the reference date and scope of interpretation must be specified.
- We are strengthening question-based content. Since users frequently use natural language questions in AI search, FAQs, comparison tables, and step-by-step explanations are advantageous.
- It includes expert perspectives and real-world examples. Content that provides context and application methods is more valuable than a simple summary.
- Consistently manages trust signals between the brand and the author. Company names, service names, author introductions, contact information, policy documents, etc., must not conflict with each other.
The important point is that GEO is not a concept that replaces SEO. In an environment where search engine result pages and AI responses coexist, SEO and GEO must be considered simultaneously. A realistic approach is to build upon the technical foundation for search exposure by adding high-quality information structures that are easy for AI to understand.
Points for Content Creators to Watch Out For
As AI search expands, content can be utilized more extensively; however, conversely, the "zero-click" phenomenon—where answers are consumed without visiting the original site—may also increase. Therefore, content creators must go beyond simply providing information and create reasons for users to visit the source material.
- Includes proprietary data, interviews, and case analyses.
- It provides formats worth saving, such as tables and checklists.
- We update regularly to keep it up to date.
- It enhances credibility by clearly citing sources and author information.
- It provides in-depth explanations and practical judgment criteria that are difficult for AI to summarize.
Ultimately, the core of GEO is closer to 'becoming information trustworthy enough for AI to refer to' rather than 'making a good impression on AI.'
Changes to be made for businesses and users
ChatGPT's designation as a major search engine is not just an issue for Big Tech companies. It can impact everyone, from companies connecting with customers through AI search and general users seeking information to public institutions and media outlets.
Changes from a corporate perspective
Going forward, companies must examine more closely how their information is summarized in AI search. If product descriptions, pricing policies, refund policies, customer service information, press releases, and job postings are outdated or inconsistent, it can lead to confusion in AI responses.
- You must keep the key information on the official website up to date.
- You need to structure frequently asked questions, policy documents, and product comparison information.
- You must check whether the brand name and service name are used consistently across external channels.
- You must have a monitoring system in place to respond if AI provides incorrect information.
- If targeting EU users, you must also review relevant regulations such as the DSA, the AI Act, and the Data Protection Regulation.
In particular, for industries where information trust is critical, such as finance, healthcare, education, travel, and legal services, AI search results can directly influence customer decision-making. Therefore, it is highly likely that content management will be more closely linked with legal and compliance reviews.
Changes that users can expect
Users can continue to enjoy the convenience of AI search while expecting a higher level of transparency and safeguards. For example, the source of answers may become clearer, or guidance from specialized agencies may be strengthened for sensitive topics.
However, stricter regulations do not mean that all answers will automatically become perfect. AI search still generates language probabilistically, and there may be limitations in reflecting the latest information. Therefore, users need to develop the habit of consulting official agencies, experts, and original documents when making important decisions.
The Role of Media and Public Institutions
Media outlets and public institutions become more important providers of source information in the era of AI search. This is because reliable source texts are required for AI to generate accurate answers. The quality of the entire information ecosystem improves as public data, legal explanations, policy announcements, and statistical materials are provided in a structure that is easy for machines to understand.
For example, organizing press releases with text-based documents, summaries, dates, relevant departments, and related links, rather than providing them solely as image files, increases the likelihood of accurate interpretation in AI searches. This also provides better accessibility for general users.
Common misconceptions when understanding the new EU regulations
News of new regulations is often over-interpreted or consumed in a fragmented manner. The same applies to ChatGPT's designation as a major search engine. Distinguishing the misconceptions below will allow you to understand this measure more accurately.
Misconception 1. The EU restricts ChatGPT to search engines only?
That is not the case. ChatGPT can still offer various functions, such as conversational AI, productivity tools, coding assistance, and document creation tools. However, considering the scale of its user base and its information search capabilities, it is appropriate to understand this as meaning that responsibilities equivalent to those of a search engine under DSA will be applied.
Misconception 2. All AI search responses are pre-screened?
The DSA is generally not a law in which the government pre-approves individual responses one by one. The core purpose is to enable platforms to assess risks, mitigate problematic structures, and report transparently. Of course, additional requirements regarding sensitive areas may arise during the specific enforcement process.
Misconception 3. Is GEO a technology designed to evade regulation?
GEO is not a method to evade regulations, but a content strategy that provides information clearly and reliably tailored to the generative AI search environment. Attempts to manipulate AI responses with false information or exaggerated claims are highly likely to damage brand trust in the long run.
Misconception 4. It has nothing to do with Korean companies?
This is relevant for companies providing services to EU users or seeking to acquire customers in the European market. Furthermore, EU regulations often serve as a benchmark for global technology policy. Even if you are not directly subject to these regulations, it is advisable to understand the direction of AI search regulations.
Misconception 5. Search will now all be replaced by AI?
While AI search is growing rapidly, it is unlikely that traditional search will disappear in the short term. Existing search methods still hold strengths in areas such as complex comparisons, original text verification, shopping, local exploration, and image and video searches. Moving forward, it is highly probable that a hybrid search environment combining link search and AI responses will become the norm.
