In this blog post, we’ll examine the issues with Naver as a search engine in terms of effectiveness, diversity, and transparency, and consider them in the context of today’s search landscape.
Introduction
What is the website that South Koreans visit most often and most frequently? Many people would likely think of Naver first. Naver has long established itself as one of South Korea’s leading portals. A portal is a website that comprehensively provides the various services users need when they connect to the internet and launch a web browser.
In the past, Naver held an overwhelming lead in monthly unique visitors, but the search landscape has changed significantly. As mobile-centric internet use has become widespread and platforms like Google, YouTube, various specialized platforms, and generative AI search services have proliferated, competition in the search market has intensified. Nevertheless, Naver continues to maintain a high usage rate in South Korea and remains one of the country’s leading search platforms.
As someone working in online marketing, I frequently used Naver. However, after encountering various issues—such as the classification of low-quality content—I consulted with Naver’s customer service center on multiple occasions and realized that these problems were structural in nature and difficult to resolve in the short term. Since then, I have increasingly turned to Google first when searching for information, not only as a marketer but also as a general search user.
As such, Naver has consistently been the subject of debate across various aspects, including its role as a search engine, its method of organizing information, search results centered on its own content, and the transparency of its search algorithms. Of course, evaluations of these issues may vary depending on the time and perspective, and Naver is also continuously improving its search quality and algorithms. Therefore, in this article, I will focus on the role of the search engine—the most important function of a portal—to examine Naver’s characteristics and limitations.
Main Body
Before examining Naver as a search engine, it is necessary to first look at the overall trends in the global search market.
In the past, search engine market share varied significantly by country, with Baidu dominating in China, Yandex in Russia, Yahoo! Japan in Japan, and Naver in South Korea. While differences still exist today, Google maintains the highest market share in most countries within the global search market. However, in some countries such as China and Russia, domestic search engines still wield significant influence, and patterns of search service usage vary depending on each country’s internet environment, language, culture, and policies.
Since the development of the IT industry and internet culture differ from country to country, it is difficult to judge the relative merits of search engines by simply comparing specific ones. Therefore, this article will focus on the essential roles that search engines should fulfill, rather than on the market environments of individual countries.
What role should a search engine play? I consider three factors to be particularly important. First is effectiveness—the ability to accurately find the information users seek; second is diversity—providing information from various sources; and third is transparency—ensuring that search results are trustworthy. I will now examine Naver’s strengths and limitations based on these three criteria.
Effectiveness
The effectiveness referred to here means how accurately and quickly users can find the information they want when using a search engine.
In the past, several surveys have shown that user satisfaction with the search function itself was higher for Google than for Naver. On the other hand, Naver was sometimes rated higher for its design, convenience features, and various value-added services. These results demonstrate that the competitiveness of search functions and that of portal services are not necessarily the same concept.
In fact, when comparing the same search terms across multiple search engines, there are cases where the desired information can be found easily, but there are also instances where, depending on the type of search term, it is difficult to find the desired results on a specific search engine. While it is difficult to definitively judge the performance of a specific search engine based solely on such cases, it is true that various evaluations have been made regarding the accuracy of search results.
Of course, it is not appropriate to evaluate the overall performance of a search engine based on just a few search examples. Furthermore, Naver has also been continuously improving its search quality compared to the past by applying various technologies such as AI-based search, enhanced integrated search, and user intent analysis.
Nevertheless, the fundamental role of a search engine is to provide the information users want in the most appropriate form. Therefore, whether search results are overly biased toward specific services or content and how accurately they provide information that best matches the user’s search intent will remain an important evaluation criterion in the future.
Diversity
The term “diversity” here refers to the range of sources from which search results are drawn when using a search engine.
In the past, when users entered various search terms on Naver, Naver services—such as Naver Shopping, Blogs, Cafes, Knowledge iN, and News—were often prioritized at the top of the search results. While this structure has the advantage of allowing users to find most of the information they need within Naver itself, there have been consistent concerns that it reduces opportunities to access information from external websites or diverse sources.
The search terms cited in the original article—such as “Chuseok gifts,” “preparing for the new semester,” and “job application cover letters”—are also presented as examples where Naver’s own services account for a significant portion of the search results. At the time, this arrangement of search results served as grounds for criticism that Naver was prioritizing its own services over external content.
Of course, Naver’s search results have undergone significant changes compared to the past. The search algorithm has been continuously improved to ensure that a variety of sources—including external websites, news outlets, official websites, and specialized information sites—are displayed together, and the proportion of external content has increased compared to before, depending on the search intent. Nevertheless, some users and experts still argue that the proportion of Naver’s own services in search results remains relatively high.
Diversity in search results does not simply mean displaying a large amount of information; it means providing a balanced mix of information from different perspectives and sources. Therefore, search engines need to organize search results in a way that allows users to compare and evaluate diverse information without being overly biased toward any specific platform or service.
Perceptions regarding SEO (Search Engine Optimization) are also tied to these issues. Overseas, SEO has evolved toward improving the quality of websites themselves and enhancing the competitiveness of their content. In contrast, in South Korea, the method of securing visibility in Naver’s search results has long been perceived as the core of SEO. In particular, as exposure strategies centered on blogs, online communities, and Knowledge iN were actively shared, various techniques for achieving search visibility emerged.
Along with this, concerns about promotional content have been consistently raised. Critics have pointed out that the difficulty in distinguishing between reviews written by actual users and promotional posts created by companies or marketing agencies undermines the credibility of search results. This issue is a common phenomenon not only on Naver but also on most search platforms and social media sites, and continuous improvements are currently being made through the use of AI-based quality assessment and spam detection technologies.
However, when evaluating these issues of diversity, it is necessary to also consider the context in which Naver grew. At a time when South Korea’s internet environment had not yet fully matured, Naver actively fostered its own services—such as Knowledge iN, Blogs, and Cafes—to expand Korean-language content. As a result, a vast amount of Korean-language content was accumulated, and the search service has evolved around this foundation.
However, the search landscape has changed significantly. In addition to Naver, high-quality Korean-language content is now being produced on numerous websites and specialized platforms, and the number of users searching for overseas content is steadily increasing. Therefore, further expanding the diversity of search results and providing a balanced mix of external and in-house content will remain a key challenge moving forward.
Transparency
The transparency referred to here refers to the extent to which search results and rankings are provided based on reliable criteria.
Since search engine algorithms constitute a company’s core technology, their specific inner workings are not fully disclosed. This applies not only to Naver but also to most global search engines, including Google. Therefore, the transparency of search results is less a matter of disclosing the algorithm itself and more a matter of how much users can trust the results and whether the system operates consistently.
The transparency of search results is one of the most sensitive topics of debate. In the past, various controversies arose regarding search results related to specific issues or the operation of real-time search terms. However, in most of these cases, it was difficult to secure objective evidence, and given the nature of search algorithms—which are not disclosed—it was often challenging to verify the exact facts.
Blog search has also faced similar controversies. In the past, the term “low-quality blogs” was widely used; users who experienced a sudden, significant drop in visitor numbers or search visibility began using this term. However, Naver has consistently explained that it comprehensively evaluates the quality of individual documents along with various search quality factors, and has never officially acknowledged operating a policy specifically labeled “low-quality blogs.”
Today’s search algorithms have become far more complex than in the past. They comprehensively factor in various elements—such as the expertise, reliability, and originality of content; user engagement; spam detection; and document quality—while also actively leveraging AI technology. Consequently, it is difficult to judge the search algorithm based solely on the search rankings of specific blogs or websites.
Nevertheless, the fact that it remains difficult for users to fully understand the criteria by which search results are determined remains a challenge to be addressed. For search engines to gain trust, they must not only continuously improve search quality but also continue to make efforts to clearly communicate their search policies and quality control principles to the greatest extent possible.
Conclusion
So far, we have examined the shortcomings of Naver as a search engine from three perspectives: effectiveness, diversity, and transparency. Effectiveness relates to how accurately the search engine provides the information users seek, while diversity refers to whether it presents information from various sources in a balanced manner. Furthermore, transparency is closely linked to the extent to which users can trust search results and search algorithms. These three elements constitute the core competitive strengths a search engine must possess and serve as key criteria for evaluating the quality of search services.
Of course, considering the background that allowed Naver to grow into South Korea’s leading portal, it is difficult to view all of its issues solely in a negative light. Naver contributed significantly to the growth of South Korea’s internet ecosystem by establishing various services—such as Knowledge iN, blogs, and Cafes—at a time when the Korean-language internet environment was not yet fully developed. Furthermore, it continues to adapt to the changing internet landscape by actively pursuing initiatives such as AI search, generative AI-based services, and improvements to its search algorithms.
On the other hand, the search landscape is changing much more rapidly than in the past. With the emergence of not only global search engines like Google but also generative AI-based search services, specialized platforms, and various content services, users’ search behaviors are also changing significantly. Search engines are now evolving beyond simply displaying large amounts of information; they are moving toward accurately understanding user intent and efficiently providing a variety of reliable information.
As a user of Naver’s various services myself, I hope that Naver will continue to maintain its competitiveness in South Korea’s search market. To achieve this, it is necessary to further improve the accuracy of search results, provide content from diverse sources in a balanced manner, and continuously build trust in its search policies and quality control. If these improvements are consistently implemented, Naver will not only maintain its competitiveness as South Korea’s leading search engine but also continue to play a positive role in the development of the country’s internet culture and information ecosystem.
