What is CocCoc?

CocCoc is a Vietnamese web browser and search engine that launched in 2013.

It was developed by a team of both Vietnamese and international developers with the goal of catering specifically to the Vietnamese market. Unlike global platforms, CocCoc addresses the unique linguistic and cultural needs of Vietnam.

As of September 2024, it holds around a 2.5% market share in Vietnam versus Google (96.4), and Bing (0.49%).

One of its main features is localized search. CocCoc excels at understanding Vietnamese language and dialects, offering search results that are more accurate and relevant for local users compared to major international search engines like Google.

In addition to search, CocCoc integrates localized maps, directions, and business listings. This makes it better suited for navigating Vietnam’s geography and accessing local businesses.

CocCoc also offers a full web browser. It includes features such as video downloading, faster file downloads, and tools to bypass geo-blocks on certain websites. This added functionality has made it a popular choice for users in Vietnam.

The platform also supports businesses through an advertising network similar to Google Ads. Companies can target Vietnamese users and optimize their content for CocCoc’s search algorithms, which helps them rank higher in local search results.

CocCoc is available on both desktop and mobile devices, contributing to its widespread use.

Over time, it has grown into one of the top web browsers and search engines in Vietnam, largely because of its focus on local needs and its range of features designed to enhance the Vietnamese online experience.

Dan Taylor is the founder and editor of International Search Insights (ISI), the publication behind ReadIsi, and a Partner and Head of Innovation (Search & AI) at SALT.agency. He has worked in search for more than a decade, in-house and agency-side, and is regarded as one of the West’s leading voices on search engines beyond Google, including Yandex, Baidu, Naver and Cốc Cốc. On ReadIsi, Dan covers the engines and AI answer platforms that English-language coverage tends to miss: Baidu and ERNIE, Yandex and Alice AI, Naver, Cốc Cốc, Shenma, Sogou, WeChat and Weibo search, plus DeepSeek and Alibaba’s Qwen. He also keeps dated records of documented changes, such as the Yandex, Baidu and Naver algorithm update histories and the DeepSeek, ERNIE and Qwen model update histories. His approach is to take learnings from global search engines and apply logic with a high evidence threshold. A claim needs a source, patterns seen in one market are treated as a hypothesis until they are checked in another, and where the evidence is thin he says so. For brands, that means advice built on what can be shown, with measurement that separates being cited from being chosen. Dan is credited with coining the term “edge SEO” and won the inaugural TechSEO Boost research competition in 2018 for his work on CDN and edge changes for SEO. In 2026 he was credited with coining “Infinite Tail” to describe how keyword research is changing with AI search. He is the author of AI Search Marketing For The Travel Sector, writes for Search Engine Journal, Search Engine Land and Travel Marketing Guy, and has advised technology, SaaS, travel and enterprise ecommerce brands, including Cloudflare, GitLab and Airbnb. He has given multiple talks and panels at the International Search Summit in Barcelona, and has also spoken at Optimization Moscow, brightonSEO, Google Search Central Live Deep Dive Asia in Bangkok, Athens SEO and the Asia SEO Virtual Summit 2026, where his talk looked at how Baidu, Naver, DeepSeek, Tencent, Cốc Cốc and Yandex built their own AI answers.
