What is CocCocBot?
CocCocBot is the web crawler for Coc Coc, Vietnam's leading domestic search engine and web browser. Launched in 2013, Coc Coc has captured significant market share in Vietnam by providing search results optimized for Vietnamese users, including better handling of Vietnamese language with its tonal marks and diacritics. The crawler focuses on indexing Vietnamese content while also crawling international sites. Coc Coc's understanding of local context and language nuances makes it essential for reaching Vietnamese internet users effectively.
