Vietnamese search agency for large enterprises, with SEO, Google Ads and Maps management
About SEONGON
SEONGON, registered as SEONGON Thinh Vuong Joint Stock Company, is a Vietnamese search marketing agency with offices in the Lixil Building on Bich Cau Street in Hanoi and on Nguyen Thi Minh Khai Street in Ho Chi Minh City. It was founded in 2012 (some listings say 2011). Mai Xuan Dat is founder and chairman and Luu Trong Hieu is chief executive, with directors for sales and marketing and for SEO operations. The agency is now an AI-first search growth partner for large private companies and state-owned groups, with more than 2,500 clients and over 900 SEO projects.
The main SEO product, AI MAX Comprehensive SEO, pairs conventional technical, on-page and off-page work with optimisation for Google AI Overviews. Content is planned around search intent and E-E-A-T, keyword sets are widened through query fan-out, and authority is built through backlinks, media mentions and multi-platform presence. An internal AI Center studies AI search behaviour and competitor visibility. Engagements usually run six to nine months with a dedicated team, starting with an industry report and roadmap, and reports cover rankings, search traffic, and brand share within AI Overviews.
For multi-branch businesses the agency sells Total Business Map, a Google Maps and Apple Maps service aimed at chains of roughly 50 to 10,000 locations. It covers verifying and consolidating ownership of each listing, removing impersonating listings, review monitoring and alerts, scheduled posts, incident response and dashboards fed by the Google Business Profile API. Maintenance contracts run 6, 9 or 12 months.
Healthcare appears as one of seven industry solutions, and clients include Vinmec Hospital, IVF Quốc Ánh, An Thịnh Obstetrics Hospital, Gentis, Traphaco and the dental clinic Nha Khoa Lạc Việt Intech. No dental case study is published. Featured results come from other sectors: CMC Tiles reached 90.3 percent of keywords in the top 10 with 500 percent organic traffic growth, Cibes saw a 400 percent organic traffic rise, and Decumar a 16-fold increase. Larger brand clients include Techcombank, VNPAY, Vietnam Airlines, Decathlon and Vinamilk.
The agency won a 2024 Google Agency Excellence Award and a 2023 Premier Partner Award for workplace excellence, and has 2026 Global Search Awards entries in finance, travel and retail SEO. On Clutch and The Manifest it holds 5.0 from three reviews, which mention value for money and on-time delivery. Prices are not published; fees are higher than some competitors and the most common project size is $10,000 to $49,000. It fits Vietnamese dental chains and hospital groups more than single-chair practices.
