Mạnh Digital

Mạnh Digital is an SEO and AI search agency based in Hanoi, Vietnam. Founder Nguyễn Thế Mạnh has worked hands-on in SEO since 2022 and personally audits each website, plans the work and reviews every task before it goes live.

The work falls into three services. Full-scope SEO covers six pillars of website SEO, with the number of articles, target queries and referring websites written into the contract. SEO AI (GEO and AEO) standardises a business’s information across the web, writes content that AI answers can quote and opens the site to AI crawlers. It is included in every SEO package. AI Agent SEO runs an agent on Claude that reads Search Console and GA4 every day, proposes on-page fixes, drafts articles and fixes technical issues. Nothing goes live until the person in charge approves it.

Monthly packages start at 9,000,000đ, excluding VAT, and every price is published on the website.
