Project Overview
Toan Cau Visa (TCVS), one of the leading visa consulting companies in Vietnam, experienced a major SEO crisis after mistakenly hiring a black hat SEO service. The website was heavily penalized by Google, resulting in a complete loss of search traffic and keyword rankings. In an industry where paid advertising is highly restricted, organic search is the most critical channel for customer acquisition. The loss of search visibility directly impacted lead generation and inbound calls.
DMAT partnered with Toan Cau Visa to recover from this crisis, rebuild their SEO foundation, and set them on a sustainable growth path.

- High-Quality Link Building: Secured new backlinks from reputable media outlets and authoritative blogs to regain domain authority.
- Google Reconsideration Request: After the cleanup, a formal request was submitted to Google to lift the penalty and re-index the website.
