Automating website translation & localisation with the Claude API

Challenge

Dagard International needed to translate its extensive English-language website into French, Spanish, and Portuguese to serve key international markets. The manual process of translating 151 web pages and 7 database tables was prohibitively slow and expensive, particularly as dynamic, database-driven content could not be handled by HubSpot's native AI translation. Maintaining technical accuracy, especially for product and certification terms, and ensuring correct SEO and internal link structures were essential requirements. Dagard also required a workflow that enabled efficient reviewer sign-off and the capacity to deliver multiple languages within tight deadlines.

Results

By implementing SpotDev's Hublingo technology, Dagard International achieved fast, consistent, and technically accurate translation of 144 web pages and 7 HubDB tables into French, with Spanish and Portuguese variants delivered at a much lower incremental cost. The automated pipeline ensured robust terminology management, seamless SEO and link mapping, and systematic quality assurance. Translation costs and project duration were cut by more than half, and the process facilitated efficient reviewer approvals and set a scalable foundation for future multilingual expansion.

About Dagard

Dagard International is a French manufacturer specialising in modular cleanrooms, cold rooms, and controlled environment panel systems, serving industries such as food processing, pharmaceuticals, healthcare, logistics, defence, and electronics. 

The Challenge

Dagard International, a leader in modular cleanrooms and controlled environment panel systems, faced the complex task of translating its comprehensive English website for new European markets. With 151 pages and 7 dynamic HubDB tables containing specialised terminology and certification data, the company found that manual translation was not only resource-intensive and slow, but also incapable of reliably localising database-driven content.

HubSpot's built-in translation tools could not guarantee technical accuracy or manage dynamic content, making it difficult to maintain product nomenclature, internal links, and SEO attribut

es across languages. Dagard required a streamlined, scalable process that protected technical accuracy and supported rapid, multi-language delivery with clear reviewer controls.

The Solution

Dagard partnered with SpotDev to address these challenges using Hublingo, SpotDev's automated translation pipeline.

Hublingo connects directly to HubSpot CMS and HubDB via API, extracts structured website content, and leverages the Claude API for high-quality translation, guided by a client-specific glossary to ensure technical terms are accurately rendered. The system then publishes new language variants with correct technical configuration, link mapping, and SEO tagging.

The process also built in reviewer workflows, so no language variant went live without approval, meaning no language variant publishes without the client's named reviewer accepting it. Model output is treated as a draft that a native speaker approves. This ensured both speed and reliability in launching multilingual content.

The Results

Following implementation, Dagard rapidly delivered 144 audited French pages with full SEO and terminology consistency. Spanish and Portuguese variants followed at significantly reduced incremental cost.

The Hublingo workflow enabled rapid translation runs, systematic quality assurance, and one-to-one internal link mapping. This process surfaced and resolved both source and translated site issues.

Translation cost savings exceeded 50%, and the streamlined workflow enabled timely reviewer sign-off. As the SpotDev project team summarised: "Translating 151 pages one at a time in the HubSpot editor, then repeating the exercise for two further languages, is slow and expensive, and the cost rises linearly with every language added."

SpotDev's approach established a scalable foundation for Dagard to add new languages efficiently in the future, driving international growth while maintaining technical and brand integrity.
