Over the years, our trilingual agency website has grown into a comprehensive platform featuring projects, service pages and editorial content. As the website evolved, so did our technical requirements. We needed a solution that would preserve our existing content and organic search visibility while providing greater flexibility for future development.

## The Strategic Decision

The goal was not to adopt the latest technology, but to identify the architecture best suited to our long-term needs. Webflow had served us well, but the next stage required greater control over the frontend, independent content management and less reliance on a single platform.

We chose Astro and Sanity: Astro for a lightweight, high-performance website and Sanity for flexible, structured content management across three languages.

## The Implementation

We rebuilt the website using Astro and migrated the existing content from Webflow to Sanity. This involved redefining content models, connecting multilingual content and converting existing page layouts into reusable components. Particular attention was given to preserving URL structures, metadata and internal links to protect organic search visibility throughout the migration.

With Astro and Sanity, we created a flexible, scalable trilingual platform. The experience allows us to better advise clients on technology choices and SEO-conscious website migrations.
