Spain is not a monolingual market
With over 80 million tourists per year and a growing community of international residents — more than 6 million registered foreign nationals — Spain is one of the most multilingual markets in Europe. In Barcelona alone, 23% of the population is of foreign origin. If your website is only in Spanish, you're shutting out a significant chunk of your potential customer base without even realizing it.
This is especially critical for businesses in cities like Barcelona and Madrid, where international clients can represent over 40% of the target audience. Restaurants, clinics, hotels, travel agencies, and import-export companies know this firsthand: language is the first barrier — or the first bridge. A German tourist who finds your hotel's website in their own language is not only more likely to book, but tends to spend more and leave better reviews.
Google Translate is not a multilingual strategy
A professional multilingual website is not a machine translation button. The result of running Google Translate on a dental clinic's website can be comical — or directly damaging to your reputation. A real multilingual site means creating a native experience in each language: culturally adapted copy (not literal translations), localized URLs (/en/ vs /zh/), hreflang tags so Google shows the right version to each user based on location and language, and typography that works as well with Latin characters as with Chinese, Arabic, or Korean.
The difference shows in the numbers. A site with automatic translation has a bounce rate of 70-80% on the translated languages — users arrive, see the text isn't natural, and leave. A site with native content in each language maintains bounce rates similar to the primary language, because users feel the site was made for them, not translated as an afterthought.
How we do it: multilingual architecture that scales
At Sastre Web, all our projects include native multilingual support with next-intl. This means each language has its own route (/es/, /en/, /zh/), its own SEO with independent meta tags and descriptions, and its own content — not a translation layered on top of the original. Google treats each version as a standalone page that can rank in its respective market.
Technically, this means: static generation of each page in each language for maximum speed, language switching without page reload, automatic browser language detection for first-time visitors, and a centralized management system where updating content in one language doesn't break the others. All of this sounds complex, but for the end client it's invisible — they just see a website that works perfectly in every language.
Real case: ChinaWay triples their market with three languages
Our project for ChinaWay — a real travel agency in Barcelona specializing in China — is the best example of what a well-executed multilingual website can achieve. Before working with us, their site was Spanish-only and they captured clients exclusively from the Spanish-speaking market. By launching English and Chinese versions, they tripled their market reach without tripling their ad spend.
Each language works as an independent acquisition channel on Google. The Chinese version attracts the Chinese community across Europe looking for trips to their home country. The English version captures travelers worldwide interested in visiting China. And the Spanish version maintains their local base. Three audiences, three SEO strategies, one single website managed from a single Payload CMS dashboard.
Where to start?
You don't need to launch 9 languages on day one. The smartest strategy is to start with the languages where your real audience lives. For most businesses in Spain, that means Spanish + English as a foundation, then adding Chinese, French, German, or Arabic depending on your industry and clientele. A hotel in Mallorca needs German and English. A Chinese restaurant in Barcelona needs Chinese and Spanish. An importer needs the language of their suppliers and the language of their customers.
If your business operates in Spain and serves international clients, a multilingual website isn't a luxury — it's a competitive necessity that your competitors without one are paying for in lost customers every single day. And with the right architecture, it doesn't have to be expensive or complicated: everything is managed from a single dashboard, just like a monolingual site.
