More languages sounds like more reach. In practice, it's often the opposite. Here's how to choose the right languages for your real estate website on the Costa Blanca, and why 3 done well beats 8 done poorly.
How many languages does your real estate website need?
Look at real estate agency websites on the Costa Blanca and you'll often see a row of flags across the top. Spanish, English, Dutch, German, French, Russian, Swedish. Sometimes more.
The logic makes sense: the more languages you offer, the more clients you reach. In practice, it often works the other way.
More languages can mean a worse website
Adding a language means adding content. Real content, written for that audience, reviewed for accuracy, maintained over time. That's the version of multilingual that works.
What most agencies actually do is run everything through Google Translate or a cheap translation service and call it done. The result is text that technically reads in another language but loses meaning in the process. Terminology gets mistranslated. Local legal concepts get garbled. Phrases that sound professional in Spanish read as awkward or confusing in Dutch.
Buyers notice. Maybe they can't identify exactly what's wrong, but something feels off. And when you're asking someone to trust you with a €400,000 purchase, "something feels off" costs you the client.
Research by CSA Research found that 65% of consumers prefer content in their own language and 40% won't buy at all from sites available only in other languages. But that effect works in reverse too: a poor translation actively signals that the business hasn't invested in understanding its audience.
Multilingual SEO
Automatic translation does not automatically create duplicate content. Google expects equivalent pages in different languages to cover substantially the same information.
What matters is that each language version has its own crawlable URL, is labelled correctly and contains useful content. Hreflang helps Google connect equivalent language or regional versions. Translation quality still matters for users, but different languages are not treated as a duplicate-content penalty.
Properly built multilingual sites use separate URL structures per language (/en/, /nl/, /de/) with real, independently written content for each. Each version is indexed separately and ranks in its own language's search results.
Maintenance is real work
Every time a listing changes, every time your services change, every time you add a blog post: that update needs to happen in every language you support. The more languages, the more work. The more work, the more likely something gets missed and a language version becomes outdated.
An outdated language version is almost worse than no version at all. A buyer who finds a Dutch page with old information now doesn't trust the English version either.
So how many languages?
The right number is the number you can maintain properly.
For many Costa Blanca agencies, Spanish and English are logical base languages, with Dutch added when the business actively serves Dutch and Flemish buyers. The commercially important languages vary by agency, location and actual client base; there is no universal top three that applies to every estate agent.
German, French or other languages make sense when you demonstrably serve those markets and can maintain the content properly. Base the decision on your own leads, sales data, search demand and target audience rather than a general assumption about the Costa Blanca market.
The real question is not how many languages are technically possible, but which ones you can maintain professionally and actually need commercially. Three well maintained languages are better than six outdated versions, but some agencies need two while others genuinely need four or five.
What proper multilingual looks like technically
A translation button or plugin is not a multilingual website. It looks multilingual to visitors but Google can't index it, which means it won't help you rank in Dutch or German search results.
Proper multilingual means separate URL paths, hreflang tags, and real content per language. It's the difference between showing up when a Dutch buyer searches "makelaar Costa Blanca" and being invisible to that search entirely.
The sites I build use this structure by default. The Professional package covers 3 languages, fully managed through the CMS with no technical knowledge needed.
