Does a translated dental site hurt your Google rankings?

The short answer

No. A translated version of your site doesn't hurt your Google rankings, not when it's built correctly. A German or Norwegian patient searching in their own language is running a different search from the one your local patients type, and Google treats it as a different search.

The worry is fair. You spent years earning your local ranking, and a second site could compete with the first or get read as a copy. That can happen, but it's avoidable, and none of the four things below touch the site you already have.

1. Different languages are not duplicate content

Duplicate content is the same text, in the same language, at two web addresses. Google usually distrusts both copies because it can't tell which one to show.

A German page and an English page aren't duplicates. They answer different searches for different people. Google has said this directly, and it indexes translated pages as distinct pages, each ranking in its own language. Your English page keeps competing in English while your German page competes in German, so they're never really up against each other.

2. It lives on a separate subdomain, so your site is untouched

DentalPolyglot mirrors your site to a separate subdomain, clinic.dentalpolyglot.com. Your original site stays where it is. We add no script to it, change no redirect, and touch no page on it.

That separation is the point. Your local site keeps its own ranking, its own history, and its own authority, because nothing about it changes. The translated site is a distinct property that earns its own standing over time. If you leave, you export your translations as JSON, redirect the subdomain, and since your original site was never altered, there's nothing on it you'd have to put back.

3. Correct hreflang tells Google which language serves which visitor

hreflang is a small tag in each page's code. In one line it tells Google: this is the German page, and here are its counterparts in English, Italian, and Norwegian. Google reads that and serves the right language to the right person.

This is the tag that links a set of translated pages into one connected site. Get it wrong and Google can show a Norwegian patient your English page, or read your languages as competing versions of one thing. Get it right and every language points cleanly at every other, so the languages read as one clinic speaking several. We generate these tags for every page and every language, and keep them in sync when a page changes. When it's working you never notice it, and when it isn't the damage is quiet, which is why we'd rather it not be something you have to track.

4. Per-language sitemaps make every page findable

A sitemap is the index you hand Google of every page on the site. We generate one per language, so Google finds your German pages as German and your Italian pages as Italian, with none left waiting to be discovered.

Paired with the hreflang tags from the last section, that is what puts a readable page in front of each patient. Google gets a clean map of every language and shows the German page to someone searching in German, the Italian page to someone searching in Italian. That is the whole reason you translate, and it only works when the map and the tags are correct.

The honest version

These aren't tricks. It's the documented way to run a multilingual site. Nothing here works against Google, because the whole design tells Google the truth: one clinic, several languages, each page meant for a specific reader.

What we won't claim is a ranking number. We're still signing our first clinics, so we have no ranking figure to show you, and we're not going to invent one. A new site's search authority in a new language builds over weeks and months, the same way your local site built its authority years ago. What we will say is that it's built so the languages help each other instead of competing, and so your existing site is never put at risk to get there. The technical detail behind each of these four lives on the SEO feature page.
