Localization Center: manage languages and translations

The Localization Center helps you manage the languages of your website.

You can create a multilingual site, review translations, set the main language, and make sure content appears correctly for each audience.

When to use the Localization Center​

Use the Localization Center when you want to:

  • add a second or third language,
  • change the main website language,
  • review translations,
  • correct copy in another language,
  • adjust SEO per language,
  • check multilingual navigation,
  • publish a site for an international audience,
  • have different content per country or language.

What is a multilingual website?​

A multilingual website is a site with content in more than one language.

Example:

  • Greek,
  • English,
  • Spanish.

Each language can have its own copy, SEO details, URLs, buttons, forms, and messages.

Step 1 — Open Localization Center​

Open the Centuply app, select your website, and open Localization, Languages, or Localization Center.

There you will see available languages and translation settings.

Step 2 — Check main language​

The main language is the default language of the website.

It is usually the language in which the website was originally created.

Examples:

  • Greek for a Greek business,
  • English for an international audience,
  • Spanish for a Spanish-speaking audience.

The main language should match the business's primary audience.

Step 3 — Add languages​

If you want a multilingual site, add the languages you need.

Do not add many languages without a reason.

Each extra language needs:

  • copy review,
  • SEO review,
  • correct buttons,
  • correct forms,
  • proper publish check.

Step 4 — Create or update translations​

Depending on website capabilities, translations may be generated with AI or updated manually.

Check that the following are translated correctly:

  • hero titles,
  • subtitles,
  • service descriptions,
  • buttons,
  • forms,
  • confirmation messages,
  • SEO titles,
  • meta descriptions,
  • navigation labels,
  • footer text.

Step 5 — Check tone in each language​

Translation should not be only word-for-word.

It should sound natural in the visitor's language.

Check:

  • whether the tone is professional,
  • whether sentences sound natural,
  • whether words fit the audience,
  • whether CTAs are clear,
  • whether there are strange translations.

Step 6 — Check navigation and links​

On a multilingual site, links should point to the correct language.

Check:

  • menu items,
  • footer links,
  • buttons,
  • CTA links,
  • blog links,
  • service links,
  • language switcher.

If the visitor is on the English version, they should not suddenly be sent to Greek content without a reason.

Step 7 — Check forms per language​

Forms should appear in the correct language.

Check:

  • labels,
  • placeholders,
  • validation messages,
  • submit button,
  • confirmation message,
  • error messages,
  • consent text.

If a site has an English form but a Greek confirmation message, the experience feels unfinished.

Step 8 — Check SEO per language​

Each language should have correct SEO details.

Check:

  • page title,
  • meta description,
  • slug,
  • headings,
  • social preview,
  • alt text,
  • local keywords, if needed.

Do not always copy the same SEO content from one language to another without adaptation.

Step 9 — Check language switcher​

The language switcher should be clear and easy to use.

Check:

  • whether the correct languages appear,
  • whether switching language works,
  • whether it keeps the visitor on the matching page,
  • whether it looks correct on mobile,
  • whether it is not hidden inside the menu.

Step 10 — Preview each language​

Before publishing, preview each language separately.

Check:

  • Home page,
  • Services,
  • Contact,
  • Forms,
  • Blog,
  • Footer,
  • SEO preview,
  • mobile view.

Do not check only the main language.

Step 11 — Publish multilingual site​

When all languages are ready, publish.

After publishing, open the live website and check again:

  • default language,
  • each translated URL,
  • language switcher,
  • mobile menu,
  • forms,
  • CTA links.

Best practices​

  • Do not add languages you will not maintain.
  • Review each translation before publishing.
  • Keep the tone natural.
  • Check SEO per language.
  • Test the language switcher on mobile.
  • Do not leave half-translated pages.
  • Check forms and confirmation messages.
  • Run a live check after publishing.

Frequently asked questions​

Do I need a multilingual website?​

Not always. It is useful if you serve audiences that speak different languages.

Can I have different content per language?​

Yes, if supported. Sometimes content needs adaptation, not just translation.

Should I review all translations?​

Yes. Before publishing, review every language.

Should SEO be translated?​

Yes, but it is best to adapt it to the language and audience.

What if a page has no translation?​

Complete the translation before publishing or hide the page from that language, if supported.
