one.com's own way to add a language is to duplicate every page and translate each copy by hand, and its Online Shop can only appear once per site. SiteTran takes one Code component instead: your pages, shop, blog and forms are translated as they load, in Danish, Swedish, German, English or any language your customers read.
Driving growth for companies with millions of users
one.com sells two site builders and WordPress hosting. Find yours below: most sites are ready for SiteTran in a few minutes.
If your editor's Widgets panel has a Code component you can use, you're set. That's the Business, Pro and Ecommerce Website Builder plans, or the Premium and Business + E-commerce add-ons on a classic hosting plan.
These plans add Embed custom code when you upgrade, using the Upgrade button in the editor. Then follow the same three steps below.
one.com's newer, chat-based builder is a separate product with its own plans. Embed code is included, but you add it by asking Aida rather than from a menu. Ask Aida to put all three lines of your Widget Code on every page, then check your published site.
If you built your site with WordPress, including one.com's managed WordPress or Aida WP builder, skip the Code component and use the SiteTran WordPress plugin.
See the WordPress translator →From one.com's help center article “Which features are included in each Website Builder plan?”, checked October 20, 2026. Plans and names can change, so check your own editor too.
The one.com Code component runs your code on the page itself, so SiteTran can read and translate everything around it. Put it in your header once and it loads on every page.
Sign up free, add your site's address, select its original language, such as Danish or Dutch, and pick the languages to translate into. SiteTran gives you your Widget Code.
Open Website Builder from the one.com Control Panel. Click Widgets and choose Code (some editors list it under More). Keep Placement of code on Normal, paste all three lines and click Save.
Drag the Code component into your header, tick Apply to all pages under Settings › Placement, and click Publish. Then pick a language on your site and translate with AI, your own translators, or both.
<script>var sitetran = {site_id: your_site_id};</script> <script src="//c.sitetran.com/widget/v3.js"></script> <div id="sitetran_translate_element"></div>
SiteTran gives you your own ready-to-paste code, with your site ID already in it. The div is where the language dropdown is created.
Insert any HTML code including JavaScript.
Website Builder repeats the header on every page that uses the same template, and the Code component's Settings › Placement has an Apply to all pages option. Use both, so the shop, blog and pages you add later are covered.
The placement menu can also send code to the page head, which suits cookie banners. Keep the Widget Code on Normal: its div draws the language dropdown and belongs in the visible page.
The dropdown appears where the Code component sits. To keep it in a corner on every screen size, set Positioning to Fixed on window on the Dropdown Style page, or move it with CSS.
Positioning the Language Dropdown →SiteTran translates whatever Website Builder renders on the page. It keeps watching the page, so carts, messages and other text that appear later are translated when they appear.
Your menu, header text and footer are translated once and reused everywhere. Your page tree stays as it is, with no language level and no second menu to maintain.
The All products grid, Featured products and product widgets, button texts like Add to cart, the cart and the automatic shop footer are translated in every language, from the one shop you already run.
Posts, categories and dates shown on your blog page are translated when they appear, including AI-generated posts you edited in the blog dashboard. You keep writing each post once.
Field labels, placeholders, buttons and thank-you messages are translated. What a visitor types is submitted as typed, so a Swedish message arrives in Swedish.
Website Builder has a separate Mobile view editor where you can hide or reorder components. Your translations apply to both layouts. Just make sure the Code component isn't hidden on mobile.
Alt text is translated automatically. For a banner with text or a price list PDF, point each language to its own file with Translating Images & URLs.
Website Builder has no automatic translation. one.com's help center shows how to build a multilingual site by hand: one home page per language, duplicate pages beneath it, and a second menu as the language selector.
one.com was founded in Denmark in 2002 and launched Website Builder in 2012. Many of its sites are written in Danish, Swedish, Norwegian, Dutch or German first, so SiteTran treats any language as your original.
A ceramics studio, a design shop or a Faroese knitwear brand selling to Sweden, Norway and Germany from one Online Shop. Keep product names fixed with the Glossary and let everyone order in their own language.
A B&B on Texel, a holiday cottage in the Eifel or a guided bike tour welcoming guests from across Europe. Translate rooms, house rules and the booking request form without copying a single page.
A dental clinic in Malmö, an accountant in Oslo or a driving school in Odense whose clients are more at home in English, Polish, Ukrainian or Arabic. Machine translation does the first pass and a bilingual colleague checks it.
Since June 19, 2026, EU online shops selling to consumers must offer an easy way to withdraw an order online, and one.com's help center shows how to build the withdrawal form and footer button in Website Builder. SiteTran translates that button and form like any other text. For legal wording, use machine translation as a draft and have a reviewer approve it.
If the text is part of your page, SiteTran translates it, whether you wrote it or Website Builder generated it. That includes pages you add after installing.
Everything visitors browse, from the home page to the cart.
The small things that make a translated site feel native.
You have four realistic choices on Website Builder: one.com's duplicate-page method, a free browser-translation widget, a translation service that serves language subdomains, or SiteTran. Here's what each one involves.
| Duplicate pagesone.com's built-in method | Free translate widgetFor example GTranslate Free | Subdomain servicesFor example Weglot or ConveyThis | SiteTranOne Code component | |
|---|---|---|---|---|
| How it works | A home page per language with copies of your pages beneath it, translated by hand. | A script in a Code component machine-translates each page in the visitor's browser. | A script in a Code component plus DNS records. Translated pages are served from language subdomains. | SiteTran translates your pages as they render and adds a language dropdown. |
| one.com plan | Any plan with enough pages. Basic publishes 1 page, Starter 5. | A plan with Embed custom code. | A plan with Embed custom code. | A plan with Embed custom code. |
| Online Shop | The All products grid can only be used once, so the full shop stays in one language. | Machine translated on the fly, with no way to correct it. | Varies by service. | Any shop text shown on your pages, in every language you add. |
| Editing translations | You type every translation in the editor. | Not possible on the free version; translations aren't stored. | In the service's dashboard. | Translators and reviewers per language, approval, Glossary and Translation Rules, with unlimited teammates. |
| Machine translation | None built in. | Automatic, all languages, no review. | A word allowance per plan, often with a language cap. Weglot Starter: 1 language, 10,000 words. | DeepL, Google Translate and OpenAI. 7K machine translations on the Free plan. |
| Language URLs | Each copy has its own page address, such as a folder named “en”. | None. URLs don't change and search engines don't index the translations. | Language subdomains with hreflang, set up in your DNS. | Same URL by default, with translated meta tags. Language subdomains are an advanced setup. |
one.com details are from one.com's Website Builder help center. Service details are from each provider's own pricing page; none of them publishes a one.com-specific guide. All checked October 20, 2026. The duplicate-page method is a fine choice for a small brochure site with one extra language that rarely changes.
Start with machine translation and refine it with your own team. You decide what gets approved and when it goes live on your one.com site.
Get suggestions for any phrase, or translate new phrases automatically. You choose whether they're approved automatically or reviewed first.
Invite a Swedish-speaking colleague, a German partner shop or a professional translator for each language, and choose who can approve. Turn on AI Translation Review for a second opinion.
Keep product and place names consistent in the Glossary, set Translation Rules that AI translation follows, such as formal or informal tone, and reuse past work with Similar Phrases.
Choose from three dropdown types, with or without flags, and add your own CSS. Visitors are switched to their browser language automatically.
Here's what's translated as soon as you install SiteTran, and what it takes to give each language its own indexable address.
SiteTran translates more than visible text. When a visitor switches language, the page titles and meta descriptions you set in each page's SEO settings switch with it.
lang attribute, which Website Builder sets from your Page language, updated to the selected languageBy default, every language uses your existing one.com URL and the visitor's choice is remembered. For a separate, indexable page per language, SiteTran's Static Translation API returns translated HTML for an address you serve it from:
Website Builder publishes your site for you, so a language subdomain is set up in your domain's DNS settings and pointed at a small proxy or edge worker that calls the API. We'll help you plan it.
