The short answer
Translate service pages, calls to action, forms, errors and follow-up messages. Use separate language URLs and test language switching and the enquiry journey on real screens.
Map the customer journey
List the steps from reading a service page to submitting an enquiry. A translated homepage does little to resolve confusion if the form stays in another language.
- Main service pages and contact information.
- Menus, buttons, field labels and validation messages.
- Success messages and next-step instructions.
- Relevant downloads, policies and follow-up emails.
Adapt the message to the reader
Agree tone, service names and product terminology. A sales headline should communicate a useful benefit in the target market rather than preserve an awkward source sentence.
W3C — Localization vs. Internationalization distinguishes adapting a product for local requirements from preparing it to support such adaptation. Website language work needs coordination with implementation.
Make language versions discoverable
Google Search Central — Multilingual sites recommends separate URLs for language versions and explains how to signal their relationship. Review those arrangements alongside translated titles and page content.
For example, /vi/services/ and /services/ can represent corresponding versions. A language switch should preserve the current page when its counterpart exists.
Use region as a suggestion
Location or browser language can inform an initial suggestion, but visitors should retain control. Someone in Vietnam may prefer English, while a visitor abroad may need Vietnamese.
Define how choices are remembered and how explicit language URLs behave. Test redirects with the technical team so visitors can reach the version they intend to read.
Check before launch
Inspect headings, buttons and form fields on mobile. Follow the permitted testing process to check validation and success messages in each language.
Deliver a page inventory and implementation notes with the copy. Good content supports decisions, but translation alone does not guarantee search rankings or enquiries.
Frequently asked questions
Must every page launch at once?
You can prioritize a complete journey for a core service, then expand. Translate all required steps in that journey.
Does localization guarantee SEO results?
No. Content, crawlability, implementation and other factors all affect search performance.
