Multilingual website planning: How can essential content be chosen when adding a second language for the first time?

When a website adds a second language for the first time, the most common mistake is trying to translate everything at once. A full-site translation is expensive, slow to maintain, and often unnecessary. A more practical starting point is to ask which pages or sections a visitor in the new language actually needs to complete an action — making a purchase, submitting an inquiry, understanding a service, or finding contact details. Those are the pages to translate first.

One way to identify that core set is to look at which existing pages already attract the most visits or generate the most questions from speakers of the target language. If the site already receives traffic or inquiries from that audience, the pages they land on and the topics they ask about give a direct signal. If there is no existing traffic to draw from, thinking through the shortest path a new visitor would need to go from landing on the site to taking the desired step can serve as a substitute guide.

Another useful distinction is between content that supports a decision and content that provides background. Product descriptions, pricing, terms of service, and instructions help someone decide or act. Blog posts, company history, and opinion pieces are valuable but rarely block a visitor from completing a task. Translating the decision-support material first means the second-language version is functional even if it is not yet complete.

A practical concern that often gets overlooked is ongoing maintenance. Once a page is translated, any future change to the original needs a matching update in the second language. Choosing fewer pages at the start reduces this burden and makes it more realistic to keep both versions accurate over time. It is better to have ten pages that stay current than fifty pages where the translation drifts out of sync with the source.

The process does not have to be a one-time decision. A reasonable approach is to launch with the core set, then review after a few months to see what visitors in the second language actually search for, ask about, or abandon. That feedback becomes the basis for deciding which additional pages to translate next, rather than guessing upfront what the full scope should be.
