Website Localisation: Why It’s Not Just Translation

Planning to bring your website to the Czech market and wondering whether “translation” covers what you actually need? For most websites, it doesn’t. Translation converts your text. Localisation adapts the whole experience — content, SEO, formats, and technical details — so the site feels native to a Czech visitor instead of obviously foreign. This guide explains where the two diverge and what actually goes into localising a website properly.

For everything else our written translation service covers, see the main service page.

• Translation converts text; localisation adapts content, SEO, and technical details for the target market.
• Meta titles, descriptions, and slugs need their own keyword research in the target language, not a direct translation.
• hreflang tags and formatting details (dates, currency, string length) matter as much as the words themselves.
• Machine-translated website content is increasingly penalised by search engines, not just by human readers.

This distinction matters more than it sounds, because treating localisation as “translation plus a bit of polish” is where most website projects fall short.

Translation converts your existing text from one language to another, preserving structure and meaning as closely as possible. Localisation goes further: it adapts examples, imagery, tone, and even colour choices to match what resonates with a Czech audience, alongside the technical and SEO work needed for the site to actually perform in that market. Studies on content localisation consistently show it drives meaningfully higher engagement than straight translation — because it reads as written for the visitor, not translated at them.

This is the part that gets missed even by teams who know they need localisation, not just translation.

Title tags, meta descriptions, headings, alt text, and URL slugs all need their own keyword research in the target language — not a direct translation of the English original. A meta description that converts well in English will often miss the exact phrasing Czech users actually search for, because search behaviour and terminology don’t map one-to-one across languages. Getting this layer right is what determines whether your localised pages can rank at all, not just whether they read well.

Beyond words and keywords, a handful of technical details determine whether the localised site actually works as intended.

hreflang tags tell search engines which language or regional version of a page to serve to which users — done correctly, they prevent duplicate-content issues and stop visitors from landing on the wrong language version. Beyond hreflang, localisation involves adapting date and currency formats, units of measurement, and payment method displays to Czech conventions, along with checking string length — Czech text often runs longer than English, which can break layouts that weren’t built with that in mind. Most sites handle multiple languages through subdirectories (e.g. /en/, /cs/), which also tends to work better for SEO than country-code domains for smaller multilingual sites.

For website content specifically, this is where the stakes are higher than people expect.

Machine-translated content increasingly carries a real SEO cost, not just a quality one: shallow or obviously machine-translated pages are penalised by modern search ranking systems, and localisation quality itself has become a ranking signal rather than a nice-to-have. Beyond the SEO risk, machine translation on its own tends to produce recognisable artifacts — slightly-off phrasing, cultural mismatches, and layout breakage from text that doesn’t fit its container — all things a native reviewer catches before publication, not after.

Once you know what localisation actually involves, the practical side is straightforward to plan for.

We typically ask for access to the content itself — not screenshots — along with a list of priority pages, any existing glossary or tone guidelines, and the target markets you’re localising for. A typical marketing website takes a matter of weeks rather than days, and for sites that update regularly, a framework agreement covers ongoing changes without renegotiating terms for every update.

We handle the content, the SEO layer, and the technical details — not just the translation.
