AI content localisation: Reaching UK regional audiences

What to take away

Translation is not the same as localisation

Machine translation converts text from one language into another. Localisation goes further: it changes examples, spellings, measurements, currency and search phrasing so the page reads as if it was written for that audience. A Welsh-language page may need a different order of information, not just a Welsh version of an English draft.

The discipline predates software, as the outline of localisation on Wikipedia shows, and its central idea is fitting a product to a place rather than swapping its words.

Where England, Scotland, Wales and Northern Ireland diverge

Scots law uses its own terms for property, court and inheritance matters, so a page about rented housing cannot be reused unchanged north of the border. For example, a Scottish property purchase may be concluded by missives; ownership is recorded in the Land Register of Scotland, and an executor may need confirmation from the sheriff court in an estate. Have a reviewer familiar with Scots law check legal content.

Northern Ireland has its own planning, education and health terminology. For planning, check the Department for Infrastructure's guidance; for education, the Education Authority; and for health, Health and Social Care (HSC) materials in Northern Ireland. Use these as terminology references and verify terms against the service being described.

England is not uniform either. A Bristol page and a Newcastle page can share a spellchecker and still need different examples, because transport, housing and council services vary by area.

For example, a generic line such as “Find council housing support near you” could become “Find council housing support in Bristol” or “Find council housing support in Newcastle”. Use a named place only when the page genuinely serves it; the wording alone does not establish service coverage.

The GOV.UK style guide is a sound reference for plain English and for keeping terminology consistent across a set of regional pages.

Local SEO signals for regional pages

Each region page needs its own URL, title, meta description and internal links. Copying one English page onto four regional URLs creates near-duplicates that compete with each other in search results.

A single brief stops four writers producing four tones. Our AI content brief template keeps the fields identical, so only examples, keywords and proof points change per region.

Structured data can help as well: use Schema.org's areaServed property to identify the locations a business serves, where appropriate. Keep the business name, address and phone number consistent for the same location across the site.

A workflow for regional rollouts

Keep the prompts for each region in one place. Reviewers need to see what the model was asked to do before they approve the output, and a shared AI content prompt library turns that audit trail into routine practice.

Machine-translation and localisation tools such as DeepL, Lokalise, Phrase, Crowdin, Smartling and Weglot can support parts of the workflow; check their current features and data-handling terms before selecting one. They do not replace the regional reviewer or legal check.

How to measure regional performance

Report each region separately in analytics. Average position hides the differences that matter, such as which region converts on a service page and which one leaves.

Watch branded search terms for regional spellings and place names. Those queries show whether the localised wording matches how people actually search.

Data, language duties and review

If customer reviews or support tickets go into a model to learn local phrasing, that counts as personal data processing. The ICO's UK GDPR guidance sets out lawful bases, retention limits and the rights people hold over text you reuse.

Welsh language duties are not a blanket requirement on every private firm. The Welsh Language (Wales) Measure 2011 provides for Welsh Language Standards; the Welsh Language Commissioner oversees compliance with standards that apply to organisations within scope. Confirm which standards cover your organisation before promising bilingual delivery.

The Equality Act 2010 public sector equality duty applies to relevant public authorities in Great Britain; in Northern Ireland, the public sector equality duty arises under section 75 of the Northern Ireland Act 1998. These duties do not mean every page must be translated, but they belong in the compliance review where applicable.

Common questions

Does localisation always mean translating into Welsh or Scots Gaelic?

Not by default. Scots and Scottish Gaelic (Gàidhlig) are distinct languages; localisation may stay in English, use Scots where it fits the audience, or need a Gaelic version. The Gaelic Language (Scotland) Act 2005 established Bòrd na Gàidhlig and allows it to require relevant public authorities to prepare Gaelic language plans, so it is not a blanket translation duty on every organisation.

How much can AI handle before a human steps in?

AI is useful for drafting variants, swapping examples and writing meta descriptions at scale. It is weak on statutory terms and slang, so a regional reviewer should approve the final text.

Do I need one page per UK region?

Only where the reader's need, the service or the legal context differs. Where it does not, one clear page covering your service area beats four near-duplicate regional pages.
