The 50-Point Polish Website Localisation Checklist

Direct answer

What should you know first?

Translate the customer journey, not a spreadsheet of isolated strings. Navigation, forms, errors, checkout, email and support must use one terminology system.
Polish localisation changes grammar, address forms, currencies, dates, search queries and sometimes interface length.
Use pl-PL locale handling, correct Polish characters, local search research and a page-level language signal.
Test the complete purchase or lead journey on mobile with realistic Polish data before launch.
Score all 50 checks, but block launch when a legal, payment, privacy, consent or critical-action check fails.

How to use it

How should you score the 50-point Polish localisation checklist?

Give each check 0 for missing, 1 for partial and 2 for complete. The maximum score is 100, but the total cannot override a critical failure in checkout, consent, pricing, privacy or a binding customer action.

Polish website localisation readiness bands
Score	Readiness	Action
90 to 100	Launch-ready with minor observations	Document owners and monitor real-user feedback
75 to 89	Usable but exposed	Fix high-impact gaps before paid traffic
50 to 74	Partial localisation	Run a focused language and journey sprint
0 to 49	Translated fragments, not a localised site	Re-scope the project around complete journeys

Decision: A 96-point score still fails if the order button, cancellation right or consent message is wrong. Use both the score and critical blockers.

Ownership

Who should own each localisation workstream?

Five-workstream ownership model
Workstream	Primary owner	Reviewer	Launch evidence
Language and terminology	Polish translator or localisation lead	Product or marketing owner	Approved termbase and query log
UX and interface	Product or web team	Polish linguist and accessibility reviewer	In-context screenshots and test record
SEO	SEO lead	Polish search specialist	Keyword map and crawl
Commerce and legal	Commercial owner	Qualified legal reviewer where needed	Approved customer journey
Release QA	Project manager	Cross-functional sign-off group	Blocker log at zero

Decision: One person can hold several roles on a small site, but every decision still needs a named owner and review point.

Buyer questions

Frequently asked questions

What is the difference between Polish website translation and localisation?

Translation changes the language. Localisation also adapts search intent, interface behaviour, formats, payments, legal information and the complete customer journey for Poland.

Should Polish pages use a .pl domain?

Not always. A country-code domain can send a strong market signal, while a /pl/ folder can be easier to manage. Choose one architecture and implement language signals consistently.

Do I need hreflang for English and Polish pages?

Use hreflang when equivalent pages target different languages or locales. Each page should reference itself and its valid equivalents.

Can AI translate all website strings?

AI can accelerate a draft, but strings still need context, terminology, placeholder, length, legal and in-interface checks by people who understand Polish and the product.

How long should Polish sentences be?

There is no universal limit, but Polish public-sector plain-language guidance recommends short sentences, often around 15 to 20 words, when clarity allows.

What should block a Polish website launch?

Block launch for wrong prices, broken payment, unclear consent, missing consumer information, unsafe instructions, inaccessible critical actions or untranslated customer communications.
