Setting up Kazakh website localization: pluralization, dates, SEO

Kazakh website localization: where logic and SEO break

Website localization into Kazakh is not about translating strings in a file. Kazakh is an agglutinative language: plurals, cases, and possessive forms are built with affixes that depend on the last syllable of the word (vowel harmony).

That is why the usual scheme of "one form for one, another for many" does not work here: "1 item," "2 items," "5 items" turn into different constructions with different endings, and pluralization logic hardcoded for Russian or English produces "5 item" or "2 items" in the Kazakh version of the site.

Next, what usually goes unchecked breaks. Date and number formats: the "day-month-year" order, names of months and days of the week, thousands separators, currency in product cards and the cart.

If date templates are pulled from a shared library without accounting for the locale, the user sees "12/03" and cannot tell whether it is March or December.

Sorting and search for Kazakh words with specific characters (ә, ғ, қ, ң, ө, ұ, ү, һ, і) fall out of place in standard string comparison — filters and alphabetical lists start to lie.

The most expensive part is SEO. A multilingual site without correct language versions loses Kazakh search results entirely: the search engine does not see the connection between pages, duplicates content, or shows the Russian version to those searching in Kazakh.

Localization errors in titles, meta descriptions, and structured data hurt rankings more than machine translation itself, because the snippet looks irrelevant.

For a business, this is not an abstraction: the Kazakh-speaking audience goes to a competitor who simply did the version correctly, while acquisition costs grow because organic traffic does not convert. Let's break down how this is addressed at the level of code, templates, and site structure.

What correct localization delivers: measurable effects

Organic traffic growth through Kazakh-language queries

The Kazakh version starts to collect organic traffic that simply did not exist before: queries in Kazakh in search have almost no competing pages, and a correctly marked-up version takes top positions faster than the Russian one in a competitive niche.

The key condition is not machine translation, but texts proofread by a native speaker and correct language attributes on pages, so that the search engine does not merge the versions into one and does not lose half of the results.

Lower bounce rate among the Kazakh-speaking audience

A user who searches in Kazakh but lands on a Russian page leaves within a few seconds — this is the main contributor to bounces. When the language of the interface, navigation, and forms matches the language of the query, the depth of viewing grows and the bounce rate falls.

We separately check pluralization, date declension, and number formats: an error in a case ending or in a numeral ending is read by a native speaker as carelessness and undermines trust in the entire site.

Fewer edits and revisions after launch

Properly built-in language support is not a one-time upload of translations, but a managed structure: dictionaries, declension rules, and date formatting are kept separate, so adding new pages or sections does not require rewriting the logic.

Native speakers stop sending lists of edits after every release, and the team spends time on product development rather than endless proofreading.

What this adds up to

The effect of localization is made up of three measurable things: the share of organic traffic grows through a new language segment, the bounce rate among the Kazakh-speaking audience falls, and the volume of edits from native speakers is reduced.

All of this works only together — translation without a technical foundation does not retain the user, and a technical foundation without proofreading does not bring traffic.

Approaches to Implementing the Kazakh Version: Comparing Options

Choosing an addressing scheme is a decision that is expensive to change after launch: it affects routing, canonical URLs, the sitemap, and all external links.

In practice, the choice comes down to three options — a subdomain, a subfolder, and a language parameter in the query string. Below is a comparison by effort, impact on search results, and limitations, so the decision is made before the first line of code, not after.

For a bilingual site with shared content, a subfolder almost always wins: one domain, one set of rules, predictable results. A subdomain is justified when the Kazakh version lives on a different stack or is maintained by a separate team.

We leave the language parameter for service scenarios — as a primary scheme it creates duplicates and hinders search.

Regardless of the choice, the versions are linked via hreflang: each page links to itself and to its language counterparts, and also specifies the default version. This removes competition between URLs and tells the search engine which version to show the user.

The structure of the multilingual site remains unified: one template, one set of components, different dictionaries and date formats.

We fix the localization method at the start and build it into the routes, the sitemap, and the templates — then adding a third language comes down to a new folder and dictionary, rather than rewriting the navigation.

Implementing Kazakh localization: stages of engineering work

Localization is not translating strings in a file, but changing the behavior of the application: formats, declensions, routes, metadata.

Below is the order of work that we go through on every project so that the Kazakh version does not diverge from the Russian one at the very first release.

1. Internationalization audit. We look at how strings get into the interface: hardcoded in templates, assembled in code, or already extracted into catalogs. We check whether there is end-to-end language propagation through routes and sessions, how language switchers and redirects are structured, and whether the selected locale is lost when navigating between sections.
2. Translation schema. We fix the structure of catalogs by language with an identical set of keys so that a missing string in the Kazakh version is detected by the build rather than by the user. We agree on rules for naming keys and on what goes into translation and what remains a constant.
3. Pluralization and formats. We configure plural rules for Kazakh — the categories differ from Russian ones, and a mechanical transfer breaks the agreement of numerals with nouns. Separately, we set the formats of dates, times, numbers, and currency so that they are not inherited from the browser's system locale.
4. SEO layer of localization. We set the language attributes of pages, canonical and cross-links between versions, and translate metadata and titles. Without this, search engines merge the versions and show the Russian page to a Kazakh-speaking user.
5. Localization check. We run the interface on long Kazakh strings — they are noticeably wider than Russian ones and break the layout of buttons and tables. We verify declensions in dynamic messages, emails, and notifications, and check sorting and search taking into account specific characters.
6. Handover and support. We hand over the translation catalogs, pluralization rules, and instructions on how to add a new string so that the client's team does not wait for us on every edit. After that, new texts go through the same control at build time.

This order eliminates the class of errors where the Kazakh version formally exists but shows Russian dates, incorrect endings, or drops out of search.

What we hand over: configurations, glossary, regulations

Localization is not "translated the strings and forgot about it," but a set of artifacts that the client's team can use to keep working without us. We hand over everything needed to independently update content and connect new languages.

• Translation files — structured string catalogs with keys and a breakdown by site sections, in a format that is readable by both an editor and the build system. No translations "hardcoded" into templates: everything is moved out into separate resources.
• Terminology glossary — an agreed-upon list of industry concepts, service names, and brand wording, indicating what gets translated and what stays in Latin script. It eliminates the main cause of discrepancies: when "delivery" sounds different on one page than on another.
• Pluralization rules — described plural forms for Kazakh and Russian with examples and tied to product and service categories. We separately record which numeric ranges correspond to which form.
• Format settings — rules for outputting dates, times, numbers, thousands separators, and currency, tied to the locale rather than to the visitor's browser. This eliminates situations where the date on a card and in an email look different.
• Localization documentation — a map of language-to-section correspondence, a scheme for connecting a new translation, and a description of where strings are stored and how they reach the page.
• Update regulations — the procedure for editing text: who changes the source string, how validation is triggered, and what happens to old translations. Plus a pre-publication checklist: untranslated keys, broken placeholders, and correct inflections.

Together, this provides a predictable cycle: new text appears identically in all languages, rather than "somewhere in Kazakh, somewhere in Russian." If you already have translations in another format, we will migrate them into this structure and reconcile them with the glossary.

Case study: how Kazakh localization eliminated errors in dates and grammatical cases

The client — a delivery service with a catalog of several thousand items — came with a classic picture: the Kazakh version of the site existed, but lived on manual edits.

Numerals were inserted into the template without agreement, and instead of correct forms, cards and checkout showed truncated forms like "3 товар" or "5 товаров" where the language requires its own form for each number.

Dates were displayed in the same format for both versions, months were not declined, and the "day-month-year" order did not match what the reader was used to.

First, our engineers separated the locales at the data level rather than the template level: strings were moved into dictionaries with separate rules for each language, and numeral forms were extracted into a separate function with a set of categories — one, few, many.

This is automatic pluralization: the template no longer decides which form to insert; it requests it from the rule based on the number. Month declension and the correct date format were added there too, so that the output no longer depended on who edited the markup and when.

A separate piece of work — search results. For the Kazakh version, we wrote dedicated titles, descriptions, and page URLs, and linked the language versions to each other so that the search engine would understand: these are not duplicates, but translations of the same catalog. Previously these pages competed with each other; now each one answers its own query.

Yandex and other search engines pulled the Kazakh pages into the index, and the share of the Kazakh version in total traffic grew from 6% to 23% over the quarter.

Errors in grammatical cases and numeral forms at checkout — zero, manual string edits stopped: texts are changed in a single dictionary and immediately visible in both versions.

Localization metrics are now captured automatically — by the share of pages with a complete translation and by the number of support requests caused by incorrect text, and the latter dropped to almost zero.

How does pluralization in Kazakh differ from Russian?

In Russian, the rule is simple: the form depends on the last digits of the number — 1 book, 2 books, 5 books. In Kazakh, after a numeral the noun always stands in the singular: "бір кітап", "екі кітап", "бес кітап".

The plural is used only when it is important to emphasize separateness or an indefinite multitude — "кітаптар" as "books in general". This is not an exception to the rules, but a different logic of counting, and it breaks the usual patterns.

Hence the main mistake in localization: a developer transfers Russian plural categories (one / few / many) onto Kazakh and gets "2 кітаптар" instead of "2 кітап".

To the client this looks like a minor typo, but a native speaker reads such a line as machine translation — trust in the interface drops on the very first screen with a number.

Implementing pluralization in code is built not on copying the Russian scheme, but on a separate set of rules for Kazakh: there is one category — "other", and it applies to all numbers without analyzing the last digits.

We move the agreement forms into translation files rather than hardcoding them into templates, so that edits don't require a rebuild.

We separately check the places where a number is glued to a word: product counters, notification counters, "N results", pagination, delivery times.

There is also the reverse case — when Kazakh requires the plural while Russian gets by with the singular. Such strings cannot be derived by a formula; they are agreed upon by a native-speaker translator, and the engineer fixes them as a separate key. That is why we run texts through a native-speaker review before release, not after user complaints.

In practice, website localization into Kazakh is not translating strings, but rebuilding the agreement rules for a different grammar. If you leave the Russian scheme in place, the interface will be formally "in Kazakh", but will read as foreign.

Technical localization concerns: answering frequent questions

Localization rarely starts from a clean slate: usually there is already a working site, accumulated search history, and content that someone maintains.

This is where the main technical concerns come from — whether to translate everything at once or in stages, what to do with an already deployed version, and how not to lose rankings. Let's break down each question in detail.

Whether the entire site needs to be translated at once. No, and this is a deliberate engineering decision. We prioritize pages: first the core — home page, key services, contacts — then the catalog and blog.

Each stage is released as a separate deployment so that indexing and behavior can be checked before moving on to the next block. Staged translation provides a manageable scope of edits instead of one large deployment where errors are searched for blindly.

What to do with an already deployed version. We do not rewrite an existing localized version from scratch — we take stock of its current state: which URLs are indexed, which redirects are configured, where templates diverge.

Then we work on top of it: we preserve working URLs, add missing language links, and fix what prevents correct indexing. This way, the effort already invested is not lost.

How not to lose rankings. The key is not to change URLs without redirects and not to create duplicates. We maintain canonical URLs, language tags, and a redirect map so that the search engine sees continuity rather than a new site.

Rankings for the primary language remain untouched — localization adds visibility rather than replacing it.

What happens if some pages remain untranslated?

Nothing critical — untranslated URLs continue to work in the primary language. It is only important to correctly link them with the localized versions so that the search engine does not consider them duplicates. We mark such pages and close the links as translation progresses.

Let's discuss your website localization task

To make the localization estimate concrete rather than a rough guess, we need input data: the current website structure and language versions, where the content comes from (an editor, an external system, translation files), and which sections are critical for the Kazakh version first.

Separately, we clarify the SEO requirements — whether separate URLs are needed for each language, how the versions are planned to be linked to each other, and who is responsible for translations and proofreading.

Based on this data, we put together a work plan: which strings we move into dictionaries, where pluralization and form agreement are needed, how we configure date, number, and currency formats for Kazakh, and what we do with meta tags, the sitemap, and language switchers.

We break the plan into stages with a clear result at each one — from auditing the current localization to checking the finished Kazakh version.

To come back with an estimate, describe the task and attach:

• the website address and a list of current language versions;
• where the content comes from and who prepares the translations;
• which sections and pages should appear in Kazakh first;
• SEO requirements: separate URLs, meta tags, sitemap;
• whether there are dynamic elements — forms, a user account, notifications;
• constraints on timelines and the order in which the version is rolled out to production;
• who on the client side accepts the result and checks the texts.

After that, we will come back with an estimate, a work plan, and the team composition for your task. Let's discuss the website localization task — we will show how the Kazakh version fits into the current structure without reworking the entire website.
