Plan My Multilingual Setup

One Business, Many Audiences

India is one of the most linguistically diverse markets in the world. Many customers prefer to read and search in Hindi, Marathi, Tamil, Telugu, Bengali, Gujarati, Kannada, Malayalam, Punjabi and other languages, and a growing share of internet users are more comfortable in their own language than in English. At the same time, many Indian businesses export goods, offer services to clients abroad, or serve the Indian diaspora in other countries. In both cases, a single English website may leave large audiences underserved.

Creating language or country versions of a website brings technical challenges. Search engines need to understand which pages are equivalent versions of each other, which language and region each version targets, and which version to show to each searcher. Without the right setup, the English page may outrank the Hindi page for Hindi searches, country versions may be treated as duplicates of each other, visitors may land on the wrong version, and automatic redirects may prevent search engines from seeing some versions at all.

ViV Softech Solution is a website designing and digital marketing agency based in Delhi. We plan and implement the technical foundations of multilingual and international websites for businesses across India. This page explains when separate versions make sense, how to choose a URL structure, how hreflang works and the mistakes we commonly fix, how to handle language selection and redirects, translation and localisation quality, considerations for Indian languages, implementation on WordPress, our process and what affects cost. This page covers the technical setup; content translation and market-specific marketing are separate pieces of work.

What a Sound Setup Includes

Clear URL Structure

Each language or country version has its own distinct, consistent URLs.

Correct Hreflang

Annotations link equivalent pages and tell search engines which audience each targets.

Self-Referencing Canonicals

Each version canonicalises to itself, not to the English page.

Crawlable Versions

No forced redirects that stop search engines or visitors reaching other versions.

Quality Localisation

Natural translations with localised titles, descriptions, currencies and contact details.

Easy Switching

A visible language or country selector that links to the equivalent page.

Do You Need Separate Versions?

Before building anything, it is worth confirming that separate versions are justified. Language versions make sense when a meaningful share of your customers search and prefer to read in that language and when you can maintain good-quality content and respond to enquiries in it. Country versions make sense when products, prices, currencies, shipping, regulations, contact details or offers genuinely differ between markets. If the only difference would be swapping a city or country name, separate versions may be unnecessary and can create thin, near-duplicate pages. In some cases, a single English site with a dedicated section for an international audience or a few key pages in regional languages is a better starting point than translating everything. We help you weigh audience demand, maintenance effort and business goals before committing to a structure.

Choosing a URL Structure

Subfolders

For example yourdomain.com/hi/ or yourdomain.com/uk/. Easiest to manage on one domain, inherits the main site’s existing authority, and works well with most CMS multilingual plugins. Our usual recommendation for most businesses.

Subdomains

For example hi.yourdomain.com. Allows separate hosting or teams, but is often treated more like a separate site and needs more effort to build visibility. Useful when versions are run quite independently.

Country domains

For example yourbrand.co.uk or yourbrand.ae. Strongest signal for a specific country and can build local trust, but each domain must be bought, maintained and built up separately. Suits larger businesses with dedicated teams per market.

URL parameters such as ?lang=hi are generally not recommended, because they are harder for search engines and visitors to interpret. Whatever structure is chosen, it should be applied consistently, and the language or region should never be determined only by cookies or browser settings, because search engines need separate URLs to index each version.

How Hreflang Works

Hreflang annotations tell search engines that a set of pages are equivalent versions for different languages or regions. Each page lists all versions, including itself, using language codes in ISO 639-1 format, such as en for English or hi for Hindi, optionally followed by a region code in ISO 3166-1 format, such as en-IN for English in India or en-GB for English in the United Kingdom. An x-default value can indicate the fallback page for visitors whose language or region does not match any version, often a language selector or the main English page.

Hreflang can be added in three ways: link elements in the page head, HTTP headers for non-HTML files such as PDFs, or entries in the XML sitemap. The head method is most common on WordPress sites; the sitemap method suits very large sites where adding many tags to each page is impractical. Hreflang is a signal used by Google and some other search engines, while others rely more on content language and other cues, so clear language content and structure remain important.

Hreflang Mistakes We Commonly Fix

Missing return links: page A references page B, but page B does not reference page A, so search engines may ignore the annotation.
Invalid codes: using country codes as languages, such as in for India instead of hi or en-IN, or invented codes such as en-UK instead of en-GB.
Pointing to non-canonical, redirected or noindexed URLs.
All versions canonicalised to English, which conflicts with hreflang and can remove other versions from search.
Linking to the home page of each version instead of the equivalent page.
Missing self-reference in the set of annotations.
Inconsistent annotations between page tags and sitemaps.
Annotations left on pages that have no translated equivalent, pointing to irrelevant content.

We validate hreflang with crawlers that check return links and codes across the whole site, and monitor how search engines index each version.

Language Selection and Redirects

It is tempting to automatically redirect visitors to a version based on their IP location or browser language. This often causes problems: search engine crawlers mostly crawl from particular locations, so automatic redirects can stop them from ever seeing some versions; travellers, expatriates and people using VPNs are sent to the wrong version; and visitors who prefer English despite a Hindi browser setting, or the reverse, are frustrated. A better approach is to let visitors land on the version they clicked, and offer a clear, non-intrusive suggestion such as a banner that says a version in their language is available. A visible language or country selector in the header or footer, linking to the equivalent page rather than the home page, should always be available, and the visitor’s choice can be remembered for future visits.

Translation and Localisation Quality

Technical setup cannot compensate for poor content. Machine translation published without review often reads awkwardly, uses unnatural terms and may misrepresent your services, which damages trust and can be seen as low-quality content. Translations should be reviewed by fluent speakers who understand your industry. Keyword research should be done separately for each language, because people often search with different terms, mixtures of English and their language, or transliterated words written in Latin script rather than translating English phrases directly.

Localisation also covers titles, meta descriptions, image alt text, URLs where appropriate, structured data, currency and price formats, date and number formats, phone numbers with country codes, addresses, legal and policy pages, and payment and shipping information. For country versions, any regulatory or compliance requirements in each market should be confirmed with qualified local advisers. Forms and enquiry handling should be ready to respond in each language you offer.

Considerations for Indian Languages

Fonts and Rendering

Devanagari and other Indic scripts need suitable web fonts, line heights and sizes to display correctly on all devices.

Search Behaviour

Users may type in native script, transliterated Latin script or a mix with English, and voice search is common.

URLs and Slugs

Native-script URLs work but appear encoded when shared; transliterated slugs are often more practical.

For businesses serving several states, we help prioritise languages by customer demand rather than translating into every language at once, and we use region codes such as hi-IN or ta-IN only where they add meaning.

Implementation on WordPress

On WordPress, multilingual plugins manage language versions, URL structures, language switchers and hreflang tags. Each has different approaches to storing translations, handling URLs and integrating with SEO plugins, themes and page builders. We help choose a suitable plugin for your needs, configure URL structure and hreflang, make sure SEO plugin settings such as titles, canonicals and sitemaps work correctly per language, and confirm compatibility with your theme and forms. Plugins that only translate content on the fly in the browser, without creating separate indexable URLs, generally do not provide SEO benefits for other languages. For very large or complex setups, separate WordPress installations or a multisite network may be more appropriate, and we discuss the trade-offs. If you are building a new multilingual website, our website designing team can plan the language structure from the start.
