Research the Keywords in Each Language

Each language and culture has unique search habits. What works in one language might be ineffective in another. A phrase commonly searched in English could have a very different popular equivalent in Spanish or Japanese.

Cultural nuances play a significant role. Some words or phrases might translate differently or might carry different connotations. It’s essential to understand this to avoid misunderstandings or misinterpretations.

People in different regions use search engines differently. Trending keywords can vary from one place to another. Keep up with these trends so your SEO strategy aligns with what people are searching for.

Competition for keywords can vary by language. A keyword might be highly competitive in English but less in another language. So you can find a chance for better ranking.

Search engines may operate differently in various languages and regions. Google might prioritize certain types of content in one language over another. Other search engines might be more popular than Google in certain countries. 

Use Specific URLs

Using specific URLs for each language is a way to avoid issues with duplicate content. Search engines recognize different language versions under unique URLs as distinct and intended for different audiences.

Users can immediately identify the language of the content from the URL. They’ll land on the correct language version that matches their search and preference​​.

URL Slugs Translation

Translating URL slugs for each page makes the site more user-friendly. This is also great for SEO, especially in local markets. Search engines prefer URLs that match the search terms. So, if your URL slugs are in the same language as the queries, your site is more likely to appear in search results.

Translated slugs make it clear what language the content on the page is in. This helps not only users but also search engines. People who see a URL in their language are likelier to click on it. This can lead to higher click-through rates. It shows that you’re translating your content and tailoring it to fit different languages and cultures. 

Use URL Language Indicators

Here are the different ways to use URL language indicators:

Country Code Top-Level Domains

These are URLs specific to a country, like .fr for France or .jp for Japan. This is useful when you have a strong presence in a particular country and want to target that audience directly. It’s beneficial for local SEO.

Subdomains with Language Codes

Create language-specific subdomains, such as for Spanish, when you want to separate your website’s content by language while maintaining a single root domain. 

Subdirectories with Language Codes

It involves creating subdirectories or folders in your URL, like for France. This method is easier to set than previous ones and is beneficial for consolidating domain authority.

Choosing the right URL structure ensures your site is user-friendly and that search engines can correctly index and rank your content in different languages. 

Hreflang Tags

Using hreflang tags is a crucial aspect of SEO optimization. These tags tell search engines which language you use on a specific page. Here’s how to use them effectively:

Specify the Language and Region 

For example, en for English, en-GB for English in the United Kingdom, es for Spanish, and es-MX for Spanish in Mexico.

Implement Tags on Each Page

Place the hreflang tags on every page of your multilingual site. This includes every version of each page in different languages. The tag should be placed in the <head> section of HTML.

Use Self-referential Tags

On each page, include an hreflang tag that refers to that page itself and tags for other language versions. For example, on the Spanish version of a page, have an es hreflang tag pointing to that same Spanish page.

Include a Default Language Tag

Use an x-default hreflang tag to indicate a default language. This is useful when the user’s language is unavailable on your site. The x-default tag points to a page you’d like to show users when their language preference is unavailable.

Ensure Consistency Across Pages

Each language version of a page should include the same set of hreflang tags, pointing to all other language versions of that page, including itself. 

Avoid Common Mistakes 

Ensure that each URL in your hreflang tags is fully specified and accessible, not blocked by robots.txt or noindex tags.

Validate Your Tags

Use tools like Google Search Console to validate your hreflang tags. These tools can help identify incorrect language codes or missing return links.

Update Tags as Your Site Evolve

Whenever you add new languages or change page URLs, update your hreflang tags accordingly. 

Don’t Mix Different Languages on the Same Page

Imagine you’re visiting a website, and it’s in two or more languages on the same page. It can be not very clear. That’s why it’s essential to keep things straightforward.

Search engines prefer when you stick to one language per page. Mixing languages can potentially hurt your website’s visibility.

Write Metadata for Each Language

Writing metadata for each language impacts how your site performs in search results. You’re telling search engines that your content is relevant to users in those languages. It is part of a localization process. Major search engines recommend using metadata in the same language as the content. 

Create Multilingual Sitemaps

Sitemaps help search engines understand your website’s structure and content in different languages. It makes it easier for them to index your pages effectively, improving your search engine rankings. Navigation will be smoother. No one likes to stumble upon content in a language they don’t understand.

Since multilingual sites often have similar content in different languages, search engines must know that these duplicates are intentional translations. Sitemaps with language annotations make this clear.

It would be best if you made separate sitemaps for each language version. Use hreflang tags to specify the language and region for each page. Then, submit these sitemaps to search engines through their webmaster tools.

Remember to keep your sitemaps updated whenever you add new pages or make changes. This ensures that your multilingual website remains well-indexed, language-targeted, and user-friendly.

Translate the “Hidden” Parts of Your Website

Don’t forget to translate parts of the site that are not visible. Alt text, checkout, contact pages, newsletter sign-up forms, and error messages are those. 

Translating alt text for images is about inclusivity and accessibility. You allow users with disabilities to understand the content of images.

Checkout pages often contain essential information, such as payment details and shipping options. Translating them instills trust in users and reduces the risk of confusion.

Contact pages serve as a direct line of communication between you and your users. Newsletter sign-up forms are a great way to expand your audience, but they must be in the user’s language to be effective.

When errors occur, users must understand what went wrong and how to fix it. Translating error messages ensures that users can comprehend and resolve issues without frustration.

Translating all these elements demonstrates your commitment to providing a fully localized and user-friendly experience.

Have a Language Selector on a Visible Place

Users should quickly identify and switch to their preferred language when visiting your website. It demonstrates your commitment to serving a diverse audience and will impact the success of your multilingual website.
