Configure Hubspot SEO language settings for multilingual content

Managing multilingual content in Hubspot requires configuring language settings in the SEO tool so topic recommendations, related subtopics, and keywords work correctly across all your languages.

This guide walks you through how language support works in the SEO tool, which features depend on language detection, and how to turn those options on or off for your content strategy.

How Hubspot SEO language support works

The SEO tool analyzes the language of your content to power multiple features. It does this in two primary ways:

Using the language set on a tracked domain when available.
Falling back to automatic language detection when no domain language is set.

Understanding this logic is important when you have multiple domains, subdomains, or language variations for the same content.

Hubspot domain language vs automatic detection

When you track a domain, the SEO tool first checks which language is associated with that domain. If a language is configured, it will use that setting to determine which SEO features are available and how content is analyzed.

If no domain language is set, the SEO tool attempts to automatically detect the language of each page it scans. This is helpful for sites that have not explicitly assigned languages but still publish localized content.

In both cases, only certain languages are supported for specific SEO features. Knowing the supported language list will help you plan your content strategy effectively.

Hubspot supported languages and SEO features

Different SEO features may only work for specific languages. This affects topic generation, subtopic suggestions, and keyword recommendations.

Hubspot topic recommendations and supported languages

Topic recommendations in the SEO tool help you discover core topics that match your content and audience. These recommendations are language-sensitive. If your content is written in a supported language, the tool can:

Suggest broad topic ideas based on your site and inputs.
Evaluate how well content clusters align to those topics.
Improve relevancy for search terms in that language.

If your content language is not supported, topic recommendations may be limited or unavailable. In that case, you may need to choose topics manually and track performance using other SEO metrics.

Hubspot related topics and subtopic suggestions

The related topics feature suggests subtopics connected to your main topic. This is crucial for building topic clusters. The system looks at the language of your content to produce relevant subtopic phrases.

When language support is available, you can:

Search for related subtopics in the same language.
Evaluate search volume and difficulty for each suggestion.
Refine which subtopics belong in a cluster.

In unsupported languages, related topic suggestions may be less accurate, so you may want to rely more on manual research and keyword tools.

Hubspot keyword suggestions and limitations

Keyword suggestions in the SEO tool rely heavily on language detection. They are more robust when your tracked domain is set to a language recognized by the system.

For supported languages, keyword suggestions can help you:

Discover new search terms based on your primary topic.
Evaluate existing keywords and their performance potential.
Refine titles, meta descriptions, and headings.

In languages that are not fully supported, keyword suggestions may not appear or may have limited data. You may need to combine the SEO tool with separate keyword research platforms when working in those languages.

Setting up your domain language in Hubspot

To get the best use of language-dependent SEO features, you should confirm that each tracked domain has the correct language assigned.

Step-by-step: configure domain language for SEO

Sign in to your Hubspot account with permissions to manage domains and the SEO tool.
Navigate to your settings and locate the section where tracked domains are configured.
Select the domain or subdomain used for your content that you want to analyze in the SEO tool.
Assign the correct language for that domain. For multilingual sites, configure languages for each regional domain or subdomain where available.
Save your changes so the SEO tool can use the domain language for future scanning and recommendations.

After saving, the SEO tool will use that domain language whenever possible instead of relying solely on automatic detection.

Managing multilingual SEO content in Hubspot

When you work with multiple languages, you may have several topic clusters or campaigns per language. The way you configure each domain and content group will affect how the SEO tool behaves.

Hubspot best practices for multilingual topic clusters

To maintain consistent SEO performance across languages, consider the following best practices:

Create separate topic clusters for each language rather than mixing languages in a single cluster.
Ensure each cluster is tied to a domain or subdomain that has the correct language setting.
Use language-appropriate keywords and subtopics that reflect real user search terms in that region.
Monitor how well each cluster performs in traffic and rankings, then refine your topics and content accordingly.

This structure helps the SEO tool correctly evaluate content relationships within each language.

When language support is limited

If the language you publish in is partially or not fully supported, you can still use the SEO tool, but you may face some limitations in automatic recommendations and keyword data.

In those cases:

Rely more on manual keyword research to define your main topics and subtopics.
Use the SEO tool primarily for technical and structural checks where language has less impact.
Track performance with analytics to validate which pages and clusters attract organic traffic in each language.

This hybrid approach allows you to extend the utility of the platform even when language features are constrained.

Checking Hubspot language feature availability

Because language support for topic recommendations, related topics, and keyword suggestions may change over time, you should periodically review the official documentation.

You can find the current list of supported languages and feature details directly in the product help center at this Hubspot SEO language settings article.

Use that reference to confirm which languages have access to specific SEO capabilities before planning major multilingual expansions.

Planning next steps for SEO with Hubspot

Once your language settings are properly configured, focus on building topic clusters, creating high-quality content, and monitoring performance for each language.

Hubspot SEO workflow for multilingual teams

A simple workflow you can follow is:

Define core topics in each language based on user intent and business goals.
Verify that each language has a dedicated domain or subdomain with the correct setting.
Use the SEO tool to structure pillar pages and subtopic content for each language.
Review topic recommendations and keyword suggestions where available, then refine your strategy.
Measure traffic, rankings, and conversions per language and adjust content clusters regularly.

With this approach, multilingual teams can coordinate around a clear plan while using the SEO tool effectively.
