What is multilingual SEO?
Multilingual SEO is the process of optimizing your website content for multiple languages and regions — in a way that search engines can understand, index, and rank.
-
Translations ≠ SEO
-
Keyword research must be localized, not translated
-
Metadata, alt text, site structure — all must support multilingual indexing
Multilingual SEO involves:
-
Local search behavior analysis
-
Technical optimization (e.g., hreflang, site architecture)
-
Monitoring performance per language and region
Expert Insight – Hinde Lamrani, Digital Marketing Services Director, Acolad
“When your target audience is global, having search‑optimized digital content becomes even more pressing to ensure visibility in different markets.”
Why is multilingual SEO important?
75% of users never scroll past the first page of Google
90% of users prefer to browse in their native language (CSA Research)
With multilingual SEO, you can:
-
Rank on local SERPs and AI-generated answers
-
Reach users in their native language
-
Increase organic traffic, conversions and brand trust
-
Optimize ROI across all content and localization efforts
How to Build a High-Impact Multilingual SEO Strategy
1. Define your target markets
Before optimizing for international SEO, clearly identify which countries and languages represent real business opportunities. This requires analyzing:
-
Existing traffic by country and language (via Google Analytics & GSC)
-
Markets with the highest conversion rates or strategic value
-
User behavior differences across regions
Why it matters: Each market has its own search behavior, devices, platforms, and expectations. Targeting the wrong language or country wastes resources.

2. Choose your domain structure
Your site architecture influences how search engines index and rank your localized pages. The three most common structures are:
-
ccTLD(example.fr) – best for market-specific branding but costly to scale -
Subdomain(fr.example.com) – flexible but weaker authority sharing -
Subdirectory(example.com/fr) – recommended for SEO consolidation
Tip: Whatever structure you choose, ensure consistent hreflang implementation to signal language and regional intent to Google.

3. Perform localized keyword research
Don't just translate keywords. In every market, users search differently — even for the same product.
Key actions:
-
Collaborate with native SEO experts to capture real user intent
-
Use tools like Semrush, Ahrefs, Google Keyword Planner, or Google Trends
-
Avoid literal translations — focus on intent relevance
4. Translate and localize your content
You can now begin incorporating your SEO keywords into your website! But remember — multilingual SEO requires more than surface-level translation.
It’s important to localize your entire website, including page titles, menu items, images, and internal links. A partially translated website can negatively impact your SEO rankings and user experience, especially if core metadata remains in the source language.
At Acolad, we offer a full range of translation and localization services carried out by native-speaking professional linguists. Our experts ensure that your content feels natural, relevant, and SEO-optimized for each target market — helping you increase both traffic and conversions.
Professional translations done by a native speaker are essential for high-quality, high-performing multilingual content. But it doesn’t stop at the visible text. You’ll also need to translate “invisible” content elements such as:
-
Metadata (titles, descriptions)
-
Image alt texts
-
URL slugs and internal anchor text
-
Structured data and schema markup
By optimizing these elements for each language, you ensure that your localized pages are indexable, searchable, and competitive in every local search engine result page.
At Acolad, we combine the expertise of native-speaking SEO linguists with advanced content workflows, supported by the latest language and automation technologies.
This approach enables us to deliver high-quality, scalable multilingual content optimized for both users and search engines.
