Case Study: How Translation Boosted Our Client’s International SEO by 80%

In today’s global marketplace, expanding your digital presence beyond borders is essential for business growth. But did you know that professional translation and localization can significantly impact your international SEO? At Idiomatic Brasil, we recently helped a client achieve an impressive 80% boost in their international SEO performance — and in this case study, we’ll show you how.

Background: The Challenge Our Client Faced

Our client, a mid-sized e-commerce company based in Brazil, wanted to expand into Portuguese-speaking markets worldwide, including Portugal and parts of Africa, as well as Spanish-speaking countries in Latin America. Despite having a multilingual website, their international traffic and rankings remained stagnant.

Key challenges included:

• Poorly translated content that sounded “machine-generated”
  
  

• Lack of localized keywords relevant to target countries
  
  

• Duplicate content issues across language versions
  
  

• Missing hreflang tags and inconsistent URL structures
  
  

Our Strategy: Translation + SEO Localization

We implemented a comprehensive plan focusing on quality translation integrated with SEO best practices:

1. Human Translation by Native Speakers

Instead of using machine translation, we provided professional translators native to target countries to ensure natural, culturally relevant content.

2. Localized Keyword Research

We conducted in-depth keyword research for each target market, adjusting keywords to local dialects and search behavior — for example, “tênis” in Brazil vs. “sapatilhas” in Portugal.

3. Content Optimization

We optimized meta titles, descriptions, headers, and alt tags with localized keywords for better search engine visibility.

4. Technical SEO Support

We helped implement hreflang tags to avoid duplicate content penalties and to direct users to the right language version.

Results: An 80% Increase in International SEO Performance

Within 6 months of launching the newly localized site, our client saw:

• 80% increase in organic traffic from target countries
  
  

• Significant ranking improvements for localized keywords
  
  

• Higher engagement rates and lower bounce rates on translated pages
  
  

• Increased online sales and inquiries from international customers
  
  

Why Professional Translation Makes the Difference

Our case study demonstrates that translation isn’t just about converting words — it’s about adapting content to fit cultural and linguistic nuances. This builds trust with your audience and improves your website’s authority and relevance in local search results.
