Frequently Asked Questions.


Optimizing SEO for multilingual and multi-regional websites is crucial for businesses in Brussels, given its multilingual nature and international significance. Here are key considerations and strategies for effective multilingual SEO:

1. Proper URL Structure

Use one of these URL structures for language/region targeting:

  • ccTLDs (e.g., website.be, website.fr)
  • Subdomains (e.g., fr.website.com, nl.website.com)
  • Subdirectories (e.g., website.com/fr/, website.com/nl/)
2. Hreflang Implementation

Implement hreflang tags to indicate language variations of a page. For Brussels, you might use:

  • hreflang='fr-be' for French content
  • hreflang='nl-be' for Dutch content
  • hreflang='en-be' for English content
3. Content Localization

Don't just translate; localize your content:

  • Adapt to local culture, idioms, and preferences
  • Use local keywords and search trends
  • Consider local events and holidays (e.g., Belgian National Day)
4. Keyword Research for Each Language

Conduct separate keyword research for each target language and region. In Brussels, focus on:

  • French, Dutch, and possibly English keywords
  • Local search terms and Brussels-specific phrases
5. Avoid Automatic Translation

Use professional translation services or native speakers to ensure high-quality, natural-sounding content that resonates with the local audience.

6. Separate Google Search Console Properties

Set up separate Google Search Console properties for each language version of your site to track performance and issues specific to each language.

7. Local Backlinks

Build backlinks from local Belgian and Brussels-based websites in the appropriate language to boost local SEO signals.

8. Mobile Optimization

Ensure your multilingual site is mobile-friendly, as mobile usage in Belgium is high (89.7% of the population as of 2021).

9. Site Speed Optimization

Optimize loading speeds for all language versions. According to recent data, the average page load time in Belgium is 8.8 seconds, which is slower than the recommended 3 seconds.

10. Cultural Sensitivity

Be aware of cultural nuances between French-speaking and Dutch-speaking communities in Brussels. Avoid content that might be perceived as favoring one linguistic group over another.

Content marketing plays a pivotal role in modern SEO strategies, especially for businesses in Brussels looking to enhance their online visibility and engage with their local audience. The integration of content marketing and SEO is crucial for achieving long-term success in the digital landscape. Here's how Brussels businesses can effectively combine these two powerful strategies:

  1. Develop a localized content strategy: Create content that resonates with the Brussels audience by addressing local trends, events, and concerns. This could include topics related to local business regulations, city developments, or cultural events in Brussels.
  2. Optimize for local keywords: Incorporate Brussels-specific keywords and phrases into your content. For example, 'SEO services in Brussels' or 'content marketing for Belgian businesses' can help target local searches.
  3. Create multilingual content: Given Brussels' multilingual nature, consider producing content in Dutch, French, and English to cater to a broader audience and improve your SEO reach.
  4. Leverage local link building: Collaborate with other Brussels-based businesses, organizations, and influencers to build high-quality backlinks. This can include guest posting on local blogs or partnering with Brussels-based industry associations.
  5. Utilize schema markup: Implement structured data to help search engines understand your content better, especially for local business information such as address, opening hours, and services offered in Brussels.
  6. Focus on user experience: Ensure your website is mobile-friendly and loads quickly, as these are crucial factors for both SEO and content marketing success. According to a study by SEMrush, websites that load in 1-2 seconds have the highest average position in Google search results.
  7. Create diverse content types: Develop a mix of content formats such as blog posts, infographics, videos, and podcasts to cater to different user preferences and increase engagement. This diversity can help you rank for various search queries and attract a wider audience in Brussels.
  8. Optimize for featured snippets: Structure your content to increase the chances of appearing in featured snippets, which can significantly boost visibility. According to Ahrefs, featured snippets get a 31% higher click-through rate compared to regular search results.
  9. Regularly update and refresh content: Keep your content up-to-date with the latest SEO trends and Brussels-specific information. Google favors fresh, relevant content, which can improve your search rankings.
  10. Monitor and analyze performance: Use tools like Google Analytics and Google Search Console to track the performance of your content and SEO efforts. Regularly review metrics such as organic traffic, bounce rate, and conversion rates to refine your strategy.

By integrating these content marketing and SEO strategies, Brussels businesses can create a powerful online presence that not only ranks well in search engines but also provides value to their local audience. Remember, the key is to consistently produce high-quality, relevant content that addresses the needs and interests of your Brussels-based target market while adhering to SEO best practices.
