URL Structure for International SEO
Choosing the right URL structure is crucial for international SEO success, affecting how search engines understand your geographic and linguistic targeting.
URL Structure Options Comparison
URL Structure Decision Matrix:
Structure | Example | Pros | Cons |
---|---|---|---|
ccTLD | example.uk example.fr | Strong geo-targeting User trust | Expensive Link authority split |
Subdomain | uk.example.com fr.example.com | Easy setup Flexible targeting | Weaker geo-signal Authority dilution |
Subdirectory | example.com/uk/ example.com/fr/ | Shared authority Cost effective | Weaker geo-targeting Complex management |
Parameter | example.com?cc=uk example.com?cc=fr | Easy implementation Flexible | Poor SEO signals Not recommended |
Recommended URL Structure Implementation:
For Most Businesses (Subdirectory):
• English (Global): example.com/
• Spanish (Spain): example.com/es/
• French (France): example.com/fr/
• German (Germany): example.com/de/
• English (UK): example.com/uk/
For Large Enterprises (ccTLD):
• Global: example.com
• Spain: example.es
• France: example.fr
• Germany: example.de
• UK: example.co.uk
Technical Implementation Best Practices
URL Structure Configuration:
# .htaccess for subdirectory structure RewriteEngine On # Redirect based on Accept-Language header RewriteCond %{HTTP:Accept-Language} ^es [NC] RewriteRule ^$ /es/ [R=302,L] RewriteCond %{HTTP:Accept-Language} ^fr [NC] RewriteRule ^$ /fr/ [R=302,L] RewriteCond %{HTTP:Accept-Language} ^de [NC] RewriteRule ^$ /de/ [R=302,L] # Default to English RewriteRule ^$ /en/ [R=302,L] # Subdirectory handling RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([a-z]{2})/(.*)$ /$2?lang=$1 [QSA,L]
Server Configuration for ccTLD:
# DNS Configuration example.com A 192.168.1.100 example.es A 192.168.1.101 example.fr A 192.168.1.102 example.de A 192.168.1.103 # Server blocks for different ccTLDs server { listen 80; server_name example.es; root /var/www/html/es; index index.html index.php; location / { try_files $uri $uri/ =404; } }
Hreflang Implementation Mastery
Hreflang tags are essential for international SEO, helping search engines understand which language and region each page targets, preventing duplicate content issues across international versions.
Hreflang Tag Implementation
HTML Head Implementation:
<!-- Hreflang tags in HTML head --> <link rel="alternate" hreflang="en" href="https://example.com/page" /> <link rel="alternate" hreflang="es" href="https://example.com/es/page" /> <link rel="alternate" hreflang="fr" href="https://example.com/fr/page" /> <link rel="alternate" hreflang="de" href="https://example.com/de/page" /> <link rel="alternate" hreflang="en-gb" href="https://example.com/uk/page" /> <link rel="alternate" hreflang="en-us" href="https://example.com/us/page" /> <link rel="alternate" hreflang="x-default" href="https://example.com/page" /> <!-- Self-referencing hreflang (required) --> <link rel="alternate" hreflang="en" href="https://example.com/page" /> <!-- Regional targeting examples --> <link rel="alternate" hreflang="es-mx" href="https://example.com/mx/page" /> <link rel="alternate" hreflang="es-ar" href="https://example.com/ar/page" /> <link rel="alternate" hreflang="pt-br" href="https://example.com/br/page" />
XML Sitemap Hreflang Implementation:
<?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/1999/xhtml"> <url> <loc>https://example.com/page</loc> <xhtml:link rel="alternate" hreflang="en" href="https://example.com/page"/> <xhtml:link rel="alternate" hreflang="es" href="https://example.com/es/page"/> <xhtml:link rel="alternate" hreflang="fr" href="https://example.com/fr/page"/> <xhtml:link rel="alternate" hreflang="de" href="https://example.com/de/page"/> <xhtml:link rel="alternate" hreflang="x-default" href="https://example.com/page"/> </url> <url> <loc>https://example.com/es/page</loc> <xhtml:link rel="alternate" hreflang="en" href="https://example.com/page"/> <xhtml:link rel="alternate" hreflang="es" href="https://example.com/es/page"/> <xhtml:link rel="alternate" hreflang="fr" href="https://example.com/fr/page"/> <xhtml:link rel="alternate" hreflang="de" href="https://example.com/de/page"/> <xhtml:link rel="alternate" hreflang="x-default" href="https://example.com/page"/> </url> </urlset>
