Introduction
Setting up hreflang is just the start. You need to monitor how search engines crawl and index your localized pages.
Key Concepts
Monitoring areas:
- Hreflang validation
- Index coverage by locale
- Search performance by country
- Crawl errors
Deep Dive
Google Search Console Setup
-
Add property for each locale subdomain/subfolder
- example.com/en/
- example.com/fr/
- example.com/de/
-
Or use URL parameter handling
- Configure locale parameters
Checking Hreflang Implementation
bash# Validate hreflang tags curl -s https://example.com/en | grep -i hreflang
Expected output:
html<link rel="alternate" hreflang="en" href="https://example.com/en" /> <link rel="alternate" hreflang="fr" href="https://example.com/fr" /> <link rel="alternate" hreflang="x-default" href="https://example.com/en" />
Common Hreflang Errors
- Missing return links (A→B but not B→A)
- Wrong language codes (en-uk vs en-GB)
- Missing self-referential hreflang
- x-default pointing to non-existent page
Performance Monitoring
typescript// Track locale in analytics const locale = params.lang; analytics.track('page_view', { locale, path: pathname, country: geo?.country, });
Summary
Monitor international SEO through Search Console, validate hreflang implementation, and track performance by locale. Fix return link errors promptly as they can hurt rankings.
