Critical technical elements include:

1. Domain strategy (ccTLDs, subdomains, or subfolders)
2. Proper hreflang implementation with bidirectional references
3. Country-specific hosting or CDN implementation for performance
4. Geotargeting settings in Google Search Console
5. Mobile responsiveness across international variants
6. Structured data adaptation for each market

Getting these technical foundations right prevents most common international SEO failures.
