Technical SEO Services for Multilingual Sites

A site with five language versions multiplies its crawlable URL space by five. For large sites (10,000+ pages per language), this means Googlebot may spend most of its crawl budget on lower-priority translated pages rather than your most important pages. Managing crawl budget for multilingual sites involves optimizing crawl directives in robots.txt, ensuring strong internal linking for high-priority translated pages, and using GSC crawl stats to identify and resolve inefficiencies.

The most common mistake is a translated page canonicalizing to its English equivalent, which tells Google the translated version is a duplicate of the English page and should not be indexed separately. Other common errors include canonical tags pointing to the root domain rather than the correct locale URL, and canonical tags being inconsistent between the HTML head and the XML sitemap. All of these are identified in our multilingual technical audit.

We use Google's URL Inspection tool in Search Console to render pages as Googlebot sees them, then check whether language switcher links and hreflang tags are present in the rendered HTML. We also use Screaming Frog with JavaScript rendering enabled to crawl the site as a browser would. If critical multilingual elements only appear in the DOM after JavaScript execution and Google cannot render them, we document the issue and provide fix recommendations for your development team.
