A multilingual site introduces a unique set of technical SEO challenges that a standard technical audit does not catch. Crawl budget becomes critical when a site has five language versions of every page. Canonical tags that work fine for a monolingual site create duplicate content problems when they reference the wrong language version. JavaScript-rendered language switchers prevent Google from discovering translated content entirely. Pagination for multilingual archives creates indexed pages with near-duplicate content across locales.
Our technical SEO audit for multilingual sites is designed around these specific failure modes. Using Screaming Frog with full JavaScript rendering enabled and cross-referenced against Ahrefs site data, we identify every technical issue affecting your multilingual setup and deliver a prioritized fix list with implementation instructions for each item. We also run per-language-version page speed analysis through PageSpeed Insights and Lighthouse to ensure performance is consistent across all locales.
