Where international SEO actually breaks
Almost every multilingual site we look at has the same handful of defects, and none of them are content problems. They are implementation problems that a content team cannot reach, which is why they survive years of SEO retainers.
- Hreflang that does not reciprocate: page A points to B, B never points back, so Google discards the whole cluster
- Every locale canonicalising to the English URL, which tells Google the translations are duplicates and should not rank
- Translated content served on English slugs, so the URL itself carries no signal in the target language
- One locale silently falling back to English mid-page — a server component that forgot which language it was rendering
- A sitemap that lists locales the site does not actually serve, or omits the ones it does
