International SEO is mostly a technical signaling problem: telling search engines which version of a page belongs in front of which audience.
The core tool: hreflang
Hreflang tags tell search engines which language and regional version of a page to serve. Getting this wrong is one of the most common international SEO mistakes — mismatched or missing return tags silently break the whole setup.

- Avoid auto-redirecting based on IP alone — let users switch manually too
