Frequently Asked Questions

Why hreflang matters?
Tells Google which version of your page to show users in different countries / languages. Without: you may rank in wrong country, or one version cannibalizes another. Used by Google + Yandex + Yahoo. Bing has limited support.
x-default — what is it?
The fallback URL when no language match — typically your default version. Example: site has en, de, fr, but a Japanese user lands → x-default URL is shown. Best practice: always include x-default pointing to your most-popular or English version.
Common mistakes?
(1) Forgot bidirectional: A→B requires B→A — Google ignores one-way hreflang. (2) Wrong locale code: it's `en-US` not `en_US`, `de-DE` not `de_DE`. (3) Pointing to redirected URL: must be canonical 200-status URL. (4) Missing x-default. (5) Using hreflang on non-self-canonical pages.
