Hreflang
为何重要
Hreflang tags tell search engines which language or regional version of a page to show each user. Errors can show the wrong language or ignore the tags entirely.
如何修复
- Link every language version to all others, including itself.
- Use valid codes such as en, en-GB or de-AT.
- Add an x-default for the fallback page and keep return links consistent.
使用以下工具检查
- Hreflang Checker – Validate hreflang tags and confirm each language version links back.
- Hreflang Tag Generator – Generate hreflang link tags for every language and region version of a page.
