이 도구에 대해
Check multilingual hreflang sets before release so alternate URLs stay consistent across languages and regions.
Hreflang Checker validates the alternate language and region annotations that tell search engines which version of a page to serve to users in different locales. It verifies correct ISO language and region codes, checks for reciprocal return tags, and flags missing x-default entries that leave international targeting incomplete.
- Validates locale codes like en, en-US, ko-KR, and x-default.
- Flags duplicate codes, duplicate URLs, and invalid absolute URLs.
- Generates cleaned alternate link tags from valid entries.
사용 방법 Hreflang Checker
Paste the hreflang tags from your page head, or provide a URL for the tool to inspect. It cross-checks every language-region pair, confirms that all alternate pages link back to each other, and highlights any orphaned or non-reciprocal annotations that could confuse search engine locale selection.
When this tool is useful
- Review alternate language and region mappings before launching localized pages.
- QA hreflang exports from a CMS or spreadsheet before engineering deploys them.
- Catch duplicate locale rows or missing x-default entries during international SEO audits.
Practical tips
- Keep alternate URLs absolute and consistent in protocol and host when possible.
- Use x-default for the fallback experience when you have a global selector or catch-all page.
- Validate the final live HTML too, because generated tags can still be altered by templates.
이 도구를 찾는 이유
Incorrect hreflang implementation causes search engines to show the wrong language version to users, which degrades user experience and wastes crawl budget on pages that will not convert. Because hreflang errors compound across thousands of localized pages, validating the setup before deployment prevents costly rework.
