Hreflang Tag Checker
Check pasted hreflang alternate tags for language codes, absolute URLs, duplicates, and missing href values without crawling.
Hreflang Tag Checker workflow tips
Use this pasted-input SEO QA tool for copied head snippets, localization templates, or migration exports before a deeper international SEO review. It checks the pasted markup only, so use platform search tools for reciprocal and live-indexing checks after publishing.
What this tool does
Hreflang Tag Checker parses rel=alternate hreflang links from pasted HTML, lists language-to-URL pairs, counts languages, and flags common markup issues for international SEO QA.
Common use cases
Check pasted hreflang alternate tags for language codes, absolute URLs, duplicates, and missing hrefs before international SEO QA handoffs.
Use Hreflang Tag Checker during a pasted-input SEO QA pass before publishing or handing off a page. It helps review copied metadata, snippets, headings, social tags, or canonical signals without crawling a live URL.
How to use it
- Paste hreflang link tags or an HTML head snippet.
- Review the extracted hreflang language codes, alternate URLs, counts, and warnings.
- Copy the tab-separated language and URL list into QA notes or compare it with canonical checks.
Example workflow
Paste the relevant title, description, tag block, heading outline, or canonical markup from your draft page. Review the warnings and preview output, make edits in your CMS or document, then recheck the same pasted input before publishing.
