Hreflang Checker
Inspect hreflang alternate link tags on any page for international SEO.
What Is a Hreflang Checker?
Hreflang Checker fetches a webpage and extracts every <link rel="alternate" hreflang="…"> tag found in the document <head>.
These tags tell search engines which language or regional version of a page to serve to a given audience. Without them, Google and other search engines have to guess the correct version to show — which can result in the wrong language variant ranking for a query, duplicate content issues across locales, or international traffic not reaching the right page.
What the Tool Checks
| Result | What It Means |
|---|---|
| Tags found | At least one <link rel="alternate" hreflang="…"> tag was detected in the <head>. |
| No tags found | The page does not declare any hreflang link tags. This is expected for single-language sites, but may be a gap for international sites. |
| x-default present | The page includes an hreflang="x-default" fallback for users who don't match any specific language or region target. |
| x-default missing | No fallback tag was found. Consider adding one if the page has a language-selector landing page. |
How to Read the Results
The Hreflang Tags table lists every language code and its associated URL. Common codes include en (English), en-US (English — United States), fr (French), de (German), and x-default (the fallback for unmatched visitors).
Pass means one or more hreflang tags were found on the page. It confirms the tags are present in the HTML but does not validate reciprocal links, canonical alignment, sitemap coverage, or HTTP Link header alternatives.
Fail means no hreflang tags were found. If the page is part of an international site, add the appropriate <link rel="alternate" hreflang="…" href="…"> tags inside <head> for each language or region variant.
Frequently Asked Questions
Hreflang tags are HTML link elements in the page <head> that tell search engines which language or regional version of a page to serve for a given audience. For example, hreflang="en-US" targets English speakers in the United States.
The x-default hreflang value designates a fallback page for users who don't match any of the other language or region targets. It is optional but recommended when you have a language-selector landing page.
The tool fetches the page HTML, parses <link rel="alternate" hreflang="..."> tags inside <head>, and lists every language code and URL pair found. Pass means at least one tag was found; fail means none were.
