The problem
You translated the site. Google still shows the wrong one.
Without hreflang, a search engine guesses which language page to show, and it usually guesses the one it crawled first. The fix is simple to describe and painful to write by hand.
The English page ranks in Hindi search
Someone searching in Hindi lands on your English page, sees nothing they can read and leaves. Your Hindi page exists; nobody told Google it is the same page in another language.
Each set names every language version, so the right one is shown.
“No return tags” — and the set is ignored
Hreflang only counts when every page in a set points back to every other page, including itself. One missing pair and the whole set is dropped. It is the most common hreflang error there is.
Every URL carries the full set. Return tags cannot be missing.
40 pages × 5 languages = 200 tags to type
A CMS plugin bolts it on. A static site has nothing. Writing it by hand means one link per language on every page, each URL exact, each code valid, and doing it again whenever a page is added.

How it works
URLs to hreflang sitemap in three steps
STEP 01
Add your URLs
Paste every URL in every language, one per line. Or drop the ZIP of your site, or paste your existing sitemap.xml. The language is read from each URL.
/about → en
/hi/about → hi
fr.example.com/about → fr
example.de/ueber-uns → de (map)
/hi/about → hi
fr.example.com/about → fr
example.de/ueber-uns → de (map)
STEP 02
Check the sets
Translations of one page are grouped. The Table view lays every page against every language, so a missing translation or a bad code shows up before it becomes a Search Console error.
| Page | en | hi | fr |
|---|---|---|---|
| / | ✓ | ✓ | ✓ |
| /about | ✓ | ✓ | — |
| /services/mri-scan | ✓ | ✓ | ✓ |
STEP 03
Download and submit
Save sitemap.xml to your site root, add it to robots.txt, submit it in Search Console. Every URL now links to every language and to itself.
<url>
<loc>https://example.com/about</loc>
<xhtml:link hreflang="en" .../>
<xhtml:link hreflang="hi" .../>
<xhtml:link hreflang="x-default" .../>
</url>
<loc>https://example.com/about</loc>
<xhtml:link hreflang="en" .../>
<xhtml:link hreflang="hi" .../>
<xhtml:link hreflang="x-default" .../>
</url>
What a good one looks like
Six rules. Break one and the set is ignored.
Google is strict about hreflang because a half-right set is worse than none. Every file this tool writes follows all six.
Rules the file follows
- Self-referencing — each URL’s set includes the URL itself. Without it the set does not validate.
- Reciprocal — if A lists B, B lists A. Every URL in a set gets the identical alternate list, so return tags are never missing.
- Absolute URLs —
https://example.com/hi/about, never/hi/about. Relative paths in a sitemap are dropped. - Valid codes — ISO 639-1 language (
hi,en), optional ISO 3166-1 region (en-IN,pt-BR), optional script (zh-Hant). Codes are checked;en-UKandengare flagged. - One x-default per set — the page to show when no language matches. Usually the default language; never two.
- Within limits — 50,000 URLs and 50 MB uncompressed per file. Past that, split by language and list the files in a sitemap index.

How we compare
Most generators want a form per page. This one reads your URLs.
An hreflang file is only right if every set is complete. That takes grouping and checking, not a text box per language.

FAQ
Got questions?
A normal XML sitemap where each
<url> also lists every language version of that page as <xhtml:link rel="alternate" hreflang="...">. It tells search engines which URL to show to which language or country, without adding tags to every page. Need a plain one first? Use the XML Sitemap Generator.All three are valid and equal to Google. A sitemap keeps every set in one file, which is easiest to maintain on a static site and adds no bytes to your pages. Link tags in
<head> work when you cannot edit the sitemap; the Link tags view writes them from the same sets. HTTP headers are for non-HTML files like PDFs. Pick one method; do not mix them with different sets.The URL to show when none of the listed languages matches the visitor: usually the default-language page or a language selector. It is optional but recommended, and each set should have exactly one. The x-default option picks the default-language URL in each set; switch it off if you handle this elsewhere.
A two-letter ISO 639-1 language code (
en, hi, ta, fr), optionally followed by an ISO 3166-1 alpha-2 region (en-IN, pt-BR) and optionally an ISO 15924 script (zh-Hant). Region alone is not valid, and neither is en-UK (it is en-GB) or eng. Invalid codes are flagged in the Table view. To turn a detected en into en-IN, add en=en-IN to the Map box.That is what region codes are for. If
example.com/in/ and example.com/uk/ are both English, map them: in=en-IN, uk=en-GB in the Map box, and set Detect from to path prefix. Set x-default so one of them is the fallback for everyone else.Hreflang only counts when every page in a set points back to every other page in the set, including itself. If the English page lists the Hindi page but the Hindi page does not list the English one, Google ignores both. This tool writes the complete set on every URL, so the error cannot come from the sitemap. If it persists, check that no page has a canonical pointing somewhere else.
No. Hreflang is for pages that exist in more than one language or for more than one country. A single-language site needs a plain sitemap; single-language pages on a multilingual site are kept in the file as ordinary entries when Keep single-language pages is on, without alternates.
