Do I need a self-referencing hreflang tag on each page?

Yes, each language/region version should include a tag pointing to itself as well as to every other version — that's part of what makes hreflang implementation easy to get wrong by hand.

What format do the language and region codes use?

Standard ISO language codes (like "en") optionally combined with region codes (like "en-GB"), following the format search engines expect.

What happens if hreflang tags are implemented incorrectly?

Search engines may show the wrong regional version to users, or ignore the hreflang signals entirely, undermining the international targeting you were trying to set up.

Does Hreflang Tag Generator upload my files to a server?

No. Hreflang Tag Generator runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Sites with versions in multiple languages or targeting different regions need hreflang tags to tell search engines which version to show to which audience, but the tag syntax (language and region codes, bidirectional linking between every version) is intricate and easy to get wrong at scale. This tool generates correctly formatted hreflang link tags for your multi-language or multi-region pages, reducing the risk of a malformed tag that could misdirect search engines to the wrong regional version.
