FAQ

What values should I enter?

Enter one language code with the full URL for that localized page on each line. You can use codes such as ko, en, ja, or x-default, and add or remove lines as needed.

Can I copy the generated tags?

Yes. You can copy the alternate link tags, x-default entry, and canonical tag expected from a hreflang generator or hreflang builder.

What should I watch out for?

Only valid URLs are included, and x-default is used as the canonical basis when present. The tool helps generate tags but does not guarantee search visibility or rankings.
