A worked example
en and zh-CN URLs generate two alternate links; add x-default for an explicitly chosen fallback.
Language tags
Create reciprocal hreflang tag blocks for supplied language and page-URL pairs.
YOUR LITTLE WORKBENCH
ON YOUR DEVICE ✦Language tags
Work from supplied text and URLs. Example.com is a sample; replace it with your own real addresses. Nothing is fetched, uploaded or submitted.
Install this complete set on every supplied page
<link rel="alternate" hreflang="en" href="https://example.com/" /> <link rel="alternate" hreflang="zh-CN" href="https://example.com/zh/" /> <link rel="alternate" hreflang="x-default" href="https://example.com/" />
Use ISO 639-1 languages, optionally with an ISO 3166-1 country. This tool does not support script tags or verify remote return links.
These tools do not submit to Google or predict rankings. robots.txt controls crawling, not access security; the preview does not reproduce every search display or snippet rewrite.
THE METHOD / 01
A clear wayfrom start to finish.
Each language code must be unique; every supplied page should include the same full set, including self-reference. x-default is optional.
Keep the assumptions clear
Checks basic supported language/region codes, not remote reciprocal links. Install the tags on the actual pages and verify deployment separately.
A FEW USEFUL ANSWERS
Good to know.
Are my inputs uploaded?
No. Processing runs locally in your browser. The host still receives normal requests for website pages and assets.
Can I keep my result?
Use the download controls for the current tool or print from your browser. Seating plans, flashcards and document drafts autosave in this browser; see the privacy page.
Do I need an account?
No sign-up, paid API or subscription is required. Both languages use the same tools. English always opens at the root address.
