How do I generate hreflang tags for my multilingual site?

List each language version on its own line as "code, URL" — for example "es, https://example.com/es/" — add an x-default URL if you have a fallback page, and run the tool. It outputs a ready-to-paste block of tags plus a canonical tag, with duplicates and bad URLs caught before you publish.

What are multilingual SEO tags and where do I put them?

Hreflang tags tell Google which language or regional version of a page to show each visitor, so your Spanish readers land on the Spanish page instead of the English one. Paste the generated block into the of every language version of the page — and mirror the same block on each version so the annotations are reciprocal.

Can this tool generate a canonical URL tag too?

Yes — alongside the hreflang block you get a canonical tag built from your first listed URL, which is normally your primary language page. If your canonical page differs (for example a different primary URL per version), edit the href before pasting.

How do I check my hreflang tags for duplicate language codes?

Paste your list into this tool — it detects duplicates case-insensitively (so "en" and "EN" count as the same code) and reports the exact line numbers, refusing to generate tags until you fix them. Conflicting hreflang annotations make Google ignore the whole set, so this check matters.

What is the x-default hreflang tag for international SEO?

The x-default tag points to the page visitors should see when none of your language versions match their language or region — usually your homepage or a language-selector page. It is optional, but Google recommends it, and this tool adds the line automatically when you fill in the x-default URL field.

Do hreflang tags need absolute URLs?

Yes — Google ignores relative URLs in hreflang annotations. This tool requires full https:// URLs on every line and rejects anything else, naming the exact line so you can fix it fast.

Tags are built with the algorithm of the vendored canonical-hreflang engine (0xelitesystem/canonical-hreflang-tag-helper, MIT): attribute values are HTML-escaped (&, <, >, ") and each version becomes <link rel="alternate" hreflang="..." href="..."> in your input order, plus an x-default line when you provide one. Duplicate language codes are detected case-insensitively exactly as the engine flags them — this tool goes further and blocks duplicates, because Google ignores conflicting hreflang. Limitations: the tool cannot verify that your tags are reciprocal across pages or that the URLs return 200 — it validates format only.
