Multilingual URL & hreflang Planner
Multilingual SEO breaks silently: one missing reciprocal tag and Google discards the whole annotation. Pick your languages and markets and this planner gives you a recommended URL structure and a copy-ready, reciprocal hreflang + canonical head block.

How it works
For a Swiss site with German, French, Italian and English, the two decisions that matter are the URL structure (prefix vs subdomain vs subdirectory) and a correct, reciprocal hreflang set with self-referencing canonicals. This planner generates both, previews the exact head block to paste, and flags the pitfalls that quietly break multilingual rankings — slug drift, non-reciprocal tags, canonicals pointing at the wrong locale.
It is grounded in Google’s documentation on localized versions and the BCP 47 language-tag standard, and mirrors the real i18n architecture this very site runs on. Nothing you enter is stored.
- Choose your languages and markets.
- Read the recommended URL structure.
- Copy the generated hreflang + canonical head block and review the pitfalls.
Frequently asked questions
- What is the most common hreflang mistake?
- Non-reciprocal tags: every locale must list all the others and itself, or Google ignores the whole set. The planner builds a reciprocal set for you.
- Prefix, subdomain or subdirectory?
- It depends on your setup; the planner recommends one based on your inputs and explains the trade-off.
