Search & AI visibility

hreflang monitoring — keep every language visible in search.

Relvato validates your hreflang cluster — reciprocal links, valid language codes, an x-default — and checks every locale variant actually loads and stays indexable, so a broken translation never costs you a whole market.

What it checks
  • The hreflang cluster is reciprocal and complete
  • Valid language/region codes and an x-default
  • Each locale variant returns 200
  • No locale accidentally set to noindex
Why it matters

hreflang is fiddly and breaks silently: a plugin update drops a return link, a routing change 404s a locale, one language slips into noindex. Google then serves the wrong language or none. Relvato re-validates the whole cluster on every change.

Works on any site — from WordPress to AI-built sites.

How it works
  • Reads the hreflang cluster and checks it’s reciprocal, uses valid language codes, and includes x-default.
  • Loads each locale variant and confirms it returns 200 and isn’t noindexed.
  • Catches a translation-plugin or routing change that breaks one language’s hreflang or deindexes it.
Questions, answered
Do I need a plugin?

No — hreflang monitoring works on any multilingual site with a verified domain.

What usually breaks it?

A translation-plugin update, or a routing/permalink change that alters one locale’s URLs.
