Hreflang Tag Checker V3

International SEO setups hinge on correct hreflang tags, and this extension audits them. It extracts every hreflang annotation from a page and helps verify that a multilingual or multi regional site is configured so search engines serve the right content in the right language, including the x-default fallback. The extension was originally created by Adapt Worldwide, and this version converts it to Manifest V3 because the original author had not made the upgrade. It is a page level checker filed under developer tools and fits SEO specialists who review language and region targeting.
