Hreflang Checker
Validate a page's hreflang implementation: are the language-region codes real, does the page reference itself, is there an x-default, and, the one everyone gets wrong, do the alternate pages link back? Search engines ignore hreflang pairs without return tags.
Hreflang breaks sitewide, quietly.
One template change can silently break return tags on every translated page. The full audit validates hreflang coverage, targets, and codes across the whole crawl, alongside everything else.
