Hreflang annotations tell search engines that several URLs are equivalent versions intended for different languages or regions. This generator converts each language-and-URL pair into a link element that can be placed in the head of every page in the group. It also supports x-default for a neutral selector or fallback page.
The tags are only useful when the URLs are live, indexable, canonical, and genuinely equivalent. Every listed page should return the same set of alternate annotations, including a reference to itself. The generator formats the tags but does not crawl the URLs, verify reciprocal links, confirm canonical tags, or decide whether translated pages have equivalent intent.
