hreflang Generator

Your site has a Portuguese and an English version, and Google keeps serving the wrong one: Brazilians landing on the English page, Americans on the Portuguese one. hreflang tags exist for exactly this, but writing them by hand is tedious and typo-prone. Here you list one pair per line, in the format pt-BR space URL, and get the block of link rel=alternate tags ready to copy into your head section.

The classic hreflang trap is reciprocity: every version of the page must list all the others and itself. If page A points to B but B does not point back, Google ignores the whole pair. Another one: the code must be a language (ISO 639-1) plus an optional region (ISO 3166-1). Using just br is a common and costly mistake: br means Breton, not Brazil; the right code is pt-BR. The tool accepts whatever you type and silently skips malformed lines, so check that the output has as many tags as your input has lines.

Paste the same block into the head of every version of the page, trimming nothing. Add an x-default line pointing to your fallback version, the one to show visitors who match none of the listed languages. Make sure every URL returns a 200: hreflang pointing at a redirect or a 404 gets dropped. On sites with thousands of pages, consider declaring hreflang in the sitemap instead of the head.
