What is hreflang?
hreflang is an HTML attribute that tells Google the language and geographic region of a page. Essential for multilingual sites.
Implementation methods
You can use three methods: in the page head with link rel="alternate", in the XML sitemap, or in HTTP headers.
Common structures
Country domains (.es, .mx, .com)
Offers the best segmentation but requires more maintenance.
Subdirectories (/es/, /en/)
Easy to manage and maintains the main domain authority.
Subdomains (es.site.com)
Useful for very different languages but fragments authority.
Common mistakes
Not including the current page in the hreflang set, using incorrect language codes, or having inconsistent hreflang across pages.
Content strategy
Create unique content for each language. Literal translation doesn't work well for SEO. Adapt the message to each culture.
