Hreflang Tag Generator
{"slug":"generatore-hreflang","en_slug":"hreflang-generator","h1":"Hreflang Tag Generator","card":"Generate correct hreflang tags for every language and country version of your pages, ready to paste into your site.","title":"Hreflang Tag Generator — Free International SEO Tool","desc":"Free hreflang tag generator: create valid hreflang and x-default tags for multi-language sites in seconds. No signup, instant results.","kw":"hreflang generator, hreflang tag, international SEO, multi-language SEO, x-default tag, hreflang checker","intro":["If your business has a website in more than one language or targets more than one country, search engines need a clear signal about which page to show to which visitor. That signal is the hreflang tag: a small piece of code in your page's that tells Google \"this page is the English version, that one is the Italian version, this one is for UK visitors.\" Get it wrong — a common mistake even on well-built sites — and you risk the wrong language ranking in the wrong country, or worse, your pages competing against each other in search results.","This tool builds the correct hreflang markup for you: enter your page URLs and their language/country codes, and it generates the full set of tags, including the x-default fallback, ready to paste into your site's code. It will not fix a site's underlying structure or content strategy — for that, our SEO & GEO visibility service looks at the whole picture, from technical setup to content targeting per market. If you are building or rebuilding a multi-language site altogether, our websites for SMEs service can set this up correctly from day one."],"how":["List each language/country version of the same page, with its full URL.","Assign the correct language code (and country code, if relevant) to each URL.","Copy the generated hreflang tags and paste them into the of each corresponding page."],"faq":[{"q":"What is a hreflang tag and do I really need one?","a":"It is an HTML attribute that tells search engines which language and, optionally, which country a page is aimed at. You need it whenever the same content exists in more than one language or targets more than one country, so the right version is shown to the right audience."},{"q":"What is the x-default tag for?","a":"It marks the page to show visitors whose language or country does not match any of your other versions, such as a language selector page or your main international page. It is optional but recommended if you have more than one market."},{"q":"Do hreflang tags have to be reciprocal across all pages?","a":"Yes: every page in the group must reference every other version, including itself. If tags are missing or inconsistent between pages, search engines may ignore the whole set, so double-check the generated code across all your language versions before publishing."}]}
