<!-- Hreflang Tags for Multi-Regional SEO --> <link rel="alternate" hreflang="x-default" href="https://example.com/software" /> <link rel="alternate" hreflang="en-us" href="https://example.com/software/en-us" /> <link rel="alternate" hreflang="en-gb" href="https://example.com/software/en-gb" /> <link rel="alternate" hreflang="es-es" href="https://example.com/software/es" /> <link rel="alternate" hreflang="de-de" href="https://example.com/software/de" /> <link rel="alternate" hreflang="fr-fr" href="https://example.com/software/fr" />
x-default.What this tool does and who it is for
Hreflang tags tell search engines which language or regional version of a page to show to which audience. Enter your base URL, edit the list of locale codes and paths, and the tool prints one link rel alternate tag per row, ready for the head section.
The starter list includes x-default, en-us, en-gb, es-es, de-de and fr-fr, and you can add or remove rows. Each tag URL is your base URL plus the path you type for that row.
Hreflang is for pages that exist in several versions. If your site is a US English site, you do not need it, and a US-only site with one version gains nothing from the tags.
Official Formula / Technical Standard
Real-World Worked Scenario
An e-commerce store maps https://example.com/en-us and https://example.com/en-gb with an x-default fallback.
When people use it
US and UK English versions
A shop with different spellings and currencies for en-US and en-GB pages can mark the pairs so each audience sees the right one.
Adding Spanish for US readers
A US business serving Spanish speakers can use es-US for a Spanish page aimed at the United States, rather than es-ES.
Site migration check
Generate the tags for a new locale folder structure and compare to the live head output.
Notes for US users
- Use en-US for American English. The tool's starter code is lowercase en-us, which search engines generally treat the same, but you can type en-US to match Google's examples.
- Spanish for a US audience is es-US, and the starter list has es-es for Spain. Change codes to match who you actually serve.
- Google uses hreflang as a hint, not a command. It may still show a different version if signals conflict.
- A language-only code such as es is valid, but a country must be paired with a language. A bare country code is wrong.
Limits and what to double-check
- •The tool prints tags for one page set. You must put the full set of tags on every page in the group, including a self-reference, and the confirm-back rule means each version must link to the others.
- •Codes are free text with no validation, so a typo produces a bad tag. Check each code against the ISO 639-1 language and ISO 3166-1 country lists.
- •It outputs HTML link tags only. It does not make HTTP header or sitemap versions.
Expert Best Practices & Common Pitfalls

Frequently Asked Questions
What does x-default mean?▼
x-default tells Google which page to show visitors when no language or region matches their browser settings.
Do I need hreflang for a US-only site?▼
No. Hreflang matters when you have the same or similar content in several languages or regions. A single English site aimed at the US has no alternates to point to, and adding tags would add maintenance for no benefit. Add it later if you launch a genuinely separate regional or language version of your pages.
Should hreflang be in the head or the sitemap?▼
Either works, as long as you use one consistently. Head tags are simple for small sites. For big sites, sitemap annotations are easier to maintain. This tool writes head tags. Do not mix methods in conflicting ways. Whichever method you pick, make sure every version of a page lists itself and all of its alternates.
Why isn't Google showing my regional version?▼
Common causes are missing return links, wrong codes, canonical tags pointing to another version, or redirects. Hreflang is a hint, so strong signals elsewhere can override it. Check that each page lists itself and every alternate, using absolute URLs. Google's international targeting documentation walks through these checks if you want the official wording.
Do I need to translate everything to use hreflang?▼
Hreflang applies to pages that are the same or very similar in different languages or regions, such as US and UK English. It is not meant for unrelated pages. Machine translation without review may reflect badly on quality, so check the language.
