hreflangfrfr

hreflangfrfr refers to using the hreflang attribute with the language-region code fr-FR to indicate a page is in French as used in France. The language code fr follows ISO 639-1, and the region code FR follows ISO 3166-1 alpha-2. While the term itself is not a separate standard, fr-FR is the conventional way to denote French for France in hreflang annotations.

Hreflang is an HTML attribute used in link elements within the head of a web page to signal language and optionally the region for alternate pages. It can also be declared in HTTP headers or in XML sitemaps. The purpose is to help search engines serve the most appropriate version of a page to users based on language and location, reducing duplicate content issues and improving user experience.

Implementation typically involves listing all language/region variants on every localized page, with self-referencing links and links to other variants. Example:

<link rel="alternate" href="https://example.com/fr-fr/" hreflang="fr-FR" />

<link rel="alternate" href="https://example.com/en-us/" hreflang="en-US" />

<link rel="alternate" href="https://example.com/" hreflang="x-default" />

Using a consistent set of hreflang values across pages and validating them with tools helps ensure correct indexing.

Common considerations include using the correct codes (fr-FR for French in France, fr-CA for French in Canada, etc.), ensuring all variants are interlinked, and including an x-default tag for pages that should serve as a fallback. While hreflang improves the likelihood of serving the right page, it does not guarantee ranking changes.
