A feature of the Hreflang Manager plugin for WordPress
Hreflang Manager implements hreflang following Google’s hreflang specifications and fully supports all relevant ISO standards for languages, scripts, and regions. This implementation allows you to configure simple or complex international and multilingual setups while ensuring maximum compatibility and complete flexibility.
Hreflang is not just a configuration detail, it is a technical specification governed by Google’s guidelines and multiple ISO standards. Even small deviations, such as invalid codes or unsupported combinations, can cause hreflang annotations to be ignored entirely.
Hreflang Manager is built with strict compliance in mind. Every hreflang tag generated by the plugin follows the official standards, giving you confidence that your implementation is technically correct, future-proof, and recognized by search engines.
Hreflang Manager outputs hreflang annotations as <link rel="alternate" hreflang="…"> tags in the <head> section of each page. This is the most widely supported and recommended method for hreflang implementation and works with any theme or front-end setup.
The implementation is independent of page builders, content editors, or front-end frameworks, making it suitable for both simple websites and complex enterprise networks.
Hreflang Manager supports all languages defined by the ISO 639-1 standard, allowing you to target every officially recognized two-letter language code.
This makes the plugin suitable not only for common languages, but also for less frequently used or highly specialized language setups.
Hreflang Manager fully supports ISO 15924 script codes, enabling precise targeting for languages that use multiple writing systems.
For example, you can correctly differentiate between Simplified and Traditional Chinese or other script-specific variations, ensuring search engines understand exactly which version should be shown to each audience.
The plugin supports all ISO 3166-1 alpha-2 country codes, allowing you to create region-specific hreflang combinations for any country worldwide.
This makes Hreflang Manager suitable for global businesses, international publishers, and regionally targeted content strategies.
Hreflang Manager allows you to define an x-default hreflang value to specify a fallback page when no language or regional match applies.
This is especially useful for:
The x-default option is implemented according to Google’s specifications and integrates seamlessly with other hreflang annotations.
The Pro version of Hreflang Manager supports up to 100 alternate pages per URL.
This makes it suitable for large multilingual networks and enterprise-level installations where a single page may have dozens of localized or regional variants.
