Explanation

To make sure search engines understand which language versions of your site are available, you can add hreflang tags to your WordPress site's header. This helps direct users to the right language version of your site.

Here's a simple way to do it:

First, you define a list of language versions with their respective URLs. For example, English, Spanish, and French.
Then, you check the current language of the page using get_locale().
For each language in your list, you add a <link rel="alternate" hreflang="..."> tag, but only if it's not the current language. This prevents duplication.

Finally, you hook this function to the wp_head action, which ensures these tags are added to the header of your site.

This setup helps search engines and users find the correct language version of your site, improving user experience and SEO.

Code

<?php
// Function to add hreflang tags to the header
function wp_dudecom_add_hreflang_tags() {
    // Define the hreflang tags for different language versions
    $hreflang_tags = array(
        'en' => 'https://example.com/en/',
        'es' => 'https://example.com/es/',
        'fr' => 'https://example.com/fr/',
        // Add more languages as needed
    );

    // Get the current language code
    $current_language = get_locale();

    // Output hreflang tags
    foreach ($hreflang_tags as $lang_code => $url) {
        // Ensure the current language is not duplicated
        if ($current_language !== $lang_code) {
            echo '<link rel="alternate" hreflang="' . esc_attr($lang_code) . '" href="' . esc_url($url) . '" />' . "\n";
        }
    }
}

// Hook the function to wp_head action
add_action('wp_head', 'wp_dudecom_add_hreflang_tags');
?>
