Limit the size of the existing and new permalink slugs in Wordpress for SEO

0 votes

 read an article on Google that says for good SEO it is best that the size of the slug in the URL is limited to 5 words.

As I use WordPress the link is assigned automatically to the article title. To redo all the links with just 5 words I would have to spend months editing all the links on my blog.

Would it be possible to do this automatically? There is some function or code for that. I found this code and added it to the function page of my theme and had no results.

See the code:

function pm_limit_slugs_length($uri) {
    $max_words = 5; // If any part of URI contains more than 5 words, the slug will be limited to first 5 words
    $new_title = '';
    $slugs = explode('/', $uri);
    
    for($i=0, $count = count($slugs); $i < $count; $i++) {
        $slug = $slugs[$i];
        $words = explode('-', $slug);
        
        $new_title .= "/";
        if(count($words) > $max_words) {
            $new_title .= implode("-", array_slice($words, 0, $max_words));
        } else {
            $new_title .= $slug;
        }
    }
    
    // Remove trailing slashes
    $new_title = trim($new_title, "/");
    
    return $new_title;
}
add_filter('permalink_manager_filter_default_post_uri', 'pm_limit_slugs_length', 99);
add_filter('permalink_manager_filter_default_term_uri', 'pm_limit_slugs_length', 99);

I found the code here: https://permalinkmanager.pro/docs/filters-hooks/how-to-limit-the-number-of-words-in-wordpress-permalinks/

How can I use it to limit the Wordpress slug size to 5 words?

?php  
/**
 * Trim native slugs
 */
function pm_trim_native_slug($slug, $post_ID, $post_status, $post_type, $post_parent) {
    global $wpdb;

    $max_words = 5; // Limit the number of words to 5; This value can be changed.
    $words = explode('-', $slug);

    /* UPDATED CODE TO REMOVE SHORT WORDS */
    $min_word_length = 2;

    foreach ($words as $k => $word) {
        if (strlen($word) <= $min_word_length)
            unset($words[$k]);
    }
    /* END OF UPDATED CODE FOR SHORT WORDS */

    if(count($words) > $max_words) {
        $slug = implode("-", array_slice($words, 0, $max_words));

        // Make the slugs unique
        $check_sql       = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND ID != %d LIMIT 1";
        $post_name_check = $wpdb->get_var($wpdb->prepare($check_sql, $slug, $post_ID));

        if($post_name_check) {
            $suffix = 2;
            do {
                $alt_post_name = _truncate_post_slug($slug, 200 - (strlen($suffix) + 1)) . "-$suffix";
                $post_name_check = $wpdb->get_var($wpdb->prepare($check_sql, $alt_post_name, $post_type, $post_ID, $post_parent));
                $suffix++;
            } while ($post_name_check);
            $slug = $alt_post_name;
        }
    }

    return $slug;
}
add_filter('wp_unique_post_slug', 'pm_trim_native_slug', 99, 5);

this code is to automatically remove short words from url
after this update the eisting slugs

<?php
    include('wp-load.php');           //Include the wp-load.php file
    define('WP_USE_THEMES', false);   //We don't need the theme files

    echo "<p>About to update all slugs...</p>";
    limit_all_existing_slugs();
    echo "<p>...DONE</p>";
?>

call this function to update the slugs
