When managing a WordPress site, one of the most important SEO practices is ensuring that your URLs (slugs) are user-friendly and relevant to your content. Often, when you update a post title, the URL or slug doesn’t automatically adjust, which can lead to outdated or inconsistent links. To maintain an optimal structure and improve your site’s SEO, it’s crucial that your slugs reflect changes made to post titles. This blog will guide you on how to implement a function that automatically updates the slug whenever you change a post title in WordPress, keeping your URLs fresh and SEO-friendly.
Understanding WordPress Slugs and Their Importance
The URL slug is the part of the URL that identifies a specific page or post on your WordPress site. It is essential for both search engines and users to easily understand the content of the page from the URL. A clean, descriptive slug helps with SEO, as search engines favor keywords in URLs that are relevant to the content. Without proper slug management, your website may suffer from poor search rankings or broken links. Therefore, ensuring that slugs reflect post titles can make a significant difference in your website’s visibility and usability.
The Problem with Manual Slug Updates
When you update the title of a WordPress post, the URL slug doesn’t automatically update. This leads to a mismatch between the post’s title and the URL, which can confuse both search engines and users. Manually updating the slug every time you change a post title can be tedious and error-prone. Moreover, it increases the risk of broken links if you forget to update the slug or if old links are still indexed by search engines. An automatic function to sync the slug with the post title can save time and maintain URL consistency.
How WordPress Handles Slugs by Default
By default, WordPress generates a post’s URL slug based on the title you set for it. The title is converted into a slug by replacing spaces with hyphens and removing special characters. However, this automatic slug creation only happens when the post is first published, not when the title is updated later. This limitation is what can cause discrepancies between the post title and the slug, which is why automating the process is crucial for maintaining a clean and SEO-friendly site structure.
How to Implement the Function for Slug Updates
To automatically update the slug when you change the title of a post in WordPress, you can use a simple function added to your theme’s functions.php
file. This function will hook into the post save action and ensure the slug is updated each time the post title changes. The following is a sample function to achieve this:
function update_post_slug_on_title_change($post_id) {
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return $post_id;
$post = get_post($post_id);
if ($post->post_type == 'post') {
$new_slug = sanitize_title_with_dashes($post->post_title);
// Update the post's slug
wp_update_post(array(
'ID' => $post_id,
'post_name' => $new_slug
));
}
return $post_id;
}
add_action('save_post', 'update_post_slug_on_title_change');
This code listens for changes to the post title and updates the slug accordingly. It ensures that the slug stays in sync with the title, keeping your URLs clean and SEO-friendly.
Testing the Function After Implementation
Once you’ve added the function to your functions.php
file, it’s time to test it. Create a new post and add a title, then save or publish it. Afterward, go back and change the post title and save the post again. The slug should automatically update to reflect the new title, making sure the URL remains consistent with the content. If the slug does not update, check your code for errors or conflicts with other functions.
Why Automatic Slug Updates Improve SEO
Having consistent slugs is critical for SEO because search engines use URLs to understand the content of a page. If your post title changes but the slug remains outdated, it could affect your search rankings and confuse visitors who find broken links. By ensuring that the slug matches the title, you’re making it easier for search engines to index your content correctly. Moreover, updated slugs that reflect keywords in the title can help improve your content’s visibility on search engine result pages (SERPs). This simple adjustment can result in better organic traffic over time.

Handling Custom Post Types and Excluded Post Types
While the function provided works well for standard posts, you may have custom post types on your WordPress site, such as products, reviews, or events. To ensure that the slug is updated for all custom post types, modify the condition in the function to check for additional post types. Similarly, if you want to exclude certain post types from having their slugs updated, simply adjust the logic to fit your needs. Customizing this function to handle specific post types can give you greater control over how slugs are managed across your website.
