In the ever-evolving world of web development, speed and performance are crucial. Wordpress, as one of the most popular content management systems, powers millions of websites around the globe.

Indeed, there are numerous WordPress development tools you can count on to enhance its efficiency. But at the core, its Database optimization is a must to get the site running smoothly and ensure a positive user experience.

This database is where all data, including usernames, passwords, posts, and comments, get stored. As such, by optimizing the Wordpress Database, you can ensure increased website speed and overall performance.

Fortunately, there are various methods to achieve an optimal WordPress database. In this blog, we will go through the best two methods to conduct so. First, by using the WordPress Database optimization plugin and then via ‘phpMyAdmin’, which is a bit advanced method and mostly suggested for experienced technoids.

Understanding WordPress Database

The WordPress Database is a fundamental component of the WordPress content management system (CMS). It serves as a structured repository of data stored within a MySQL database management system.

This database plays a pivotal role in managing and organizing various data types that collectively constitute a WordPress website. One of the primary data categories stored in the WordPress database is content.

WordPress database contains all the textual and multimedia elements added to your website, including posts, pages, custom post types, and their associated attributes like titles, content, publication dates, categories, and tags.

Furthermore, the database also houses user-generated queries. When a web visitor visits the website – the web browser requests the server to transmit the necessary data required to display and run your content.

Each new piece of information added to the WordPress site will gradually occupy your database size. You can also carry out these commands manually or via a database manager.

Introduction to WordPress Database Table

Structurization is something that can make each content and its navigation well-formatted.

Following the same, the WordPress database also includes containers within that store specific types of data related to your website’s content, configuration, and user interactions.

Here’s a brief explanation of some common WordPress database tables:

1. wp_posts: This table stores essential information about WordPress posts/pages, and even custom post types. It includes attributes such as content, titles, authors, and publication dates.
2. wp_comments: Responsible for managing user comments in WordPress, this table stores data about comment authors, text, timestamps, and other relevant comment details.
3. wp_users: User-related information is stored in this table. It includes usernames, email addresses, hashed passwords for security, and user roles.
4. wp_options: Site settings and configuration data are stored here. This includes settings for themes, plugins, and general site options.
5. wp_terms and wp_term_taxonomy: These tables are used to categorize and organize content through taxonomies like categories and tags.
6. wp_postmeta and wp_commentmeta: These tables store metadata associated with posts and comments, respectively.
7. wp_links: Historically used to manage website links and blogrolls, this table has become less relevant in modern WordPress sites.
8. wp_commentmeta: Similar to post meta, this table stores metadata associated with comments.
9. wp_termmeta: It authorizes the storage of additional information about categories and tags.
10. wp_term_relationships: This table defines the relationships between terms (categories and tags) and posts. It specifies which posts are associated with specific terms.
11. wp_term_taxonomy: This table stores information about taxonomies, including the hierarchical structure of categories and the relationships between terms and taxonomies.
12. wp_usermeta: Similar to post and comment meta, this table stores metadata associated with users. It’s often used by plugins and themes to store additional user-related information.

Understanding these database tables is essential, especially when it comes to database optimization and troubleshooting issues on your WordPress site. Each table plays a specific role in managing and organizing your site’s data, ensuring its smooth operation.

Measures to Optimize WordPress Database

Great, that you learned ‘How to Optimize WordPress Database‘ – with both the methods of using and without using a WordPress plugin for database optimization. But taking timely measures is as important as that – here are several must-add measures for your index:

1. Optimize Media Files

When it comes to database optimization, by including media files such as images and video WordPress media library plays a vital role. The files included in this library can accumulate over time and take up a significant amount of storage space.

To optimize them, consider using image compression plugins such as EWWW Image Optimizer, ShortPixel Image Optimizer, and WP-Optimize which can automatically reduce file sizes while maintaining image quality.

2. Manage Post Revisions

WordPress automatically saves revisions of both posts and pages as you work on them. While this is useful for tracking changes, it can result in a bloated database.

To limit post revisions, you can add code to your wp-config.php file to define the number of revisions stored, reducing the database’s size and improving performance.

3. Monitor Database Queries

Understanding how your website interacts with the database is crucial for optimization. Plugins like Query Monitor can help you out for keeping a close watch on database queries. It helps you identify slow or resource-intensive queries. Once identified, you can work on optimizing them for better performance.

4. Consider Content Delivery Networks (CDNs)

CDNs are networks of servers distributed across various geographic locations. They can clear WordPress cache and serve static content like images, CSS, and JavaScript files from servers closest to your website visitors.

By offloading this content to CDNs, you reduce the strain on your primary server and the database, resulting in faster content delivery and improved user experience.

5. Delete Unnecessary Plugins and Themes

Over time, websites tend to accumulate unused plugins and themes. These not only occupy valuable server space but can also introduce security vulnerabilities.

To prevent multiple themes on your WordPress dashboard, you can consider creating a child theme. By the time, to keep your database streamlined – you should also regularly review and delete unnecessary plugins and themes.

6. Delete Pingbacks and Trackbacks

Pingbacks and trackbacks are features that notify your site when another site links to your content. While they can be valuable for engagement, they can also create unnecessary database clutter.

By regularly reviewing and deleting old or spammy pingbacks and trackbacks, you maintain a more efficient database and prevent the accumulation of irrelevant data. This practice contributes to a streamlined and responsive website experience.

You can do this by heading to Settings > Discussion in WordPress, and deactivating the first two settings:

7. Implement Caching

Caching is a technique that temporarily stores web pages and their elements, reducing the need to repeatedly generate content from scratch.

By implementing caching, you can significantly improve page load times, reduce server load, and optimize your database’s performance.

8. WordPress Transients

Transients are a form of temporary data storage in WordPress. They are often used to store and retrieve cached data. However, poorly managed transients can accumulate and bloat your database.

It’s essential to regularly review and clean up transient data to prevent database clutter and improve website efficiency.

9. Remove Spam Comments and Revisions

Spam comments and multiple post revisions can bloat your database. As a prevention, you should regularly delete spam comments and limit the number of post revisions stored. Considering Plugins like WP-Optimize or WP-Sweep can be a great adorning to conduct this.

10. Remove Spam Comments and Pages/Post Revisions:

Spam comments and multiple post revisions can bloat your database. As a prevention, you should regularly delete spam comments and limit the number of post revisions stored. Considering Plugins like WP-Optimize or WP-Sweep can be a great adorning to conduct this.

Remove Pages/Post Revisions

WordPress database diligently records revisions of all your posts and pages, offering a useful history for content tracking and rollbacks. However, as your content evolves, these revisions can accumulate, potentially leading to database clutter.

One effective approach is to consider controlling the number of post revisions WordPress stores. By implementing this, you can maintain a well-organized database and prevent it from becoming overcrowded.

To get started, access your wp-config.php file via FTP, and insert the following code:

Alternatively, if you prefer to disable post revisions altogether, you can use this code:

Remove Spam Comments

Eliminating spam comments from your WordPress site is essential for two key reasons.

Firstly, over time, accumulating spam comments can negatively impact your database and overall site speed. Moreover, they create a poor user experience and may deter genuine users from engaging with your content.

While WordPress will eventually delete spam comments after 30 days, they can still occupy your database during that period. You can swiftly delete these unwanted comments by selecting and using the ‘Empty Spam‘ button.

Furthermore, many anti-spam WordPress plugins, such as Akismet, offer the convenience of automatically filtering and permanently removing spam comments from your database.

11. Reduce Database Overhead

Including the redundant data can accumulate overhead in the WordPress database. There are multiple aspects that get involved in it such as post revisions, spam comments, and transient options. To minimize it you can run manual SQL queries or through plugins such as WP-Optimize.

12. Limit External Requests

External requests from your website to external services, such as social media platforms, analytics tools, or external APIs, can slow down your site’s loading times.

Limiting external requests involves optimizing your website by reducing or consolidating these requests. This enhances the user experience and decreases the load on your database and server, resulting in faster page loading and better performance.

13. Take out the Trash

However, deleted items don’t disappear from your database immediately. They will be posted in your website’s trash folder for 30 days. If you delete many items regularly, you might want to consider emptying your database’s trash more frequently.

Note that this is a core file for your WordPress website. As such, you’ll want to save a backup before you make any changes to it. Then, access your site via File Transfer Protocol (FTP) and open the wp-config.php file with your text editor.

Finally, add this code to the file:
