Speed matters, especially when it comes to retaining users’ attention online. Website visitors expect content to load in an instant, and as technology improves, the bar for “instant” gets higher and higher. Still, many websites still underperform when it comes to loading times.

One potential reason for slow loading speeds is a poorly optimized database. The database is the digital archive for all your important information, from posts and pages to user data and settings. However, over time, it can become cluttered with unnecessary data like spam comments, post revisions, and digital debris. This spare data (like deleted posts, stored revisions, and orphaned metadata from deleted plugins) takes up space and slows down your site’s performance. As the database bloats, your site’s load time increases, leading to frustrated visitors, higher bounce rates, and a hit to your SEO rankings.

This can be devastating for your website since one measly second can make or break a website user’s experience. Research from Thinking With Google shows that a one-second delay in mobile load times can slash conversion rates by up to 20%.

Fortunately, a tidy database can help your website keep up. In this guide, we’ll cover your WordPress database and the tools needed to declutter, optimize, and improve your site’s performance.

Three Ways to Optimize Your WordPress Database

No matter how you optimize your database, there’s always a risk of removing valuable data your website needs. With a fresh database backup, you’ll have a failsafe mechanism to restore everything easily.

Creating this backup is simpler than you think, and it’s even more straightforward if you’re a Pressable user! Here’s how to run an on-demand backup using the MyPressable dashboard:

1. Log in to your MyPressable account.
2. Go to the site you want to back up.
3. In the site management section, find the Manage Data option.
4. Select On-demand Backups from the menu.
5. Click on Create Database Backup.

Now that your data is protected, you can focus on database optimization. We’ll explore three methods: via a plugin, using WordPress’s Repair Database function, and manually optimizing your database via phpMyAdmin. Each method caters to different skill levels, but both promise to speed up your site and remove excess or unused data.

1. Low-Tech Approach Using a Database Optimization Plugin

For business owners who want to optimize their WordPress databases without the technical hassle, plugins offer an accessible and effective solution. These tools are particularly valuable for those who might not feel comfortable diving into website files or database management. By using a plugin, you can streamline the optimization process and maintain your site’s performance with minimal effort.

When searching for a good database optimization plugin, it’s important to conduct thorough research. Here are some steps to help you choose the best plugin for you:

• Check Reviews: Look for plugins with high ratings and positive feedback from users. Reviews can provide insights into the plugin’s reliability and effectiveness.
• Explore Online Discussions: Visit WordPress forums, message boards, and social media groups to see what others are saying about various plugins. This can give you a sense of common issues or standout features.
• Verify Active Development: Ensure the plugin is still actively maintained by its developers. An actively developed plugin will be updated regularly to fix bugs, patch security vulnerabilities, and stay compatible with the latest version of WordPress.

Two highly recommended plugins for database optimization are WP-Optimize and Advanced Database Cleaner. These plugins are user-friendly and packed with features to help you maintain a speedy and efficient WordPress site.

WP-Optimize plugin highlights:

• Database Optimization: It cleans and optimizes your WordPress database by removing unnecessary data, such as post revisions, auto draft posts, trashed posts, spam, and trashed comments. This feature helps to speed up your site and save server resources.
• Scheduled Cleanups: Set up automatic cleanups to run at regular intervals (daily, weekly, fortnightly, or monthly) to ensure your database stays optimized without manual intervention.
• Flexibility and Control: With the premium version, you can optimize select individual tables or a particular combination of tables on one or more WordPress websites, giving you greater control over your optimization process.
• Power Tweaks: WP-Optimize offers unique power tweaks, such as a turbo boost for WooCommerce that replaces slow queries with more efficient ones, and an option to boost performance by indexing the postmeta table.

Advanced Database Cleaner plugin highlights:

• Comprehensive Database Cleanup: Remove old revisions, spam comments, and orphaned metadata.
• Scheduled Optimization: Automate cleanup tasks to run at specific intervals.
• Database Table Management: Optimize and repair tables for efficient performance.
• Multisite Support: Clean up and optimize databases across your entire network.
• User-Friendly Interface: Easily view and manage data to be cleaned up.

Both WP-Optimize and Advanced Database Cleaner simplify the process of database optimization, making it accessible even for users with limited technical knowledge. By using these plugins, you can enhance your site’s speed and performance, ensuring a better experience for your visitors.

2. Using an SFTP Client and WordPress’s Automatic “Repair and Optimize Database” Function

WordPress offers a built-in database repair and optimization solution through its Repair Database function, accessible via a tweak to your wp-config.php file. This method provides a quick and automatic database update, ensuring the safety of your WordPress files and preventing accidental deletion of vital data.

However, it’s important to note that while this process is fully automated and relatively straightforward, it may not work when making granular changes to your database.

Here’s a step-by-step guide to using this method:

1. Connect to your website’s server via an SFTP client such as FileZilla or CyberDuck.
2. Download the wp-config.php file located in your WordPress website’s root directory.
3. Open the file with a text editor and locate the line that says:

/* Add any custom values between this line and the "stop editing" line. */

4. After that line, add the following code:

define( 'WP_ALLOW_REPAIR', true );

Remember, remove this code to prevent unauthorized access to the repair and optimize the screen.

3. Manually Via phpMyAdmin

phpMyAdmin lets users automatically optimize their site and perform manual, granular optimizations.

Accessing your site’s database might seem daunting, but it’s simple for Pressable users, who can access phpMyAdmin from the MyPressable control panel.

Here’s how to optimize your database via phpMyAdmin:

1. Go to your website’s phpMyAdmin. Pressable users can do this by logging into the MyPressable control panel and selecting the button on the top right of the screen.
2. In phpMyAdmin, go to the Database tab and select the site’s database.
3. Use the checkbox to select all of your WordPress site’s tables.
4. From the dropdown menu, choose Optimize tables.
5. Once you’ve selected, phpMyAdmin will execute the optimization process and provide a message indicating the status.
6. When finished, you’ll receive a message confirming that your SQL query has been executed successfully.

How to Reduce Database Bloat in the Future 

It’s important to implement strategies that prevent database bloat over time to sustain website performance and speed.

Here are some steps you can take to reduce database bloat and enhance overall site efficiency:

1. Regular database cleanup: Establish a schedule for cleaning your database based on your site’s activity level. High-traffic sites with frequent updates may require weekly cleanups, while average WordPress sites can suffice with monthly maintenance.
2. Comprehensive data removal: Deleting old posts, pages, or media files isn’t enough. Follow up with database optimization to remove orphaned metadata and optimize table overhead, ensuring no unused data remains in your database.
3. Limit post revisions: Configure WordPress to limit the number of post revisions stored, effectively curbing database bloat from accumulating over time.
4. Offload resource-intensive tasks: To keep the database lean and nimble, consider using external services for resource-intensive tasks, such as video hosting with VideoPress.
5. Remove unused plugins and themes: Regularly review and remove inactive or unnecessary plugins and themes, as they can leave behind database entries that contribute to bloat.
6. Prioritize regular backups: Always perform a backup as a safety net before making any major changes. Pressable’s automated and on-demand backup feature makes it easy to revert changes if needed.
7. Adhere to best practices: Go for less resource-intensive plugins, avoid bulky page builders, and conduct regular site content and structure audits to ensure efficiency and minimize database strain.
