Regularly cleaning up your database improves site performance and reduces storage use. This guide covers steps to optimize your WordPress database using plugins and manual methods.

Method 3: Manual Cleanup via phpMyAdmin (Advanced Users)

If you prefer a manual approach or have specific cleanup needs, you can optimize your database directly in phpMyAdmin.

1. Log into phpMyAdmin

   • Access phpMyAdmin from the Shared Hosting Control Panel.

2. Select Your WordPress Database

   • In phpMyAdmin, choose your WordPress database from the left sidebar.

3. Optimize Database Tables

   • Scroll through the list of tables and select the ones you wish to optimize (e.g., wp_posts, wp_comments).
   • Scroll to the bottom, select Optimize Table from the dropdown, and click Go.

Caution: Always back up your database before making manual changes, as incorrect changes can lead to data loss.

Additional Tips for Database Maintenance

• Back Up Regularly: Before performing a cleanup, always back up your database. If anything goes wrong, you’ll have a safe restore point.
• Set Up Scheduled Optimization: Many plugins, like WP-Optimize, allow you to schedule automatic cleanups, keeping your database efficient without regular manual intervention.
• Review Plugins Carefully: Certain plugins can bloat your database over time. Periodically review your active plugins and remove any that are no longer necessary.
