Optimize WordPress Database Size in 5 Simple Steps
Before optimizing your WordPress database, take a complete backup first. If something goes wrong during the process, you can quickly restore your website.
Most hosting companies offer a backup feature, so make use of it before proceeding with the optimization.
Step 1. Disable And Delete Unused WordPress Plugins
Cluttering up your website with inactive or unused plugins takes up valuable storage space, which can drastically slow down your website.
To keep your WordPress site running smoothly, it’s essential to disable and delete unused plugins. With a few simple steps, you can free up valuable space on your server.
Plugins are one of the primary sources of security vulnerabilities on websites. By disabling and deleting unused plugins, you can protect your WordPress blog from potential attacks and protect your data from being accessed by unauthorized individuals.
Step 2. Delete All Spam Comments and Post Revisions
After deleting unused WordPress plugins, the second step in optimizing the WordPress database is deleting spam comments and post revisions.
To run your blog as efficiently as possible, you need to rid yourself of unnecessary clutter. This includes comments that are in your spam folder, as well as any post revisions.
You can ensure that your WordPress database remains optimized and speedy by taking these simple steps!
Step 3. Use cache plugins
The third step is optimizing the WordPress database.
One of the most common causes of WordPress slowness is outdated or excessive database files.
By caching your WordPress pages using a caching plugin like W3 Total Cache, you can significantly improve the performance of your website.
Step 4. Compress Images
With all of the new content created on the web, your website storage must be kept as lean as possible.
Compressing your images reduces the amount of data residing in your database, which saves your money on monthly hosting fees and helps to improve the performance of your website.
Step 5. Useful MySql Queries To Optimize WordPress Database
The Akismet plugin increases database size in many cases because of a table called wp_commentmeta. Install the WP-DB Manager plugin to run each SQL query separately from the WordPress dashboard.
DELETE FROM wp_commentmeta WHERE comment_id NOT IN (SELECT comment_id FROM wp_comments);
DELETE FROM wp_commentmeta WHERE meta_key LIKE '%akismet%';
The table name might be different in your WordPress installation, so check before applying the queries above.
