How to Optimize Your WordPress Database?

Have you ever wondered why a WordPress website performance decrease with time? A lot depends on the WordPress databases, which is the storehouse of all website content. In this article, we will understand how the database works and the steps you can take to optimize the database.

Understanding WordPress Databases

Before you start optimizing your website database, let us understand the fundamentals of WordPress database tables.

Below is the screenshot of a tabular WordPress site structure. WordPress only supports MySQL 5.0.15 or greater or other versions from MariaDB for its database. The diagram explains the database and relationship between its tables which originated during WordPress installation.

The fundamental WordPress database tables shown in the diagram helps to store post tags and categories, blogroll links, description about taxonomy, users, post meta information and much more.

Importance of Optimizing WordPress Database

As mentioned previously, WordPress works with MySQL database, which is further supported by PHP programming language. PHP is used to analyze and render the information saved in the MySQL database. MySQL is the source technical infrastructure behind every WordPress installation, containing all the necessary data bytes about the WordPress site.

A basic WordPress installation has eleven tables. However, when you create or install new themes or plugins, the database creates new tables to save the information. While changing or removing plugins and themes, a lot of information is left behind in the database. Whenever you revise a post, WordPress database additionally creates a draft version, and as the inessential information pile up, the database becomes huge, and without proper database maintenance, the website speed decreases.

As we know, a slow site is not good for an online business. By optimizing and clearing your WordPress database, you can lessen the site loading time and create extra space for user data storage.

Manual Database Optimization

Can you optimize your database without a plugin?

 Although plugins do make the optimisation work much easier, you can also optimise your site database manually. Follow the steps mentioned below to clean your database without plugin:

  • Login to your hosting account and navigate to cPanel.
  • Under the list of tools, you will see “PHPMyAdmin”. This section allows you to edit and preview your site MySQL database manually.
  • Go to the “Table” column. You will see all the tables related to your database. On this screen, you will be able to check the space each table is occupying.

If you are not good with coding, you may find PHPMyAdmin confusing. Before deleting any table, go through each table and identify the information you want to remove. Remember, a small mistake can remove your site’s valuable information. Be careful with the “Drop” link, as it will permanently eliminate a table and the data saved inside the table.

Once you are sure about the data you want to delete, enter the required MySQL commands to remove it.

If you are not accustomed to MySQL, opt for automatic site optimisation through the above-mentioned plugins.

Endnote

Before using any database management plugin, make sure to take a full site backup. If anything goes wrong, you can retrieve the backup and get the site back easily.
