Best plugins to clean up and optimize WordPress database and tables

A database is a structured set of data which stores different kinds of information. Before you can even install WordPress, you will have to create a database (or software will do to that for you if you’re installing WP from cPanel, for example). By default, WordPress needs eleven tables in that database to store viable parts of your future posts, taxonomies, users, comments, etc.

Once you start upgrading your site with new plugins and themes, the number of tables keep on rising and the database keeps on getting larger and clunkier. On one of our local servers that we use for testing themes and plugins, we found more than seventy tables! Imagine how much tables are on your hosting server if you have been using WordPress for years.

Most users get aware of that only when they experience a slower site. The problem gets even bigger if you tend to install numberless themes and plugins. Unfortunately, even if you deactivate and delete most of the themes and plugins, they will leave the unnecessary tables in your database. And before you know, you can get up to a hundred tables which slow you down. Before you get to that, you should always keep in mind that WordPress needs maintenance. Just like you would optimize your computer hard drive or photos that you put on the web, you should clean up and optimize WordPress database from time to time.

Don’t worry; although a word “database” might sound terrifying to someone who has no experience with coding (and believe us, it may become even more terrifying when you start working with queries on a regular basis), cleaning and optimizing WordPress database isn’t that hard. In this article, we’re about to show you how to quickly defragment a database with phpMyAdmin. Then, we will show you some of the best WordPress plugins which will clean up and optimize WordPress database in just a few clicks.

Quickly optimize WordPress database with phpMyAdmin

While you’re using WordPress, you might not even be aware of the processes going on in the background. Queries to the databases run like mad, tables come to existence and they get deleted, fields keep on changing on a daily basis. If you’re just using WordPress to write your blog, you don’t even have to think of all that, but the truth is that every action fragments the database and new information makes it slower to load. By looking for pieces to complete new tasks, everything becomes slower and you just have to clean up and optimize WordPress database.

Quickly optimize a WordPress database with phpMyAdmin

Before we start with the list of plugins, let’s quickly see how to clean up and optimize WordPress database manually. This might come in handy from time to time so it won’t hurt to remember this simple process.

Before you start fiddling with the database, make sure that you create a WordPress backup.

  1. Log in to your cPanel
  2. Navigate to Databases category
  3. Open phpMyAdmin
  4. Choose your WordPress database on the left side
  5. Scroll down under the list of tables
  6. Click on the Check All button
  7. From the “With selected” list, choose Optimize table

Even if you have a larger number of tables, the process shouldn’t last more than several seconds. Some tables will be successfully optimized, while some may be skipped, but you shouldn’t worry about that. You’ve just successfully optimized your database.

Best plugins to clean up and optimize WordPress database

Even though you can quickly defragment a WordPress database through phpMyAdmin, there are some fantastic WordPress plugins which can do a much better job. First of all, you won’t have to manually search for the database nor the tables. Secondly, the plugins will give you extra options that will help you do a much better clean up.

Before running any of the plugins for the first time, it’s crucial that you create a WordPress backup or choose one of the best backup plugins.
