Cleanup and Optimize Your WordPress Database

WordPress is no doubt the most popular CMS with the biggest supporting community. If you are thinking of creating a website and don’t know which CMS to choose, you can go ahead and install WordPress without giving it a second thought. With an ever-growing number of free (and premium) plugins and themes, you can do almost anything with WordPress easily.

But if you are owner of an already running WordPress blog, you might have faced issues of database performance. One of the main cause for this problem is a cluttered database. Without proper optimization, your database can get a lot of unnecessary comments (spam), too many post revisions and other data that might never be used and does nothing but to increase the size of your database. If you are also worried about this issue, then keep reading for some very easy methods of cleaning up your database.

There are 2 main methods: first is using plugins and second is by manually cleaning database using database management tools like PHPMyAdmin. The latter gives you more control but is a bit risky and not recommended for ordinary users. Here we will focus on the first method since it is better suited for most users.

IMPORTANT: it is highly recommended that you back up your database before proceeding, though not a must. In case you run into any problems or remove any important data accidently, it is very relaxing to have a backup.

2. WP Optimize

WP Optimize is another useful plugin. It can also clear up all sorts of junk including trashed posts, spam comments and auto-drafted versions of your posts. It also offers scheduled cleanups which are completely user-customizable and makes the whole process automated and much easier.


The interface is nicer compared to other similar plugins and gives quite good control over all the necessary features a beginner or a novice user might need. There are ads on the plugin’s main page so if you are someone who hates them for any reason, you might want to check other options.

3. WP-DBManager

WP-DBManager, as the name suggests, is a database management plugin that is both powerful and very useful for optimizing WordPress database. You might already know that WordPress uses an SQL database to manage all of the content and thus, database is considered the
backbone of your website. With a poorly managed database, your website can run into problems and become very slow.

WP-DBManager is great for those who prefer more features like custom SQL query execution and database backup. So choose the one that appeals you most based on the features you specifically need.
