Make a backup of your database before installing any database maintenance software or performing any other type of cleanup.

Computer systems have their own minds, and the last thing you want is to lose your important data because you were in a rush to improve it.

The more plugins you have installed on your WordPress site, the longer it will take to load, depending on whether it is front-end or back-end. Front-end plugins add more JavaScript and CSS files to your website, slowing it down and taking up database space.

This is due to the fact that each plugin is a separate line of code that a browser must load when a page is loaded. Webmasters frequently forget to delete unused plugins. As a result, their website becomes bloated.

Searching for and deleting unused/disabled/unnecessary plugins is one of the best ways to declutter your WordPress database.

If you’re like most people, you enjoy trying out new plugins, and it’s likely that you’ll forget to delete the majority of them. You may also end up installing plugins that perform the same function.

In any case, it’s a good idea to spend some time going through your plugin list and deleting the ones you never use. To save space or take up less space in the database, you should remove unused plugins or replace them with better options. This is one of the most important things you should do in order to keep your database clean.

You don’t need to install any plugins to optimize your database. You can easily optimize your database tables to get more from them with just a few clicks. Click on the database in phpMyAdmin, then scroll to the bottom of the page.

Select ‘Optimize Table’ after checking the ‘Check All’ box. If you have multiple pages of tables, you will need to do this again. If you have a large website, the process may take longer. You will, however, receive a success message at the end of it all.

5. Clear Comments are currently being moderated

Clear Comments are currently being moderated

The type of comments that appear on your website must always be moderated. However, if the majority of the comments you receive are spam and you don’t have time to weed through them all, you can use a simple query to delete all pending comments.

However, before using this query, it is always a good idea to read the comments to see if they are genuine.

DELETE FROM wp_#_comments WHERE comment_approved = ‘0’;

Replace ‘#’ with the target site ID once more.

6. Spam Comments Should Be Removed

Allowing your audience to comment has its drawbacks, one of which is that you will always have to deal with spam.

This could be in the form of negative comments or promotional content from online marketers. The good news is that there are queries that can assist you in quickly removing spam comments.

DELETE FROM wp_#_comments WHWRW comment_approved = ‘spam’;

All you have to do with the above query is replace the ‘#’ with the site ID you want to clean up of spam comments.
