Best Database Optimization Plugins for WordPress

Having a slow WordPress or WooCommerce website is not good. It can affect your overall revenue, ranking, and conversion rates. This post is for you if you want to optimize your database to improve your site’s performance. This article will show you the best database optimization plugins for WordPress to help optimize your WordPress site for better performance.

But first, let’s see why we need to optimize our database and how an unoptimized database slows down a website. Let’s have a look.

Why Database Optimization Is a Must

Database optimization is a must if you need to increase the speed and performance of your WordPress website.

In 2018, Google said it would use website speed as a ranking factor. So if you have great content but a slower website, you won’t rank higher than your competitors.

To cater to that, there are several techniques known for speeding up a website, like choosing the best WordPress hosting, using a lightweight theme, using well-coded plugins, compressing images, minifying static files, etc.

But most people usually forget about database optimization at all.

Remember that it is the database that holds our website’s content and stores them securely. So when a visitor lands on any blog posts, your web server will fetch content from the database. If the database is bulky, the process will take more time, and the loading time will be high.

On the other hand, an optimized database will help you speed up the loading time and have a good experience.

What Causes Your Database to Slow Down

Multiple things can affect your database. A few things you need to note are:

  • Unused WordPress Themes and Plugins
  • Post Revisions
  • Spam Comments
  • Trashed Posts
  • Trashed Comments

We will take a quick look at each option before moving forward.

  • Unused WordPress Themes and Plugins: You can activate only one WordPress theme at one time. So, no point in keeping multiple themes installed as it will only bloat your website. Instead, delete them to increase disk space and performance. Similarly, you can also delete unused WordPress plugins from your website.
  • Post Revisions: When you update your posts, pages, or custom post types, WordPress will save a revision of the old version. This won’t be required in most cases. So, limiting the revisions or clearing them from the website will help you boost your performance.
  • Spam Comments: Using a tool like Akismet, you can automatically filter all spam comments. But keeping them on your WordPress website is not ideal. You have no use for spam comments. So, deleting them would help you optimize the database.
  • Trashed Posts: There can be multiple reasons to trash a post. But keeping the trashed posts on your WordPress website is not a good practice as it fills up your MySQL database.
  • Trashed Comments: Trashed comments are also an unwanted load and can affect your database negatively.

So, to help you with database optimization, there are several dedicated WordPress database plugins. Using a plugin will make your job easier to clear everything you do not need in your MySQL database.

Things to Look for in a Database Optimization Plugin

When choosing a database optimization plugin for WordPress, make sure to check these things:

  • Ease of Use: Is the plugin easy to use, or is any additional technical knowledge required?
  • Features: Are they dedicated to database optimization only? Or do they offer any additional optimization features?
  • Support: Do they provide support if you need help with the plugin?
  • Security: Are the plugins receiving regular updates and security patches?

Well, we researched for you and found the best plugins you can rely on.
