After successfully improving speed on many websites, I’ve noticed a pattern in the tools we use. Thus, I’ve decided to write an article explaining the best WordPress speed optimization plugins available today.

As you may know, speed optimization is critical for every WordPress site. From user experience to SEO rankings, every second counts.
Ironically, the main thing that makes website slow in the first place, can propel it to its fastest boundaries – plugins.

With the help of plugins you can ensure the easiest way to keep your site lightning-fast. But you should have their number down to a minimum (a high plugins number will slow your website down), so it’s essential to choose the right ones.

And here my speed optimization expertise kicks in.
Whether you’re looking to cache, optimize images, or control assets, these plugins have proven their worth in many speed optimization projects I’ve completed so far.

Here’s a roundup of the 10 best WordPress speed optimization plugins grouped by their purpose, so you can optimize every aspect of your site.
Furthermore, on their headlines, I’ve outlined are they free or paid, for your convenience. All of this makes this article 10 Best WordPress Speed Optimization Plugins list at the date.
