15 of the best website speed optimization tools to use in 2024

Website speed touches everything that contributes to your website’s success, including SEO, user experience, conversion rates, and other performance metrics. Most importantly, a high website speed is crucial because users don’t want to wait around for websites to load. 

The average page load time is about 1.65 seconds. When this rises to 3 seconds, studies show that it increases the bounce rate by 32%.

In other words, 1 out of 3 website visitors will leave without converting or checking out other pages. On top of that, search engines prioritize fast-loading websites because search engine bots can quickly crawl through them. 

With the website speed optimization tools discussed in this article, you can boost your website’s speed and enjoy a higher conversion rate, SEO ranking, and more site visitors.

So whether you’re a site owner, admin, web developer, or digital marketer, here are 15 website speed optimization tools you can use to analyze and boost website speed.
