The best website speed test tools can help you to speed up your webpages to better help users and search engines.

Website speed tests have become increasingly important for marketing, and web development. While there was always supposed to be understanding that it was better to load up your website fast for users, this hasn't always been taken on board by website developers.

Even in the age of the dial-up modem, some web developers still insisted on large images that could take time to load. And the arrival of high-speed broadband has allowed lazy web development to focus on bloating code, rather than the user experience. 

This in itself could be a problem when it comes to marketing, but it's also become an issue in search engine optimization (SEO) because search engines such as Google now take into account page loading speed as a ranking metric. In other words, it your targeted webpage takes a long time to load, Google will preference competitor webpages that don't.

This has caused another resurgence in interest for optimizing the page loading speed of websites. While there are plenty of developers who have always kept to best practices, everyone is now under extra pressure to deliver on page loading time savings - or risk losing important web traffic through search engine results.

We've compared these tools across various points, from the simplicity of their user interface and steepness of the learning curve to their overall performance and the quality of site analysis. We also assessed their diagnostics and performance suggestions and considered their pricing models, among other things.

Here therefore we'll list the best website speed test tools, to ensure you're giving the most for your user experience.

What is a website speed test tool?

A website speed test tool helps to evaluate and pinpoint what aspects of a site are causing a slowdown in the loading times. It analyzes the total load time, the load speeds from multiple server locations, the HTTP headers, etc. 

A website's loading speed is a vital factor that influences the site's traffic. The  slower the loading speed, the more likely visitors are going to leave the website.

Advanced tools will offer opportunities to improve the page speed loading times, and it'll help if you opt for a tool like that. Tools that provide comprehensive diagnostics will help you pinpoint specific areas that need improvement.
