20 Free Online Tools for Website Speed Testing

We all should be aware by now that Internet users are impatient when it comes to waiting for a web page to load. Thus, your website’s performance and ability to render speedily is critical to its usability and, ultimately, its success. Site speed not only hurts user experience but it also has a direct impact on SEO so it doesn’t matter if you are an auto parts retailer or a school, it should be something you monitor.

In order to help you build faster websites and identify troublesome website performance bottlenecks, consider incorporating some of the following tools into your web development process.

Tip: It might be a good idea to use several of these website speed-testing tools so that you can obtain a better picture of site speed issues. Heck, they’re free, so why not?

1. Page Speed Online

Google’s Page Speed Online — which is a web-based adaptation of the popular Google Chrome web development browser extension, Page Speed — analyzes your website’s performance under Google’s Web Performance Best Practices (a set of rules for optimal front-end performance). You can gain lots of information from this handy web tool – it even includes a report for mobile device best practices for optimal performance.

2. Pingdom Tools

This free online website speed-testing tool by Pingdom (a server, network and website monitoring service) provides you with several reports such as a breakdown of how long each web page object (e.g. images, style sheets and JavaScript libraries) takes to download and performance grades for things like browser caching.
