Faster loading websites benefit from higher SEO rankings, which directly affects higher conversion rates, overall user experience, engagement and low bounce rates. There are plenty of free tool available out there , that can help you test and boost your website speed. Before we go any deeper, here are a couple of pointers on what to do with website speed test tools:

  • Testing Time to First Byte (TTFB)
  • Analyzing total load times, page sizes, and # of requests
  • Checking performance from different geographical locations
  • Checking minification of your scripts
  • Finding large images resulting in bottlenecks

  • Verifying that assets are loading correctly from your CDN
  • Determining if you have render-blocking JavaScript or CSS

It is also important to realize when running tools like these that a 1st time DNS lookup will usually be slower. If you are comparing total load times it is sometimes better to run tests multiple times and take an average of the results.

Here are the top 7 free tools you can use to optimize the speed of your website:

1. WebPageTest

WebPageTest is great too but it has one distinctive advantage – it has over 40 locations to choose from and over 25 browsers (including mobile). If you click on “Page Speed” after running a test you’ll find an overall grade as well as a checklist of some suggested changes (in order of importance) for increasing your website’s speed. It assigns you a grade from F to A based on different performance tests. It’s report is divided into six sections which include a summary, details, performance review, content breakdown, and screenshots. One cool feature of WebPagetest is the ability to select the country from which to run your test. This can be used to track how your speeds vary across the world.

Another great free tool from Google. It’s extremely simple to use and you can launch it anytime in your Chrome browser. They’ve recently added an aggregated details panel into the waterfall timeline.

This goes one more time – testing your mobile is crucial. Since mobile is taking over, optimizing your mobile web into a fast and responsive website is a key factor. Another way to simulate a speed test on a mobile device is to use Chrome developer tools in device mode. To enter device mode click on the small phone icon in Chrome DevTools or you can press Ctrl + Shift + M (Cmd + Shift + M). You can then choose what device you want to emulate, the orientation, and even resolution. You can also change the network throttling to see how your website actually would render on say a regular 2G or 4G connection.

This little insight helps you see how well your mobile web does in bad connection conditions. Getting an A on this test will surely reduce the bounce rate a lot. Web speed and optimal mobile browsing experience are everything these days – don’t wait too long to optimize too late.
