As higher visitor engagement, retention and conversions are obtained through fast and optimised web pages, one needs to identify performance best practices that can be applied to his/her website. As studies show that users leave a website if it hasn’t loaded within 4 seconds, you need to keep your users happy and engaged by providing a fast performing website which is also good from a SEO perspective, as Google nowadays take into account the loading speed as a ranking factor. The following websites are meant to help you determine how fast your website really is and take the necessary actions to speed the loading of your pages:
1) PageSpeed Insights
Measures the performance of a page for mobile and desktop devices. The URL is being fetched twice: once with a mobile user agent, and once with a desktop user agent. The page score ranges from 0 to 100 points. The higher the score, the better. If you have a score over 85, it suggests that the page is performing well.
This tool measures how a page can improve its performance on:
- Time to above-the-fold load: Elapsed time from the moment a visitors requests a new page and to the moment the above-the-fold content is rendered by the browser.
- Time to full page load: Elapsed time from the moment a visitor requests a new page to the moment the page is fully rendered by the browser.
2) Pingdom Website Speed Test
It was built to help you analyze the load speed of your websites and learn how to make them faster. Tests are done with real test browsers from dedicated Pingdom servers to match exactly the end user experience. They use a bunch of instances of Google’s Chrome web browser to load websites, record performance data and so on.
- Performance overview – They automatically put together plenty of performance-related statistics for you based on the test result
- Performance grade and tips – See how your website conforms to performance best practices from Google Page Speed (similar to Yahoo’s Yslow). You can get some great tips on how to speed up your website this way.
- Trace your performance history – We save each test for you so you can review it later and also see how things change over time (with pretty charts!).
- Test from multiple locations – See how fast a website loads in Europe, the United States, etc.
- Share your results – They’ve made it easy for you to perform a test and share it with your friends, work colleagues or web host.

6) Gift of Speed

Has any of these websites helped you in particular to measure website speed? If so, please share your experience with us.
Thanks for this awesome list you’ve made of tools that would help measure website speed. And to think there were free ones too.
You’re welcome! There will be more posts about website speed definitely. I’m looking forward to release soon a free WordPress plugin to manage scripts and styles per page or all pages of the website to remove unused ones, thus having less HTTP requests which will make the website load faster and the HTML code will be cleaner and easier to read/scan 😉
Just wanted to say thank you for your amazing plugin. I’m not one to exaggerate, but on this occassion wish to show respect where it’s due. Anyone contemplating their next move on the optimization ladder need look no further than Asset CleanUp.
Caching plugins can only take you so far before they run out of gas. Asset CleanUp takes the baton and runs with it, obliterating every benchmark that acts the tough guy.
Overly dramatic? Well it would be if I weren’t simply telling the truth.
Thanks once again, Gabe, you have a plugin that deserves every one of its glittering reviews.
