The tools should include multi-location during the test

The Internet at different locations is not the same and that’s why multiple geographic locations should be considered. The loading of a website in Viet Nam must be different with the one from a country in Africa.

The tools should consider the page performance on mobile

The tools use web’s search engine giants

Yahoo’s YSLow and Google Page Speed should be used to rank the website performance. As you see, they are the two biggest search engines nowadays and it’s necessary to check your site’s speed with them.


Based on the features above, we pick out some best tools for you. Let’s see and choose one for your site.

Google PageSpeed Insights

Google PageSpeed Insights is a product of Google Team that can help you to measure the performance of a page for both mobile and desktop devices.

It ranges from 0 to 100 points, and the higher score is better. 85 or above indicates that your page works well.

PageSpeed Insights measures how the page can improve its performance on:

  • time to above-the-fold load: Elapsed time from the moment a user 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 user requests a new page to the moment the page is fully rendered by the browser.

Personally, this is a great tool which can not only show you the error but also give us recommendation to fix it. You can refer to About PageSpeed Insights for more information.


Pingdom is one of the best popular tools for web performance checking that can help you not only check the website’s uptime, performance but also the interactions.

Different from the Google PageSpeed Insight, this GTmetrix grades your site from F to A. In addition, thanks to its report, you will have full picture about both your site’s performance and the inner workings.


WebPageTest is also a very good choice for you. It has over 40 locations to choose from and over 25 browsers including mobile for you to test your site.

This tool also rates the performance for F to A and show your site’s work into summary, details, performance review, content breakdown and screenshots sections.

Especially, this tool provides you great feature such as video capturing, disabling JavaScript, ignoring SSL certificates and spoofing user agent strings.
