To gain all the benefits that comes from having a fast website, below are some of the best tools to use.


Uptrends allow testing from over 35 different locations. The final report will give you an assessment by domain group as well as a waterfall breakdown (waterfall charts helps you to visualize the cumulative effect of sequentially introduced positive and negative value). This domain group then goes into further details hereby putting the resources into different categories (e.g advertisement, third party, social media and so on.) Meanwhile, the Waterfall Analysis enables you to determine exactly what elements in your site are causing the greatest delays. It inspects HTTP headers per element, making it easy to analyze root causes. The Uptrends package comes with social media scripts, content delivery network performance check, user analytics and analysis of video player embed. Uptrends offer monitoring for the website itself, web applications, websites on mobile devices and for internal/external servers. It comes with a 30-day free trial.

Google PageSpeed insights

Google PageSpeed Insights happen to be one of the best tools out there for carrying out website performance check. This service grades your sites from the range of 1-100, with above 85 considered as good. PageSpeed measures two things—the time of the above-the-fold load (i.e, the amount of time it takes for the upper part of the page to load) and time of full page load. There are desktop and mobile versions of this tool. On mobile reports, there’s a User Experience tool (which is currently in Beta) showing what specific item needs to be addressed and how, and it offers context to why they need to be addressed to improve the mobile user experience. Google PageSpeed Insights give a total picture of the site speed as well as recommendations (e.g image change) on how to improve it.
