GTmetrix for Site Speed (Free)

This is a completely-free, but incredibly indispensable blogging tool.

Of course, you’ll potentially lose a lot of money if your website is so slow. And to keep getting traffic at a high level as well as continue earning revenue from affiliate marketing, or advertising products, you need a standard host and a super-fast website for both mobile and desktop users.

The GTmetrix tool gives the clear report of every internal/external CSS file that may be causing issues with the site loading speed.

With this tool, you can easily detect possible elements that are accountable for the slowing down of your website speed both on mobile and desktop devices and then take the necessary action to fix it.

Most people are used to the Google PageSpeed Insights, but this is nowhere to be found when it comes to giving detailed reports to work on.

Another fantastic thing I like about the GTmetrix tool is that it provides me a weekly report as regards my site speed.
