Online Website Speed Analyzer: GTmetrix

The speed of a website is a very important factor for providing a better browsing experience to visitors (which directly effects the success of a website).

Specially, after Google announced that "speed" became one of the elements in its search ranking, it is clear that web designers/developers should be focusing more on this.


GTmetrix is a free and online website speed analyzer which uses Google Page Speed and Yahoo YSlow as the analyzing engines and display their results + recommendations online.

It enables you to compare multiple URLs and, once signed up, you can:

  • view the past tests ran to compare with the current results
  • schedule daily/weekly/monthly automated checks
  • save reports
  • set any report to be public or private

GTmetrix also has a bookmarklet which you can run a test for any website with a click.

    content quality > speed

    Google will still show sites with better quality content first before sites with poorer quality content, even if the speed of the poorer ones are faster than the better one.

    Thanks for pointing on GTmetrix page speed analyzer!
    However, although the speed of the site is important, still the content is the first thing that matters.
