I went from an F/E rating to an A/B rating using this tool to help point me to areas on the website front page that were contributing to noticeably slow loading times.

I put in the API and the email that it asked for and it never shows the results. But when I go to it shows the credits as being used. Edit*** It must’ve just needed a little more patience on my end. The plugin is working.

After using GT Metrix I found out how my website really was presented to final visitors. Simple to use and configure, information provided has an immense value to find bottlenecks and improvement points. Add this to your site toolkit as you’ll need it!
