This report generated gives you a detailed breakdown of your PageSpeed score, YSlow score, and a list of recommendations on what you can change to improve your page load time. Anything below a Performance score of “A” means there is room for improvement.
All the reports that have been completed are available under the “Reports” section (meta box) as shown in the below screenshot.

Individual reports can be expanded to view the summary of page speed scores, Yslow scores, load times, and other details, as shown in the above screenshot.

For a detailed report, click on its link; it will take you to the GTmetrix web page, where you can view it in-depth. A sample report can be seen in below screenshot 15.
The detailed report is divided into different tabs. First, you will see your PageSpeed score, with different ranking items listed with their score.
Green items are good and don’t need your attention. Red items are slowing down your website and require further investigation.

Step 7: Schedule Tests (Optional)
You can also schedule the page load tests to run hourly, daily, weekly, or monthly. By default, scheduled tests always use the Vancouver, Canada, test server region.
The test will automatically run at the frequency you choose. The admin will be notified when the test completes and one of the following conditions is met:
- Page Speed score is less than A, B, C, D, E, or F
- YSlow score is less than A, B, C, D, E, or F
- Page load time is greater than 1, 2, 3, 4, or 5 seconds
- Page size is greater than 100 KB, 200 KB, 300 KB, 400 KB, 500 KB, or 1MB
