I have a query before purchasing the plan.

When you said that "With the plugin’s help, you’ll be able to get a PageSpeed score as high as 100 across all your web pages!"
What did you mean by PageSpeed? Is it "Google PageSpeed Insights"? I have tested your official website (https://rabbitloader.com) and got only a "58 score" for the mobile. so isn't help for the mobile score?
