Harmony Headbands review for Booster: Page Speed Optimizer

Hi there, thanks for the review. You are absolutely correct, the app will not show any increase or decrease in GTmetrix or any other tool. From our FAQ on the dashboard of the app: https://share.getcloudapp.com/NQugzdW0 ----------- Important Notice: This app will not increase or decrease any pageload speed metrics such as Pingdom or Gmetrix. The app preloads links, which only works from the second page view. These apps DO NOT account for second page load times in their results. ----------- The app utilizes open source software (https://github.com/instantpage/instant.page) to preload links on your theme, thus speeding up loading times after the first page load. As mentioned throughout the app, some themes already include this open source code by default. As a result, these themes wouldn't see any increase in speed because the code is already present. Cheers Stuart
