    Remove render-blocking JavaScript

      How can I fix - Revome the following errors to improve Speed for Website.

      Here are the following errors I got :


      1. JavaScripts that are not critical to initial render should be made asynchronous or deferred until after the first render. Bear in mind that for this to improve your loading time, you must also optimise CSS delivery.

      2. If the amount of data required exceeds the initial congestion window, it will require additional round trips between your server and your visitor’s browser. To make pages load faster, limit the size of the data that is needed to render the above-the-fold content of your page.

      3. Images often account for most of the downloaded bytes on a page. Properly formatting and compressing images can save many bytes of data and improve website performance.


      Your page has 1 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.

      None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
