Page speed optimisation

Especially with mobile but also on desktop my page is not optimized and is likely to deliver a slow user experience You know your job is finished when pageSpeed Insights shows a score of at least 85/100 for my webpage and all it's 18 pages for both mobile and desktop. My page has some blocking script resources and some blocking CSS resources. This causes a delay in rendering my page. Your job is to sort that out plus you will need to leverage browser caching. Page insights says: Your page has 4 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. Remove render-blocking JavaScript: Optimize CSS Delivery Leverage browser caching Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
