Your page has 2 blocking script resources and 7 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.
Optimize CSS Delivery of the following:
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.
Leverage browser caching for the following cacheable resources:
https://static.doubleclick.net/instream/ad_status.js (15 minutes)
https://www.googletagmanager.com/gtag/js?id=UA-51662211-1 (15 minutes)
https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js (60 minutes)
https://www.google-analytics.com/analytics.js (2 hours)
Thanks a lot John
