Warnings

Site network waterfall tool provide information about resource diagnostic:

  • Render blocking resources: resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
  • Optimize cache policy: serve static assets with an efficient cache policy. A long cache lifetime can speed up repeat visits to your page
  • Optimize images: optimized images load faster and consume less mobile data
  • Use responsive image: serve images that are appropriately-sized to save mobile data and improve load time
  • Use webp image: serve images in next-gen formats like jpeg 2000, jpeg xr and webp which means faster downloads and less data consumption
  • Remove unused css rules: remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity
  • Minify javascript: minifying JavaScript files can reduce payload sizes and script parse time
