This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Images take 2.9 MB which makes up the majority of the site volume.

We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 28 to 1 for JavaScripts and from 11 to 1 for CSS and as a result speed up the page load time.
