Page optimization

  • HTML 50.3 kB
    Images 1.3 MB
    Javascripts 398.2 kB
    CSS 37.3 kB

    In fact, the total size of Arvo.org main page is 1.8 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 30% of websites need less resources to load. Images take 1.3 MB which makes up the majority of the site volume.

    • Original 50.3 kB
    • After minification 46.0 kB
    • After compression 13.4 kB

    HTML optimization

    HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 36.9 kB or 73% of the original size.

    • Original 1.3 MB
    • After optimization 1.3 MB

    Image optimization

    Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. ARVO images are well optimized though.

    • Original 398.2 kB
    • After minification 335.1 kB
    • After compression 108.4 kB

    JavaScript optimization

    It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 289.8 kB or 73% of the original size.

    • Original 37.3 kB
    • After minification 27.4 kB
    • After compression 7.6 kB

    CSS optimization

    CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Arvo.org needs all CSS files to be minified and compressed as it can save up to 29.7 kB or 80% of the original size.

Social Sharing Optimization

Open Graph description is not detected on the main page of ARVO. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
