Page optimization

  • HTML 10.1 kB
    Images 0 B
    Javascripts 263.4 kB
    CSS 132.4 kB

    In fact, the total size of Json.cn main page is 405.8 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 20% of websites need less resources to load. Javascripts take 263.4 kB which makes up the majority of the site volume.

    • Original 10.1 kB
    • After minification 9.6 kB
    • After compression 3.6 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 6.6 kB or 65% of the original size.

    • Original 263.4 kB
    • After minification 227.3 kB
    • After compression 78.9 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 184.5 kB or 70% of the original size.

    • Original 132.4 kB
    • After minification 132.1 kB
    • After compression 23.5 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. Json.cn needs all CSS files to be minified and compressed as it can save up to 108.9 kB or 82% of the original size.

Requests

The browser has sent 18 CSS, Javascripts, AJAX and image requests in order to completely render the main page of JSON. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 12 to 1 for JavaScripts and as a result speed up the page load time.

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Json.cn can be misinterpreted by Google and other search engines. Our service has detected that Chinese is used on the page, and it matches the claimed language. Our system also found out that Json.cn main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.

SSL Certificate

Json.cn has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.

Social Sharing Optimization

Open Graph description is not detected on the main page of JSON. 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:
