Page optimization

  • HTML 34.7 kB
    Images 755.1 kB
    Javascripts 269.9 kB
    CSS 203.6 kB

    In fact, the total size of main page is 1.3 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 755.1 kB which makes up the majority of the site volume.

    • Original 34.7 kB
    • After minification 30.6 kB
    • After compression 7.1 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. This page needs HTML code to be minified as it can gain 4.2 kB, which is 12% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 27.7 kB or 80% of the original size.

    • Original 755.1 kB
    • After optimization 690.6 kB

    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. ESO images are well optimized though.

    • Original 269.9 kB
    • After minification 269.9 kB
    • After compression 89.2 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 180.6 kB or 67% of the original size.

    • Original 203.6 kB
    • After minification 200.9 kB
    • After compression 26.0 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. needs all CSS files to be minified and compressed as it can save up to 177.6 kB or 87% of the original size.

As for redirects, our browser was forwarded to before it reached this domain.

IP address uses IP address which is currently shared with 3 other domains. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Our service has detected that German is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that 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.

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:
