Page optimization

  • HTML 6.4 kB
    Images 126.3 kB
    Javascripts 0 B
    CSS 16.6 kB

    In fact, the total size of main page is 149.2 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only 5% of websites need less resources to load. Images take 126.3 kB which makes up the majority of the site volume.

    • Original 6.4 kB
    • After minification 6.2 kB
    • After compression 1.6 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 4.8 kB or 76% of the original size.

    • Original 126.3 kB
    • After optimization 119.7 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. Ruediger Kramer images are well optimized though.

    • Original 16.6 kB
    • After minification 14.0 kB
    • After compression 2.3 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 14.2 kB or 86% of the original size.

Possible request optimization









Good result

IP address uses IP address which is currently shared with 4 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.

Language and encoding

Poor result


N/A  language flag


DE de language flag





Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else), while the claimed language is German. Our system also found out that main page’s claimed encoding is windows-1252. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

HTTPS certificate

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

Normal result

Visitor World Map

The server of is located in Germany, but, unfortunately, we cannot identify the countries where the visitors come from and thus it’s impossible to define if the distance can potentially affect the page load time.

Good result

Poor result

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:
