Page optimization

  • HTML 74.4 kB
    Images 955.8 kB
    Javascripts 682.1 kB
    CSS 137.4 kB

    In fact, the total size of 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. 70% of websites need less resources to load. Images take 955.8 kB which makes up the majority of the site volume.

    • Original 74.4 kB
    • After minification 65.1 kB
    • After compression 14.5 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 9.3 kB, which is 13% 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 59.9 kB or 81% of the original size.

    • Original 955.8 kB
    • After optimization 945.5 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. Astrobio images are well optimized though.

    • Original 682.1 kB
    • After minification 618.5 kB
    • After compression 184.1 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 498.0 kB or 73% of the original size.

    • Original 137.4 kB
    • After minification 125.6 kB
    • After compression 35.9 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 101.5 kB or 74% of the original size.

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

IP address uses IP addresses which are currently shared with 6 other domains. The more sites share the same stack of IP addresses, 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

Normal result


N/A  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 English. 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.
