We analyzed page load time and found that the first response time was 2.5 sec and then it took 40.6 sec to load all DOM resources and completely render a web page. This is an excellent result, as only a small number of websites can load faster. Unfortunately, there were 21 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

Page optimization

  • HTML 78.0 kB
    Images 3.6 MB
    Javascripts 370.8 kB
    CSS 351.5 kB

    In fact, the total size of main page is 4.4 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 3.6 MB which makes up the majority of the site volume.

    • Original 78.0 kB
    • After minification 61.0 kB
    • After compression 10.1 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 16.9 kB, which is 22% 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 67.9 kB or 87% of the original size.

    • Original 3.6 MB
    • After optimization 3.3 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. Ref images are well optimized though.

    • Original 370.8 kB
    • After minification 317.0 kB
    • After compression 90.8 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 280.1 kB or 76% of the original size.

    • Original 351.5 kB
    • After minification 266.5 kB
    • After compression 51.3 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 300.2 kB or 85% of the original size.

Our browser made a total of 150 requests to load all elements on the main page. We found that 55% of them (82 requests) were addressed to the original, 13% (19 requests) were made to and 7% (10 requests) were made to The less responsive or slowest element that took the longest time to load (20.3 sec) belongs to the original domain

Additional info on


The browser has sent 117 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Ref. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 37 to 1 for JavaScripts and from 16 to 1 for CSS and as a result speed up the page load time.

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) and no language is claimed in <html> or <meta> tags either. 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.

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.

Social Sharing Optimization

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