We analyzed page load time and found that the first response time was 490 ms and then it took 1 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 15% of websites can load faster.

Page optimization

  • HTML 19.0 kB
    Images 2.0 kB
    Javascripts 0 B
    CSS 1.9 kB

    In fact, the total size of main page is 22.8 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only 10% of websites need less resources to load. HTML takes 19.0 kB which makes up the majority of the site volume.

    • Original 19.0 kB
    • After minification 15.8 kB
    • After compression 3.0 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 3.2 kB, which is 17% 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 16.0 kB or 84% of the original size.

    • Original 2.0 kB
    • After optimization 1.9 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. Zaval images are well optimized though.

    • Original 1.9 kB
    • After minification 1.6 kB
    • After compression 306 B

    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 1.6 kB or 84% of the original size.

Our browser made a total of 19 requests to load all elements on the main page. We found that all of those requests were addressed to and no external sources were called. The less responsive or slowest element that took the longest time to load (490 ms) belongs to the original domain

Additional info on


The browser has sent 18 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Zaval. According to our analytics all requests are already optimized.







Possible request optimization









Good result

IP address uses IP address which is currently shared with 1 other domain. 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


EN en language flag


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. Our service has detected that English 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 iso-8859-1. 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 Italy, 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.

Social Sharing Optimization

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