Our browser made a total of 143 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original, 67% (96 requests) were made to and 20% (28 requests) were made to The less responsive or slowest element that took the longest time to load (3 sec) relates to the external source

Additional info on


The browser has sent 137 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Auto Atlas. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 27 to 1 for JavaScripts and as a result speed up the page load time.











Possible request optimization













Normal result


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

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


CS cs 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 Czech. Our system also found out that main page’s claimed encoding is windows-1250. 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

Country of origin for 76% of all visits is United States. It lies approximately 5070 miles away from the server location (Czech Republic) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to United States or just closer to the user base.

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:
