We analyzed page load time and found that the first response time was 157 ms and then it took 2.9 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 45% of websites can load faster.

Page optimization

  • HTML 132.1 kB
    Images 169 B
    Javascripts 411.0 kB
    CSS 0 B

    In fact, the total size of main page is 543.3 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 75% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 411.0 kB which makes up the majority of the site volume.

    • Original 132.1 kB
    • After minification 132.0 kB
    • After compression 29.3 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 102.8 kB or 78% of the original size.

    • Original 169 B

    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. KAYAK images are well optimized though.

    • Original 411.0 kB
    • After minification 410.3 kB
    • After compression 143.1 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 267.9 kB or 65% of the original size.

Our browser made a total of 80 requests to load all elements on the main page. We found that 28% of them (22 requests) were addressed to the original, 16% (13 requests) were made to and 10% (8 requests) were made to The less responsive or slowest element that took the longest time to load (609 ms) relates to the external source

Additional info on


The browser has sent 79 CSS, Javascripts, AJAX and image requests in order to completely render the main page of KAYAK. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 25 to 1 for JavaScripts and from 5 to 1 for CSS and as a result speed up the page load time.











Possible request optimization













Normal 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

Good result


KO ko language flag


KO ko 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 Korean is used on the page, and it matches the claimed language. 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.

Poor result

Visitor World Map

Country of origin for 100% of all visits is South Korea. It lies approximately 4670 miles away from the server location (Sweden) 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 South Korea or just closer to the user base.
