Visit qt.orgWe analyzed Qt.org page load time and found that the first response time was 963 ms and then it took 24.8 sec to load all DOM resources and completely render a web page.

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Qt.org 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 Qt.org 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.
