Key Findings

We analyzed Wkw.cz page load time and found that the first response time was 501 ms and then it took 20.7 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 was 1 request timeout, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

Search Engine Optimization Advices

Language and Encoding

  • Language Detected

    CS

  • Language Claimed

    CS

  • Encoding

    WINDOWS-1250

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Wkw.cz can be misinterpreted by Google and other search engines. Our service has detected that Czech is used on the page, and it matches the claimed language. Our system also found out that Wkw.cz 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.

Social Sharing Optimization

wkw.cz

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