  • Encoding

    BIG5

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Hi-av.net can be misinterpreted by Google and other search engines. Our service has detected that Japanese is used on the page, and it does not match the claimed Chinese language. Our system also found out that Hi-av.net main page’s claimed encoding is big5. 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

hi-av.net

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