  • Encoding

    N/A

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Radiojavan.com can be misinterpreted by Google and other search engines.

Our system also found out that Radiojavan.com main page’s claimed encoding is . 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.
