Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Irdta.eu can be misinterpreted by Google and other search engines. Our service has detected that English is used on the page, and it matches the claimed language. Our system also found out that Irdta.eu main page’s claimed encoding is utf-8.
