Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Dnf.no can be misinterpreted by Google and other search engines. Our service has detected that Norwegian is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that Dnf.no 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.
