  • Encoding

    ISO-8859-1

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Tmobile.de can be misinterpreted by Google and other search engines. Our service has detected that German is used on the page, and it matches the claimed language. Our system also found out that Tmobile.de main page’s claimed encoding is iso-8859-1. 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.
