My business is a Hotel Management School in Switzerland

the other schools i want to compare too since they seem well placed in google are Les Roches, Glion

the SEO comparison shows me that other schools use xxxx keywords

Les Roches uses: xxxx

Glion uses: xxxxxx

For IMI i suggest to use following 7 keyword combinations: xxxxx,xxxx xxx,

Yes the school seems to be ok for Wikipedia since it is rather old, i can refer to many facts like for example its participation during the House of Switzerland project in Bejing Olympics 2008 and the creation of a first international student guide for the iphone
