Hi,
the URL reported is wrong, it's not properly routed to any Joomla menu item so you have issue even with meta tags.
http://www.hotelcitypc.it/component/content/article/92-offerte/62-mercato-dei-vini-dei-vignaioli-indipendenti?Itemid=993
You have to properly set a menu item routing to the article 62-mercato-dei-vini-dei-vignaioli-indipendenti to have replaced the part '/component/content' with the menu alias and to have removed the part '?Itemid=993'
Probably you are missing a menu item linking that category of articles or articles itself.
Best regards
