Pizza a Domicilio, keywords removed?

For some strange reason if now I search pizza a domicilio on google.it, I'm not able to see any more my website www.pizza-a-domicilio.it. I don't know what is going on, but as you can imagine, I am not happy with it.

So, let's start using some of the domains I maintain for some keyword linking.

• Page Rank 4: http://www.prezzibenzina.it (top of all pages, keyword pizza?)
• Page Rank 3: http://poi.prezzibenzina.it (top of all pages, keyword pizza a domicilio)
• Page Rank 3: http://gallery.prezzibenzina.it (top of all pages, keyword trova pizzerie)
• Page Rank 3: http://www.evoluzioni-italia.it (bottom of the home page, keyword com)
