Pages not being hidden |

I am trying to hide my supplies pages so that only customers who are given the link can see them. I installed Hide from Search website and on my page called Supplies I clicked the both check boxes regarding hiding the page. when I do a search for supplies that page is still the first thing that shows up in my search. Am I doing something wrong? I have tried a couple other plug ins already and am really hoping this one will work after reading the excellent reviews. Thanks!

The page I need help with: [log in to see the link]
