1. Go to the site that you want notifications for.
2. If the site allows notifications you will get a pop up asking if you want to receive notifications from them
A site that i use with notifications is Fox News. This link i posted even though it says Mavericks its still the same for yosemite.

To view and disable sites (not for adding) while in safari, go to top menu bar >>safari>>Preferences>>Notifications.
