See Where Links Lead Before You Click

In Safari, you can see where a link on a page goes before you click it. Just hover your cursor over the link and look at the bottom left corner of the Safari window. If you don’t see the URL appear there, then check to make sure you have the Status Bar turned on by going to View, Show/Hide Status Bar. But keep in mind that if the site uses a URL shortener or link service that you may not be looking at the final destination.
