There are two ways to view your storefront, as a visitor browsing the site and as a logged in customer of yours.
To see your site as a visitor would, simply click Storefront in the bottom left of your account. Make sure to then click Sign Out, to be taken to the home page, if that's what you'd like to see. If you don't click Sign Out, you'll see the catalog page, just like your signed in users will see.
To see your site as a logged in customer, navigate to People and click the Impersonate icon beside the name of the person you want to see the store as.
