The Conditional Tags of both WooCommerce and WordPress can be used in your Template files to change what content is displayed based on what conditions that page matches. For example, you might want to display a snippet of text above the shop page. With the is_shop() Conditional Tag you can.
Since WooCommerce uses custom post types you can use many of WordPress’ own conditional tags too. See: http://codex.wordpress.org/Conditional_Tags.
Warning: You can only use conditional query tags after the posts_selection action hook in WordPress (the wp action hook is the first one through which you can use these conditionals). For themes, this means the conditional tag will never work properly if you are using it in the body of functions.php, i.e. outside of a function.
