Ability to access the cart from any page
A customer in a regular store can always see what items they have selected by checking their shopping cart. Provide your clients with a similar opportunity — they should be able to check the “Cart” at any moment and from any page of the site.
Note
To determine the number of users from the Yandex Advertising Network who placed an order on your site, set the order confirmation page as a goal (the desired outcome of the ad campaign).
