In the Product Performance area you will see two columns: Impressions and Clicks.
The first shows how many times your product has been seen on the page. This means that every time a viewer loads the page where the product is displayed, the number of Impressions will go up by one.
Clicks, instead, indicates the number of times a viewer actually clicks on the products and starts a search on the affiliate website. Please note: a click does not necessarily turn into a booking.
This is why it is really important that each product is implemented in the best way possible, to maximise your product efficiency.
