Click is a type of action when the customer actually clicks on the advertisement with a link to a certain web page. All clicks are tracked by HasOffers.
Data category indicates Data Orders with large amounts of aged leads.
Other category is used for Partner Offers.
Partner Offer mechanism allows advertisers using PX offers in order to buy traffic driven by PX publishers and receive clicks and conversions. In contrast to usual PX offers, you do not control what happens between the time when a user clicks on the banner and when you receive a conversion pixel. Consequently, there is no lead processed by PX platform.
