How promotional products will be displayed on the “Product Details” page?

When users view the information of a product, a number of random promotional products related to the same categorization will be displayed at the right side of the product details page and for each view, one number will be reduced from the total number of views and if users click on a product link, one number of “Click Counts” will be reduced from the total number of clicks. It should be noted that if a user sees a single ad for several times within a specified time period by us (by default, 10 minutes), only one number of "View Count" will be reduced from the total number of purchased views.

Please note that, those advertisements will be displayed at this section, that the owner of the product have purchased both “Click Counts” and “View Counts” services.
