In which sections of the “Categorization Page” promotional goods and services will be displayed?

Categorization Page: On this page, when a user enters to one of the site categorizations, products will be arranged and displayed based on advertisements by default. If a user clicks on a product link, one number of click will be reduced from the total number of clicks. It should be noted that if a user clicks on a product link for several times within a specified time period by us (by default, 10 minutes), only one number of "Click Count" will be reduced.
Left side of the categorization page: When a user enters to one of the site categorizations, a number of related random advertisement will be displayed at the left side of the categorization page and for each view, one number will be reduced from the total number of views and if users click on the product link, one number of “Click Counts” will be reduced from the total number of clicks too. It should be noted that if a user sees a single ad for several times and clicks on the product link within a specified time period by us (by default, 10 minutes), only the first time will be calculated. 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.
