You can simply create banner blocks from BANNER MANAGER with available options for positions. However, in order to have immensely more choices, you should go with WIDGETS afterward. With Widgets, you can choose all or any pages on your website to set banners.
For example, if you select “All Product Types”, you can post to all items belonging to this group or select only one or several ones. Depending on the chosen page, you continue to have many positions correspondingly.
Because in Widgets there are more specific groups and pages for you to opt for, the number of positions is also significantly higher than creating banners in the usual way. Hence, banner content would be more close to page content at the same time.
