When visitors using mobile devices in portrait mode (vertical view) the list of ads in categories, searches and all parts can be seen one by one and it is exactly like Instagram.
Users and visitors of the site should be able to see a large number of lists at a glance and save their time, in its current state, it looks more like Instagram to me than a classifieds and directory website. Please, as the lists are displayed well for the desktop version and landscape mode, an arrangement should be adopted so that viewing is easier and more beautiful for mobile and vertical and portrait mode.
