Banners.

From Smart Job Board help

If needed you can change the default location of any banner on the front-end.

 Note: Use the "Highlight Templates on the front-end" function to find the needed template to edit.
 See the "Design Modification Guidelines" section to get the instructions how to enable this function. 

To move a banner to another place on the page you need to find the banners group code:

{module name="banners" function="show_banners" group="Side Banners"}

cut it and insert to the needed place of the same or another template.

 Note: banners size and other settings can be modified via Admin Panel.
 Instructions to make that you can find in the “Banners” section of the Manual.
