Each banner that is used to advertise or display information can be linked to another website page.  This page can be be set in the administration dashboard.  The following tutorial will guide you through the process to determine the link path or partial URL used for each Banner. 

How determine the banner link in OpenCart 1.5

1. Login to the Administration Dashboard as an Administrator
2. Hover over SYSTEMS, then click on DESIGN and then select BANNERS. Then you will see the initial window for Banners appear as per below:
   
   
   
   
   
   
3. Select a Banner name and then select EDIT to edit the group
   
   
4. Look into the chart search for the column labeled LINK.  The link assigned to the banner will only include the part of the URL path AFTER the domain for the OpenCart 1.5 store.  For example:
   
   If the entire URL for the product is http://storeurl.com/index.php?route=product/manufacturer/product&manufacturer_id=7 then you will need to separate the STORE URL from the product path.  This is how the example path would be broken up:
   
   Store URL = http://storeurl.com
   Product Path = /index.php?route=product/manufacturer/product&manufacturer_id=7
   
   Take the product path and then paste it into the blank for the link.  Note path used for the banner doesn't have to necessarily link to a product page.  It could also be an information page or other part of the store
   
5. Once you have finished editing the banner link(s), select SAVE in the top right hand corner to save your changes

The changes that you have made to the URL will enable the banners to link to further information that can give your customer a more detailed look at a product or communicate further information that you need to pass to your customer.
