What I actually wanted to ask was if I can use Links Manager 3.7.0 for links to sites that are of interest to our customers, i.e. magazines that have articles or museeums that have objects that relate to our product lines without necessarily having any links back from them. This since I have not found any easy way within ZenCart to do this.
You can add links from the admin page to anyone you wish. Doing this still allows link manager to track clicks. You can also hand enter links/ads with in the sidebox by editing, adding links where it says.

//other ads can go here

Back links are not required.
