Here is a quick thought for everyone.

Create a basic .html file that includes a list of all of the links you would like to display.  Create an array for each URL weighting when it will be viewed (how frequently) and the # of links to display per page (this can be set separately on each originating page).  If you have a 10,000 page catalog, you don’t want to have 15 links showing on every page- its obvious your goal is to receive links from your other web properties.  Instead, display a random rotation of 15-20 links (to deeper parts of your sites, too)
